Although overhead sports have different characteristics, the movements in the shoulder and upper extremity are similar. These sports may involve a combination of symmetrical, asymmetrical, bilateral and unilateral movements. In sports involving asymmetric movements, biomechanical changes are observed in that area due to the use of the dominant extremity. One of the reliable methods to reveal the stress effects caused by biomechanical stresses is to determine limb asymmetries. Considering the literature, limb asymmetries may be related to injury and performance.

Exclusion Criteria:
15 years and older elite overhead athletes (swim, tennis, basketball,volleyball) were included in the study.
Other: Assessment of overhead athletes
Assessment of medicine ball forward throw, Y balance test, Range of motion of the shoulder (internal and external rotation), strength of internal and external rotator muscles.
Medicine ball forward throw
The medicine ball forward throwing test is used to determine anaerobic power in athletes. The farthest distance the medicine ball is thrown from the starting position is recorded
Time frame: From enrollment to the end of assessment for 1 day
Y balanced test
Y balance test for the upper extremity is a test that evaluates the performance of the extremities and core balance. While one hand is fixed on the platform, the other hand tries to reach in the anterior, posterolateral and posteromedial directions. The furthest distance reached is recorded. The test is repeated for both extremities.
Time frame: From enrollment to the end of assessment for 1 day
Range of motion of internal and external rotation
While the athletes lie on their back, the shoulder is abducted at 90 degrees and the elbow is flexed at 90 degrees, internal and external rotation degrees are measured using a universal goniometer.
Time frame: From enrollment to the end of assessment for 1 day
Strength of Internal and External Rotator Muscles
While the athletes are lying on their back, with the shoulder in 90 degrees of abduction and the elbow in 90 degrees of flexion, internal and external rotation degrees are measured using the Commander Powertrack II dynamometer.
Time frame: From enrollment to the end of assessment for 1 day

Ran from Dec 2023 to primary completion in Mar 2024, 3 months.
Of 119 non-industry interventional studies with no phase under Athletic Injuries, half reached primary completion within 5 months of starting (the median), counting those still running; a quarter within 2 and three quarters within 14. This study's 3 months is below that.
Counting every sponsor, half of 121 studies reached it within 5 months; a quarter within 2 and three quarters within 14.
