The golf swing has been investigated mathematically with least mean square error method whether the club head can be swung in a single inclined plane. The recent findings suggest that the club head do not move exactly in a single plane because of the minor errors at the beginning of the downswing. The aims of this study were to verify when the club head begun to the regression plane during the downswing. Four professional golfers were participated and the swing movements with 5 iron were analyzed by three-dimensional analysis techniques. The results can be summarized as follows. The orthogonal distances from the regression plane to the center of the club head were shown between 0.055m and 0.112m above the plane at position 2. So the golf instructor"s assertion that the extended line of the shaft pointing the ball flight line at position 2 was not correct. The angles of the right elbow at the top the back swing were shown between 83.6˚ and 89.2˚ for the participants so that the golf instructor"s assertion with 90˚ at the top of the back swing was supported. The conclusion was that the motion of club head during the downswing was not fitted to a single plane.
