Among tennis strokes (serve, forehand and backhand) the tennis serve has been examined the most as it produces the largest stress on the shoulder and lower back. This stress can result in overuse injuries. The serve is also a highly complex stroke because of the use of multiple body segments to produce power through properly timed rotations and complex coordinated muscular activations. The serve requires strategic pinpoint accuracy and coordination of body segments, known as the kinetic chain. This chain links the generation, summation, transfer, and regulation of forces from the legs to the hand (Fernandez 2013). Research has suggested increasing serve performance occurs with increasing muscle strength of the entire kinetic chain without affecting serve accuracy (Fernandez 2013).
