Why the secret to getting results with children is having fun

Today’s blog comes from APA coach Patrick Waplington.  It is very relevant as I posted only a few weeks ago on the principles of training junior athletes in terms of hours.  This blog focuses on what to do during those hours of training.   I will start us of by giving an example of a programme for a typical 60 minute squad for our 12-16 years old athletes.  Then Paddy will give us some information about the work he has done with our slightly younger Junior Academy, 8-11 years old athletes.

Below is an example of what I call a complex session, because it basically covers a little bit of everything.  For a developmental level athlete you can still make great gains in all the biomotors even when they are trained at the same time.

APA Blog – The use of Games with Junior Athletes

Everyone loves a game! And this is something I have used to my advantage over the last year. A big part of my work with APA is working with the Junior Academy. This is a squad session that runs Monday – Friday and regularly has between 15 – 20 young athletes taking part. Whilst there is a ton of S&C literature, with plenty of advice for training programmes for youth athletes, it can be a completely different story when trying to implement this in the real world.

Check out the video below for an example of a ‘Game’ that could be used for Multi-directional Speed:

Ask under 12s to run a multi-directional speed drill whilst displaying the correct turning mechanics and they can lose interest before they’ve even started! Challenge them to compete against one another or in teams and suddenly they have a reason to perform well and want to. This is where the coach can use their creativity to put their own mark on the session. I use a lot of games to promote the athletic skills I am trying to develop. This immediately adds fun to the session and engages the participants. This “fun factor” is of huge significance and not often mentioned in the literature.

How about this challenge to work on ‘Strength’ in a fun competitive way?  Who can be the first pair to get up?

Manipulating the rules or scoring of the games to promote specific athletic skills is a fantastic way of keeping the fun element while still getting your coaching message across. I use various methods to do this, such as awarding bonus points or even all the points for displaying good technique, or changing the space or boundaries players have to work in. These methods start to create a level playing field for mixed ability groups, as you can raise the expectations or difficulty level for the more committed athletes while still challenging the others in the group.

I have a number of games I use to promote different athletic skills. I get the game started and observe, pull the group in and run some drills to work on a specific element relating it to the performance in the game, then get the game up and running again, hopefully with an improved performance.

Participants will feel like they’ve played games throughout, but the coach will see how they’ve improved athletic performance. By the end of the session the athletes will have had some of what they want and some of what they need. Getting this mix right is part of the art of coaching.

Why bread is bad for you!

This week I have been on my travels.  I went to watch the ATP Challenger Tennis at Surbiton where several APA athletes were competing.

Then today I was at the Elite Sport Performance Expo where I met a few cool people.  Not only did I find out about some of the latest technology innervations in the sports performance field I got a few free assessments done on myself that I might integrate into our athlete profiling at APA.  I did a sweat test with Precision Hydration, a body fat assessment with a bioelectrical impedance company, and a hip and shoulder joint assessment with Biomechanics Education.

 

My changes in body fat have been the inspiration for a few blogs over the years but my trip to the expo has inspired me to write another one. Click here, here and here for some of the previous nutrition posts. Today’s bodyfat measure showed me my body fat has been creeping back up to where I started when first approached Ultimate Performance.  It’s now 17% again so that was my kick start to get back towards 10%.

This post is also inspired by one of my pro athletes who coincidently asked me about whether bread is good for athletes to have.


What is bread?

  1. flour- a powder obtained by grinding grain, typically wheat, and used to make bread, cakes, and pastry.
  2. Bread is usually made from a wheatflour dough that is cultured with yeast, allowed to rise, and finally baked in an oven. Owing to its high levels of gluten (which give the dough sponginess and elasticity), common wheat (also known as bread wheat) is the most common grain used for the preparation of bread.

Some people have been eliminating foods from their diet that contain gluten in the belief that it is damaging their health.  For more information about this read here.

 

What is gluten?

  1. a mixture of two proteins present in cereal grains, especially wheat, which is responsible for the elastic texture of dough.
My take is that foods that contain gluten including bread (and pasta) are part of a normal healthy balanced diet.  However, I definitely support the principle of being strategic with your starches.  Bread can certainly be part of your diet, but just like any carbohydrate it’s about the timing of what type and when you eat it.

What do the experts say?

Dr. Mike Rousell has recommended to have around 60-80g (up to 100g in large athletes) per Starch meal on training days. These meals will take place at breakfast, during workout shake, and in two meals following the workout.  So you’re looking at recommendations of about 240g-400g on training days depending on size of athlete.

 

On non-training days he advises a starch meal at breakfast (60-80g) and five further non starch meals at all other times (20g) so around 180g per day on non-training days.

 

He also advises around 50g of protein per meal, eaten at each of the 6 meals in the day.

 

But don’t just count calories!!!!

 

If you use Apps like My Fitness Pal to count how many calories you eat but you don’t pay attention to what type or when you eat them you’re missing a big piece of the puzzle.  For a great blog on why ‘A Calorie is Not A Calorie’ click the link.  This blog talks about calorie counting but also when to have Carbohydrates.

 

What type of Carbohydrates are best?

 

There are two main types of Carbohydrates:

 

1. Whole grains (starches): also know as ‘complex carbohydrates:’

 

Include foods such as porridge oats, wheat based cereals, rice, pasta and potatoes and can be consumed when the demand for energy from the body is high.  They release their energy more slowly.

 

Whole grain

-A whole grain is a cereal grain that contains the germ, endosperm, and bran, in contrast to refined grains, which retain only the endosperm.(Wikipedia).  

 

Vegetables– are also a form of complex carbohydrates but can be eaten in abundance because they contain only around 26 calories/100g so should be eaten at lunch and dinner!

 

2. Simple carbohydrates: 

 

Simple carbohydrates are sugars. All simple carbohydrates are made of just one or two sugar molecules. They are the quickest source of energy, as they are very rapidly digested.  Think sports drinks, confectionery, cereal bars, and fruit.

 

Fruit– is technically a simple carbohydrate — but it also contains fibre, vitamins and antioxidants. The fibre in fruit helps slow the digestion of carbs, which is why your blood sugar doesn’t spike as much after eating fibre-filled fruit like it does when you gulp down a fizzy drink or a chocolate bar.

 

As you will see below you can eat all of the different types of carbohydrates but it’s about eating them at the right time!

 

When should you eat Carbohydrates?

 

Most experts now agree that nutrient timing places a big role in weight management.  It is generally agreed that the best time to eat carbohydrates is:

 

1.  Breakfast- complex (60-80g) 

2.  Snacks- simple (fruit) 

3.  Workout-simple (50g workout shake)

4.  Post-workout Meal-simple (within 30 minutes) and complex (60-80g within 2 hours) 

 

Training days:

 

So on training days you will have complex carbohydrates at breakfast and in one or two meals following your workout.

 

Non-training days:

 

On non-training days you just have complex carbohydrates for breakfast!!

The rest of the day can be fruit for a snack and vegetables at lunch and dinner!!

 

Food Types Medium

 

The key take away message is to make sure you are strict with your intake of complex carbohydrates and simple sugars on non-training days!!!!!  It really is the key to stay lean over Christmas.  If you want to pig out a bit more on Carbohydrates then make sure you do some training before your Christmas dinner.

So going back to the pro athlete’s question about bread, he would be fine to have it at breakfast on a training day or a non-training day.  But on a training day you could also have it as a post workout meal. Don’t do what I sometimes get lazy doing and always have sandwiches at lunch!!

Why our tennis players aren’t using Olympic lifts

Why our tennis players aren’t using Olympic lifts

This week the athletes I spend the majority of my time coaching came back from half-term and were due to be progressing into the final phase of their peak performance training plan.  They were supposed to be realising the training effects of their strength and power phases by working under conditions of fatigue- what I refer to at APA as Power endurance.  For me this is really the goal of where I want to get to- at least in this population of Tennis players.  And my intention was to use Olympic lifts for timed reps to achieve this.

 

Disclaimer alert:  To quote Eric Cressey from his excellent book, The Ultimate Off-season Training Manual, ”There is a noteworthy difference between “conditioning” sessions and “speed” training.  The former serves only to enhance short-term metabolic preparedness, while the latter seeks to effect favourable changes in the powerful neuromuscular system that governs performance via long term adaptations.”

 

Peak Performance Body Pyramid

 

So this phase was really more focused on end stage conditioning to enhance short-term metabolic preparedness closer to the important tournament block.  In my mind we had already got some good neuromuscular adaptations and they had earnt the right to endure those qualities under fatigue. However, with Eric’s words of caution about just doing stuff to get children tired rather than getting them moving well, I had to stop right in my tracks and question whether Olympic lifts were a good fit for the athletes in front of me.  Were they moving well?

 

I decided they weren’t and here are my reasons for why they were going to stop doing Olympic weight lifting for power endurance for the current block.

 

I’m the biggest fan of Olympic lifts and I have written several blogs (here and here) about power development and why I thing the derivatives of the Clean and Snatch are the king of power development exercises.

 

Suffice it to say Olympic weightlifting is very popular as a tool to promote power.  Why is this so? Because Elite level Olympic weightlifters are capable of snatching over 150 kg and can clean and jerk over 200 kg. It is impossible to perform Olympic weightlifting movements at a slow speed.  So you get a great combination of strength and speed. You get the same amount of power generated as with a plyometric bodyweight jump, but you also get strong at the same time!

 

The most powerful of all movements is the Olympic weightlifting action of the second pull of a Clean, peaking at 55.8 Watts/kg (Garhammer, J. J. Strength and Cond.Res. 7(2): 76-89. 1993).

 

But………………. common sense tells me that if you can’t perform a movement pattern efficiently then you can’t load it and you certainly can’t perform it under fatigue.  The simple truth was my athletes were getting too tight around their thoracic spine and shoulder internal range of motion, and couldn’t pull with the proper movement mechanics.  This was a relatively recent development where we were probably putting too much responsibility on the athletes themselves to take care of their stretching and mobility needs.  This on top of the fact their tennis training volumes were pretty high putting a lot of stress on the anterior chain.  So while they were okay for a few reps in our power phase I felt I was pushing the envelope in this phase as they seemed to be getting tighter around their backs and shoulders.

 

Olympic Lifts – Considerations for Tennis Players

 

With respect to the Olympic lifts, I know Eric Cressey is not comfortable with the amount of forces the snatch puts on the ulnar collateral ligament, which takes a ton of stress during the valgus-extension overload cycle that dramatically changes the physical shape of most pitchers’ elbow joints.  I’m not so sure the tennis elbow is subjected to quite the same elbow stresses and I actually like dumbbell power snatches for tennis players as I think the freedom of movement afforded by the dumbbell automatically reduces the amount of load you can lift.

 

However all the research suggests that virtually all baseball players have some degree of labral fraying (and I’d imagine it’s similar for tennis players). The labrum deepens the shoulder “socket” to mechanically provide stability in a joint that is designed for mobility. Without optimal labral function, going to the extreme demands of stability – overhead movements – is not ideal, especially under load.  So I would still be cautious with how much Snatch work you do with tennis players.

 

The catch on the clean isn’t something to which I’m going to subject to valuable wrists and hands that go through some serious abuse with every ground stroke although I see no problem with high pull variations, though, unless the athlete is getting a bit tight around the traps.

 

For this reason I thought about keeping the mid thigh clean pull in but even then I just thought it was working to amplify an over dominant front side posture and I wanted to give the upper traps and anterior deltoids a break.

 

 

Topped off by the fact that these teenagers were also in class every day and can never get off their phones and tablets, I just made the decision we needed to make some changes for this block.

 bad posture

Here was my solution:

 

My inspiration was to go back to the basics and look for other ways I could get some power endurance using patterns that wouldn’t require as much upper body mobility.   So my key aim was to get more mobility around the thoracic and hip on my recovery days and go after the posterior chain on the power endurance days using kettlebells.

 

1.  Focus on Hip mobility and thoracic mobility

 

I suggest you check out this article on how to improve rotation while protecting your lower back.  Also check out www.redefiningstrength.com for some excellent blog posts that I used to create my Supplementary myofascial release and mobility drills for foot and leg, knees, lower back and hips, and neck.

 

Also check out this nice hip flow series which is a bit more dynamic and can be used to warm-up for the kettbell workout.

 

 

2. Focus on posterior chain hip power using kettlebells

 

 

I suggest you pay attention to the cues here as otherwise you can end up doing something like this.  I am not a fan of doing what looks to me more like a squat swing with a lot of focus on the arms.  This would just be like throwing the baby out with the bath water and replacing one exercise (Olympic weight lifting) that aggrevates anterior shoulder region with another.

How much should junior athletes train?

I recently received a nice email from one of the coaches I taught on the 1st4sport Level 2 Certificate in Strength & Conditioning so I thought I would answer it as a blog post.  His questions are all about programming for junior athletes.

 

1.  I still have a few issues on creating a valid program for someone who trains everyday (couple of hours/day). If you have any suggestion, I would be happy to hear them.
I also have another issue, I am training the girls to have them ready for their Hockey, Netball and tennis season. The issues I have are:
2.  It’s often the same girls in each sport (meaning only a few of them are in netball and not in tennis and/or hockey) so there is no rest for them other than school holidays. I found that a lot of them are burnt out by May, June
3.  The school does Hockey S&C when the hockey season starts (in September just after the summer holiday, the girls are not physically ready after the holiday yet they start straight away playing matches) then S&C for netball when the netball season starts and S&C tennis when tennis starts. Do you think I should prepare them before, allowing them to be ready rather than trying to do injury prevention all the time?
So there are really three questions here and all of them could be a Blog post in their own right.  Let’s start with the first one.
How do you create a valid program for someone who trains everyday (couple of hours/day)?
The first question is open ended but I can ascertain from the context of his follow up questions that we are talking about ‘sport scholars,’ the gifted and talented group of teenagers that usually get picked to play in multiple sports. They usually have at least one sport going on each day and will typically be asked to compete at the weekend for their school, club or maybe even county/region or country!
On the plus side they are ‘training’ every day, so this means you might not be restricted to just one or two training sessions in a week like you might have with an amateur football club for example. They are also playing multiple sports- which is a good thing, and we’ll talk about that later.
But it depends on what you mean by ‘training.’  Are we talking about practising their sport 2 hours per day or are we talking about time set aside for physical training, or a combination of both?
As I don’t know the answer to this I am going to assume for the purposes of this discussion that we mean sports practice for 2 hours every day. So then the next questions you have to ask yourself are:
a. How much total training is appropriate for my athlete per week?
b. How should you divide the total training for this age group- what is the right blend of sports practice and strength & conditioning work?
This comes down to how you slice the pie!

 

 

I have included a table below which is based on my interpretation of guidelines for Tennis players given to me by the Lawn Tennis Association (LTA) in 2013.  I’ve put a column ‘old’ and ‘new’ for comparison. The old column represents the previous guidelines I had from the LTA.

 

 

Now I appreciate there is a lot of information in this Table.  But to help us focus on the most important information, narrow your focus to the Tennis column and look at the recommended Tennis hours in the ‘new’ column for the age range 12 years up to 16 years (I have selected this age group as our sports scholars will almost certainly stay in education in some form during this period). At 12 years old we are talking about a range of 9-12 hours per week of Tennis.  At 16 years old the range is 15-18 hours.
This is a critical period in a young athlete’s development.  We need to ramp up the training load- no question- but there is a point of diminished returns where you can tip the scales towards over training and a one way ticket to the physio’s room.

What does the research say?

 

 

 

 

 

 

 

 

This research confirms for us a couple of principles of training for young athletes

 

1. Don’t specialise too soon– More highly specialised participation in sports [from an earlier age] may be a risk for development of injury for young athletes
2. Play other sports at a younger age– players who competed in three sports aged 11, 13 and 15 were significantly more likely to play National level compared with club standard between the ages of 16 and 18 than those who practised in only one sport.
So a ‘valid’ programme for me for a young athlete would respect the ratios in the Table above and not exceed the upper limits of Tennis training.  Instead make sure the athlete is playing other sports and doing a healthy amount of Strength & Conditioning.
 I ‘generally’ recommend doing a maximum of 16 hours Tennis per week until aged 16.

 

 

The problem of some tennis parents (and coaches) is that they have never read any Sports Science recommendations. My personal opinion is if a junior tennis player has talent, then 15 hours a week tennis training + fitness and tournaments is more than enough for his/her development. If a tennis player does not have enough talent to play on the pro level, why destroy the young athlete’s health with 30 hours of training a week?

 

 

What about the multi-sport athlete?

 

I am all for playing several sports but there does reach a point when an athlete who truly wants to excel in one sport needs to start to specialise.  The 12-16 year old age range I previously spoke about is where I feel the balance needs to start to shift towards one main sport- training as much as 85% in that sport.  So I would need to ascertain from the coach what age group of athletes he is coaching; if the girls are 8-11 years old (pre-puberty for argument sake) then being a multi-sport athlete strikes me as a good thing.

 

 

Regarding the coach’s questions 2 and 3 it seems like the girls are not playing all three sports at the same time.  The sport changes with the time of year.  For the recreational athlete, or even a sport scholar, I think this is a good thing in principle- provided they are a bit younger.  If they are older and truly want to excel at one sport though, I wouldn’t be chopping and changing sports throughout the year.

 

 

As the coach says, the main downside of being involved in several sports however, is the potential to be able to practice all year round!  You never get to switch off and you could burn out!

 

 

 

 

Normally you would expect the athlete to go through a periodised plan which includes work, rest and play!!! In an ideal scenario you would work hard in your training phase, then go out and compete and then have a rest.  Most professional sports calendars have an off-season where athletes can spend a few weeks re-charging their batteries before they hit their training again.

 

If the girls are to get through the year unphased then there does need to be a planned rest period provided for the girls between the sports of Tennis, Netball and Hockey.  This is something the S&C coach will need to educate the Director of Sport on and explain why the girls are in danger of getting injured if they don’t get some rest after the competition phase of one sport and the start of the next.

Should juniors get ready for their sport by training in the summer holidays?

 

The final point regarding question 3 is a good topic to discuss.  If there is opportunity to practice/compete in a sport all year round when do you exactly prepare to play that sport?
In Tennis the pros have an off-season across late November to the start of January (around 6 weeks). Junior Tennis players are supposed to have an off-season of sorts in the summer holidays (around 5-6 weeks).  However, given the need to stay in school during term-time this is actually the preferred time for juniors to get stuck into some uninterrupted competition.
My solution is to make September and January emphasise S&C for a few weeks of each of those months. I am not a fan of putting the rackets down and only doing physical training.  However, what I will typically do is encourage the young athletes to do a few weeks of light training in early September, to give them time to rest after a summer of competing.  Then we will go for it for 3-4 weeks of higher training loads biased towards S&C.  We will do the same in January where we know they will have had a little bit lighter training over Christmas so we can build up to a few higher training loads in late January.
If the young athlete isn’t doing Tennis, cricket, or any other summer sport then absolutely plan for some S&C training to give you a head start to the year in September.  Just remember to plan in cycles of WORK + REST + PLAY!!!!!!!!
Hope that helps!
Using mean bar velocity to predict 1RM

Using mean bar velocity to predict 1RM

If you read my post last week you will notice I am going to start measuring the Reactive Strength Index (RSI) during a 30cm drop jump as part of the weekly monitoring with APA athletes.  I believe it will be more sensitive than using a standing vertical jump for this specific purpose.

I have also been looking at the use of the Gym Aware linear transducer for monitoring bar speed and the different applications for training.  The inspiration for this blog is based on sections I have been reading in a round table discussion- Freelap USA Round table: Velocity based training: for the Full article click HERE

 

I have summarised some key points below which I hope will help you decide on whether measuring bar speed is for you:

 

BRYAN MANN:

Training: % 1RM vs Bar Velocity:

If you asked what % of 1RM should you be training at to develop strength-speed, people would tell you around 50-65% or maybe even 70%. But if you tell them a velocity range they look at you like you’re crazy.

If we know we want to develop strength speed, we are looking at 0.75-1.0m/s (40-65ish% of 1RM); for accelerative strength 0.5-0.75m/s (around 65 to 80ish% 1RM); for absolute strength, under 0.5m/s (85-100%). Simply using velocities that correspond to the % of 1RM desired allows you to be right on the load you are utilizing, rather than hoping to be lucky that it was correct on any given day.

MLADEN JOVANOVIĆ:

1-RM Squat Prediction 

Long story short, one needs to know each lifter’s MVT (or minimal velocity threshold, a fancier term than velocity at 1RM) for every lift (or use generalized velocities—they can be pretty stable across different lifting abilities). Bench press tends to be 0.15 m/s (mean velocity) and squat around 0.3 m/s (mean velocity). One can then proceed by performing at least 3 warm-up sets with increasing weights (hopefully covering a range of at least 0.5 m/s) performed with maximal effort. Using simple linear regression, one can estimate weight at MVT. This can be 40%, 60% and 80% or 1RM. This can give one a quick estimation of 1RM (i.e. daily 1RM) that could be tracked over the duration of the training block and used to make adjustments if needed, or to basically see how the athlete is reacting to the training (if the goal is to increase 1RM).

Having heard what Mladen had to say above I decided to do an experiment of my own having read a few of his articles on hiscomplimentary training website.

Example: Pro Tennis player

Here is the example of a predicted 1RM test for a pro Tennis player I work with.  It’s not the best example and I’ll explain why but it gives you an example of the protocol.

The issue we had with my experiment was that we were ‘in-season’ and doing this between two important tournaments.  We hadn’t done a 1-RM recently and given he hadn’t been in a training block for a while we conservatively estimated his current 1-RM at 160kg.  This was because his previous pre-season 1-RM was 180kg.  Therefore we calculated his 3 warm-up sets with increasing weights (as suggested by Mladen) as 55, 65, 75 and 85% of 160kg.  The better solution is to have a more recent 1-RM to base your warm-up sets on. But as we only had a few days training I didn’t want to risk overloading him so I just guessed he would be around 160kg.

For those of you like me who are not mathematically minded I have rearranged the linear regression equation you can get in excel.  If you know the value of Y (0.3 m/s) which is the bar speed at 1-RM you can insert this value into the equation:

0.3- 1.2847 / -0.0055 = 179kg

As you can see I was able to predict that the athlete’s 1-RM was 179kg.  I was therefore able to track his 1-RM without actually having to get him to do it!!!!

 

One thing I would say is to make this assessment valid and reliable Mladen recommended doing 3 reps at each of the warm-up set loads.  He also recommended holding the position at the bottom of the squat for 1-second before lifting back up.  This may need some practice to orientate the athletes with this especially at the lower loads where the temptation is to move the bar much faster.

1-RM Power Clean Prediction Example

I have also wrote a blog previously about the application of using the clean pull to predict the 1-RM for a Power Clean.  J Strength Cond Res 26(5): 1208–1214, 2012.  For the full blog post click HERE

Findings:

  • peak power occurred in mid thigh clean pull at a load of 40% 1RM of Power clean
  • this corresponds to a bar velocity of 1.65 m/s

What I found interesting was that the bar velocity which corresponded to 1RM for the power clean was 1.25 m/s so you could load up the clean pull until you get to 1/25m/s and this would give you an idea of their power clean load.

midthigh clean pull bar velocity

The final section below discusses some further considerations when selecting exercises that are appropriate for training and testing power.

DAN BAKER:

Difference between a Strength exercise and a Power exercise:

Despite the same sort of % 1RM (sets working from about 70 to 80% 1RM), the mean velocities are much different. For the snatch push press, the velocities are around 0.8 to over 1 m/s. For the heavy squats, 0.3 to 0 .5 m/s. For the snatch push presses, the velocities remain fairly stable, despite the increase in resistance for each set. For the squat there is a decrease in velocity with increased resistance.

Strength exercises have a deceleration phase at the end of range when resistances are low (< 50% 1RM)= to avoid stressing the tendons and joints. On major strength exercises like squats, bench presses, and deadlifts, with resistances below 50% 1RM, more than half the ROM is spent in deceleration, making them less than ideal for power training even though at this low level of resistance the velocity may be high. The length of the deceleration phase decreases as resistances go above 65% 1RM. By 85-90%, there is no real deceleration phase, but the velocities are so low at this level of resistance that they cannot be classified as power exercises. So using light resistances below 50% 1RM in traditional strength exercises to develop power is often counterproductive as it is training the body to decelerate for much of the ROM, rather than continuing to accelerate.

So we do strength exercises with heavy resistances to develop force/strength, and power exercises with the appropriate resistance to train the body to use force with high velocity until the end of range. If you want to use “strength exercises” to develop power, you need to use resistances of 50-70% 1RM. Something to dampen the ferocity of a rapid lockout (such as bands and chains) also helps.

In addition, there are two measures of velocity and power—the mean or average of the entire range of (concentric) movement, and the peak, which represents the highest velocity in the shortest measuring time (say 5 millisecs). So there will be a difference between the two measures. When someone is doing a lot of end-range deceleration (because they may be trying to lift 30-40% 1RM in a bench press explosively), there will be a marked difference between the two figures as the body has to severely decelerate the lock-out to protect the joints. In Olympic lifts, which are virtually full ROM power exercises, there should not be a huge difference. If there is a more marked difference for one athlete compared to others, it suggests that they are decelerating near the end of ROM.

Why would they? Because they have mobility or technique problems and the body inherently knows not to continue accelerating (or at least, lifting with high velocity) until catch or lock-out. It may be dangerous to the involved joints, tendons, etc. So there may be a high peak velocity, but the body will slow down the speed to avoid dealing with high force and high velocity at a vulnerable end of ROM in athletes with mobility/injury concerns.

This may suggest that you don’t perform the full versions of the Olympic lifts (or power versions) with athletes who have mobility problems. You may be better off performing a variation (for example, clean power shrug jump instead of power/hang clean).

More than 20 years ago, Greg Wilson called this point—where mean power is highest—the “optimal power load.” It is different for every exercise and there is also individual variation. Some of my published research looks at bench press throws in a Smith machine by professional rugby league players. That “optimal power” (mean power of the entire concentric range) was 55% 1RM for weaker blokes (about 125 kg 1RM), 50% 1RM for the across- the-board normal blokes (about 140 kg 1RM), and 45% 1RM for the strongest blokes (about 150 kg+ 1RM).

Counter movement jump or Depth Jump- which is better?

For as long as I can remember I have used the standing vertical jump (SVJ) with an arm swing and a squat jump without an arm swing to measure power.  I use the SVJ as a measure of performance first and as a measure of fatigue second.

However, I have always doubted the usefulness of the vertical jump score as a measure of physical preparedness from the point of view of neural fatigue. I have reconsidered some research and also found some new information.  Below is some of my research.

The first part is based on experimental research conducted by Dave Hamilton, who presented his work with the Great Britain women’s hockey team in the three years of preparation for London 2012, at the UKSCA Conference.

The second part are some snippets of interviews that were conducted by Freelap USA during a round table on ‘Velocity Based training.’

Before we get into the findings it will be useful to clarify a few terms.  For ease of understanding I will clarify the difference between a depth jump and a drop jump.

Depth jump vs. Drop Jump

In the use of Drop Jumps, there are some problematic issues. The first issue regards the danger of Drop Jump for the leg joints, especially if performed from a high drop height. In fact, the important condition for efficient recoil of the elastic energy is the muscle’s stiffness during the amortization phase. In order to assure this condition, Drop Jump should be performed with low level of leg flexion at the end of ground contact phase. However, if the athlete “drives as a stake” into the ground, with the straight legs, the ground impact is too hard for his leg joints. This opinion has been confirmed by many researchers (for example, by B.U. Newton, W.B. Young, W.J. Kraemer and C. Byrne, 2001)

To avoid the danger of sharp heel impact, it has been suggested to use Drop Jumps only with low drop heights of 20–40 cm (Bobbert et al., 1987; Lees & Fahmi, 1994). The problem is that the use of 30cm drop height is ineffective at increasing the rebound height: it could assure only decreasing ground contact duration (W.Taube et al., 2011).

Taken from Jump Training 101- Dr Natalia Verkhoshansky

I’ve selected the video below to stress the fact that there needs to be a certain level of athleticism required to safely execute a drop jump.  The high levels of eccentric loading could cause significant stress to the knee joint if not adequately prepared.  Note the knee valgus present.

Part 1:

Dave Hamilton-Drop jumps- Reactive Strength Index (RSI)- DJ-RSI

Dave spent the first year of his role understanding the demands of the full-time hockey programme.  In his second year he focused on Monitoring:

His previous research with soccer players had shown that the counter movement jump (same as SVJ but without use of arm swing) didn’t show promise as a sensitive indicator of neural fatigue as indicated in the figure below.

Performance in the CMJ actually increased across six games.  Several other researchers have supported this.

 

Use of the Drop jump with calculation the RSI showed more promise because as the Figure below highlights, his research showed there was a significant drop off between pre- and post-game scores.

My conclusion: I have concluded that a drop jump from 30cm will be a more sensitive marker of neural fatigue than a standing vertical jump

Part 2:

Freelap USA Round table: Velocity based training: for the Full article click HERE

Bryan Mann:

While the vertical jump used to be the gold standard for monitoring, it really isn’t any longer as it isn’t sensitive enough. Many things can confound the results. Using technology, we can look at multiple factors that go into the jump.

A podcast with Carl Valle—who is also on this roundtable—mentioned using 40kg as the load for the jumps. You are getting weekly longitudinal data and a small training effect. Squat jumps are ballistic in nature and thus have a very minor deceleration phase—if one exists at all. But what’s wrong with getting some ballistics in every week? Nothing. It is going to help improve the athlete’s RFD.

Whatever type of jump you do (countermovement or non-countermovement), be consistent. Do it on the same day or same phase of the week

Mladen Jovanovic:

To use jump training for estimating “readiness” or NMF (neuromuscular fatigue), one needs more sensitive tools and methods. Simple jump height will not do it because one can have high NMF and still perform countermovement jumps (CMJ) to the same height. What changes is the way that height is achieved, or the “process” behind the jump. Height is just an outcome. Please note that I am talking about estimating readiness and NMF is not a performance indicator.

I would also tend to agree that the more “reactive” the jump, the more it might tell you about NMF. Using 20kg CMJ might not be sensitive enough to estimate NMF since athletes can “grind” it through.

Modify the Long term approach

Speaking of using jump testing—or any other “readiness” estimate to individualize training—it shouldn’t happen acutely. In other words, we are looking for trends and creating a longer-term “prescriptive model” for an athlete based on reaction trends, rather than jumping on “red flags” to adjust daily workouts. So what if your HRV is lower by 10 than yesterday, or your jump power is lower by 5%? We need to rule out normal biological/measurement variability

Dan Baker:

When I worked with Olympic divers, we did squat jumps (no countermovement or arm swing), countermovement jumps (no arm swing), and a vertical jump with arm swing that mimicked a dive take-off (BVJ). The SJ and CMJ are just diagnostic tools to improve the most important, sport-relevant jump test, the BVJ. The SJ is thought to represent the contractile capabilities of the muscles. The difference between the SJ and the CMJ is the extent to which the stretch-shortening cycle contributes.

So, if there is very little difference between the two (say <10%), then the athlete needs more SSC-type training such as jumps, plyos, etc. If the difference is large (>20%), then they may need more basic strength work (squats, etc). This ratio will also reflect the recent training content. So if we concentrate on heavy squats and heavy jump squats for a month or two, the SJ may go from, say, 40 cm to 42 and the CMJ from 46 cm to 47 cm—the SSC augmentation decreases from 15% to 12%. But in following up that block with lighter, faster jumps, depth jumps and other plyos, the SJ may remain unchanged. But the CMJ may improve up to 50 cm and now the augmentation is 19%.

Life on the Road with a Top 100 Pro Tennis Player

APA is a company that has built it’s reputation on being the Industry Leader in S&C training for Tennis, which is why we get to work with pro players like Alijaz Bedene, Ed Corrie and Dan Cox, as well as a whole host of pro players hungry to follow in their footsteps!

You might have seen that Alijaz Bedene was in the news recently after he recently became a British citizen.  Congratulations Alijaz!  You can see the full article HERE

So now that we have a Top 100 tennis player on our books and many more pros fast on his heels, it makes me ask the question………………….

What makes us unique?

 

Well for a start……………..

All of our coaches are Tennis specialists.  It is what we do.

We have a proven Training system for getting results that is specifically designed for Tennis

All our coaches understand that coaching is about more than our knowledge.  Yes all our coaches are highly qualified, know about correct exercise technique, nutrition and writing programmes etc. but we also believe in coaching the person as well as the athlete – we go the extra mile to really get to know our clients beyond the hour-long training session so you stay committed.

Now, if you read the last post on Andy Murray you’ll know I promised to follow it up with some insights on working with Alijaz Bedene.  I’m delighted to say that Alijaz’s S&C coach Martin Skinner has agreed to write a guest blog.  In this blog he will share some insights on how he gets the best out of not just Alijaz but any client for that matter.  It links really well to the point above on coaching the person as well as the athlete.

 

Life on the Road with a Top 100 Pro Tennis Player: By Martin Skinner

 

About me

My name is Martin Skinner and I’m a Strength and Conditioning (S&C) coach currently working within tennis. I’ve been lucky enough to work with one of the best teams in British tennis at Gosling International High Performance Centre, which is in my opinion cultivating some of the best young coaches in the country. Tennis director Matt Willcocks, who gave me my break in tennis in 2008, spotted my potential and gave me the opportunity to start my career within tennis for which I’m forever grateful. I started off learning my trade as the apprentice of Daz Drake whom has been very knowledgeable and a great mentor over the years. The guidance of both Matt and Daz has shaped my coaching philosophy to what it is today. That’s not to say it isn’t still evolving, however the values these two people have given me never change. I started my S&C career just like most people having only a few hours of S&C work a week with predominately U12’s and some juniors whom were as keen as I was to improve and learn. From these few hours a week I began to work with some full time players, that is where I got my break in S&C. As soon as you get an athlete whom you can work with more than once a week the rate of improvement will rocket if you seize the opportunity. These are the small gems that get you noticed by other coaches and parents and to cut a long story short this is how I have ended up coaching where I do today.

That’s a little snap shot of how I was given the opportunity to become a full time S&C coach. I had never envisaged that today I would be writing a blog to other aspiring S&C coaches, so for this opportunity I’m very humbled and grateful and I hope you find this useful. Many people are excited by what happens in professional sport and what goes on behind the scenes with elite athletes and teams. I will attempt to give you an insight into what I’ve found makes the difference to a tennis player’s performance.

Aside from having a very effective and consistent physical pre-season, there has been an ongoing underlying factor that cannot be tested during any fitness test. This was the coaching of the person, not the player and instilling belief. These are probably things you have heard before? If not! Then in my opinion these two factors are single handedly, the most important when coaching an athlete. They are not only the metaphorical “icing on the cake” but are key ingredients to the whole cake. I will now attempt to explain how I utilize these two ingredients with my players.

Coaching athletes vs People

Firstly what I mean by coach the person and not the player is you must start to understand how the “Beast” operates throughout their daily life. This will allow you to be able to change their performances on the practice court, gym and most importantly be more effective during matches. For example if your player is always late or just on time to practice, you will find they are the same off the court. This may seem like a trivial matter and simple to rectify, however you may find this tougher than you might think to effectively change the actual person’s habitual behaviors. Many coaches might use punishments in the gym, on the court or a fines system to change an athlete’s time keeping during practices and it may work! But this will probably only change their attitude towards their sport not how they operate in daily life, which is the most important change as they will start to be more professional and demand a higher level of their entire lives. These perceived to be small changes will have massive impact on a player’s every day life, which will serve as a platform to perform further changes in building belief. For example once a matter such as time keeping is under wraps you give your self the opportunity to use phrases such as “no body is working as effective and professional as you right now”. This will massage their ego but will actually start to get them to change what they value and essentially how they operate. Never underestimate the small changes and the platforms they open up for you to improve the person, which supports the development of the player.

Do you have the belief in your players?

Now I would like to discuss the second ingredient to a successful player “Belief”. Belief in your ability and physical attributes is much stronger than that of any 1RM squat or PB in a Yoyo test. Instilling the belief that the player is the fittest and most powerful player on the court and almost superhuman, can give the player that mental strength they require to apply all that hard work from the gym and on the track to the match court. Some players who don’t have that belief can find themselves powerless to putting their physical abilities onto the court. This can be the margin between winning and losing. People may be reading this thinking ok great but where do I start instilling belief? Firstly you get to know the person as discussed earlier then you need to make sure that as a team you are all singing from the same hymn sheet. Not just the coaching team, but the player’s whole support network: parents, siblings, girlfriend/wife, tennis coach, psychologist, physiotherapist. The list may be even longer for your player or team. You need to immerse yourself in the athletes whole life this is the only way to build trust with your athlete. If you’re the coach who is only there when you’re being paid then high performance sport is probably not for you. To enable you to know the “Beast” you are trying to mold you must understand how they tick. So if you can get the support team around the player to believe in them whole-heartedly then the athlete will begin to believe. If you are managing a player and a member of your team doesn’t whole-heartedly believe that this player is capable of amazing things then they can start to be a part of the problem. Therefore everyone needs to tow the line, know the goals, core values of the team and live them if they don’t its probably best you limit this person’s involvement in the team.

A few helpful tips that I got from a fellow coach were to start altering the language you use around a player. For example; if you say “morning bud how are you?” this may give the player an opportunity to think too much about maybe a slightly disturbed sleep etc. We as a team changed this to “Morning champ looking strong today!” or Beautiful morning for winning isn’t it?”.  This may seem extreme to some coaches but these small boosts in positive language start to rub off on the player and the whole team. Never underestimate the power of positivity!! However please don’t think for a second that you can instill belief in a player’s ability without them actually having some substance. So you have to make sure that the attributes of their game that you are trying to build belief or confidence in is actually there. So if your using language like “no one can outlast you on the court, you never miss a ball!!” but your player can’t last 3 sets playing 3 hours in 28 degrees heat, then your words will stop instilling belief and start to instill questions in your ability to see their strengths and weaknesses.

 

Conclusions

In summary you must firstly coach the player not the athlete: players are complex and to get the best out of them you must know how they operate. Secondly build confidence and belief by taking your player’s best physical attribute and reinforce how good that attribute is!! Then finally immerse yourself in their life on and off the court, give them the opportunity to feel part of a family that values and believes in them. These are the two gems I found over my ten years of coaching that are not taught on any course or in any manual, but are what can separate a good coach from a great one.

What makes Andy Murray the best in British Tennis

Today I had the pleasure of observing the latest Master Performance Coach (MPC) Award taking place at the National Tennis Centre.  The highlight was getting some insights on what makes Andy Murray one of the best players in the world.  Since writing this block APA athlete Aljaz Bedene has been installed as the official British number 2, so stand by for some of our own insights from APA coach Martin Skinner on what makes Aljaz one of the best players in the world too!!!

For those of you who aren’t familiar with the National coaching qualifications framework, the MPC is level 5 on the coaching ladder, which is the highest coaching award in Tennis.  Included in the list of candidates were a number of ex professionals including Anne Keothavong and Mel South.  So it was a great opportunity to get some insights from them and Emma Anderson, physiologist to the latest Davis Cup team versus USA, as well as Louis Cayer, Tennis coach to the Davis Cup team.

I went along to sit in on the strength & conditioning module.  There are approximately 8 modules on S&C that the tennis coaches will learn about during the duration of the qualification.  Today I was there to listen about ‘energy system’ training.

After 60 minutes theory on anaerobic and aerobic energy systems the group went into the lab to do a practical.  Six ‘lucky’ volunteers had a go at:

 

  • Anaerobic capacity test- 30-second Wingate test

 

After a 5-minute warm-up the athlete did two short bursts of four pedal strokes to get ready, firstly at sub maximal and then at maximal effort.  Then after a short rest they were asked to stay in the saddle and pedal flat out for 30-seconds.  This test was designed to measure anaerobic capacity.

  • Repeated sprint test / Power depletion test

 

Ema Anderson, the physiologist took us through a Wingate bike version using 6 x (7-seconds with 23-seconds rest).

 

You can also do this using sprinting protocols such as:

 

6 x (30m with 20-seconds rest) or 12 x (20m with 20-seconds rest)

 

This gives you an idea of how much power they can hold on to and actually reproduce.  This is very relevant to Tennis performance.  Unfortunately it is a test which very few Tennis players have done at the NTC.  Often the athlete and their coach aren’t willing to do a test like this fearing it will ruin their tennis training due to its high demand.

Aerobic Capacity Treadmill test: VO2max test

 

I’ve written about the protocol they use at the NTC in a previous post which you can read HERE.

 

So what?

 

To be honest, these kind of tests might not immediately tell you much about someone’s tennis fitness- ie., how well they cope with the demands of the game.  Being efficient on the bike is different to the treadmill which is different to running on the tennis court.  But it is so useful to know what kind of general condition someone is in before they step on the court.

If someone is getting tired on court maybe it is as simple as they are not in shape ‘generally’ and have a low aerobic and anaerobic capacity as measured by the tests above.  Or maybe they have a good capacity but have poor power because they can’t repeat it, and the anaerobic power tests would show that too.  If you at least know this information about your player it can certainly help you rule certain things out if someone is struggling on court to meet the demands of the game.

So what makes Andy Murray so much better than the rest?

andy murray

Louis Cayer commented that he was very surprised that Andy got his heart rate up to 180 bpm when rallying during training at the Davis Cup.  At the same time one of the other younger squad members was at 160 bpm.  Now you might conclude that the younger player was more conditioned.



This is why you need to know your player and know your sport.  Andy is most probably one of the most highly conditioned players on the Tour.  Andy simply has an unrivalled work ethic and even during rallying will work his feet and body really hard to get in the perfect position, bending his knees and being quick with his adjustment steps.  Unfortunately I don’t have a clip of this but here is a clip of another great role model, Kei Nishikori.  This session isn’t necessarily of the intensity I am talking about here which would get his heart rate up to 180bpm, but he is someone who I imagine has a similar desire to work.

When Louis Cayer showed the other player his heart rate (who was hitting with Andy) he started to work his legs more and move his feet and he too was able to get his heart rate up.

What Andy has according to Ema is a desire to work hard during every practice.  Despite being 6 or 7 years older than the younger players in the Davis Cup team he was as determined as ever to set the bench mark for the others to be judged against.

According to Ema, Andy was more ‘comfortable being uncomfortable,’ in that he was able to cope with a high intensity drill of 1-minute rallying which would work him at around 190 bpm.  Importantly he could do two things:

  1. Keep the quality of the ball characteristics of his shots very high- even when working at near his maximum heart rate
  2. He could repeat this quality with only 30-seconds rest, and he was ready to go again

The next group of British Tennis players looking to follow Andy into the Top 100 and possibly Top 50 would certainly do well to take note.   Are they prepared to go somewhere that ‘hurts’ physically, embrace the grind, and if so are they good enough players to be able to keep the quality going over and over?  Andy always had the natural talent for the game.  Don’t believe me- one of my informants tells me Andy only played four hours of tennis per week until he was 15.  You need to be pretty talented to win major junior titles if you only play four hours per week!  But later in his development he trained his ability to out last his opponents with a desire to work hard in training.  That’s one of the aspects to Andy’s character and ability that separates him from the rest.

Train children like the pros?

I definitely encourage Tennis coaches to use heart rate monitoring.  It was certainly a great tool that can inform some really good discussions within the Tennis team.   The group discussed whether children need to be training like this.

Ema said it is important to remember that Andy has trained this tolerance over several years of working at this level of effort.  He has 6 or 7 years training in the bank of this type as a pro working with a full-time fitness team which until recently was Jez Green and Matt Little.

I have no problem with children pushing themselves in similar types of drills at certain points in their training week.  But I believe in an important philosophy:

Minimum effective dose versus Maximum destructive dose

I personally like to keep my ace cards in my pocket for when I need them.  Yes, it is important to expose the younger players to the demands of the game (as it is played at the pro level) by doing some pretty tough drilling.  This way they have an understanding of how tough the game really is at the top level.

But equally, you don’t need this to be the focus of training with younger athletes.  You will find they need less stimulus and will still adapt physically.  Also, this will enable them to execute their techniques optimally during the ‘skill hungry’ years, in the absence of lots of fatigue.

Designing drills

The coaches on the MPC Award were split into three groups and had to design a drill that they thought would bias each of the three energy systems:  

  1. Alactic ATP-CP system
  2. Lactic acid system
  3. Aerobic system

This created some really good discussions and helped raise the coaches’ awareness to the actual physiological stress on the body.

Alactic ATP-CP System

For the Alactic ATP-CP system, the group asked the player to hit four shots on the full run, and have 30-seconds rest between.  The heart rate of the player consistently rose to about 85% -90% maximum heart rate during the recovery period.  The player said they felt they hadn’t had enough time to recover in 30-seconds, so it became more of a speed endurance drill.  It was suggested to either reduce the number of shots to 2 or give them longer rest up to a minute.

Lactic Acid System

For this drill the plan was to make the player run side to side for 1-minute with 30-seconds rest between.  The time of 1-minute is a really interesting value because this represents the upper limit of the lactic acid system (usually around 20-60 seconds).  So it really depends on how capable the player is in keeping high quality for 1-minute.  If they can’t this will quickly become a poorly executed drill or the 1-minute will only be sustained if the intensity is dropped and the drill is done for aerobic work with maybe only 15-seconds recovery to keep heart rate up.

Aerobic system

 

The group wanted to do a continuous drill for 5 minutes in a three, with the person on their own hitting to two players on the other side for the full 5 minutes.

My eye brows raised because I know that 2 vs. 1 is usually done as a Lactic Acid system drill, for 30-60 seconds at high intensity, and they rotate around so the work to rest ratio is 1:3.

 

Not surprisingly the player’s heart rate quickly rose to 92% of their maximum and they stopped after 1-2 minutes and said that it was an unrealistic drill!

The team agreed to keep her moving but in a smaller area either staying in the middle or staying in one corner like you saw in the video with Kei Nishikori

 

Summary

 

Well I hope you found this blog interesting.  I think it is vital that any performance coach has an appreciation of the effect of someone’s fitness level on their ability to perform on the court; and most importantly the effect of the drill on the player’s ability to perform on the court!

Why the midthigh clean pull is all you need to develop power!

This is the second part of my instalment on the presentations I listened to at the Middlesex Student S&C Conference a few weeks ago!

 

I have written several times about Power.  Check out this blog here.  However, it is always great to hear people speak who are at the cutting edge of the research in strength and power development.

 

So it was great to listen to this next session.

Head of Sports Science Support for Salford City Reds Rugby League Football Club.

Power and RFD Methods and Research

 

Study 1

 

Paul took his through the findings of his research in the J Strength Cond Res 25(12): 3269–3273, 2011.  This first study looked at variations of the Power Clean.  All variations were carried out at 60% of 1RM Power clean to determine force-velocity characteristics of each.  The variations included power clean from the floor, a power clean from hang (low), and two versions from the mid-thigh hang (high).

Findings:

  • mid thigh clean pull (at 60% 1RM of Power clean) has highest value of Power (Watts), Force (Newtons) and Rate of Force Development (N/s)- see graph below

Discussion points:

  • the reduced bar displacement  from a hang position requires greater acceleration of the bar
  • Other research was cited which notes time to peak RFD during midthigh clean pulls, at all loads (30, 60, 90, 120% of 1RM Power Clean) was shorter (Peak at 30% 1RM, 99.8 milliseconds) than time to peak RFD in both vertical jumps (194.7  milliseconds) and countermovement jumps (263.3  milliseconds).

Application:

  • the use of mid thigh power clean variations to develop Force may assist with the development of sprint speed.
  • mid thigh clean pull and mid thigh power clean have practical benefit in that both are easy for less experienced athletes to learn and require less technical excellence.
  • during a strength-based Mesocycle, it is suggested that the midthigh clean pull be used because this can be performed at loads >100% 1RM power clean, because the catch phase is not required.
  • during a power-based Mesocycle, it is suggested that the midthigh power clean may be advantageous because it results in higher peak power output, peak Fz, and RFD compared with the other variations of the clean.

Study 2

 

Paul then took his through the findings of his second research study in the J Strength Cond Res 26(5): 1208–1214, 2012.  This study specifically looked at the force-velocity characteristics of the mid-thigh clean pull across a range of loads.

 

Findings:

  • peak power occurred in mid thigh clean pull at a load of 40% 1RM of Power clean
  • this corresponds to a bar velocity of 1.65 m/s
  • peak force occurred in mid thigh clean pull at a load of 140% 1RM of Power clean
  • peak rate of force development occurred in mid thigh clean pull at a load of 120% 1RM of Power clean

 

Comparison of peak bar velocity across loads

midthigh clean pull bar velocity

 

Seeing as there is a lot of current interest in velocity based resistance training it was interesting to note the velocity associated with the mid thigh clean pull during peak power.  According to Paul if you wanted to assess someone’s Power clean 1RM who can’t catch the bar it might be possible to use the weight which corresponds to approximately 1.25 m/s on the clean pull and use that as a guide to predict power clean 1RM!

Discussion points:

  • these findings are in contrast to the previous findings of Kawamori et al. (2006) who identified that peak power (2,228.9 6 192.3 W) was achieved at 60% of 1RM (power clean) when comparing loads of 30, 60, 90, 120% of 1RM
  • peak power achieved at higher loads by Kawamori et al. (2006) is likely a result of the subjects being experienced collegiate weightlifters who may demonstrate a higher level of competence in such exercises
  • at 140% 1RM there is a 69% decrease in velocity,  in contrast to only a 10.6% increase in Force!
  • stronger individuals maximize power output at a different relative intensity than less strong individuals
  • It is likely that the higher loads (70–80% 1RM) previously identified to elicit peak power output during the power clean and hang power clean are as a result of the additional phases of the clean (first pull and transition to mid thigh, or transition to mid thigh only) permitting greater time and range of motion to accelerate the bar before the second pull phase, technically unloading the bar because of its momentum
  • the load that appears to elicit peak power output during this study is similar to the loads identified during the squat jump by Stone et al. (2003) of 40% 1RM

Application:

  • when training to maximize peak power output, lower loads are recommended. Moreover if the goal is to train force, impulse or RFD higher loads, of 120– 140% 1RM, are recommended
  • such exercises should be periodized to progress from max strength (Force) to peak power, in a sequential manner; therefore, it may be beneficial to begin at high loads (>100% 1RM) and progressively decrease loading to maximize velocity and power.

Middlesex Student S&C Conference 2015 Review

Like many of us busy coaches, going to a conference represents a time for reflection before we get back to to our respective roles. I had the pleasure to attend the recent Middlesex University Student S&C Conference which I believe is in it’s sixth year, with over 100 delegates in attendance.

If you’re a Strength & Conditioning coach then this is the must go to event. I thought it would be appropriate to feedback a few of the key messages and applied methodologies presented at the presentations I made notes on.  I will discuss two now and I’ll send you the remaining two in a week’s time so watch out for them every Friday!

Key challenges:

  • Limited availability of training in-season: 111 days out of 304 days, which doesn’t account for international fixtures so even less time for Premiership clubs to work with pros on S&C.
  • It is imperative therefore to maximise use of small sided games (SSG).  
  • Effective aerobic protocol 4 x 4-minute @90-95% Heart rate maximum

SSG can be effective for high intensity aerobic training but you need to be able to modify the rules to account for differences in players.

Barry is actually moving away from SSG and designing Position Specific training drills.  For example, a slalom course that replicates sport specific movements.

Resistance Training:

Research at Premiership Academies shows that there is no further increase in training load from 15 years to 21 years in footballers.  There doesn’t seem to be opportunities to further load them after they reach 15, and approach pro contracts.  This typically amounts to 2 S&C sessions per week.

Concurrent training:

Ideally he would like players to have several hours between football and S&C sessions but players usually don’t want to leave the training ground and come back in the afternoon.  So they usually either have a short break or go straight into their S&C session after their football.

We know that doing endurance training after strength training can ‘blunt’ the neurological response.  But some times you might want endurance to be the focus, in which case this may be desirable if metabolic gains are a priority.  Also consider that performing a football session followed by an S&C endurance session in glycogen depleted state may limit availability of energy and increase aerobic performance.

Monitoring: 

In his work with Liverpool FC they use:

  • GPS- regularly
  • Subjective questionnaires- less so now
  • Biochemical (saliva)
  • Performance indicators- less often

He said the GPS data has measurement issues as it is not sensitive enough to all the small changes in movements.

(Interesting side note- my friend Alex Cockram said that the EIS are using joint position tools to measure knee angle to indicate how many lunges and decelerations take place in badminton as a way to gauge mechanical load!!!

In season Weekly Schedule: 

Doing high training loads (say >6000m running versus >1000m) limits player availability for the next weekend.

Key take home message- take 2 days recover after match days

Bad approach:  GAME > OFF > Train (High Load)  

Good approach: GAME > OFF > Team recovery (Low load)

Working in Teams:  

Survival in the game is about social skills not just coaching skills!

Are you ‘Organisationally Socialised‘ to understand the world through other’s eyes and manage relationships with key stake holders in the sport.  They may appear to want to work with you but behind your back they may be looking to get you out.

Be aware of a wolf in sheep’s clothing.

Coaching Philosophy

Dave works in consultancy, research and teaching and in his role the University expects him to develop viable businesses that can justify his salary.  In simple terms he needs to earn the university double his salary! So this talk was a bit of a philosophical look at building business, friends and success.

 

Getting things done:

He recommended we check out the book ‘Checklist Manisfesto’ (Atul Gawande).  It talks about the importance of using checklists in business to make things work more efficiency.

Often things go bad not because you don’t know something but because you fail to apply the knowledge!  Remember, wisdom is the application of knowledge!

The four D’s:

  • Do it
  • Delete it
  • Delegate it
  • Defer it

Communication:

-ITEAL acronym when managing your team

  •  ‘I’ ncident
  • ‘T’ houghts
  • ‘E’ motions
  • ‘A’ ction
  • ‘L’ earning

This is a good way to help you reflect on situations (incidents) that were either positive or difficult.  What were you thinking? How did you feel? What action did you take and what do you learn from it?

Negotiations:

  • Think Win-Win
  • Be clear and consistent
  • Start nice
  • Stick to your principles [breaks]
  • Be forgiving

Meetings:

To stop meetings getting boring and keep them productive Dave always applies a few simple rules.  Rather than setting an agenda in advance, it is useful for the chairman of the meeting to agree the Top 3 Questions the group will discuss in the time allocated for the meeting, and set a time frame to discuss each question.

There will be a time keeper to keep the people to time and a Yellow card will be issued to anyone who goes off topic!!!!
