15 years and older elite overhead athletes (swim, tennis, basketball,volleyball) were included in the study.

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.

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

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.

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.

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.
