The purpose of this study is to investigate the effect on jumping motion in changing takeoff-angle. The subjects were two male university students (23yrs, 179.0cm, 74.8kg and 21yrs, 169.3cm, 66kg). They performed vertical jump and three kinds of takeoff-angle standing long jumps on a force platform. The motion is simultaneously recorded by a High speed camera (125fps). The results are as follows. The ankle joint angle is same in jumping motion between both subjects and every different takeoff-angle. The knee joint angle is different between subjects. Subject A changed the max flexion time in jumping motion, but subject B didn't change. As the subject jump lower, the knee joint torque is smaller, and the hip joint torque is larger. To change takeoff-angle, Subject A adjusts the timing of joint flexion, but subject B adjusts the different way from subject A.
