M. S. KWON, S. H. SHIN. A Study of the Ankle Joint to Mechanical Energy in Crouching Start According to the Backward Block Inclined Angle Increase. Korean Journal of Sport Biomechanics, Vol. 15, No. 1, pp. 19-28, 2005. The purpose of this study was to improve the ankle joint to mechanical energy in Crouching start according to the backward block inclined angle(F, F(+1), F(+2)) increase. For purpose of this study the ankle joint was considered as a single hinge joint rotation about a transverse axis. A two-dimensional(sagittal plane) analysis was performed on data collected from 3 spriters(unversity student). During Crouching start, the ankle joint moment showed a similar patterns according to the backward block inclined angle increase. The peak values of ankle joint moment was plantar flexion approximately 80% throughout the contact phase for Crouching start. The absorbed and generated energy represented different values from the backward block inclined angle increase at ankle joint. On the backward block inclined angle F, subject A(55？ and C(50？ produced energy generation more than other block inclined angles. On the backward block inclined angle F(+2), subject B(50？ showed largest energy generation.
