Some clarity around Trunk training

With the initiation of a third lock down in the UK we thought it would be a great idea to engage our readers in some motivating posts to help keep you motivated.  We welcome back APA coach Konrad McKenzie with a weekly guest post.

This blog will be a follow on from my initial blog around training the core, it was inspired by a webinar I had listened to on “Trunk Training” kindly put together by Alex Wolf. I wanted to write about what I learnt on this talk in order to spread the word and create some real clarity on training the mid-section. I will mention some of the pertinent topics that Alex discusses and would like to stress that the issues discussed are from his presentation rather than my own. This blog, as the presentation was outlined, will be divided into several parts;

  • Functional anatomy
  • Trunk Function
  • Why we need to consider the hip when talking about the Trunk
  • Exercise classifications
  • Exercise functionality and coordinative demands

Consider for a moment this picture of a bonnet. How much faith would you have in a car mechanic who did not know the parts of a car, could not identify what the problems were or the tasks that could be done to solve the problem? Funnily enough, not too long ago I broke down and had to rely on a car mechanic to solve an issue with my car. He did so meticulously.

Some questions that arose from the presentation were;

What does the trunk actually do when completing a task?

What do we have available to optimize trunk function?

When we can define the function of the trunk, we are able to align the most appropriate training methods we can to create real clarity of outcomes. This is something I believe the best practitioners out there have, clarity.

 

Functional anatomy

Similar to my blog around shoulder health I will break this blog down into two parts the Local and Global system. In the case of the trunk, both systems help to stabilise the trunk.

Local system

Local system is mostly made up of deep intrinsic musculature, which are attached closer to the vertebrae and are attached onto the spinal processes feeding into the ribs. The total volume of these muscles is small and (in terms of muscle architecture) are vertically orientated along the spine which highlights how the muscles operate and their force production capabilities. Muscles of the local system typically support spinal segmental control, are highly resistant to fatigue and anticipatory in nature (Feed forward mechanism). These muscles (to name a few) include the multifidus, Diaphragm and Pelvic floor and deeper fibres of the Erector Spinae. Structurally, the ligamentous (non- contractile) structures also provide segmental control and spinal stability. Historically, the term ‘Core stability’ came from spinal segmental control and the deeper intrinsic musculature.

Global system

The Global system has larger more superficial musculature, which span many joint segments. Unlike the local system these muscles are more obliquely orientated thus, high force production capabilities and they initiate gross movement. Comparatively, the global system has lower fatigue resistance but this particular system provides stability and mobility to the spine. These muscles include the external/internal oliques, superficial fibres of the Erector Spinae and Rectus Abdominis.

Trunk Function

Muscles of the Trunk produce force to serve a few roles. Particularly in Generation, Transfer and Control. I will briefly highlight these in more detail

 

Generation

Transfer

Control

·         Rotation

·         Block Rotation

·         Flexion and Extension

·         Lateral flexion and extension

·         Proximal to distal

·         Lower to upper body

·         Posterior to Anterior

·         Medial to Lateral

·         Postural control

·         Resist deformation to external and  internal forces

 

Generation

This refers to the force generation capabilities, a recent topic of conversation in strength and conditioning is whether the trunk is designed to create/block rotation or both. Supporters of Block rotation suggest that the stiffening of trunk allows the arms and legs to work against it, rather than having a continuation of the movement which may dampen performance outcomes.

Transfer

Quite a common conclusion in strength and conditioning circles is that the trunk acts to transfer forces in athletic movements, through different planes of motion.

Control

Resisting deformation by external and internal forces, a useful example of external forces was a scrum in Rugby union as players have to manage external forces from the opposition. Internal forces refers to force that we ourselves generate.

 

Why we need to consider the hip when talking about the Trunk

Some may have heard the term “Regional interdependence” the notion that all systems of the body are interconnected meaning that we cannot ignore the fact that large amount of abdominal muscles attach to the hip and pelvis. Therefore, dysfunction in the hips can lead to problems in the spine. Two notorious mal-alignments mentioned were posterior and anterior pelvic tilt. I will briefly describe anterior pelvic tilt as it’s the most prevalent issue I see.

Anterior Pelvic tilt (APT)

APT or lower crossed syndrome is characterised by a rolling forward of the pelvis due to shortening of the hip rectus femoris, Iliopsoas and the weaknesses of the deep abdominal musculature causing issues in the spine at the L4-L5 level.

 

Exercise classifications

In this particular section I will not deep dive into everything that was mentioned, this blog would simply be too long. However, I am quite open to having conversations on this. What I liked about this presentation and paper is the clarity on the intention of each exercise classification, something I am going to use in my programming to add the extra layers of detail. The “what and the how”.

Function is defined by its intended outcome, it is not how an exercise looks in relation to the performance task

Alex has a great paper Spinal-Exercise Prescription in Sport: Classifying Physical Training and Rehabilitation by Intention and Outcome. The physical outcomes presented in his research were split up into four overarching qualities with further sub-classifications, which I will touch upon.

Just for the benefit of the reader the exercises were also further sub-classified described as functional and non-functional (NF). Functional (F) being exercises which allow their athletes to move in all planes of movement, for example a Squat. Non-functional exercises (example a side plank) are typically performed in partial weight bearing positions (single, lying kneeling etc) and across a single plane of movement (Spencer et al, 2016).

 

A)  Mobility (F) and (NF)Exercises used to develop, maintain, or restore global spine range of movement.

 

B)  Motor control- referred to as the maintenance of spinal integrity during a skill movement task. This is not only a result of the capacity of muscles but also on the ability to process sensory input.

This was further subdivided into;

1)  Segmental stabilisation (NF)

2)  Spinal disassociation (NF)

3)  Spinal disassociation (F)

4)  Segmental movement control (NF)

 

C)  Work capacity- The same as local muscular endurance, defined as the ability to tolerate varying intensities and durations of work.

This was further subdivided into;

  • Pillar conditioning (NF)
  • Pillar conditioning (F)
  • Segmental conditioning (F)
  • Segmental conditioning (F)

 

D) Strength- The ability for muscles to produce force.

    This was further subdivided into;

    • Pillar Strength development
    • Stiffness development
    • Power development

     

    As mentioned going into each sub-classification would be too lengthy and I will reference the article. However, I thought this was useful to organise exercise prescription by working backwards from the outcome!

     

    Exercise functionality and co-ordinative demands

    As part of Alex’s reflections on this paper he highlights an important topic “coordination” this is not going to be the usual way of thinking about coordination, but to describe it as truly functional to an athletic movement the muscle-tendon interaction of both tasks need to be identical, down to the;

    • Magnitude of contraction (How much)
    • Rate of contraction (How quick)
    • Timing of interaction (When)
    • Timing of interaction and contraction (How)

     

    “Unless there is a real identical muscle-tendon interaction (coordination) between tasks, it cannot and never will be functional. Therefore functional, within the article should be redefined as F= Multi-jointed & NF = isolated”.

     

    Interestingly, a point was made that the “Greatest success of achieving intended outcomes has been through NF exercises modalities”. Why? Because isolated exercises target specific tissues that need to be trained i.e. we are going directly to the horse’s mouth.

    Thanks for reading this article, it was not intended to give you specific exercises rather an explicit framework for you to build your exercise program on.

    The Load Management Puzzle

    With the initiation of a third lock down in the UK we thought it would be a great idea to engage our readers in some motivating posts to help keep you motivated.  We welcome back APA coach Konrad McKenzie with a weekly guest post.

     

    This lockdown 3.0 I have been fortunate to gain some more knowledge from leading practitioners in strength and conditioning & sport science.  A few weeks ago I took part in webinar on load management by Dario Novak. This webinar series had interesting speakers on it including professor Ales Filipcic and Matt Little who currently leads Andy Murray’s strength and conditioning programme. This series inspired me to share the information and perhaps create more conversations around monitoring using some of my own thoughts.

    I will be first to admit that this was something I struggled with in the first years of coaching. Not so much the theory behind it, rather the implementation in highly dynamic environments. Usually, it is much easier to monitor this if you have  large sports science departments who can meticulously monitor training readiness, volume, quality & intensity of training. As mentioned in my previous blog (Keeping athletes shoulder healthy) training volume is a large stakeholder when trying to reduce injury.

    This blog will not go into all the different monitoring methods but will discuss the following:

    • Why do we want to collect data on player’s health and performance?
    • Painting the picture
    • Do we need to look at session content?
    • What we can start off by doing
    • Practical implications

     

    What and why do we want to collect data on player’s health and performance?

    I am going to split this into two sections to make it more reader friendly.

    What do we want to collect on player’s data health and performance?

    A range of metrics can be collected in my opinion, the higher the level of the athlete the more in depth analysis needs to be. Metrics include (not an exhaustive list):

    Player’s physiological and anthropometric  data

    Other metrics include time characteristics, in the case of Tennis these are:

    Time characteristics

    • Start time
    • Session time
    • Active time
    • Average rally time
    • Average real time

    Why do we want to collect data on player’s health and performance?

    Measuring a player’s health is important for longevity and injury prevention. We are all aware that high performance sports is brutal on the body.  If we think about the game of tennis for example, a high level junior player rapidly putting the brakes on when travelling at 6m/s is experiencing 3-6 times their bodyweight on each leg. Not only does this place structural and neurological stress on the body, training and competition can take a psychological toll on the human body. Additionally, those who work with growing athletes will also know the physiological stress around growth and maturation. In simpler terms we want to use data to:

    • Keep players healthier
    • Prevent OT & Burnout
    • Aim to Reduce Injuries

    Painting the picture

    “It is better to measure something than nothing”

    This was a quote that stood out to me from the webinar. I wanted to further add that it is also important to know what you are measuring and more importantly how you are going to use the data. Sounds obvious I know but it’s easy to get lost in a sea of data collection that will have no actionable consequences on day to day practices.  It is important that we use loading data to paint the picture of the athletes we are working with. Pertinent questions from the webinar regarding data collection were:

    1. What kind of data/info do we use for planning?
    2. How do we treat and approach our players?
    3. How do we collect and store player’s data?
    4. How many different aspects of training do we work in the training process?
    5. What is the role of players in the training process?
    6. How are the players responding to load?

    Do we need to look at the session content? Some food for thought

    Although when they spoke about session content it wasn’t focused on youth athlete training, it is a passion point of mine and definitely created some food for thought around this area. It was highlighted that a typical academy tennis session would be very high in volume and not high enough in terms of intensity.  The current training volumes may not be tolerable for a growing athlete. Also, if 60-80% of the average rally is over in 4-5 shots, are the current training volumes reflective of the game? This is an interesting question. My personal thoughts are, is there a period where we overload the volume? A period where we intensify in skill training load?  So, on different training days and/or phases we emphasize volume or intensity.

    A primary question from the webinar was do we know what types of load we are exposing our players to? Is this reflected in the session? Some humbling questions.

    It is quite common to see a session start with high volume drilling and end with high intensity match play. This webinar was in Tennis, however I see this across the board in a lot of field and court sports. Perhaps, flipping this structure will allow for a more optimal session, makes sense from a scientific point of view. Something for the skills and strength and conditioning coaches to converse over.

    What we can start off by doing

    Using Minutes alone, is not a good indicator of session load, without content of the session e.g. (Volume, intensity, quality)

    There are countless articles and papers by people who are much smarter than me on this topic so I am not going to dive into any monitoring tools. I will link the reader to this article which I found informative.  But I wanted to highlight an idea which may be overlooked and that is categorising sessions. I have tried to do this over the years working with technical coaches to identify different types of sessions. For example, high and low intensity days. But we can go even deeper and distinguish between high intensity match play and high volume drilling. Furthermore, we could pair this with conditioning sessions which complement the type of loading from skill work. Vertical integration is popular in the domain of Rugby union and football and I am a firm believer in learning from different sports.

    Practical recommendations

    After hearing the webinar I wanted to offer some practical recommendations from the talk and some of my own. Firstly, I want to stress that this is by no means an easy task. Especially, if you are working alone without a team of sports scientists. I want to start off by saying first;

    • Do the best you can.
    • Figure out what is important to measure and how it will affect your decision making, for example, peak height and weight velocity in youth athletes.
    • Build buy-in by educating coaches and athletes as to why you are collecting data.
    • The higher the level of the athlete, the more in depth the analysis.
    • Once you find out what you want to measure, find out the most cost effective way of doing this. There are a wide array of wearables that athletes can purchase which are fairly inexpensive. For example, Heart rate monitors for objective measurements.
    • Once you have the collection method for example HR monitoring, paint the picture by working out the intensity of matches and seeing how that compares to training for planning purposes. Are we wanting to work at or below match intensity?
    • Work with the technical coaches using your understanding of scientific underpinning of training and their knowledge of skill development to come up with an agreed monthly/yearly schedule.

    Keeping Athlete Shoulders Healthy

    With the initiation of a third lock down in the UK we thought it would be a great idea to engage our readers in some motivating posts to help keep you motivated.  We welcome back APA coach Konrad McKenzie with a weekly guest post.

    This lockdown 3.0 I have been fortunate to gain some more knowledge from leading practitioners in strength and conditioning & sport science. A couple of weeks ago I took part in a webinar with Chris McCleod and Ben Ashworth regarding shoulder health which I wanted to share with you. Those that know me will know I currently work in a Tennis Academy and have had previous work in Rugby and Swimming. So you can imagine this webinar was of interest to me.

    Inherently, the shoulder joint is quite unstable, due to bony structures and lax ligaments most of its stability is provided by the rotator cuff musculature. It is particularly important to increase the structural strength of the local and global musculature around the joint. This blog will cover, what I learnt on the webinar with some of my own additions, the following topics will be:

    • Local and global musculature of the shoulder
    • Glenohumeral joint Stability
    • Thoracic Mobility
    • Volume load and Shoulder health
    • Some exercises for your tool box

     

    Local and Global muscles of the shoulder

    As always, I wanted to introduce this topic by giving a brief overview of the anatomy of the shoulder. Frequently, when describing the anatomy of the body we use the terminologies “global” and “local”.

    Local musculature

    These are muscles located proximally to a joint and these muscles produce force to create stiffness around a joint during movement. Regarding the shoulder, local muscles include the supraspinatus, infraspinatus, subscapualris and teres minor. The aforementioned muscles form part of the rotator cuff complex and provide stability to the Glenohumeral joint during movement.

    Global muscles

    Global muscles are predominantly larger, superficial and responsible for initiating movement. These muscles attach from pelvis to rib cage and/or the upper extremities and are central to absorbing/transferring forces  from upper and lower extremities to the pelvis. Global muscles in the shoulder girdle region include the Trapezius complex, Deltoids, Latissimus dorsi, Levator Scapulae and Rhomboids.

    Detailing muscles in any part of the body is like peeling away layers of onion, so it is outside the scope of this blog to highlight every superficial and deep muscle tissue surrounding the shoulder.

    The Scapula and Glenohumeral joint stability

    The joint between the Humerus and the Scapular is known as the Glenohumeral joint. Typically injuries are sustained in the structures of the Glenohumeral joint. However, we must not dismiss the role of the scapular in maintaining healthy shoulder function. I particularly want to draw attention to the serratus anterior, which is interposed between the scapula and posterior Thorax. Studies have mentioned that the mobility of the serratus and subscapularis are vital for healthy shoulder function (Codman, 1934). Furthermore, the gliding, rotation & tilting of the Scapula is known as scapulathoracic gliding mechanisms. I would like to add that the scapula and subscapularis are not the only muscles of the scapula, muscles such as the upper trapezius, lower trapezius, Pectoralis minor work synergistically (force-couples) to position the scapula optimally.

    Normal function of the Scapula is important. Shoulder strength can increase by up to 24% with appropriate scapular stabilization (Kibler, 2006).

    Scapula Stability and Shoulder dysfunction

    Sub-optimal scapula control due to over-activity in the upper trapezius and pectoralis minor is common. We know (particularly in overhead sports) that upward rotation of the scapula is imperative. Typically impairment is seen in a protracted and inferiorly positioned scapula. Additionally, the aforementioned dysfunction can decrease upward rotation thus decreasing sub-acromial space (Kilber, 2016).

     

    Thoracic mobility (T-Spine)

    I wanted to include this section because I believe, like the serratus anterior, T-spine mobility is important for healthy function. The thoracic spine is made up of twelve vertebrae (T1-12) in the middle segment of the vertebral column. In the Thorax the ribs articulate with each vertebra at the vertebral bodies and the transverse processes (Stull, 2016). Each thoracic vertebra rotates approximately 3°, therefore research has suggested that the thoracic spine should be able to produce 30-35° of rotation (Neumann, 2010). Now, you may be asking how this relates to shoulder function.

    The thoracic spine is engineered in a way that it can move in all planes of movement (rotation, flexion/extension and lateral flexion). The NASM suggest that the thoracic spine can produce 20-25° of extension (While this is not true extension, due to natural curvature of the T-spine) it is pertinent to shoulder function.

    So why is the small amount of extension in the upper back vital for shoulder movement?

    Well, to move the arm into full shoulder flexion, this requires the T-spine to move into extension. During shoulder flexion the scapula rotates upwardly & posteriorly rotates on the rib cage. Now, it is said that if the T-spine lacks the ability to fully extend, the scapula is unable to posteriorly tilt as a result. If this is the case, the Glenohumeral joint is unable to get into full flexion then the risk of joint impingement increases.

     

    Volume load and shoulder health

    It is common knowledge within the sports performance world, that injury is multi-factorial. However, one powerful way to reduce risk is load management. Interestingly it was said in the webinar that training load spikes of > 60% significantly increases the chances of injury, loads of < 20% also incurred an injury risk outlining the need to neither overcook nor undercook athletes. Now, what’s even more interesting is that a robust shoulder girdle was more likely to withstand training spikes in between 20-60%. This highlighted the need to micro-dose athletes with shoulder strengthening work, especially when away in competition.

     

    Some exercises for your toolbox

    Now, I want to introduce you to some exercises you can use for your toolbox. Some of these exercises are nothing special when looking at them, but that’s what I liked about them. They are simple and effective but the intelligence comes from how and why we prescribe them. The webinar described the exercise selections as “Shapes”, which I found very useful. I will now share these with you.

     

    Shape 1 – Single arm “Statue of liberty”

    It was said that single arm work is best, around 120° relative to the trunk (angle slightly above head height). This reduces the potential pec dominance and increases serratus anterior activity when executing single arm exercises.  With this in mind exercises, such as Landmine presses, single arm planks with arm slightly in front of the head make great exercises for shoulder stability.

    Fig 1. Take a notice at the angle of the shoulder, relative to the trunk.

    Benefits:

    • Supports upward rotation and posterior tilt of the scapula, to open up space and offload the shoulder.
    • With regard to tennis this exercise supports the avoidance of a shoulder dominant shot and “leading” with the shoulder.

     

    Shape 2- “Y- shape”

    This was said to target the connection between the posterior shoulder and mid-back. Additionally, on an EMG this shape was said to produce high activity in the posterior cuff and mid-back stabilisers. Furthermore, it was said that many people struggle to access this position. In my experience this is has been evident.  A regression I have used is on the knees. This allows the athlete to feel the right positions. When doing this exercise it is advised to place the thumbs back to place the shoulder into external rotation and recruit the mid back musculature.

    Benefits:

    • Supports the overhead connection between the arm and body
    • Protects against leaving the arm behind the body by connecting scapula to the Thorax

     

    Shape 3- The lateral line

    Muscles in the lateral line include the Obliques and unilateral trunk musculature. Exercises that target the lateral line include side planks, Single arm weighted carries and ipsilateral resistance training. Ben Ashworth suggested that athletes displaying a “buckling” of the hip during a single leg squat could be attributed with a weaker lateral line.

     Benefits:

    • Supports serve and overhead actions, which requires high amounts of side bend force, deceleration coupled with lateral hip stability.
    • Provides a strong base to transfer force from the lower body into the arm and racket.

     

    Shape 4- “Long Lat”

    We need strong Lats for a healthy shoulder (Think about its origins and insertions). But, we also need Lats that can produce force through a full range of motion. In overhead sports, this is important due to the racket and arm over the shoulder without any force leakage.

    Benefits:

    • Optimising efficient mechanics
    • Producing and maintaining force with a long lever arm.

    This was a great webinar, I certainly learnt lots whilst supporting my own knowledge already. I hope this blog has been insightful and causes you to do some of your own research around the shoulder. Thanks to Ben Ashworth and Chris McCleod for their outstanding work!

    Supporting Female Athletes

    With the initiation of a third lock down in the UK we thought it would be a great idea to engage our readers in some motivating posts to help keep you motivated.  We welcome back APA coach Konrad McKenzie with a weekly guest post.

    Supporting Female Athletes

    This lockdown I have been fortunate to gain some more knowledge from leading practitioners in strength and conditioning & sport science. A few weeks ago I was enlightened by some great speakers at the “The Well HQ”. The topic was around female health and performance. This was pertinent to me, as I am a male coach who currently works with a large amount of female athletes. I wanted to share some insights from this talk to enhance the awareness around this topic. This blog will be a synopsis of the webinar but will also contain some of my experiences training young female athletes, which will hopefully create some provocative insights. The blog will contain the following topics:

    • Knowledge gaps
    • What we do know about training female athletes
    • Menstrual cycles and how it can affect performances
    • Potential Barriers to sport and engagement
    • Steps we could take to support female athletes better

     

    “80% of active women said they haven’t had enough education in relation to their body and how it affects their sport”- Dr Bella Smith.

    There is a great book the “female athlete handbook of sports medicine” which I encourage you all to read. This book is quite extensive so I will give a very brief summary on parts of chapter 1&2 that stood out to me.

    Female athlete triad

    The female athlete triad is defined as a spectrum of three interrelated medical conditions 1) energy availability, 2) menstrual health and 3) bone health (ACSM, 2007). These conditions range from optimal/healthy range to a pathological state of low energy availability, amenorrhea, eating disorders & osteoporosis. It is said that in order for female athletes not to suffer any components of the triad, it is paramount that they understand their energy needs and train and live in an environment which supports healthy energy availability.

    Non-contact ACL injuries

    Female athletes are reported to have higher risks of non-contact ACL injuries. Interestingly, the research is trying to determine whether ACL injury is a result of gross failure of the ACL in one episode or multiple episodes over time. However, valgus of the knee and change in upper body trunk mechanics tend to be high risk factors for this. Although the research is said to be transient and the best intervention is not yet identified, changes in dynamic loading, proprioceptive training and sound coaching go a long way in mitigating these risk factors. Training programs containing a healthy dose of strength, power, plyometric and neuromuscular training, seem to have promising results.

    From the Well HQ talk it was said that women are 4.5 times more likely to sustain an ACL injury. Although the skeletal structure and the anatomy of pelvis is non- modifiable, factors such as muscle imbalance, proprioception and landing mechanics can be trained.

    Knowledge gaps in coaching female athletes

     

    The aforementioned quote is alarming right? A high proportion of female athletes still to this day are not educated enough about their bodies. Why? It was suggested, that there may still be a reluctance to talk about it, due to feeling ashamed or embarrassed. Whilst this is perfectly understandable, the more we communicate about this the easier it will become.

    “Trust takes years to build, seconds to break and forever to repair”

    Gaining trust is vital for clear communication pathways especially about sensitive subjects so this quote is important to bear in mind. Furthermore, I would like to note that it is important not to take offence if a female athlete does not immediately open up to you about what she is experiencing, this is a delicate manner thus, it is important to guide her to someone she feels more comfortable talking too. Women, unlike men, appear to value the quality of a relationship as opposed to the quality of a coach, meaning you have to take the time to cultivate and nurture the relationships you have with your female athletes.

    In my experience, I had a young female athlete who was going through her first menstrual cycle, you can imagine this was very troubling and awkward for her to mention. So she just gave me a sign and then I took the hint, to adjust certain exercises for her. Now whilst this is not very “scientific” it lead the way for her to download an app, which allows me to see when she’s entering that phase.  A pretty huge breakthrough if you ask me. More on this in “Steps we could take” Section

    Lastly, the women at Well HQ gave another profound statistic. I was pretty shocked about this myself. As little as 4% of sports science research is done on women only. Moreover, they had mentioned that the 70% of research done on mixed groups fails to control for the changing physiology and psychology during the menstrual cycle.

    Performance and the menstrual cycle

    The team mentioned that a 28 day hormonal cycle can really affect a woman physically and emotionally. From a performance perspective an elite 1500m runner with a 4:03 minute time could, on the day before  (or on the same day of her period) run the same event in 4:15 minutes. That’s a colossal difference. Interestingly, determinants of performance such as VO2 max, running economy, strength and power are not significantly affected during a healthy cycle. However, how a woman feels emotionally and physically fluctuates as her hormones change. As a result, this challenges her ability to tap into peak performance.

    It is known that having a period is a healthy sign of bodily function and health. On the other hand, 30% of female athletes lose their cycle at some point. To give an illustration of how significant this is, lack of periods meant a promising runner did not produce enough oestrogen (An important hormone in the cycle which aids bone strength) and thus developed osteoporosis in her 20s.

    Interestingly, Oestrogen creates a great physiological environment for muscle growth and repair. So much, that strength gains in the first half of the cycle can improve by 15%.

     

    Potential Barriers to sport and engagement

    I wanted to share some barriers to sport and engagement which, perhaps, is overlooked by trainers, coaches or Teachers.

    Bras

    It was mentioned that 80% of female athletes had poorly fitting bras. Furthermore, ahead of the Tokyo Games 72% had reported pain in training as a result. A poorly fitting bra can have significant effect on performance by up to 4% which is large at the elite level, where margins are thin. On the engagement side it was said that 33% of women with a cup size of D or above say they don’t exercise because of their breast size

    Pelvic floor

    It is common knowledge that pelvic floor issues affect older and post-natal women. However this is not the only category of women it affects, it also affects athletes. Leaking urine during training and competition as a result of pelvic floor issues (even in women who have not had babies) is quite common in high impact sports such as trampoline, sprinting or basketball. Pelvic floor dysfunction is an understandable barrier to sport. Positively, this can be rectified by including gym based pelvic floor exercise.

    Steps we could take to support female athletes better

    I wanted to share some ideas in how we could support our female athletes better, this is not an exhaustive or very descriptive list however I wanted to create some discussion and more awareness around this area.

     

    Education

    With such a large amount coaches and females themselves not knowing their own bodies, the first stage is education. However, educating is nothing if we do not create a safe space for female athletes to speak out and share what they are going through.

     

    Monitoring the menstrual cycle

    There are many apps out there including Clue, Flo and Eve. Although collecting this data is sensitive it would be great if we got to a stage where we had this information on the female athletes we worked with and tailored workouts accordingly in every club or academy. For example, focusing on strength and reducing the volume in speed and plyometric training during certain stages of the menstrual cycle.

    Environment

    As alluded to in the first paragraph, creating a safe space also means creating an environment where there is no scarcity in items such as sanitary towels or menstrual cups as an example. If this is evident in academies then I believe this will positively add to female athletes being comfortable enough to share their feelings.

    Training

    I will not go into this in too much depth as there is a lot of great work out there. Conditioning programs will have to address the areas of proprioception, muscle imbalance and strength to serve the needs of the female athlete better. It may be, that we spend longer in phases that address these qualities and spend more time to focus on things like landing mechanics and single leg squatting.

    “Check, Challenge, Change”

    Pacey Performance Podcast REVIEW- Episode 331 Danny Lum

    This blog is a review of the Pacey Performance Podcast Episode 331 – Danny Lum

    Danny Lum

    Research Gate

    Background: 

    Danny Lum

    Danny is Head of Strength & Conditioning at the Singapore Sports Institute for seven years,and also currently doing a PhD with a research focus on Isometric Strength Training for Sports Performance.  Prior to that he was the Strength & Conditioning Officer for the Singapore Armed Forces so was dealing with Military Training.

    Danny completed his undergraduate degree at the University of Western Australia (UWA) prior to doing the role in the Military for two years.

     

    Discussion topics:

    What options have we got when it comes to Isometric testing?

    ”There are single joint testing options as well mainly using the biodex equipment for rotator cuff internal/external rotation of shoulder, knee flexion/extension.  We also have multi-joint isometric testing such as isometric squat, isometric mid-thigh pul (IMTP), isometric bench press and isometric prone bench pull.”

     

    Why would we go down that route in the first place with Isometric testing vs. something more dynamic?

    ”The information we can get from isometric testing includes not just the peak force, but also the rate of force development (RFD) and if we combine the data we get from the counter movement jump (CMJ), and IMTP for example, we can actually calculate the dynamic strength index, which I believe many coaches are using it as an indication of whether they should train their athlete more with plyometrics or with heavy strength training.

     

    Some of the advantages of isometric training is that it is much safer because there is no movement involved you don’t get injured that easily, and it’s pretty quick, 5-seconds and you’re done.  The disadvantage is you can’t really use it for exercise prescription, like a 1-RM strength test.

     

    Quite a lot of studies have shown the peak force and the RFD are significantly correlated to activities like sprinting, jumping and change of direction.  There are also studies that have looked at striking, throwing and recently we did a study with sprint Kayaking.  I want to think that isometric strength assessment data will have a high correlation with activities that has mainly concentric contractions like cycling and sprint Kayaking, but the relationship with dynamic activity that requires the stretch-shortening cycle with the eccentric and concentric phase might not be as great.

     

     

    If you look at the literature and take IMTP and isometric squat for example, the relationship you get from the peak force with CMJ range from R = 0.30-0.80 so the range is pretty huge.  There could be a lot of reasons for this; it could be because of the familiarization, different athletes with different training experience and different strength levels and also the time of the year and the training phase they are in.

     

    Another thing to look at is the joint position where the test is conducted.  So for example, if you look at the literature you will see that the isometric squat when tested at a 90 degree knee angle vs. 120 degree knee angle; the relationship between the isometric peak force obtained and CMJ jump height will be higher when the peak force was obtained at a 90 degree knee angle, and same for sprint performance.  What we can get from this, is that if you want to conduct the isometric strength test to see if there is any relationship with a certain activity, probably get the person to adopt a joint position whereby the concentric force is initiated at 90 degrees.  This makes sense because the CMJ is usually initiated from a position where the knee is at an angle of about 90 degrees.

     

    But there is something interesting- that works for squat, but IMTP doesn’t work that way!  You can see that a IMTP is usually conducted at a knee angle of around 130-140 degrees, yet the  magnitude of the correlation with the CMJ height is as high as that obtained for the isometric squat at 90 degrees!  This is something I personally do not understand!!”

     

    What is the dynamic strength index and why would coaches be interested in it/calculate it?

    ”First we collect the peak force from IMTP- theoretically that is the highest amount of force your lower limb can produce.  You can also obtain the peak force of the CMJ.  Then you can divide the peak force of the CMJ by the peak force of the IMTP

     

    Dynamic Strength Index = Peak Force IMTP / Peak Force CMJ

    The isometric peak force on an IMTP is the maximum amount of force you can produce and how much of this force can you translate into a dynamic movement.  The Dynamic strength index provides you with an indication, so I think if it is below 0.65 this indicates that your athlete might need a little more ballistic training like plyometrics.  But if the dynamic strength index is above 0.80 then the athlete probably needs more heavy strength training.”

     

    Isometric training as a training tool- what benefits are people going to get from isometric training?

    ”First of all, similar to the isometric testing, it is simple, the risk of injury is very low.  You can see that in most of the injury cases, injured athletes will start off with isometric training to get the muscles activated (even when they are in a cast).  The exercise physiologist would advise the patient to perform some form of isometric contractions.

     

    The disadvantage is that people believe that with isometric training you only gain strength in that specific joint angle that you train at, of course when you look at the literature, this is not true.
    It really depends on the joint angle.  If I position the knee angle at 90 degree vs. 150 degrees.  At 90 degrees my quadriceps will be stretched more compared to at 150 degrees.  So if I train my quadriceps at a knee angle at 90 degrees where it is stretched a little more then the strength gains will increase across a greater range of motion as compared to a quadriceps at a short length.  So based on literature, if you train your muscles at a longer length using isometric strength training, then the strength gain might range up to about 40 degree from the angle you train at.  But if say, you train at a short muscle length, which is about 150 degree knee angle, then the strength increment might range up to about 15 degree from the angle you train at.

    The adaptations from strength training are similar to dynamic strength training.  You still get increased neural firing, neural recruitment and hypertrophy of muscle.  One of the adaptations from isometric training that is superior to dynamic strength training is the increase in tendon stiffness.

     

    This has high implications on RFD, so with greater tendon stiffness the force transmission from the muscle can be more efficient and will improve force production and RFD.”

    When creating isometric exercises in some very sport specific positions what kind of creative process are you going through when thinking about integrating some of that into these sports?

    ”Two things.  First thing is I’m always looking where the concentric action is initiated, and second is the position which reflects the bio-mechanically most disadvantageous position, for example the sticking point of a squat.
    With a group of Kayakers I replaced two sets of squats, two sets of bench press and two sets of bench pull with the isometric version of it, and the joint position they adopted was initiated from a similar place where the pull phase of the Kayak stroke was initiated.   What we found was that by replacing two sets with isometric training as compared to a normal traditional strength training programme, the Kayaker’s strength actually increased and performance on the ergometer 200m time trial was improved more than the group that only did the traditional strength training.
    What I believe is that by performing the isometric training at the position where the stroke was initiated this increased their ability to overcome the initial drag force they would face as they initiate the pull phase.

    I just completed one study with recreational runners where we compared plyometric and isometric training for endurance running performance.   For the isometric training they did a IMTP and an isometric plantar flexed ankle, so the ankle was in a neutral position when they did the plantar flexion.  What we found was that running economy was actually improved with the isometric group as compared to the plyometric group.  One possible reason is because recreational runners tend to avoid heavy strength training so with the isometric exercises as a stimulus that greatly improved their strength.  In that sense, people might ask if that would work with elite runners, and that would need to be researched.”

    When it comes to programming isometrics within the wider programme (annual plan) where does it fit?

    ”That is an interesting question, and honestly, I have no idea at this moment in time.  Personally what I do with my athletes is slot in the isometric training somewhere in the middle of a strength phase, because we know that if you have been training with the same method for a long period of time you tend to plateau.  So with the addition of the isometric training for a few weeks that might help to break the monotony and you might see some improvement.
    We don’t know at this point in time that if we continue to get the athlete to perform isometric training, will there be a long term benefit (because all my studies have only been 6 weeks long)?
    The next thing I do is as we get closer to important competitions I get my athletes to perform complex training, and I usually use the isometric exercise as the conditioning activity to induce the post activation potentiation (PAP) effect, before they move onto the ballistic exercise
    One reason is because they get to perform maximal contractions so that helps to maintain their maximal strength and because it’s an isometric movement we are reducing the risk of injury close to competition.”
    Is it possible to manipulate some of the variables within isometric training to target different physical qualities such as hypertrophy etc?
    ”When you look at the research you can categorize isometric training into two different methods- yielding and overcoming.

    Overcoming

    Overcoming- is the method I have been researching where you push maximally against something you can’t move.

    Yielding 

    The yielding or ”holding” method where you lift a weight that you can actually lift around 60% of your 1-RM, get to your sticking point and hold it there for about 10-seconds before you push it concentrically.
    When you look at the research on isometric strength training, in order to get maximal strength increases you want to be contracting as near to maximally voluntary contraction (MVC) as possible in a range of 80-100% MVC and each contraction you don’t want to be holding for too long, otherwise you might compromise the adaptation.
    When it comes to hypertrophy you want to perform the contraction at a lower intensity and sustain the contraction for a longer period of time, as long as 10-30 seconds in one go.  Recently, there is one study which showed that the inclusion of isometric training might be able to induce a stimulus similar to blood flow restriction training.  So when you are sustaining the isometric contraction you are actually constricting the blood flow.
    Another study by Brett Shaunfield showed that performing isometric contractions in between sets increased the hypertrophy training effect.  So during the hypertrophy phase one of the things you could do is perform a lighter load in the final set and doing a long duration isometric contraction at the sticking point to increase the hypertrophy effect.
    In terms of other variables, first we need to know what we want to achieve before we start talking manipulating the variables.  Variables we can manipulate include the joint position.  I mentioned earlier that if we train at a joint position that induces a longer muscle length your strength improvement will be greater throughout a greater range of motion.
    At different joint positions you might induce hypertrophy at different parts of the muscle.
    So for example, if I was sustaining isometric contraction at a long muscle length most of the hypertrophy training effect might take place at the middle of the muscle belly (midsection).  If I perform it at a shorter muscle length, most of the hypertrophy might occur at the proximal or at the distal portion of the muscle, so these are things that people will need to consider.
    To increase maximal strength you will need to contract at a high percentage of MVC, and to increase RFD you will need to contract at a high contraction speed, so in sports performance you should always try and contract explosively because we are not just talking about how strong you are but we must also ensure the athlete can produce the force as quickly as possible.”
    Are there any gaps we are looking to plug in the research?
    ”Firstly there is training at long muscle length vs. multiple joint angles.  I mentioned that if you train at long muscle length the strength gains will be higher through a greater range of motion but if we train at multiple angles it might actually be more beneficial.  So if I compare 3 sets of bench press at 90 degrees vs. 1 set of 180 degree, one set at 90 degrees and one set at another angle we could compare multiple joint angles
    The other limitation of what we know is how long this beneficial effect can last?
    The other one is comparing the training effect of a yielding method (more similar to an eccentric method) to the overcoming method (more similar to a concentric method).  So get someone to push against 80% MVC and the other guy resisting against 80% MVC and comparing the adaptation.
    When doing this in training I would probably a certain number of sets so for example if I am going to get the person to do back squats 4 sets I might have them do two sets dynamic and two sets isometric.  The isometric is better at improving the strength at a specific joint angle, but when it comes to a full range of motion, isometric effect is still not as good as dynamic strength training, so I wouldn’t use isometric training as the main bout of the training but I would recommend the isometric training as a supplement to improve the force production at the sticking point or at the bio-mechanically disadvantageous position.
    In a complex setting, I would do the isometric exercise as the conditioning tool I would reduce the number of repetitions rather than trying to get them too fatigued.  But at the moment I haven’t done a study to identify the ideal number of sets.”
    Can you explain to us what we mean by quasi-isometrics (I know this is something Alex Natera has mentioned?
    ”Take the hamstring for example, which is a bi-articular muscle so when we are running and the hip is flexing the proximal portion of the hamstring is stretching but when the hip is flexing the knee will be flexing as well.  So the distal portion of the hamstring will be shortening.   So in that sense one portion is lengthening and the other portion is shortening, so that pretty much looks like an isometric contraction, and that is what is meant by a quasi isometric contraction.
    So if you take the hip thrust but with the knee in a slightly more extended knee position (around 150 degrees) with the shoulder on the floor, with the hip in the air, the hamstring closer to the knee will be trying to produce a concentric contraction so you can stay up.  But while the hip is heavy gravity will be pulling it down so the proximal portion will be in an eccentric contraction.  So the distal portion will be in the Push isometric contraction while the proximal portion of the hamstring will be performing a yielding contraction.”

    Top 5 Take Away Points:

     

    1. Isometric is a safe and effective way of performing strength testing and training.
    2. Dynamic strength index = Peak Force IMTP / Peak Force CMJ
    3. Importance of range of motion- strength gains will increase across a greater range of motion as compared to a quadriceps at a short length.
    4. Importance of tendon stiffness- one of the adaptations from isometric training that is superior to dynamic strength training is the increase in tendon stiffness.
    5. Considerations when choosing position- the place where the concentric action is initiated, and the position which reflects the bio-mechanically most disadvantageous position.

    How the ballistic quarter squat can support your athletic performance

    With the initiation of a third lock down in the UK we thought it would be a great idea to engage our readers in some motivating posts to help keep you motivated.  We welcome back APA coach Konrad McKenzie with a weekly guest post.

     

    During Lockdown, I have tasked myself with gaining an increased knowledge of anatomy and physiology so I have greater accuracy in my prescription of exercises. By this I mean, gaining a thorough understanding of how this particular exercise can positively affect performance. Today I wanted to talk about the ballistic quarter squat. Particularly, a concentrically focused variation. People looking at athletes performing this exercise and criticising the “lack of depth” need more context.

    So today, I wanted to talk about why I would like to include this exercise in my programme for field and court based sports. This blog will consist of the following sections.

    • Principle of specificity
    • What is the Ballistic quarter squat
    • Why is it relevant?
    • When to include the ballistic quarter squat

    Principle of specificity in Strength training

    I was digging up some old material and I found this book, which I plan to reread “Periodization Training for Sports” by Tudor Bompa. They say nothing is new, just repackaged so it seems prudent to go back over the old texts. I’ll briefly go over some of the components of specificity and give a brief summary of them. Specificity is of huge importance as the body adapts in specific ways to a recurring stress, see “SAID principle”. There is a reason you form callouses on your palm, not your face when participating in frequent weightlifting (I hope).

    SAID

    A common term used in the area of strength and conditioning is an acronym for “Specific adaptations to imposed demands” meaning that the body will make adaptations that will allow the body to get better at tolerating a specific form of stress that is placed upon it.  Some of the variables to consider when determining an exercise’s specificity to the sporting demands include:

    Joint range of movement

    This refers to the joint angles regularly displayed by athletes performing the sport. For example, a tennis player preparing to initiate movement from a ready position. Or a front row rugby union player pushing in a scrum.

    Bioenergetics

    This refers to the energy system demands of the game for example, a game of junior tennis is predominantly an aerobic based sport with intermittent bursts of anaerobic activity. Another example would be the short sprints with high demands on the anaerobic-alactic system. Understanding energy systems will help decipher the work to rest ratios of the sport you are working in. Check out my blog on the “demands of the game” for tennis performance.

    Planes of movement

    Body movements occur in different planes around different axis. The three planes that you are typically taught are the frontal, transverse and sagittal plane. Field and court based sports would typically move in all the planes mentioned. For example, when hitting a groundstroke in Tennis a player will be predominantly working in the transverse plane however, when moving forward for a volley or dropshot there may be more of an emphasis in the sagittal plane. This is quite reductionist and planes of motion in sport could be an article in itself.

    Muscle contraction (type and speed)

    This is interesting and most recent conversations in this lockdown period, have forced me to ask how a muscle is “behaving” during a specific activity. What is the contraction type? How fast and how hard does it contract? For example isometric activity of the glute maximus in the stance phase of sprinting.

    When constructing a needs analysis a coach would typically have these in mind when preparing a training programme. See my blog on Fundamentals underpinning a physical development strength program for the youth athlete.

     

    What is the Ballistic Quarter squat?

    Firstly, a ballistic method is a type of training where the athlete’s body (or object) is explosively accelerated throughout the entire movement. If we go back over our notes and look at Henneman’s size principle we know that motor units are recruited in a precise order according to their force output. It seems as though there is a superior activation of type two fibres with heavier loads as opposed to lighter ones (Henneman, 1965). Additionally, when exercises are performed in a ballistic manner they seem to have a superior potentiation effect compared to non-ballistic counterparts.

    The Ballistic quarter squat is a squat variation with a heavy concentric focus. The lifter is asked to concentrically propel the barbell vertically using upper and lower limb, from a quarter squat position, as shown in the picture below.

    Why is it relevant?

    The Ballistic quarter squat is an exercise that I have come across recently, what was interesting to me was the “Ballistic” element of this exercise and rate of force development required to perform this exercise well. High levels of Power is the result of work divided by time, or in simpler terms, applying the highest amount of force in the shortest amount of time, significant for most field or court-based sports.  With some more research I found that performing this exercise at around 90% of one repetition maximum had superior effects on sprint and vertical jump performances (Weiss, 2000).  Other studies have also advocated the integration of quarter squats in a conditioning program (Rhea et al, 2016).

    Possible reasons for this was again, the joint angle specificity but also the ability to overload the intensity at this joint angle. Highly trained athletes may squat 30-45% more in a partial range squat compared to a squat with full range.

    Whilst this blog is not going to compare the differences between the full depth squat and quarter squat variations (readers are encouraged to read this paper if interested in that) it enables us to understand the relevance of the ballistic quarter squat.

    1. Joint angles

    Although it is said that many explosive movements in sports are initiated from a knee angle of approximately 90° (Suchomel, et al 2015) these include sprinters in the blocks, wrestling NFL linemen etc, I would argue that knee joint angles shallower than this are also executed. Thus, if we remind ourselves of the laws of specificity, training explosive strength from these similar joint angle positions would be beneficial for performance.

    1. Propulsion

    In order to overcome the body’s resting inertia, athletes need to be strong. How strong, is a topic for another day. But, muscles of the lower body (Glutes, Calves and quadriceps) most forcefully extend to project the body forward. If you look closely at my first picture under “What is a ballistic quarter squat” you will see the athlete forcefully extending knee hip and ankle. This extension occurs with high levels of intent and speed, although a heavy ballistic squat may not be specific to the speed of contraction, it will certainly enhance the force potential of leg musculature.

    When to include the ballistic quarter squat

    If we tie in the joint angle specificity, the muscle contraction type/speed, motor unit activation from heavy loads and the bioenergetics of the movement, the ballistic quartet squat seems to have a place in my exercise inventory.

    Due to the reported benefits at performing this movement at 90% or 1RM it seems rational to include this in a power phase, more specifically a strength-speed phase of the annual plan.

    Are Banded Sidesteps Doing What We Think They Are Doing?

    With the initiation of a third lock down in the UK we thought it would be a great idea to engage our readers in some motivating posts to help keep you motivated.  We welcome back APA coach Konrad McKenzie with a weekly guest post.

    This Lockdown 3.0 I tasked myself with diving further into Anatomy to give me even more clarity as to what exercises I am doing, why I am doing them and how I can vary them to get the response I want. I quite like this personal auditing and I will be doing this more regularly.

    The exercise I want to discuss on today is the popular Glute Band Side Step, a popular exercise used to “activate” or “wake up” the Gluteal muscles. Whilst there is research supporting Gluteal Amnesia, your glutes simply do not switch off. Reciprocal inhibition (Sherrington’s law) teaches us that overactive muscles could cause a reflexive relaxation on opposing muscles. In this case the over activity in the hip flexor complex may cause underactivity in the Gluteal. Lastly, low levels of glute activation and coordination may lead to altered biomechanics and extra stress placed through the spine, as the hamstrings and lower back are asked to compensate in hip extension.

    The ”prehab guys” suggest that prolonged sitting may cause slight damage to the nerve supplying the glute however this is not significant enough to cause muscular atrophy in most cases. Moreover, your glutes do not simply turn off otherwise you would probably be a pile of human on the floor, due to the glutes’ role in keeping us bi-pedal humans upright.

     

    The role of the Glutes in Athletic performance

    The gluteals are the primary hip extensors, external rotators and abductors of the lower body. In athletic activities such as sprinting, jumping and throwing the glutes play a large role in hip extension. During sprinting it is said that the glutes play a vital role in hip extension velocity during acceleration and in the stance phase of sprinting.

    When performing exercises such as landing from a box on a single leg the hamstrings contract the hardest and the earliest but the Glute Medius performs a higher degree of muscular work in the frontal plane. Additionally, knee valgus seen in lower body functional tasks such as bilateral or unilateral squatting may give us an indication that the Glutes are under performing.

    The benefits of having strong gluteal muscles are now well established with more people more than ever hip thrusting, bridging or performing the glute banded sidewalks. But, is this exercise doing as much as we think it is doing? Is this an exercise being given, perhaps, too much of the limelight? Today I want to dive into this.

    Banded sidewalks and glute activation drills

    It is apparent that banded side step works the hip in abduction and external rotation. Not only does the band stress the stepping limb, it challenges the standing limb too, as the athlete is asked to perform a lateral walk. Some great research by Lewis et, 2018 has suggested that placing the band around the feet increases both Glute Med and Max activation

    Glute activation is quite a common theme in an athletes warm up, the idea is that the athlete spends part of the warm up performing, as an example, two sets of banded sidewalks for 15 repetitions to increase Gluteal activity, or in some case “wake up the glutes”. But, is this too simplistic? And does the side band walk have an increased performance outcome?

    Whilst, I take everything with a pinch of salt, the more I learn is that what’s occurring is a result of a pre-fatigue and whilst it may be great for an athlete to feel their glutes, I am not sure it helps with performance outcomes, such as fixing knee valgus. Some research even suggests that pre fatiguing muscles leads to muscle activation in the synergistic muscle groups as opposed to the specific muscle you are targeting!

    The aforementioned leads me onto the next topic post activation potentiation (PAP) which is a short term improvement in performance as a result of a conditioning exercise. For example, a countermovement jump (CMJ) and a back squat.

    A phenomenon by which the force exerted by a muscle is increased due to its previous contraction” (Robbins, 2005)

     The conditioning exercises is said to place the muscles in a “potentiated” or “Activated” state thus, increasing (in this case) CMJ performance. Whilst the research of this is quite mixed, heavy loads (> 80% of 1RM) appears to be more effective than using lighter loads. If we are talking about activation, then this is quite a contrast. Whilst I am not throwing the baby out the bath water my question is.

    “What assumptions are we making?”

    Ok so do we not do this exercise?

    Firstly, you will hear this in the strength and conditioning communities quite a bit. Context is king. There have been great research on side banded walks particularly in the rehab settings to help rewire neural pathways or to teach a young athlete muscle awareness.  I just do not expect a magical solution from this in athletic performance.

    Before I dive into specific exercises, I want to take you back to basics and suggest that simply getting your glutes strong, increasing the your hip mobility and stiffness in your core will go a long way in getting in enhancing performance outcomes from the Glutes and enhancing cross sectional area (size). Great exercises include Barbell hip Thrusts, high step ups and good old fashioned back squats, performed with good technique.

    Structural adaptation

    We know that in order to create structural adaptions we can:

    • Increase Cross sectional area
    • Increase muscle activation
    • Increase muscle- tendon stiffness

    The literature around PAP, forced me to think that high volume, low load was probably not adequate in the “activation” of these muscle groups for performance enhancement. So how could I alter what I do to potentiate these muscles? Here are some ideas (I would also love to hear yours)

    • Fewer repetitions
    • Higher intensity
    • Yielding Isometrics

    Whilst these are not revolutionary or specific exercises it gives something to think about, for example take the typical clamshell exercise pictured below

    There are ways that we could modify this, perhaps, by using a heavy plate loaded six second isometric or using a very heavy band that can only be pushed for 3-5 repetitions. With some of my full-time athletes I would typically use a heavier plate loaded isometric hold to “activate” the muscles of the glutes, which is progressed through time.

    On a final note, I want to stress that I am not anti-band sidewalks, I just think they need to be taken a bit more lightly for activation purposes. They certainly have their place in clinical rehab or as a teaching method, to feel the muscle but this comes down to your “why”.

    The Lower Limb and Why It Should Be Important to You

    With the initiation of a third lock down in the UK we thought it would be a great idea to engage our readers in some motivating posts to help keep you motivated.  We welcome back APA coach Konrad McKenzie with a weekly guest post.

     

    Hi guys,

    Today I wanted to talk about one person’s friend and another person’s enemy. The calf. The time where it gets to summer and you realise neglecting your calves all winter makes itself apparent in shorts. But, did you know that the calf plays a pivotal role in physical performance? I’m here to explain why.

    At APA we have been having some great discussions around the calves and I am excited to share some of this information with you. Before we dive into training the calf, I wanted to briefly talk about its anatomy, as it will allow the reader to understand what role it plays in sprinting. The two muscles that I want to focus on are the Gastrocnemius and the Soleus. Both muscles insert in to the Calcaneus via the Achilles tendon however what is interesting to highlight that the Soleus (mono-articular), unlike the Gastrocnemius (bi-articular), does not cross the knee joint.

     

    The Soleus explored further

    Whereas the gastrocnemius plays more of a propulsive role the Soleus (coming from the latin word “Solea”) plays an important role in stability during running.

    The Soleus will work hard to keep the tibia over the Calcaneus to prevent you from falling forwards, during this time forces up to eight times bodyweight can be tolerated. The Soleus is predominately made up of Type 1 Slow twitch fibres.

    Due to the higher proportion of type one fibres the Soleus is known as the “Workhorse” due to its high endurance capability and high importance in stabilisation.

     

    The Gastrocnemius explored further

    Whereas the Soleus plays more of a supportive role in Explosive activity the Gastrocnemius are able to provide a significant source of power in propulsion due to the higher proportion of type two fibres.

    “Our simulation reveals that the ankle plantarflexors are the primary contributors to both propulsion and support of the body mass center during late stance” – (Hamner et al, 2010)

    The Achilles tendon explored further

    Also known as the biological springs, tendons play a vital role in assisting muscle work by storing energy known as elastic strain energy. This allows the human movement system to go beyond its intrinsic muscle properties, once this energy is released. As a result this amplifies power output. It is important to note that “Amplification” does not necessarily mean adding energy to the system but rather its rapid release.

    I have always been fascinated by the “spring” in the Masai warrior, a real display if athleticism, the reader is encouraged to have a look at this on YouTube.

    What role does the high strength & stiffness in the calf complex in injury prevention?

     

    “Strengthen your calves, save your hips”

    With the lockdown upon us and many more people participating in running based activity it is useful to incorporate some exercises to help keep you robust. During running the Soleus works eccentrically to slow the forward movement of the shin, with the aim of reducing knee load. Additionally, having strong calves will help you move with biomechanical efficiency preventing problems further up the body particularly in the hip region.

    Give this a try

    Rather than perpetually stretching your calf muscles, have you ever thought they might be weak?

    If you haven’t got access to fancy force plate testing systems, try finding a bench or a step. Perform a straight legged, single leg calf raise till voluntary failure, how many repetitions did you get? Does your technique begin to breakdown before 20-25 repetitions? Then it may be time to add some calf strengthening to your routines.

    OK my Calves are weak what can I do about it?

    • Bodyweight to loaded progressions
    • Aim for 2-3 sessions a week
    • Aim for 3 sets of 12-15 repetitions

    Mastered this? Now let’s look at loaded progressions?

    The muscles of the calf complex are strong and to train them effectively, once they reach a certain level, will require significant amounts of load, to put this into perspective elite athletes will use 20% of their bodyweight of each leg for three sets of 20 repetitions. In some cases athletes will handle loads of 200% of bodyweight in an isometric contraction (3-5 second holds). Additionally, performing exercises, e.g calf raises, with a bent knee will bias the Soleus.

    What about plyometrics?

    You have performed a knee to wall test and you’ve determined you have ample range of movement. Does this mean you have bullet proof lower limbs? What if I told you that having too much flexibility without pre-requisite strength and stiffness could create joint instability? Thus risk of injury.

    When broken down into its parts. Running is a series of hops from one leg to another, therefore musculo-tendinous units need sufficient “spring” and pre-activation for propulsion and injury prevention.

    Once you have determined that your lower limb has suitable levels of strength and endurance it will be a great time to add in some plyometrics into your program. A good approach I like to use is extensive to intensive exercises. E.g pogo jumps progressing to activities that place greater demands on musculo-tendinous structures.

    Ultimately, nothing will eliminate the risk of injury entirely unless you stop playing sports entirely, but we can give our bodies the ability to at least tolerate the demands placed on the body by sporting activities. The lower limbs are often overlooked but once we understand a bit about their role and function in sports, their importance becomes apparent.

    Although simplified, as the human body is more complicated than we think, I hope this blog has been insightful and given you some things to think about and explore in further detail. I want to leave you with a quote from Albert Einstein

    “Make things as simple as possible, but not simpler”

    Pacey Performance Podcast REVIEW- Episode 298 PJ Vazel

    This blog is a review of the Pacey Performance Podcast Episode 298 – PJ Vazel

    PJ Vazel

    YouTube Channel

    Background: 

    PJ Vazel

    PJ started as a sports journalist for the IAAF and began coaching in 2004 in the same year, coaching sprinters from Nigeria, Greece and France, Switzerland and Senegal.  He has most recently been coaching in throwing at World championship and medal level since 2015 when he came back to France.

     

    Discussion topics:

     

    Where did that love of sports history come from?

    ”I like the search of origins.  From a coaching perspective I had some ideas but I was not sure how to implement them, I was searching for what had been done before so not to replicate the mistakes and to go faster.  I wanted to know how the technical and resistance training had evolved over the decades, including the rules and regulations.”

     

    How did you first get into coaching?

    ”I was asked to help a young sprinter find a coach.  I asked around and actually no one was willing to help him, so some people told me: ‘coach him, go ahead and start!

     

    Working with a young Nigerian sprinter he had never had a coach, and I had never had an athlete, so it worked very well.  He had no bad habits and we were discovering everything and eager to learn together.  He was very motivated as every race he had was a way of living for him.

     

    I was travelling with him and sleeping on the floor, but what I learned is that really you meet some athletes who have extra motivation and they are killers on the track and that’s the kind of people you are going to meet, and you have to prepare athletes for that!

     

    Fortunately a huge part of sports history is the history of training methods so I kind of learned by accident the methodology of training so I integrated it.  The most difficult thing was to gauge the volume of training and basically what I did was cut everything in half from what I was reading in the books.  I kind of felt what he needed and the connection with the athlete.  I needed to trust the athlete and observing him, listening to what he had to say because he had a lot of experience.  Athletes use their body once or twice a day as their main work tool, so they know more more and as coaches we have to listen more to them.”

     

    Do you think with your lack of experience you were more willing to listen to your athletes rather than thinking that you know best?

    ”Not really because we all start from scratch.  The funny thing with my coaching debut was that I was still not fluent in English at all, so I had nothing much to say to them in English.  I was just listening to them, and I think that was better because I think that as a young coach I thought I knew a lot.  I think that if I had started with a French athlete I would have told them everything I knew, which I think is the wrong approach.

     

    If I had something to say I was managing to tell them [in English] but the important thing I was saying was the only thing I was saying.

    Because I was a young coach, others were not afraid to tell me their secrets.  I remember going to every athlete/coach who made the final and asked, ‘are you doing weights, and if yes, what weights are you doing?’  I found that everyone who made the final were doing weights.  I then went back to my athlete who was the first out of the semi-final: ‘look you are the only one who is not doing weights, and you are the only one who has not made the final, so maybe we need to do something different next year.”

     

    How has the history of sprinting changed in the last twenty or so years?
    ”I believe that nothing much has changed in the last 20 years or so compared to perhaps the changes that took place in the earliest part of the 21st century and even up to after the war, where science and methods evolved every four years.  In the last 20 years high tech technology yes but the concepts have not evolved.

    Take ancient Greece, they weren’t very concerned about times and to record it because they didn’t have a way to measure it with accuracy.  It was only in the late 18th century when we started to do sprint races where we could time it which influenced a lot the training methods of the 19th and 20th century.
    Perhaps you could say there is more of a focus on High-intensity now, not only in sprinting but also in weight training and also in team sports.  But it is a throw back to what was done in the early 20th century when athletes started to specialise in certain events (before they were all round athletes in the 19th century) and the physique was not that specialised either where the same person could win the short sprints and the long sprints.  In the 20th century it was deemed that you were either born fast or for endurance, with certain psychological traits associated with those disciplines.  This lead to the idea that in order to get fast you just needed to sprint, and don’t go against your nature.  And I think we see this now, where you are told to sprint with high intensity and low volume, but that’s what they did back then in the early 20th century.

    If you look at the results you get from this [specific] approach, you improve very fast in what you are doing because you are mostly doing the same thing but you reach a plateau very soon and you get tired, and you don’t improve anymore and you may even regress.

    There are more efficient approaches utilising more general training in the winter because they could see they could improve over a longer time during winter and get ready for summer competitions.  Because if you only sprint fast, within a few weeks you will plateau.  This concept of variability was very well understood in the 1960s.  Maybe now we are very focused on top speed and power, and finding out the exact power output you need to train.”
    What about the introduction/use of strength training- what impact has weight training had on the sport? And did it go too far and perhaps become too important and now it has regressed?
    ”So in the 19th century athletes were lifting weights because they were also throwers, power lifters etc and doing all kinds of training.  When sprinters started to specialise there was this idea that you needed to be light and doing weights you would get big, so weights are wrong.
    Now you can still find sprinters doing weights just for conditioning using dumbbells throughout the centuries but what really changed was science tried to prove whether it was meaningful to lift weights or now, so in Eastern Europe a landmark study in 1946 was done, because everything even politics had to have a scientific justification.
    They did a study comparing athletes who did weights and athletes who didn’t do weights, and looked at who is improving the most in terms of results.  It was found that throwers and sprinters who added weights to their training had better results in competition in their main event.

    However what was interesting, and a point that was lost in this research over the years, was that yes you need to do weights but it should not be at the expense of amplitude and relaxation of movement.

    This advice got lost because when they started to quantify this type of training they noticed that the more you train the better the results, which is true.  It is an observation that you cannot deny.  But the experience of coaches in the field, showed them that there was a limit to this.  But far from being unified the research was full of contradiction and controversies and the articles back then showed a big battle between coaches and scientists who disagreed over how much weights to do!”
    Why has there been so much more focus on Maximum Power?
    ”If we think about weight training, they soon discovered that there was an optimal amount and they needed to improve maximum strength as well as speed so they started to record the bar speed, and jump height in the late 1950s as opposed to just the max squat strength (absolute strength).
    The only concept that was not really important for the coaches in the 1950s that was not important then but is important now is the concept of max power.  But back then the concept of variability of training meant that to improve your power you needed to improve your max strength and your speed-strength.  But in between just focusing on that max power doesn’t make sense because you need variability.

    Using a variation of power athletes in the 1950s were improving more than the athletes using the exact power of their specific event) which is the 7kg implement of the shot put.  Only using the implement is less efficient than changing.  Why? Because of variability.  You are improving your technique because of the feeling of the muscles, small variations makes you a better skilled athlete.  Also the best intensity is not always 100%- at 90-95% you can still work at a high enough intensity to be relevant to your nervous system but you can also do enough volume to get the repetition of practice needed.  If you train 100% every time, you are crushing your nervous system, you can’t train at enough volume and you lose your relaxation!
    Most elite athletes who have achieved their best throws will tell you, that it felt easy, and they felt they could have done more!”

    What do you think about some of Frans Bosch’s ideas?

    ”He presented a lot of interesting exercises when I listened to him present.  I think a lot of coaches focus more on the exercises rather than thinking about the philosophy and how to implement/progress them.
    With instagram you now have athletes who will say to their coach, ‘I want to do this exercise.’ Usually the exercise is too advanced for the athlete and you have to explain to the athlete that there is a progression.   I think that most of what Frans presents is far too difficult for the athletes, even elite athletes.  Many athletes are great compensators and have developed crazy skills that hide great weaknesses.  And those are the weaknesses you need to address, and sometimes those fancy and complicated exercises are not pointing the finger at the weak part of the chain.”

    Top 5 Take Away Points:

     

    1. Importance of variability- you can improve for longer without crushing your nervous system
    2. Listen to your athletes- Athletes use their body once or twice a day as their main work tool, so they know more more and as coaches we have to listen more to them.
    3. Earn the right! Many athletes are great compensators and have developed crazy skills that hide great weaknesses.  And those are the weaknesses you need to address, and sometimes those fancy and complicated exercises are not pointing the finger at the weak part of the chain
    4. Importance of relaxation- yes you need to do weights but it should not be at the expense of amplitude and relaxation of movement.
    5. Paradox of intensity- alternate days of high intensity with low intensity.

    With the initiation of a third lock down in the UK we thought it would be a great idea to engage our readers in some motivating posts to help keep you motivated.  We welcome back APA coach Konrad McKenzie with a weekly guest post.

     

    The wider the base the higher the peak, but do we spend enough time looking after our base?

    Hey guys,

    Konrad here and today I wanted to talk about foot health and strength, sometimes overlooked in the area of physical conditioning (I have been guilty of it myself). However, our feet are considered our suspension that plays a vital role in interaction with the ground.

     “Despite getting stronger, some athletes will still remain in “turtle mode” for reactive demands, while their peers train, get stronger, and are able to improve on the springy base they already have. What is this “springy base”? The answer is: the foot.” – Joel Smith

    Before we dive into training methods I wanted to lightly touch on the anatomy of the foot to give the reader appreciation of the foot’s complex and pivotal role in athletic movements. A detailed inspection of the foot will fall outside the scope of this blog, but I thought the readers would benefit from an overview. As the saying goes ‘you can’t shoot a canon from a canoe.’

    The forefoot

    The foot can be divided into three areas the forefoot, midfoot and rear foot. The forefoot is an important part of the foot as this includes the Toe (First Metatarsal). As you can see from the picture above this bone is quite thick and short compared to the other metatarsals. It is known as the shock absorber and plays a vital role in propulsion. Try sprinting after a long layoff, I guarantee that big toe will be sore!

    Midfoot

    As you may see from the picture the midfoot is made up of five irregularly shaped bones called the Tarsals. Clinically, these are called the Cuboid, Navicular and the Cuneiforms (medial, lateral & intermediate). These bones form the arch of the foot, which provides stability.

    Rear foot

    The rear foot is composed of the Talus and the Calcaneus, the Calcaneus is also known as the heel and the Talus sits on top of the Calcaneus and provides a pivoting joint for the ankle.

    Muscles and tendons of the foot

    We have briefly spoken about the bones in the foot. Now we will briefly look into the muscles that control the foot. The musculature that controls the foot originated in the lower leg. These are then attached to the foot via tendons and ligaments. These muscles include the Tibialis posterior, Tibialis Anterior, Peroneus Longus and Brevis, Extensors and Flexors. These muscles move, support and allow movement of the foot.

    Lastly, the tendons include the Achilles tendon (the largest and strongest tendon) which runs from the calf to the heel. This tendon is highly utilised in sprinting and plyometric activity. Other tendons include the posterior and anterior Tibial tendon. The reader is encouraged to explore the anatomical origins and insertions further.

    Thought this would be an engaging picture. Check out the stretch in the Achilles tendon in frames ‘B’ and ‘C’.

    You are now aware that our foot is a vital link between us and the ground. The foot’s ability to absorb many times our bodyweight, through activities such as jumping and sprinting highlight their importance in relation to health and physical training. Personally, I make sure that all my physical training programs contain exercises which focus around foot strength and stability.

    Ok, we get it its importance how do we train the feet better?

    I wanted to share some training ideas you could use to strengthen the feet. Some of these ideas will not be as complex as one may assume. These ideas presented will, hopefully, be practical enough that you can implement with minimal equipment and mental bandwidth!

    More barefoot work

    The beauty about this, is you can incorporate this method into your everyday training (provided it’s safe). Before we dive into this I want to quickly quote a highly respected Strength and conditioning coach Loren Landow, someone much smarter than me on this topic;

    “The problem when people start doing ‘barefoot’ work is that they go for the gusto! It’s not about sprinting in barefoot, it’s about doing these intrinsic movements (such as standing on two feet or one foot and rotating around your feet to feel the eversion/inversion etc) to get you a better foundational stability.  I may squat them and do lunges but I think people are getting a little too carried away doing all their locomotive drills barefoot.  Is the juice worth the squeeze for the risks/benefit?”

    Now, sometimes people are guilty of receiving thought provoking information and going to extremes, you can see this in ‘diets and training fads. However, small alterations in behaviours may elicit large pay offs. In this case, it may be worth doing some weight room and balancing activities barefooted to challenge stability and strength.

    Where possible, a trainee should try incorporating more barefoot training for two reasons. 1) Increasing intrinsic foot strength 2) Improve the sensory processing between the feet and the ground. You will sometimes hear coaches suggesting to “feel the ground” during activities such as weightlifting. Shoes may make it more difficult to attain this sensory awareness. Moreover, training barefoot in different environments could great superior adaptations whilst your system tries to find stability in chaos.

    Skipping

    Since starting work in Tennis, I was surrounded by youth athletes who could skip with prowess and flair! It was so refreshing that a relatively simple training tool was a piece of equipment in every athlete’s bag. Additionally, we get so lost in the complexities of training methodology that we forget about the brilliant basics. However I mentioned in a previous blog that those who understand principles can employ any method. What are we getting out of skipping? Repeated submaximal and stiff ground contacts. Not mentioning other benefits such as rhythm and aerobic fitness (Depending on how you implement it). You could even try doing this on a barefoot for the reasons alluded to in the previous paragraph.

    Intrinsic foot strengthening exercises

    Intrinsic foot strengthening may not be seen as the most glamourous exercises but important considering the time spent in shoes, socks and walking on even terrain. Additionally, as you delve further into the human body, you will appreciate the dynamic and complex interconnections. This blog post about back pain being relating to the big toe highlights this.

    “Due to cramped spaces and the inability of the joints to function in their natural range of motion, our brains lose the neurological connection to the muscles of our feet, causing compensations. Luckily, neuroplasticity (the ability for our brains to change the neural circuits to our bodies) dictates that it is possible to improve and even reverse chronic instability of the foot, and thus joint pathologies and pain.”

    – Arash Rex Maghsoodi

    The Prehab guys have some great content around foot strengthening, particularly around big toe movement, give some of their exercises a go. You can practice them in the shower!

    Overall, this an area I will explore further and I hope you will too.

    Many thanks for reading, hope you enjoyed it!
