This study aims to evaluate the effects of percussive therapy on muscle flexibility, balance, and jump performance in licensed U19 football players and sedentary healthy males under 19. Percussive therapy will be applied to the hamstring muscles for 120 seconds. Flexibility, balance, and explosive strength will be assessed using the sit-and-reach test, Y-Balance Test, and vertical jump test, respectively. The study also aims to compare the therapy's effects between active and sedentary participants.
This study investigates the effects of 120-second percussive therapy applied to the hamstring muscles on flexibility, balance, and jump performance in two distinct groups: licensed U19 football players and sedentary healthy males under the age of 19. The intervention will be delivered using a handheld massage gun device, and outcomes will be evaluated using the sit-and-reach test (flexibility), the Y-Balance Test (dynamic balance), and the My Jump Lab mobile app (jump performance). Pre- and post-intervention assessments will be compared within each group, and the results will also be analyzed to identify any differences in response between the active and sedentary participants.

Percussive therapy will be administered using the "Hypervolt Go 2 Black," a massage gun commonly used in clinical and athletic settings. Participants will lie in a prone position on a treatment table. To promote hamstring muscle relaxation, a support roll will be placed under the ankle. The intervention will be delivered by the same researcher for all participants to ensure consistency. Using the round head attachment, percussive therapy will be applied longitudinally along the hamstring muscle group (from proximal to distal) for a total of 120 seconds per leg. Specifically, 60 seconds will be applied to the semitendinosus and semimembranosus, and 60 seconds to the biceps femoris. The same procedure will then be repeated on the opposite leg.

Change in Hamstring Flexibility
Flexibility will be assessed using the sit-and-reach test before and after percussive therapy. The best of three attempts (in centimeters) will be recorded.
Time frame: Within 1 hour (pre- and post-intervention)
Change in Dynamic Balance
Balance will be evaluated using the Y-Balance Test in three directions (anterior, posteromedial, and posterolateral). Results will be normalized based on leg length and averaged (% of leg length).
Time frame: Within 1 hour (pre- and post-intervention)
Change in Vertical Jump Performance
Explosive strength will be measured using the My Jump Lab app, which calculates jump height and flight time. The best result of the three trials (in centimeters) will be used.
Time frame: Within 1 hour (pre- and post-intervention)
