After being informed about the study, all swimmers giving written informed consent will undergo a 1- week screening period to determine eligibility for study entry. Swimmers who meet the eligibility requirements will be evaluated 3 times: pre-season, mid-season, and post-season.
The aim of this study is to investigate the effect of a competition season on shoulder periarticular structures, muscle strength, muscle endurance, joint range of motion and upper extremity performance in young swimmers.
