Brief summary

Background: To compare the pre-season clinical measures with shoulder rotator strength and range of motion between bilateral (swimmers) and unilateral (badminton players) overhead athletes. Design: Prospective cohort study Participants: 42 athletes were enrolled including 24 elite badminton players and 18 elite swimmers Independent variables: A pre-season visit consisted in clinical and isokinetic shoulder strength testing. Clinical testing consisted in the shoulder range of motion (ROM) measurements aIsokinetic internal and external rotator shoulder muscles strength was tested at 60. Conventional and functional (eccentric-to-concentric) ratios (FR) were calculated.

Interventions
