Brief summary: Tennis is a sport where high performance, strokes and wide ranges of motion around the court must be created and high-strength movements are repeated repeatedly. Speed and control are important in terms of sportive performance during the serve throw in tennis. While these actions are taking place, a dynamic load that exceeds the physiological limits of the joint is placed on the shoulder. Disruption in the kinetic chain can cause injury to the shoulder. In this regard, the incidence of tennis injuries is approximately 21.5 injuries per 1000 training hours. The glenohumeral joint creates a wide range of motion for the shoulder and is also biomechanically related to the scapula. Scapular dyskinesia, the pathological position of the scapula, has been associated with common pathologies such as rotator cuff tears, labral tears, and shoulder impingement. Although there are studies with different opinions about the causality of scapular dyskinesia, the current literature has reported that scapular dyskinesia is indirectly associated with shoulder pain in overhead athletes. Achieving maximum shoulder performance in sports that require overhead activities such as tennis largely depends on the delicate balance between the scapula and the clavicle, humerus and rib cage joints. Tennis, which is an increasingly widespread sport in our country, exposes the shoulder joints to high stresses. If changes are not detected and necessary precautions are not taken, the shoulder structure may be at risk of injury. In the current literature review, no study was found that evaluated the relationship between scapular dyskinesia, shoulder mobility and serving speed in tennis players. The aim of our study is to evaluate the effects of scapular dyskinesia, glenohumeral joint mobility and posterior capsule tension on serving speed in tennis players. It is thought that the results to be obtained from our study will guide the creation of appropriate exercise programs in athlete training by determining the effects on sportive performance by determining the changes seen or to be seen in the shoulder complexes of tennis athletes.
