In the figure below, Becky is initially in the rotation position as in the front view. Move the mouse over the figure to see the transition between these two stages.

During the transition, the body is stable and compact, and the arm is being controlled to prevent it from drifting too far outward under the influence of the rotation. It is clear that the path of the racquet is simple and compact and that there is minimal upper arm rotation. Most of the positioning of the racquet arises from the body rotating. In essence, paraphrasing the words of Chris Evert, the movement of the racquet ensures a "quiet racquet head." There is minimal variance in the racquet path. Notice that the elbow is nicely positioned in front of the body plane as a result of the previous stage and that the shift of body weight offsets the tendency of the racquet arm to fly outward during rotation. In this set of figures, Becky's arm is being used to sustain balance and stability and to counter the equal but opposite reaction. Caution: Develop this motion carefully. If you are stiff, you might strain a muscle by being too aggressive. Allow several weeks for full development. |
