The free throw is one of the most important shots in basketball. In fact, approximately 20% of all points scored in NCAA Division 1 come from free throws (Kozar, Vaughn, Lord, Whitfield and Dve 243-248). The importance of this shot increases later in the game, because free throws tend to comprise a greater percentage of points scored in the final 5 minutes than in the initial 35 minutes by both the winning and losing teams (Kozar et al., 123 - 129). The free throw is considered the easiest shot for a professional basketball player, as the player stands alone, 15 feet away from the basket, with no defenses or distractions. The player must prepare the target, load the ball and shoot (Okubo & Hubbard, 2006). A successful free throw requires deep concentration and, above all, good mechanics to make a perfect shot. Even though a free throw doesn't seem like an action that requires a lot of movement, the body's muscle groups and joints work together in isotonic contractions. , using multiple muscle groups in creating movement. A free throw engages the elbow, hip and ankle extensors in addition to the wrist and shoulder flexors. In the case of the knees, the joints are hinged and the movement begins with a flexion, preparing for the free throw. Quadriceps and hamstrings become the antagonist and agonist. This movement occurs when you use knee flexion so that the muscles work in pairs. The contraction of the hamstring pulls on the joints that cause individuals to bend their knees. The movement following flexion is knee extension. When the shooter releases the ball, the quadriceps is the agonist and the hamstring is the antagonist.
