Effects of Hip Strengthening Training in Volleyball Players

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

Evaluations will be repeated 3 times before exercise training, after 6 weeks of exercise training, and at the 12th week, and the results will be analyzed.

About this study

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

Treatment and study plan

Training group

Other

Hip strengthening exercises will be performed 3 times a week for 6 weeks in the training group. 3 exercises consisting of 2 sets and 10 repetitions will be performed every week. A rest interval will be given between sets.

Primary outcomes

  1. Shoulder strength

    Time frame: Baseline, 6 weeks later and 12 weeks later

    Change of shoulder internal rotation and external rotation strength(in kg, with hand held dynamometer)

  2. Upper extremity functional performance

    Time frame: Baseline, 6 weeks later and 12 weeks later

    Determine the performance with Upper Extremity Closed Kinetic Chain Stabilization Test (number of touches)

  3. Spike speed

    Time frame: Baseline, 6 weeks later and 12 weeks later

    Determine the performance with Spike Speed Test(in km/h, with radar gun)

Secondary outcomes

  1. Shoulder range of motion

    Time frame: Baseline, 6 weeks later and 12 weeks later

    Change of shoulder internal and external rotation range of motion(in degree, with inclinometer)

  2. Hip strength

    Time frame: Baseline, 6 weeks later and 12 weeks later

    Change of hip abduction, extension, and external rotation strength(in kg, with hand held dynamometer)
