The objective of this study was to examine the validity of the theoretical equations of ball velocity and ball rotation in side-foot soccer kicking. Five experienced male university soccer players performed side-foot kicks using a one-step approach for various attack angles and impact points. The kicking motions were captured three-dimensionally by two ultra-high-speed cameras at 2,500fps. The influences of the attack angle and the impact point on ball velocity and ball rotation were obtained experimentally. The theoretical equations of the ball velocity and the ball rotation were derived based on the impact dynamic theory. Using the theoretical equations, influences of the attack angle and the impact point on ball velocity and ball rotation were obtained theoretically. From the experimental and theoretical results, it was suggested that the theoretical equations were valid. These equations enabled theoretical study of factors affecting the ball behavior.
