The following effectual datas were obtained, from to analyze the simultaneous datas of take off motionn in the take off motion of two hurdlers. Subject KITAMURA 1. It was related to decrease horizontal speed by take off motion that great knee flexion of take off leg. 2. It is open to errors the imperfection take off motion of pushing ground by early shake out of leading leg. Subject ONO 1. The horizontal speed was great decrease by the brake motion of proping leg with body back position at the begining contact motion of take off. 2. It was related to decrease horizontal speed, because the decrease phase of horizontal speed became long by the great knee flexion of take off leg with lated swing up of leading leg in the take off. 3. It is open to errors "hip flexion posture" take off motion that the imperfection pushing ground with early shake out of leading leg and the excessive body forward position at the end of take off phase.
