Study population: In this study, volunteer swimmers who practice swimming professionally in Ankara University Sports Club will be evaluated and included in the study. In determining the sample size of the study, Tate et al. Data showing the difference in shoulder joint range of motion were used. As a result of the power analysis, it was determined that 23 participants should be included in such a way that the type 1 error was 5% and the power of the study was at least 95%. Considering the possibility of participants leaving the study during the study period, 30 swimmers were planned to be included in the study. Posthoc power analysis will be done with the data to be obtained after the study.

Brief summary: 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.

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:

* To be between the ages of 10-15
* At least 6 hours of swimming training per week,
* Individuals do not have cooperation and communication problems,
* Individuals volunteer to participate in the study.

Exclusion Criteria:

* Previous upper extremity surgery,
* Experienced upper extremity pain at least 2 times in the past,
* Not attending training regularly for any reason.
