        In order to examine the effects of hip strength training on upper extremity function and&#xD;
        performance, 60 healthy volleyball players with an age range of 13 to 40 years will be&#xD;
        included in our study. Shoulder joint range of motion, shoulder and hip muscle strength,&#xD;
        upper extremity functional performance, and spike speed will be evaluated. Participants will&#xD;
        be randomly divided into 2 groups as Training Group (TG) (will receive 6-week, 3 days a week,&#xD;
        hip strength training in addition to their sport-specific training) and Control Group (CG)&#xD;
        (will continue their sport-specific training).&#xD;
  &#xD;
        Evaluations will be repeated 3 times before exercise training, after 6 weeks of exercise&#xD;
        training, and at the 12th week, and the results will be analyzed.&#xD;

        60 volleyball players will be included in our study. Assessments: 1. In the evaluation of&#xD;
        upper extremity function and performance; strength of the shoulder internal and external&#xD;
        rotator muscles will be measured with a hand-held dynamometer, shoulder internal and external&#xD;
        rotation joint range of motion with a digital inclinometer, finally functional performance&#xD;
        with closed kinetic chain upper extremity stability test and spike speed with a speed gun. 2.&#xD;
        strength evaluation of the hip abductor, extensor, and external rotator muscles with a&#xD;
        hand-held dynamometer. Participants will be randomly divided into 2 groups of 30&#xD;
        participants. The Training Group (TG) will receive 6 weeks of hip abduction, extension, and&#xD;
        external rotation strengthening training in addition to their sport-specific training.&#xD;
        Strengthening exercises will be done 3 days a week and every other day with a&#xD;
        physiotherapist. Control Group (CG); will continue their sport-specific training. Evaluations&#xD;
        will be repeated 3 times (before exercise training, after 6 weeks of exercise training, and&#xD;
        at the end of the 12th week) and the results will be analyzed.&#xD;
