Perform training exercises bilaterally to achieve muscular balance. One area unique to the two-handed backhand is the use of the non-dominant arm and wrist. University of Pennsylvania physics professor Howard Brody has identified two key tactics: Strike the ball as high off the ground as possible or give the ball more topspin, which creates an area of low pressure beneath the ball (a phenomenon known as the Magnus effect) to make it nose-dive into the service court.

Many of the muscle actions in the lower body are similar for all of the tennis strokes. Site of bone elongation and growth B. Eight digital cameras (Motion Analysis; Santa Rosa, CA; sampling frequency = 500 Hz) were used to record the three-dimensional (3D) trajectories of the 15 markers during the tennis serve. A pioneer study recently described the scapular motion during the cocking phase of the tennis serve (17). A first limitation of this study lies in the sample players, not allowing the application of our results to the tennis players at other skill level, sex, or age. Each body position requires different lower- and upper-body mechanics, although all three stances use a combination of angular and linear momentum to power the stroke. Rotation - this is where the limb moves in a circular movement around a fixed joint towards or away from the midline of the body. Analysis of, 4. During the forward swing (Figure 1.7b), concentric and eccentric contractions of the gastrocnemius, soleus, quadriceps, gluteals and hip rotators drive the lower body and hip rotation.
