how does power transfer (better) from delaying when the foot down , in the overhead backhand clear? (vs not delaying when the foot comes down, and just having the foot down before the stroke starts) I have heard that if the foot is down before the stroke begins, then there is less power, than if the foot comes down during the time that the arm comes up. But what is the reason for that? What exactly is going on how is the power transferring from the foot? I understand more in the case of a forehand clear if a person does it by stretching up, (from foot rather than hips so much), then there's very much a line from the foot up the leg through the hip to the shoulder through the arm to the hand. But I dont really see how delaying the foot, to during when the arm comes up, helps the power.. I was speaking to a very good player recently and they said it certainly helps though they weren't sure why.
