Abstract
OBJECTIVE: To compare lateral rotator (LR) and medial rotator (MR) muscle strength of both shoulders in a sport involving asymmetrical movements (tennis), symmetrical movements (swimming), and symmetrical and asymmetrical movements (volley-ball). MATERIALS AND METHODS: Retrospective study of 42 healthy elite athletes (18 women: 14 tennis players, 19 swimmers and 9 volleyball players. We evaluated the strength of LR and MR of both shoulders by Cybex Norm isokinetic dynamometer, in the concentric mode, in the modified Davies position, at 2 different speeds (60 degrees and 180 degrees s(-1)) and analysed peak torque of LR and MR and LR/MR ratios. RESULTS: TENNIS: The MR peak torque of the dominant shoulder was significantly higher than that of the non-dominant shoulder. The LR/MR ratio of the dominant shoulder was significantly lower than the non dominant shoulder in women. SWIMMING: The LR strength and LR/MR ratio of the dominant shoulder was higher than the non dominant side in men at 60 degrees/second. Both shoulders showed comparable strength in women. VOLLEYBALL: Shoulder muscular strength was symmetrical. CONCLUSION: The higher strength of MR muscles in the dominant shoulder of tennis players (asymmetrical movements) has been reported in the literature. Athletes show asymmetrical shoulder strength in swimming, a symmetrical sport and similar LR and MR strength in both shoulders in volleyball, a sport with asymmetrical movements. To our knowledge, these results have never been reported before.
