Re: Good for golf - Good for baseball ??

Dear Jack

It should be said that your insites are always interesting and informative however on this we shall see. Principals of rotation of the swung object the effect of the lead foot rotation is due to the angular rotation of the object in a more horizontal plane in baseball then in golf. Not too many golfers hit a ball off a tee that is 3 feet high because if they did then the foot would open up in order to finish the rotation around the horizontal plane.

The lower body movement of a golfer and a baseball player follow the exact same biomenchanical principal of kitematic sequencing. I quote "During the forward swing of all body segments, including the pelvis, upper body, arms and bat/club must accelerate and decelerate in the correct sequence with specific timing, in order to most efficiently transfer energy and accelerate each of the following body segment. In addition to transfering energy across a joint, energy is added by the muscles across that joint. If the timing is wrond the engergy (speed) will be lost.... The correct sequence during the forward swing requires the pelvis to speed up, peak first, then slow down, followed by the upper torso, then the arms and finally the bat/club."

The legs/big muscles lead the swing in golf and baseball. The swing plane of the upperbody and arms determine how and where the feet will finish.

I would encourage any thoughts on these comments
