The Effectiveness of a Static Passive Stretching on Glenohumeral Rotation Range of Movement in Elite Swimmers After Competition: A Quasi-experimental Clinical Trial

Shoulder injury is a common problem of overhead athletes, as swimmers. It's reported a reduction of side-to-side glenohumeral rotation from 11 to 18 degrees can increase 1.9 points the injury risk, because an alteration in biomechanics can turn lead to clinical findings of impingement and labral pathology. Posterior deltoid is a main muscle for propulsion in swimming stroke. To our knowledge, it isn't known how a posterior deltoid static passive stretch could reduce glenohumeral rotation restriction after swimming competition.
