Relation Between Swimming Stroke Types and Shoulder Movement in Young Competitive Swimmers

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This cross‑sectional study will enroll 80 healthy competitive swimmers aged 13–19, with 20 swimmers for each stroke group (freestyle, backstroke, breaststroke, butterfly). Participants must have at least 5 years of experience and at least 1 year of competition activity, with no major shoulder injury or surgery in the past 6 months. The study will examine scapular upward rotation and the strength of the serratus anterior, middle trapezius, and lower trapezius to see if stroke specialization relates to these measurements. Hypotheses focus on potential links between stroke type and scapular dyskinesis, muscle balance, and shoulder function under overhead loading conditions. The project emphasizes observational assessment of biomechanics in a real-world athletic population and does not include an intervention.
