Youth Strength training

Following a Facebook discussion on the GB judo underground page I have decided to write a post about strength training for adolescents. There appears to be two common misconceptions, firstly that resistance training is bad for adolescence and secondly that they should be working on only judo skills. Hopefully I will dispel both of these.

Long-Term Athlete Development:

The LTAD model was introduced to British judo in 2006 and around this time to most sports in the UK. I am not going to discuss the rights and wrongs of this model in this post (although I am happy too in the future) but I will highlight what Balyi suggests in relation  to strength training.

Balyi suggests there are “windows of trainability” based upon an athletes developmental age (where they are in relation to maturation and peak height velocity). There has been huge criticisms of this because there is very little evidence to show there is accelerated adaptation in these stages but much of this criticism is based upon a lack of evidence and not evidence to the contrary. Balyi’s work did do something great for sport in the UK though, it suggested children could do strength training younger than 16yo and there is a lot of evidence, and consensus statements to suggest this is fine.

Figure 1: Windows of trainability presented by Balyi.

Strength training is dangerous for adolescence:

There is a wealth of evidence that structured, progressive and guided strength training is hugely beneficial to children whether athletes or not. I work in an environment where we coach full-time athletes and to see “good judo players” come to us at 16-18yo who have never lifted is often difficult for us to comprehend (the judo is often very limited too but that’s another story!). Here are some of the consensus statements shared in the FB group with their conclusions underneath and these are just some of the many:

https://www.researchgate.net/publication/256929167_Position_statement_on_youth_resistance_training_The_2014_International_Consensus

“A compelling body of scientific evidence supports participation in appropriately designed youth resistance training programmes that are supervised and instructed by qualified professionals. The current article has added to previous position statements from medical and fitness organisations, and has outlined the health, fitness and performance benefits associated with this training for children and adolescents.”

https://www.ncbi.nlm.nih.gov/pubmed/11019731

“With qualified instruction, competent supervision, and an appropriate progression of the volume and intensity of training, children and adolescents cannot only learn advanced strength training exercises but can feel good about their performances, and have fun. Additional clinical trails involving children and adolescents are needed to further explore the acute and chronic effects of strength training on a variety of anatomical, physiological, and psychological parameters.”

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3445252/

“Youth—athletes and nonathletes alike—can successfully and safely improve their strength and overall health by participating in a well-supervised program. Trained fitness professionals play an essential role in ensuring proper technique, form, progression of exercises, and safety in this age group.”

http://www.tandfonline.com/doi/abs/10.1080/02640410310001641629?journalCode=rjsp20

“Based on the scientific evidence and expert opinion, resistance exercise can be positive when part of a balanced activity programme. Providing that professionals who understand the key principles of child growth and development adequately screen and supervise participants, then the combination of low risk of injury and positive physiological, psychological and sociological benefits can promote health and perfor- mance in all groups.”

 

Common themes throughout these are –

  • Progressive/structured
  • Supervised
  • Safe

You should focus on skills:

I would argue that for 10-12yo’s (just a guide because we’re talking about developmental age) skill training should be prioritised. They’re in What Balyi would describe the “learn to train stage” and I wouldn’t agree with this structure approach. This doesn’t mean they cannot do both and it doesn’t mean the coach cannot support the athlete in this. For example, how many coaches “walk around the mat” to “flush lactate” after a session, especially Randori? So with a young group why not practice unresisted squats or squats with a broom handle to “flush out the lactate” instead? Whether pre-adolescents need to flush out lactate or not is another questions but regardless wouldn’t this be a better way to end the session?

So what should you do?

I understand that this is an area that worries parents (and probably coaches) quite a lot and I am not trying to be flippant in this post. The real question is what should you do? Well, the answer is above really – structured/progressive and supervised. So how do we do this?

My honest opinion, and some won’t like it, is that I wouldn’t trust anyone to take my S&C classes without at least degree knowledge and if I was a parent paying I’d want an S&C MSc and UKSCA qualifications. The days of trusting someone who is a “personal trainer” who has probably done a two week YMCA course is gone I am afraid. If you get the right person then the structure and progression should look after itself.

Summary

There is a wealth of evidence to support the use of strength training in children and adolescent, the general consensus suggests this should be structured, progressive and supervised in order to be safe.

I think it would be good to have some sort of coach education and parent education in this area because judo is a demanding and often brutal sport, strength training will help athletes throughout he tough transition stages and help prevent injury.

Training Load in Judo

A new research project I am embarking on is considering the use of training load in judo. I am working with one of Comberton judo clubs coaches/athletes who is a student at Anglia Ruskin University where I lecture.

What is training load?

In it’s most simple form training load is the amount (volume) and the intensity (how hard you work) of training in a given period, often a day, week, or month. It has been suggested that training load monitored well can help predict injury (Gabbett, 2016; Gabbett & Domrow, 2007) but other reasons include appropriate planning and ‘peaking’ for an event.

For a few years now I have monitored athletes training load and in recent years I have considered training load in terms of fatigue (chronic/28days) and fitness (acute/current daily load). I started doing this using dropbox and excel, then moved to google docs and I am currently using Athlete Analyser. The numbers we get from the athlete are basic, number of hours training and intensity (RPE), this worked in google docs and excel pretty well but now that we’re collaborating with Athlete Analyser it is much easier and we can collect a lot more data.

 

Reading the data…

The numbers produce a graph and this allows us to consider training status and likelihood of injury. Once we have collected more data I will write a blog post showing how we use the graphs to predict injury and plan a taper.

What is our research looking at?

Myself and Holly have been working with the team at Athlete Analyser to develop these training insights because one of the issues we faced with dropbox and google docs was athlete adherence, they’d constantly need chasing up to fill in the documents whereas now the Athlete Analyser app alerts them on any smart phone and reminds them to record their data.

Our research project, which is part of Holly’s final year project at Anglia Ruskin university, is considering training load as a predictor of injury and a variety of other assessments that might help us predict or avoid injury such as strength, functional movement, percentage body fat, flexibility and cardiovascular fitness. We also work closely with our club physio Ben Whybrow in terms of injury prevention, I am closely monitoring the taper to see if we can develop research on this and I am working with a masters student on some periodisation research that I will write about in another post. Our participants in the study are full-time athletes and AASE athletes at Comberton Judo Club.

I’ll be posting more about this research and other work we’re doing in due course! Please ask any questions int he comments below.

What a great weekend for Comberton Judo Club!

This weekend was the 2017 Eastern Area Closed. This event decides who are the area champions across a variety of ages and it is used to ‘rank’ clubs within the Eastern area.

Comberton judo club finished top of the table for the first time. We took 18 athletes and to be honest we wanted more, we were aiming for 30! We were missing some strong athletes too who I am sure would have won a medal. You can read more on our medal haul here and see some pictures here.

The reason for this post though is not about our performance at all. This has been a year of turmoil for me personally and the club and things are coming together really well. We won gold for the women team in May at the Eastern area team league and the men secured silver. We have five athletes competing at the British junior and senior championships in December, we have been to Japan, we have competed in two European cups …….. things really are great. But this weekend was different, it wasn’t all about performance and making those ‘inch by inch gains’, it was about the club coming together, it was about the younger players being able to watch the performance players, for me it was great just to coach kids again!

I am pretty pleased with how things are going, creating a culture for a performance team is not easy so to have to do it twice in two very different environments has been a challenge but right now, things are great!

Some pictures from the Eastern area closed, you can see more here

PhD Thesis Submitted…

It feels like ages ago now but on the 18th September 2017 I finally submitted my PhD thesis – “A Time-Motion, Technical and Tactical Analysis of Lightweight Women’s Judo”. This is a journey I started on in 2010 and to be honest it’s felt longer lol

I am in the process of editing three new papers from the experimental chapters (one already published). One will be on techniques and tactics, another on penalties and another one on time-motion analysis.

I have a mock viva on the 21st November and the actual viva on the 24th. Hopefully just minor amendments after that.

Big changes……

Lots of people have asked me what is going on with “my job” at Anglia Ruskin so I thought it best to clarify my current position. I am a senior lecturer at Anglia Ruskin and was not employed for the judo at all, this was all something I did “as extra”.

In 2009 I started a judo club at Anglia Ruskin University, I remember telling the SU staff that I wanted it to be the best university judo team in the country and being laughed at. In 2010 the European judo union moved the performance coach awards to Anglia Ruskin with me as the course leader and this was the start of a “judo programme” that consisted of a high performance coach education pathway, full-time athletes, a community programme, the Advanced Apprenticeship in Sporting Excellence, recreational judo and a judo research group. I am quite proud of what was achieved here, predominately in my own time and with no extra pay. As much as I enjoy research and coach education my real passion is in athlete development and ironically it was this part of the judo programme that would prove its eventual downfall.

I set the target of providing 20hrs of training a week and we managed this with the same support as other clubs had (often less) for a sustained period of time but eventually things change. In my time managing and coaching the athletes at Anglia Ruskin they have performed very well in the British University and Colleges Championships, the results are shown below for this –

  • 4 x mens team champions at BUCS (the only Anglia Ruskin University team to win BUCS) plus one bronze
  • Women’s team bronze
  • 10 individual dan grade gold medals
  • 3 individual dan grade silvers medals
  • 10 individual dan grade bronzes medals

Over the years thats is 288 BUCS points for Anglia Ruskin University. Add to that around 15 peer reviewed journal articles specific to judo, three judo PhD students, countless students who have attended the university because of judo, income generated and the marketing i’d say it’s not a bad job.  Still the head of sport decided he didn’t want me involved in the judo anymore, this is his choice to make and I accept that decision.

So I move on! I will stay at Anglia Ruskin as a senior lecturer, a job I have enjoyed very much over the years to be honest and the one I am actually paid for. I think it is fair to say that my club that I have run for 18 years, Comberton Judo club, has suffered over the past 5-6 years with my main focus being on the Anglia Ruskin Judo Programme and the good news is that is changing and it is changing fast! Very fast! Comberton Judo club will now provide full-time training and many of the students who previously trained within the Anglia Ruskin Judo programme have moved to train with us.

I am now more positive and more confident in the judo I can deliver than I have been for a very long time, this might be a forced change but in many ways I feel it will be for the best. I would really like to thank the coaches and athletes who have stood by me throughout this two year period – Natasha Collins, Alex Hemming, Holly Newton, Ben Caldwell and Tara Fitzjohn have been particularly affected by all of this and have been strong throughout.

I will follow this post with another one about all the changes coming on board at Comberton Judo Club in the very near future (to be honest it might take more than one post!). In the mean time I wish the Head of Active Anglia and his new Head Coach, Michael Stewart, all the best for their venture into running a full-time training programme and we’ll see you on the mat!

Soremade!

Our current research

It’s a long time since I have posted about our judo research at Anglia Ruskin. Here is a brief overview of what we’ve done in the last year or so and what we’re working on at the moment.

Firstly who is doing the research….

Bob Challis – My PhD research focusses on the temporal, technical and tactical components of lightweight women’s judo and how these differ from men’s judo and heavy weight judo. I believe lightweight women require different technical/tactical training to men and heavyweights as well as different strength and conditioning because their contests are different. Outside of my PhD research i am interested in talent development, structures around talent development, talent ID, periodisation and monitoring training load. Managing the full-time athletes here means I can consider these from a much more applied perspective than most researchers.

Glenn Miller – Glenn is a PhD student and is looking at Nage-waza across the Olympic qualification period for the Rio Olympic games. He has coded/is coding 8 competitions in this period, the two world championships and six Grand slams. This is over 200hrs of video.

Natasha Collins – Natasha was working as a research assistant, within this role she helped publish research that mainly considered British judo from a technical perspective. Since then Natasha is mainly coaching but is looking at some research and will probably publish in the areas of temporal analysis and shido’s in judo in the next year or so. Natasha is also involved in the application of our research into the training group.

Katrina McDonald – Also a senior lecturer at the university Kat focusses on athlete education as her PhD and has recently published with Maki Tsukada on the coach athlete relationship in judo.

Tara Fitzjohn – Tara is an MSc student. Her work is considering the use of performance analysis in judo. She has interviewed several high performance judo coaches to ask them what they thought would be useful in coaching and then created a code window based on this information. She has now coded around 200 fights of the athletes in our full-time training group and we will use this in our coaching. In the Final stage she will interview the athletes and coaches about how useful it was having this objective information to coach the athletes.

Paul Robertson – Another PhD student, Paul is looking at where coaches look during a judo contest and what they pay attention too. Around 20 coaches have watched judo contests as if they were mastoid whilst wearing eye tracking glasses.

We also have some other judo projects that may lead to publications in a variety of areas including biomechanics, training load management, decision making and the psychological impact of injuries on judoka.

Some of our outputs to date include:

Challis, D., Scruton, A., Cole, M., & Callan, M. (2015). A Time-Motion Analysis of Lightweight Women’s Judo in the 2010 World Championships. International Journal of Sports Science and Coaching10(2-3), 479-486.

Miller, G. A., Collins, N. A., Stewart, M. J., & Challis, D. G. (2015). Throwing Technique and Efficiency in the 2013 British Judo Championships. International Journal of Performance Analysis in Sport15(1), 53-68.

McDonald, K., Tsukada, M., & Chung, H. (2016). Understanding the female judoka’s” coach-athlete” relationship: a British perspective. ARCHIVES OF BUDO12.

Next post I will look at how we are using this in day to day coaching and judo education. In the mean time if you’re interested in doing a judo specific research project then please contact us at judo@anglia.ac.uk.

Leadership

Firstly, I am sorry this is not a judo post!

I am seeing lots of posts on my facebook page at the moment about how intollerable Trump is. I don’t really read them to be honest, not because i don’t care but because in the main most of the people posting know little about leadership. Over the last nine days I have read some facebook posts that show true leadership though and it is those I want to write about. Before I get to them though a little background.

I joined the army at 15yo as a junior leader, probably one of the best decisions of my life, if not the best decision. As someone that joins the army as a soldier you nearly always have the ambition of becoming the Regimental Sergeant Major (RSM) of your Battalion, this is, for the purpose of this post ‘the boss man!’ The RSM is the Sergeant Major of the Seareant Majors, he is in charge of discpline, is generally feared and is usually considered the top soldier of the battalian, he represents the fighting men. As a young soldier you often imagine what sort of RSM you would be, would you be the streotypical screaming, shouting man of discipline or would you be the war hardened man of few words? There are examples of both across the movie world. There are some examples below.

Now we’re clear on what an RSM is like I want to be clear about something else, some of them are shit leaders! They just want to tick boxes, kiss arse and move on. They’re in camp, pacestick waiving, crayon eating spunktrumpets who got to where they are by kissing arse and doing a few courses. Some however inspire soldiers, these are the men who win battles and it is one of these I would like to introduce today.

WO1 (RSM) Steve (Spud) Armon is the RSM of the first Battalian the Royal Anglian Regiment. Over the last 9 days (the same amount of time Donald Trump has been president) Steve has walked the 9 highest mountains in the UK to rememebr the 9 members of the Battalian lost in Afghanistan on Op Herrick 6 10 years ago.

Steve is posting his journay each day on his facebook page in order to raise money for the army benevolent fund with the story of how each soldier died. I have screenshot some of the posts here:

Screen Shot 2017-01-29 at 21.05.31.png

Screen Shot 2017-01-29 at 21.06.01.png

Steve is without a doubt a soldiers soldier, he leads from the front and is the epitomy of leadership. He has an empathy with the soldiers and commands their respect from years of war fighting, most importantly he sees himself as a servant of the soldiers, a leader who is there to support, guide, mentor and inspire.

Maybe Donald Trump could learn a thing or two!

Anyway, the real aim of this post was to ask you to donate! So here’s the link 🙂
