Volleyball is a very popular sport worldwide, and both the indoor and outdoor versions are played at the Olympics. The several different positions have unique associated injuries. Some positions require fast movements and reflexes; others require strength and power. Given the repetitive jumping and shoulder movements, some of the positions are susceptible to chronic overuse injuries. Others are related to landing awkwardly or taking powerful hits/blocks from the ball.
