The aim of this page is to show the research I am doing in judo performance, what other research I am involved in and how this is beneficial to the judo community. I am currently a full-time member of staff at Anglia Ruskin University and therefore am expected to conduct research as part of my work.
PhD
I completed my PhD thesis in September 2017 and my viva in November 2017. The title of my thesis was “A time-motion, technical and tactical analysis of lightweight women’s judo.” The aims of the work were to:
* To develop an understanding of the technical aspects of lightweight women’s judo
* To develop an understanding of the tactical aspects of lightweight women’s judo
* To understand the physiological demands of lightweight women’s judo from a time-motion perspective
Some might ask why this is important. Well, in the UK, high-performance judo has a budget for London, Rio and the Tokyo Olympic cycles have been between approximately £7.5m – £7.9m per cycle of taxpayers money. For argument’s sake, lets say this is split 50/50 for men and women, that is almost £1m per year of taxpayers money to get a maximum of 7 Olympic medals. If we were spending this much taxpayers money on anything else you would expect the delivery system to be very well researched so why not judo?
Much of the currently available research is dated, it is based upon old weight groups and old rules. There is also little research that focusses on both men and women and virtually none that is solely on women.
Developing an understanding of how women’s judo is different from men’s can inform coaches of how best to train female judo players.
