In this study, we investigated the way in which human control the take-off angles and the strength in counter movement jumps, using a high-speed video camera, a force platform and EMG recordings. Subjects were five university male athletes. The joint works and time integrals of EMG of the lower limbs were calculated. Close negative correlations 'were seen between the take-off angles and the hip joint work and between the take-off angles and the IEMG of the biceps femoris. This suggests that the forward propulsion needs the hip joint work and the activity of the biceps femoris. Close positive correlations were seen between the jump heights and the contribution of the hip joint work to the total work, and between the jump heights and the IEMG of the gluteus maximus. This suggests that the upward propulsion needs the hip joint work and the activity of the gluteus maximus.
