The purpose of this study was to determine the effect of leg training, while clarifying the characteristics of the muscular strength of a knee joint for university judo players. The subjects were 20 players belonging to the judo club of university. The subjects were classifiedinto training group (A) and control group (B). The training group performed resistance training and DEPUSU jump centering on the leg twice a week over seven weeks. The muscular strength of the knee joint was measured under the isokinetic contraction, and was analyzed at judo matches before and after training. The characteristic of the muscular strength of the knee joint, between peak torque (PT) and weight was in significant positive correlation, but that between peak torque/body weight (PT/BW) was in significant negative correlation.The muscular strength of the knee joint of group a increased significantly after training. Concerning the rate of the increasing muscular strength of the knee joint, significant differences between group a and group b were admitted for part of the velocity of degree. Concerning the analysis of a judo match,there was tendency for the leg technique of B Rank to increase after training with group a. These results suggest that, although the leg training was useful in the reinforcement of the muscular strength of the knee joint, it was thought that further examination was needed for improvement in performances.
