Brief summary
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.
Interventions
OTHERAssessment 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Medicine ball forward throw | From enrollment to the end of assessment for 1 day | 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 balanced test | From enrollment to the end of assessment for 1 day | 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. |
| Range of motion of internal and external rotation | From enrollment to the end of assessment for 1 day | 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. |
| Strength of Internal and External Rotator Muscles | From enrollment to the end of assessment for 1 day | 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. |
