Comparing Shoulder Stretching and Percussive Massage on Shoulder Rotation and Attack Speed in Female Volleyball Players

Comparison of the Effects of Shoulder Stretching Exercise and Percussive Massage Treatment on Shoulder Rotation Movements and Attack Speed in Female Volleyball Players

This study aims to investigate the acute effects of PNF modified sleeper stretches and percussive massage treatment on shoulder rotation movements and attack speed in female volleyball players and compare these applications.

56 female volleyball players will randomized into 2 groups of 28 people each. In the evaluations conducted on the participants, rotational normal joint movements of the athletes will be measured using a digital inclinometer. The spike velocities of the athletes will be determined using a sports radar (Sports Radar 3300, Sports Electronics Inc, Washington, D.C. USA.). Participants will be randomly divided into two different groups consisting of 28 individuals each. The Proprioceptive Neuromuscular Facilitation Stretching Group (PNFG) participants will undergo one session of PNF posterior shoulder stretching exercise in the modified sleeper position. The Percussive Massage Treatment Group (PMTG) participants will receive a 5-minute massage on the posterior deltoid area. Evaluations will be repeated three times before the applications, immediately after, and 30 minutes post-application and the effects of different applications will be compared through analysis.
