      <textblock>
        Volleyball is an interval sport involving consecutive aerobic and anaerobic loads. Strength&#xD;
        training based on explosive movements can improve performance in the upper extremities.&#xD;
        Strength performance has an important place in this sport. Trunk stabilization is defined as&#xD;
        'proximal stability for distal mobility'. Disorder in any segment of the kinetic chain model&#xD;
        will affect the quality of movement in the lower and upper segments.The aim of this study is&#xD;
        to examine the relationship between the morphological features of the transversus abdominis,&#xD;
        lumbal multifidus (L4-5), internal external oblique muscles, and the anaerobic power of the&#xD;
        upper extremity and shoulder girdle functionThis study was designed as a cross-sectional.&#xD;
        They will consist of 30 volleyball players between 14-30 years of age. Muscle morphological&#xD;
        features of the participants by ultrasound; explosive strength will be evaluated by Medicine&#xD;
        Ball Throw test, functional evaluation will be evaluated by Closed Kinetic Chain Upper&#xD;
        Extremity Endurance test.&#xD;
