Can someone please tell me what role does the elbow do in the forehand backswing? Some pros have a quite high elbow take backs and other pros not. For example, Pete sampras, Andy Roddick, Fernando Gonzales have a high elbow takeback while Roger Federer and Rafael Nadal not. Does it matter how high you raise the elbow on your forehand takeback.?? Is there any advantages or disadvantages in the backwing.?? Is it fundametally correct doing it?? One thing i can think of is that, it could help someone who has a stiff backswing let it have more rhythm and speed as the backwing can be more fluid.
