ABSTRACT
This chapter uses a high-speed video camera system to investigate player technique during a knuckle shot. It describes the impact phase and other technical aspects of the knuckle shot in soccer. The chapter explains the kicking technique of a knuckle ball by analyzing leg motion and the subsequent phase of impact between the foot and ball. It dissects the technical aspects underlying a successful knuckle shot in soccer. One of the main findings of this study was that the angle of attack in the knuckle shot was smaller than that in the other shots. This result was anticipated, considering that reduced angle of attack between the face and swing vectors at the impact surface and primarily translational motions at ball impact are fundamental technical aspects of the knuckle shot.
