Alright, so we all know tennis technique is changing. Modern technique says to use core rotation (angular momentum) to get power. The idea is that stepping into the ball was used simply to create forward momentum and that this is not applicable to today's game. However, I think stepping into the ball plays a larger role than just creating linear momentum. It seems to me, that the forward step is used to initiate the kinetic chain. That is, it triggers the angular momentum that is important to modern strokes. There are other methods of starting the kinetic chain like simply rotating the torso and pushing straight up off the ground, but these strategies feel way less natural to me. If you look at baseball pitchers and hitters, they all begin their kinetic chains with a step. That seems like a good indication that it's a good way to create power. So, what do you guys think? Can the forward step be part of the modern stroke?
