简要总结
This randomized controlled trial aims to investigate the acute effects of percussion massage therapy (PMT) on balance, explosive strength, and functional performance in adolescent competitive cyclists aged 12-15. A total of 32 participants will be randomly assigned to either a PMT group, which will receive a single session of vibration-based therapy using a handheld percussion device (Compex Fixx 2.0), or a control group with passive rest. Performance parameters will be assessed using the Y Balance Test, vertical jump, hop tests, 10-second sprint cycling, and isometric muscle strength via dynamometry. The study seeks to determine whether PMT offers short-term neuromuscular benefits that may enhance cycling performance in youth athletes.
详细描述
Cycling is a sport that requires repetitive and rhythmic activation of the lower extremity muscles, where balance, endurance, and muscular power are critical. In adolescent athletes aged 12-15, musculoskeletal structures are still developing, and interventions aimed at enhancing performance must be carefully investigated in terms of both efficacy and safety.
Percussion massage therapy (PMT) is a novel method that combines elements of traditional massage and vibration therapy, applying rapid mechanical pulses to soft tissues using handheld devices. PMT has gained popularity in recent years due to its potential to enhance circulation, reduce muscle stiffness, and improve neuromuscular function. Studies suggest that PMT can produce acute effects such as improved proprioception, reduced muscle tone, and enhanced explosive performance.
This randomized controlled trial aims to evaluate the acute effects of PMT on dynamic balance, explosive strength, and functional performance in young competitive cyclists. Thirty-two participants, aged 12 to 15, who have been licensed cyclists for at least 2 years and train regularly, will be randomly assigned to either an intervention group receiving PMT or a control group undergoing passive rest.
The intervention group will receive a single session of PMT using the Compex® Fixx™ 2.0 device, applied bilaterally to the gluteus maximus, quadriceps femoris, and gastrocnemius muscles at 41.7 Hz for 3 minutes per muscle group. The control group will remain seated for an equivalent rest period.
Performance outcomes will be assessed using the Y Balance Test, Vertical Jump Test, single-leg hop test (triple hop), 10-second cycling sprint test, and handheld dynamometry to measure isometric muscle strength. In addition, subjective muscle relaxation will be evaluated pre- and post-intervention using the Numeric Rating Scale (NRS).

结局指标
主要结局
Y Balance Test Composite Score
时间窗: Pre-intervention and immediately post-intervention
The Y Balance Test will be used to assess dynamic balance by measuring reach distances in three directions (anterior, posteromedial, and posterolateral) while standing on one leg. Each direction will be tested three times, and the average reach distance will be normalized to leg length. A composite score will be calculated and expressed as a percentage to evaluate overall dynamic balance capacity. Higher scores indicate better balance performance.
