The aim of this study was to clarify the motions and mechanisms of changes in the posture of the kicking foot when kicking a launched ball toward different directions during soccer side-foot kicks. Ten male collegiate soccer players kicked the launched ball toward three targets 7 m away that were placed front of them with 30 degrees intervals. The pelvis showed different rotation through the ball impact between the target directions because the players turned their anterior pelvises toward the target direction. In contrast, there were no differences in the rotation of each joint of the kicking leg between the target directions. These results suggest that players kick the ball toward different directions by adjusting the posture of the pelvic rotation without largely changing the motion of each joint of the kicking leg.
