Acute Effects of Percussion Massage Therapy in Young Competitive Cyclists

"Participants assigned to the intervention group will receive a single session of percussion massage therapy (PMT) using the Compex® Fixx™ 2.0 handheld device. The treatment will be applied bilaterally to three major muscle groups: gluteus maximus, quadriceps femoris, and gastrocnemius.~The device will operate at a high intensity setting (Level 4) with a frequency of 41.7 Hz.~A wedge-shaped applicator head will be used to ensure consistent pressure across the treatment area.~Each muscle group will be treated for 3 minutes, following a standardized linear stroke pattern from proximal to distal and back.~The total duration of the intervention will be approximately 18 minutes.~The intervention will be performed once, immediately before the post-test evaluations, and aims to assess acute effects on neuromuscular performance."
