In your opinion, would a rear view be as effective concerning the three areas you mentioned above ? (If you were using ML camera shots then they have the high powered zoom from CF for a front view. When videoing game swings on a personal level a rear view angle would be more feasible in most situations.)

Did you find that the shoulders are parallel with the lead arm at every extreme of the strike zone when establishing the swing plane ? <<<

Hi Terry

Sorry for the delay in replying to your post but I have been real busy the past few days. – I did not use a rear view of the swing in my study, but I see no reason why it would not be useful once the viewer become orientated with it.

No, the plane of shoulder rotation usually was not inline with the plane of the swing. For one thing, most batters have close to the same shoulder plane for high and low pitches. Batters who were more crouched over in their stance had swing planes more inline with the swing plane than did players with a more erect stance.

Terry, in the clip of A-Rod, he appears to have some irregular motion in his hand-path on that swing. If you look carefully at frames 11, 12 & 13, the blur (for lack of a better term) and slight dip in the hand-path may indicate some wrist bind. I am not sure to what degree as the bat is not clear with the dark background. – This may be just a one swing fluke. But I noted in the side view (different swing I think) that his bat may have also dipped slightly in frames 12 & 13. --- In the study, I charted 15 swings (clear frames) of a player before classifying his mechanics.
