• Conditions: Physical Inactivity; Postural Balance; Athletic Performance

• Registration Number: NCT07152275
• Lead Sponsor: Hacettepe University

Brief Summary

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.

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.

• Study Design: PARALLEL

Primary Outcome Measures

Name	Time	Method
Change in Hamstring Flexibility	Within 1 hour (pre- and post-intervention)	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.
Change in Dynamic Balance	Within 1 hour (pre- and post-intervention)	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).
Change in Vertical Jump Performance	Within 1 hour (pre- and post-intervention)	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.
