    We aimed to illustrate the influence of kick directions on soccer instep kicking kinematics. Nine male soccer players performed maximum instep kick towards three angled directions (15, 45 and 75 degrees) based on their approach run pathway. The motions were captured using 4 highspeed video cameras at 250 Hz. The selected kinematic parameters concerning the ball, both legs and pelvis were calculated. The absolute ball velocity was significantly lower in 75 degrees condition than in the other conditions. That was induced by a significantly reduced foot velocity component towards the target direction while the kicking directions had no significant effects on the absolute foot velocity. The peak angular velocity of the pelvis rotation increased systematically with the kicking angles and moderately correlated (r=0.52) with the peak angular velocity of the hip internal rotation of the support leg. This might explain that the hip joint motion has some dominant role for the pelvis rotation required in angled kicking. For the kicking leg, there also observed a remarkable motion to align the direction of swing plane with the target direction. There was a robust correlation (r=0.88) between the angular velocity of the swing plane rotation and the hip internal rotation at the ball impact. It was reasonable to assume that the hip internal rotation most likely regulate the swing plane of the kicking leg depending on kicking angles.
