Not sure if i can explain it but look at that video of rafa hitting;
After the racquet drops, he moves his torso and first the racquets stops the motion, then it goes back with the lag that body turn creates, and lastly go forward to hit the ball. That means all the momentum that created with a loop takeback is destroyed just before hitting the ball and a loop takeback has no difference compared to a straight one in the words of power and racquet head speed. Can somebody explain me that situation ??
No the momentum is not destroyed as you put it. The racquet movement never really stops moving -- the motion is not discontinuous -- the racquet head drop is translated/converted into other actions of the forearm (rotation), arm and other body parts. The momentum is used to quickly change the orientation of the racquet and the direction of its motion. Look at the sequence more carefully and you should be able to pick up these actions/interactions.
