The traditional Nage waza skill such as Ippon seoinage is one of the most important skills in judo,which players exercise most,apply most and apt to score easily.In these years,our players’ nage waza skill have been largely improved,the gap between us and the world’s high skill even exist.There are few researches focused on the skill of judo,and our study choose 8 outstand judo players from athletics school of Beijing Sport University as our research object,using sEMG,combining with theory of sports anatomy to analyze and evaluate the Osoto gari of 8 outstand judo players in judo.According to the research,we get these conclusions:(1) The two side rectus abdominisp,the bliquus externus abdominis、biceps brachii、triceps brachii、gluteus maximus、biceps femoris、inside gastrocnemius of the right body,and back part of detoid、gluteus maximus、rectus femoris of the left body play more important role in Osoto gari.Athletes should strengthen the muscles above the practice in training in the future.(2) The speed and the rate of outstanding groups are bigger than general groups,for example:In the the left leg striding stage and the right leg forward swinging stage,the range of left arm pulling backward opponent’s body and the right hand grasping opponent’s left collar upwardly of the outstanding athletes is bigger than the general athletes, in this stage the better athletes’ s body touch with the opponent’s body closer than the general athletes.
