Really cool 3D capture set up. However, I submit that the first expert makes quite a number of erroneous scientific statements. For example, he states that any lateral movement of the center of mass would be bad, that only rotation of the hips creates speed. If this were true, you would see many baseball pitchers successful striding towards first base as they pitched 90 mph or more. Never has this been the case.
@Inmotion70 Neither of the experts actually said what you claim . The first expert says that amateurs typically move laterally into their right side (aka sway) while Jamie rotates his hips behind him. However, he definitely sets his mass into the inside of his right leg on the backswing. Also, we can learn alot about rotational movement with baseball pitchers but pitchers aren't hitting something that is sitting still so they can move laterally all they want.
@Inmotion70 You don't know what you're talking about. The expert is in fact scientifically correct as the "most efficient" & speed producing means is rotational starting with the forward knee, then hips, shoulders, so forth. A pitcher uses precisely the same sequence but strides toward the plate for accuracy. The kinematic sequence is virtually identical accross all sports 'cause it's the way the human being moves.
