Anterior glenohumeral instability is a condition which may plague athletes of any sport. It can be produced by an acute shoulder trauma such as a dislocation or it may develop slowly during overhead activities such as swimming. There are special implications with how the unstable shoulder should be used in the weight room. ... At the extreme of any shoulder motion, the capsular ligaments are stressed. ... When trauma stretches the capsular ligaments, the rotator cuff muscles must continually be active in controlling the amount of excursion between the articulating surfaces, otherwise instability may ensue. Instability is characterized by excursion outside of the normal physiological motion (subluxation or dislocation) producing pain and apprehension. Glenohumeral instability may also contribute to other shoulder pathologies such as rotator cuff tendinitis and impingement syndrome.
The most common instability of the shoulder is in the anterior direction. ... For the person with an anterior instability, any exercise that positions the arm in this manner puts the athlete at risk for a subluxation. ... Lifting weights overhead poses a major hazard for the athlete with glenohumeral instability. Besides the shoulder being in an unstable position, we are overloading the muscles until they are fatigued.
