简要总结
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.

结局指标
主要结局
Muscle tension of the rectus femoris measured by myotonometry (Hz)
时间窗: Assessed at baseline, immediately after the fatigue protocol, and immediately after the 5-minute vibrational percussion massage intervention.
Muscle tension represents the resting tone of the rectus femoris muscle, quantified by oscillation frequency. Higher values indicate greater resting muscle tension.
Muscle stiffness of the rectus femoris measured by myotonometry (N/m)
时间窗: Assessed at baseline, immediately after the fatigue protocol, and immediately after the 5-minute vibrational percussion massage intervention.
Dynamic stiffness represents the resistance of the rectus femoris muscle to external deformation, with higher values indicating greater muscle stiffness and lower tissue compliance.
Muscle elasticity of the rectus femoris measured by myotonometry (logarithmic decrement)
时间窗: Assessed at baseline, immediately after the fatigue protocol, and immediately after the 5-minute vibrational percussion massage intervention.
Muscle elasticity represents the ability of the rectus femoris muscle to restore its original shape after deformation. Lower values indicate better elasticity and lower energy dissipation.
Mechanical stress relaxation time of the rectus femoris measured by myotonometry (ms)
时间窗: Assessed at baseline, immediately after the fatigue protocol, and immediately after the 5-minute vibrational percussion massage intervention.
Mechanical stress relaxation time represents the time required for the rectus femoris muscle to recover from deformation after an external mechanical impulse. Longer values indicate more compliant (softer) tissue, whereas shorter values indicate increased muscle stiffness.
Creep of the rectus femoris measured by myotonometry (ratio)
时间窗: Assessed at baseline, immediately after the fatigue protocol, and immediately after the 5-minute vibrational percussion massage intervention.
Creep represents the viscoelastic deformation of the rectus femoris muscle under a constant mechanical load. Higher values indicate greater tissue elongation capacity and viscoelastic deformation, whereas lower values suggest reduced compliance.
次要结局
- Maximal isometric knee extensor strength measured by handheld dynamometry (N)(Assessed at baseline, immediately after the fatigue protocol, and immediately after the 5-minute vibrational percussion massage intervention.)
- Triple-hop distance test (m)(Assessed at baseline, immediately after the fatigue protocol, and immediately after the 5-minute vibrational percussion massage intervention.)
