Vibrational Percussion Massage Improves Rectus Femoris Mechanical Properties and Sports Performance in Physically Active Adults

Brief Summary

The goal of this clinical trial is to learn if vibrational percussion massage (VPM) improves rectus femoris mechanical properties and sports performance after muscle fatigue in physically active adults. It will also examine the immediate effects of VPM on muscle function and recovery. The main questions it aims to answer are: * Does VPM improve the mechanical properties of the rectus femoris muscle after fatigue? * Does VPM improve knee extensor strength and triple-hop performance after fatigue? Researchers will compare measurements obtained before fatigue, after fatigue, and after a VPM intervention to evaluate the effects of VPM on muscle recovery and sports performance. Participants will: * Perform a fatigue protocol targeting the lower extremity muscles. * Receive a 5-minute VPM intervention after the fatigue protocol. * Complete assessments of rectus femoris mechanical properties using a myotonemeter. * Perform maximal isometric knee extensor strength and triple-hop distance tests at three time points: before fatigue, after fatigue, and after VPM intervention.
