About this study
Official title: Upper Extremity Asymmetries in Overhead Athletes: Relationship With Injury and Performance
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Assessment of overhead athletesOther
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.
| Study group | Role | What they receive |
|---|---|---|
| Athletes in overhead sports | Experimental | 15 years and older elite overhead athletes (swim, tennis, basketball,volleyball) were included in the study. Receives: Other: Assessment of overhead athletes |
What is being measured
The primary outcome is the main question the study is designed to answer.
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
Measured: 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.
Measured: 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.
Measured: 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.
Measured: From enrollment to the end of assessment for 1 day
