The purpose of this study was to clarify the relationship between acceleration and maximum sprinting ability, performance in various jumping tasks, and maximum leg strength in adolescent students. Sprinting ability was evaluated in terms of 50m sprinting velocity. The jumping tasks used for performance measurement included Standing five jump, Standing triple jump, Standing long jump, Counter movement jump and Rebound jump. Maximum leg strength was measured using isometric squats in which the angle of the knee was 135 deg. The results demonstrated that students with superior sprinting ability also showed high performance in the various jumping tasks and also had higher maximum leg strength. Among the various factors that affect sprinting ability, performance in one-leg alternation jumping, performance in jumping with both legs simultaneously, and leg strength were shown to have a high correlation in that order. In addition, the influence of both legs in the simultaneous jumping task and leg strength were considered to make a large contribution to acceleration sprinting ability. Similarly, the influence of one-leg alternation jumping performance was considered to make a large contribution to maximum sprinting ability. The findings of this study are considered useful for application to health and physical education classes.
