A Time-Motion Analysis of Lightweight Women's Judo in the 2010 World Championships

Abstract

The Olympic sport of judo has a growing base of performance analysis research considering the technical aspects, the tactical aspects and time motion analysis. This study aimed to further analyse this sport by specifically considering the time motion aspects of work, rest, kumi-kata and ne-waza in lightweight women's judo to establish if there are differences in this specific population of judo athletes. Pre-recorded footage of the women's u48kg, u52kg and u57kg weight divisions (143 contests) from the 2010 world judo championships were coded into temporal sequences. The coding of five KPIs across the three weight groups produced a total of 1756 hajime to matte blocks (work), 1422 matte to hajime blocks (rest), 1786 kumi-kata sequences (gripping sequences), and 516 ne-waza sequences (ground work). The results suggest the time spent in hajime to matte (work) and in matte to hajime (rest) are similar to those seen in other studies. This suggests there is little difference in the work to rest segments for lightweight women's judo compared to heavier weights and males.

“…This is confirmed by the analysis of the scientific literature devoted to various aspects of judo training and competitive activity (Osipov, Kudryavtsev, Iermakov, et al, 2017;Peset, Ferrer-Sapena, Villamón, et al, 2013). According to their scientific works, experts argue that the significant growth of sportsmanship of martial artists and the development of sports science make it absolutely necessary to conduct comprehensive scientific research in judo in order to improve the performance of athletes' competitive achievements (Challis, Scruton, Cole, et al, 2015). What is more the experts note that high competitiveness in judo today according to the experts' opinions requires high-intensity technical actions from athletes which require the optimal physical condition (Torres-Luque, Hernandez-Garcia, Escobar-Molina, et al, 2016;Zaggelidis, Mavrovvouniotis, Argyriadou, et al, 2013).…”

“…These requirements apply to the judo, training and competition preparation which are in need of significant changes (Bocioaca, 2014;Peset, Ferrer-Sapena, & Aleixandre-Benavent, 2013). In the scientific literature there are many works related to various aspects of the preparation of judo fighters in competitive activityHowever, experts believe that the increase of sportsmanship of athletes and the development of the scientific base dictate the need for further research in the field of combat sports (Pryimakov, Iermakov, & Juchno, 2016), and especially judo (Challis, Scruton, & Pierantozzi, 2015).…”
