About this study
Official title: The Effect of Percussive Therapy on Muscle Flexibility, Balance, and Jump Performance in Licensed U19 Football Players and Sedentary Healthy Males Under 19 Years of Age
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.
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Percussive TherapyDevice
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.
| Study group | Role | What they receive |
|---|---|---|
| Active Group (Licensed U19 Football Players) | Experimental | This group includes male adolescents aged 15-19 who have an active football license and engage in regular sports activity.
Intervention:
Name: Percussive Therapy Description: A 120-second percussive therapy protocol will be applied to each participant's hamstring muscles using a handheld massage gun (Hypervolt Go 2). The treatment includes 60 seconds on the semitendinosus and semimembranosus, and 60 seconds on the biceps femoris, performed while the participant is in a prone position.
Timing: Single session Device Used: Hypervolt Go 2 massage gun Receives: Device: Percussive Therapy |
| Sedentary Group (Non-Athlete Healthy Males) | Experimental | This group includes healthy male adolescents aged 15-19 who have not engaged in regular physical activity in the past 6 months and have a BMI below 25.
Intervention:
Name: Percussive Therapy Description: The same 120-second percussive therapy protocol will be applied as in the active group, under identical conditions and using the same device.
Timing: Single session Device Used: Hypervolt Go 2 massage gun Receives: Device: Percussive Therapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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).
Measured: 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.
Measured: Within 1 hour (pre- and post-intervention)
