Percussive Therapy in U19 Males: Flexibility, Balance, Jump

"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."
