Throwing / Pitching / Volleyball / H20 Polo

Micro tearing can form very easily with such high velocity sports. Accelerating the arm can lead to microtears and adhesions in the front of the shoulder. But even more common is injury to the muscles that slow down and stop the shoulder after the throwing movement. The rotator cuff muscles in the back of the shoulder are most commonly injured because of the tremendous amount of force that is exerted to decelerate the shoulder. These deceleration muscles are located on the back of the shoulder and contract while attempting to decelerate the arm immediately after the release of the ball. Anytime the shoulder is involved in high-speed activities any muscle, tendon, or capsule around the shoulder may be injured.
