The kinematic analysis of three taekwondo kicking movements.

[[abstract]]The purpose of this study was to compare and describe the kinematic characteristics of the lower limb joints of three kicking movements in Taekwondo. Five elite female athletes served as subjects in this study. Two Peak high-speed cameras (120Hz) were synchronized to record three kicking movements. The maximum foot velocity duration of movement and the minimum knee angle in these three kicking movements have significant differences. Back round-kick and Back-kick are not whip-like movements. As for the curve of foot velocity, there is twin peak in Back round-kick. It is also notably different from the other kicking movements
