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.

Inclusion Criteria:

• elite swimmers

Exclusion Criteria:

• shoulder surgery
• dislocation

Swimmers from the winter national trials who competed at state, national or international level, performed at least five swim sessions per week and intended to continue this training level during the following 24 months were eligible to participate in this study.
