简要总结
The purpose of this study was to verify the effectiveness of two 12-week preventive exercise programs for swimmer's shoulder with monitoring and progression over time, on the peak torque and respective conventional concentric ratio and functional ratio. One of these programs was performed with weights and the other with an elastic band. This study hypothesized that the two preventive exercise programs minimize shoulder rotators imbalanced during the swimming season. The study design is a care provider and participants blinded, parallel, randomized controlled trial
