The purpose of this study is to investigate the joint movement of the lower legs and the velocity of the ball in an instep kick made as powerful as possible. Subjects were 8 male students who were skilled members of the high school soccer club, including 2 members from Aichi Prefecture. In this study, the velocity of the ball both the kicking leg and the supporting legs the variation of the hip, knee and ankle of angle were analyzed using a high-speed video camera operated at 200 fps during the kicking. The results were as follows. (1) The mean velocity of the ball obtained from these subjects (29.3±1. 1m/s) was significantly higher than that of other high school players. (2) The range of the hip, knee and ankle angle showed little variations in the following phases. In the phase from the foot released until planted, the degree of variation of the hip and knee in the kicking leg and hip in the supporting leg was little. In the phase from the foot landing until the foot impacted the ball, the range of the angle variation of the hip, knee and ankle in the supporting leg was little. In the phase from the foot impacting the ball to when the follow-swing reached the maximum level, the range of the angle variation of the hip and knee in the kicking leg and of the hip in the supporting leg was also small. (3) The hip of the kicking leg started to flex from the foot release until it landed. The hip of the supporting leg started to extend about the same time. In other words, the joint movement of the hip was antithetical, where as the joint movement of the knee and ankle were not. In particular, by keeping the knee of the supporting leg fixed, the knee of the kicking leg started to extend.
