BACKGROUND: In previous biomechanics studies on triple Jump, constructed by hop, step and jump, have not revealed the joint power in lower limb in these three jumps at a time. The purpose of the present study was to clarify the characteristics of joint power of the three lower limb in support period. METHODS' Subjects were six male athletes triple jumpers. They tried triple jump with maximal effort outdoor, and their jumping motions were videotaped using 3D motion capture device (200Hz). RESULT: The joint power output in the lower limb has showed a common pattern in the support phases in three jumps. The work in knee joint was especially more negative than that in other joints. It was suggested that eccentric contractions in each of the support period. There was no significant correlation relationship between touchdown angle and work in step and jump phase.
