With my PhD completed, I thought it would be a good idea to have somewhere where all the research can be accessed so please see the links below if you’re interested in lightweight women’s judo.

I asked this question previously, back in April, following the European championships and I am going to following a similar process here. I will look at world championships results all the way back to 2000 and compare them using a variety of methods. Firstly let us consider the team.
It should be noted that Alice Schlesinger is also a world bronze medallist and 4 times European medallist. Furthermore, Lucy Renshall was selected in u63kg but could not fight because of injury. She is the current European bronze medallist.
I think this is an outstanding team. Twelve athletes, five of them are current European, World or Olympic medallist. I don’t think anyone can criticise the strength of the team that went out to Baku. Maybe some would like to see more go and a less stringent selection process but that’s another issue.
So, is British judo getting better at a world level? Like previously I will go back to 2000 and consider results at the world championships.
The first criteria most would consider is the number of medals, crude but arguably fair. In this world championships we got one silver medal (Nekoda Smythe-Davis) and if we compare that back to 2000 we can see only last year we won two bronzes. Of course, you could argue 1 silver is better than two bronze, it certainly puts you higher on the medal table but then conversely it gives you less world ranking point. It’s neither here nor there to be honest. If you’re counting medals we got less.
Let us consider the results using world ranking points going back to 2000, this process kind of evens out the colour of the medals in my opinion.
I think it is fair to say that for a long period of time Great Britain was world-leading in judo. This has been less so since 1996 but even then British judo could expect 700+ points using this measure. There was then a period of time we went below this, even winning no medals for four world championships. People will cite many reasons for this, I think the break up of the Soviet Union certainly contributed to the break in our world-leading streak but what contributed to the drop from 2009-2017 is another question and is certainly not going to be answered here. If we’re asking about a rise in British judo you can clearly see us moving out of this dark period and starting to win medals again when using this points system, back to where we were between 1996 and 2007.
We can consider our performance against other nations too. If we look at our ranking in the medal table at world championships.
This table is a little harder to see a pattern in. You can certainly see we had better medal table positions in the first part (2000-2007) and that it is after 2007 the decline started. You can also see that 2018 ranks 7th in our overall performance when compared to other teams and that 2018 was our most successful year since the decline.
I think the other consideration is the retirement of Karina Bryant who would consistently win a medal, if not two at each world championships. I think Karina doesn’t get enough credit for her contribution to Great Britain performance over a very long period of time. When we talk about having a lot of funding, I think a large part of this is down to her.
The other question, of course, is world champions. Well, we haven’t had one of them since Craig Fallon in 2005 and this year was the closest we have come to one since 2009. Before that, it was Graham Randall in 1999 (we won 1750 points based on the above system in that worlds but it was on home ground).
So how do we conclude? Well, based upon medals we could have done better but let’s not forget we did have two 5th places and if both of these had won this would have given us over 1000 points making it our second most successful worlds this century. It’s also fair to say our two most consistent athletes did not have a great world championship, Sally and Natalie. This happens to everyone. A ‘normal’ result from them would have made this our second best worlds this century.
We should also consider the valiant efforts of Sarah Adlington who performed better than ever before and finished 5th as well as Jemima Yeats-Brown. Now, on the topic of Jemima. I’m a firm believer that when you make a mistake you should own up to it! I have always regarded Jemima as an athlete who would never perform and would also be injured for most of her career, and when I say always I mean I have voiced this concern for years. To be fair she has been injured a lot but in honesty, this weeks performance totally outshines that. She was outstanding. She fought with maturity, aggression, confidence and it was exciting judo! So I wholeheartedly apologise to Jemima and well done to those who supported her.
Last but not least, how could I end not mentioning Nekoda’s fantastic performance! What a great way to answer those who said last year was a fluke! She had a tough draw, she beat the current world champion and Olympic silver medallist in the semi-final, she beat Lien who although she is from Chinese Taipae trains at Komatsu and she beat the current European champion. She did great judo all day, was solid from the start and exciting to watch. Well done Nekoda!
So in conclusion, I think we actually had an unlucky world championships. I think this team could have produced more and therefore we are moving in the right direction in terms of world performance.
If you have any points or see a mistake please let me know in the comments below 🙂
With the fantastic results of the European championships this week there will be the inevitable response of how great British judo has become/is becoming since it moved to a centralised programme at Walsall but what do the numbers tell us?
First of all, this has been a valiant effort by the British team and I would like to congratulate all the athletes, in particular, the 5 that won medals.
Sally Conway – Silver
Ashley McKenzie – Bronze
Gemma Howell – Bronze
Lucy Renshall – Bronze
Natalie Powell – Bronze
So how do these results compare to previous years? I’ve decided to stick to this century and go back to 2000. It would be hard to compare going back much further and 2000 seems like a good break point to me. There are several ways to present this data, I could do what most people do and select the one that suits my agenda or what I want to say but I think that isn’t fair and to be honest, if I have an agenda its objectivity so I have decided to present the data in a number of ways and let the reader make up their own mind.
If we base performance solely on medal count then 2018 is our most successful performance this century (since 2000). Personally, I am not convinced medal count alone is a good measure but winning 5 medals, the most we’ve won in 19 European championships is great. Below I have broken our medal tally at the European championships down by year and equating medal colour to the current number of points awarded on the IJF world ranking list. I think this is a fairly good way of presenting the data.
If we ranked the results in order of points awarded then 2018 would be our joint 3rd most successful year. Table 1 shows all years ranked in points order.
Of course, there are the purists who would only like to count gold medals. Well, it is 12 years since we won a gold medal and in those 2006 European championships, we won two golds – Craig Fallon and Sarah Clarke. In fact, we have only won 5 European gold medals this century, the two above and Karina Bryant in 2005 and 2003, Georgina Singleton in 2002.
Of course, there are others ways to measure the performance, the number of fights won compared to the number of players competing (too much work for this post i’m afraid) and the quality of the fights are two examples. I did watch all the GB fights but I would want to watch them again without the emotion to judge that and give an opinion. My first impressions are that actually, our players are fighting very well at the moment. Natalie and Sally are extremely consistent and easily world class. This was Lucy’s first Europeans and she won a bronze, how Gemma has come through so many injuries and three weight groups to medal at this level is nothing short of miraculous and Ashley has achieved a second bronze despite fighting his opponents and the system simultaneously. If I was to pick one thing I find frustrating it would be this new habit of some British players to “beg for a score” or “beg for a score to be upgraded“. I don’t like this, I think they miss opportunities, particularly in transition to Ne-waza and arguing a score is arguably the coaches job, the athletes should focus on nothing but fighting. I don’t blame the players, there could be a number of reasons, lack of trust in the coaches, lack of faith in the referees, or the constant changes in rules (although not all athletes from all countries do it) to name a few.
So what do we conclude? Well based solely on medal count we’ve done very well, our best Europeans this century. I am sure most people would agree the medal tally of 2006 (2 golds and two bronze) is better than of 2018 (1 silver and 4 bronze) as we regularly see medal tables with gold medals taking up the top slots ie one gold medal would put you above teams with multiple medals (those pesky purists!).
I think the fairest way for me is the points system, its objective and based on this system we can also look at trends in more detail. There does seem to be a trend of improvement from 2016 onwards, in fact, may be looking in more detail we just had a number of ‘difficult years’ between 2007 – 2015 and really we’ve always been great in Great Britain!
Anyway, our best European championships since 2006 and a trend for continuous improvement over the last three European championships. We should be pleased with this and hope a similar trend is seen at world level in Baku 2018 and Tokyo 2019 over the next two years and of course at the Tokyo 2020 Olympic games.

A recent research paper by Ritchie et al., (2017) entitled “Where science meets practice: Olympic coaches’ crafting of the taper process” has supported a long held belief of mine that performance coaching is about science being applied artistically; in other words we apply scientific principles and knowledge to situations that are complex and human in nature. Ritchie et al., (2017) discuss the taper process and acknowledge previous research in this area that considers different models such a linear, stepped etc. The basic concept is to maintain performance by lowering volume and maintaining intensity and frequency. Ritchie et al., interviewed seven performance coaches in track and field, one of the key findings was that these experienced coaches had developed the scientific principles to deliver a taper but there was much more to the taper than just applying the science. Adapting the plan constantly, monitoring the process and collaborating with the athletes were almost more important in the taper.
For this years British championships I worked closely with two athletes. These athletes had a three week overload period prior to a two week taper. The overload period was hard and included two competitions, one of which was international, a week long training camp and a weekend of national squad training embedded within their normal training programme. Coaches normally plan the taper prior and manage a linear, exponential or stepped type of decrease in performance. Based upon the work cited above I decided to choose a different approach.
We use a programme called athlete analyser to monitor the athletes training load. Athlete Analyser uses the work of Gabbett (2016) to monitor training load and the software produces a live graph. The aim of my taper was to increase performance by lowering fatigue without diminishing fitness, this means decreasing volume whilst maintaining intensity. Using the live graph and collaborating daily (sometimes twice daily) with the athletes I manipulated the taper. One of the graphs are shown below.
Both athletes reported feeling very well prepared for the competition and were confident going into the event.
This method is very time consuming, as a volunteer coach I would struggle to do this with more than 3-4 athletes. There is also the consideration of the athletes mental state in the overload period and the taper, coaches have to remember how the athletes are feeling and whilst listening to them sometimes be prepared to move on and complete the sessions you wanted to. Lastly, if you have set technical elements you want to cover in the taper, you may have to accept you cannot.
We should also remember there are some factors not recorded by the software yet, illness, fatigue from work, fatigue from travel etc
This is something I am going to be looking at in a lot more detail, any feedback is welcome! I think working closely with the athletes to apply this kind of science is the key to successful performance coaching.
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.
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.
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 –
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!
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 Coaching, 10(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 Sport, 15(1), 53-68.
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 email@example.com.
I thought I would just write a quick posted as I haven’t posted for a very long time. Team GB sent 12 players to Paris this weekend to fight in the Grand slam. I think hat firstly, sending 12 players is great, it is a definite step up from previous years.
In terms of performance, well this is the first time we have won medal since we moved to a centralised system around 2009. In fact out last medallist in the Paris Grand slam was Euan Burton in 2008. This time round Sally Conway won Bronze in the -70kg and Natalie Powell won Bronze when she beat Gemma Gibbons in the -78kg. This is a good result, two bronzes and a 5th.
Of course there is a long way to go, of the 12 players we sent most went out in the first or second fight and I think we should be pushing for most players to finish with at least 2-3 wins but if we look at where we have been for many years, think this is a great result and we should be very happy, also sometimes this is just judo, you can’t win them all and many of the players were more than capable of winning a medal on the right day.
There is of course a little controversy! Philip Awiti being disqualified for a leg grad during transition. I am not going to say anything about this now, I am going to try and write a post later this week.
So for now that’s it, I really just wanted to say well done congratulation to all those who medalled and just a shout out to all the GB judo community really. The next Open National Squad Training is in April and this is part of the final prep for the Europeans. If you’re a dan grade that competes then I think you should be there. Our athletes need to train hard with a variety of players, at the last ONST we had maybe about 150 players which is great but we should have more.
This post is about the observations myself and Glenn made during our trip to the world championships in Chelyabinsk. On the last day we sat in a cafe and discussed our observation and what we feel needs to be worked on within our training group (obviously some of these have not been included). Later that day we saw a blog post by Oon Yeoh that basically said pretty much exactly the same as what we had said, non-the-less here are our observations.
Without a doubt there were a lot of shido’s given out by players not understanding the edge rule or not being able to use the edge to their advantage. I think years ago players could hugely use the edge to their advantage and eventually this will start happening again. There has been cries by coaches and officials to “fight int he middle” and i personally think this is a little naive, what athletes should do is understand the rule and use it to gain advantages, this doesn’t necessarily mean by forcing shido, the edge is a powerful tool for gaining the correct reaction to throw your opponent.
There were a lot of ura-nage variations, this happened across both genders and all weight groups. There is no evidence as to why this is happening more frequently but my guess would be that because of the new rules players are turning in for an attack when slightly more compromised than before because it is hard to dominate with the kumi-kata but this is just a guess. Obviously there is also the removal of leg grabs and maybe techniques such as te-gurma might have been used before.
This was a very common technique, not really sure why but personally i think it is because of the new rules around kumi-kata and not being able to break the grip with two hands thus athletes are breaking the grip by turning in or have the sleeve already pinned.
A lot of the tradition kind of uchimata sukashi where the opponent avoids the uchimata and then steps across for a harai-goshi or tai-otoshi type technique. There was also a lot of what might be described as the “ride and roll” technique. I would argue this is possibly due tot he reasons outlined above.
Completing the armlock when the opponent stands up
Despite the rule changes allowing the application of a ne-waza technique once the defender has got to their feet and ippon rarely happened once they did. I feel this is generally because athletes hadn’t really figured out yet how to maintain the ne-waza or how to get the opponent back to the floor once they got to their feet rather than the referees not giving enough time. This was most obvious in kansetstu-waza and in particular juji-gatame.
Shido has pretty much always been the highest scoring technique in modern competitive judo and the rule changes do not seem to have changed this. Obviously there are now a lot more reasons to be given shido and some players have a great understanding of the “shido game’ and can really manipulate the contest. I would say possible the best player at this is Pavia (FRA) and this is not to say she doesn’t throw big, because she does! In fact i would argue she uses the shido game to make sure she can achieve the big throws.
Referees not as strict?
I am going to get some videos to highlight this point because i think it is very important. Although the referees are strict they are nowhere as strict as many of the referees in the UK, maybe somethings are simply missed but actually a lot of the time they basing their decisions on the philosophy of the rules rather than a black and white statement in the rule book. This is a big problem for us, we do not have referees operating at this higher level and therefore the manner in which the rules are being applied is not being filtered down to the national refereeing structure. This failure by British judo to get referees at this level is affecting the entire performance of judo in the UK and our international players often end up fighting a completely different type of contest here in the UK. The rules are about creating better judo not just using shido’s and hansoku-make all the time.
