The evolution of the forehand: huge changes in angular momentum and torso rotation. How has the forehand evolved in the modern game? In this article, we’ll take a look at some of the components, including momentum, torso rotation, and the use of the legs both for loading and recovery. Momentum One of the biggest changes in the modern game has been in the increased use of angular momentum. In the history of tennis, good forehands have always been hit with two kinds of momentum. Linear momentum, which is generated in a straight line, and angular momentum, which is generated by rotation on an axis. Both types of momentum are working simultaneously in a good forehand. But we typically associate linear momentum with components such as stepping forward into the line of the shot, and swinging the racket outward toward the target. Linear momentum associated with stepping in and hitting through the line of the shot. Angular momentum, on the other hand, is associated with the rotation of the body core and the racket arm around the axis of the spine. This is where we see the big change in the modern game. The players today are currently using up to…
