Seasonal changes in glenohumeral joint isokinetic strength in professional rugby league players.

Objective: To assess glenohumeral joint (GHJ) rotation strength across a rugby league season, since strength of rotator cuff musculature may protect against contact injuries to the shoulder.

Design: A prospective cohort study was used to compare GHJ rotation pre-, in-, and post-season.

Setting: Laboratory.
