Major Muscles and Actions Involved
In the Triceps Push-Down the triceps brachii muscle is involved in elbow joint extension. In this action the forearm moves away from the upper arm, which is held stable, to a fairly straight, upright, arm position.
The sports uses are the same as for the triceps overhead press. In addition, the muscle strengthening in this exercise plays a major role in baseball batting (just prior to ball contact) and in the tennis serve, volleyball spike and basketball shooting. It is extremely important in the martial arts (karate, wrestling, and so on) and for boxers and mixed martial artists in punching. This is the action that produces up to one-third of the total force in a punch. Also, elbow extension is the key action for arm quickness in reaching.
