Effect of Two Preventive Exercise Programs for Swimmer's Shoulder on the Torque of Shoulder Rotator Muscles in Competitive Swimmers

Not Applicable

Completed

• Conditions: Shoulder Pain; Injury;Sports; Sports Physical Therapy
• Interventions: Other: 12-weeks weight prevention program; Other: 12-weeks elastic band prevention program; Other: sham intervention

• Registration Number: NCT06552585
• Lead Sponsor: School of Allied Health Sciences of Porto (ESTSP) - Polytechnic Institute of Porto (IPP)

Brief Summary

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

Primary Outcome Measures

Name	Time	Method
Peak torque	12 weeks	The concentric and eccentric peak torque of internal and external rotators of the dominant and non-dominant shoulders at 60°/s, 120°/s and 180°/s, evaluated through an isokinetic dynamometer Biodex System 3 (Biodex Medical Systems, New York).

Secondary Outcome Measures

Name	Time	Method
Time to peak torque	12 weeks	The time between the beginning of the torque caption and the peak torque previously described.
Conventional concentric external/internal shoulder rotators ratio	12 weeks	The quotient between peak torque values of the concentric external and internal rotators of the shoulder multiplied by 100.
Functional eccentric external/concentric internal shoulder rotators ratio	12 weeks	The quotient between peak torque values of the eccentric external rotators of the shoulder and concentric internal rotators of the shoulder multiplied by 100.
