Short-Term Tensiomyography Responses of the Vastus Medialis to Percussive Massage Therapy with Different Frequency–Duration Combinations

: Clinically realistic PMT protocols at 35-45 Hz in non-fatigued muscle induce small but statistically detectable, duration-sensitive changes in TMG-derived contractile behavior over approximately 10 min. Within the constraints of the fixed, non-randomized design and the small effect sizes observed, these findings support viewing massage gun use as a recovery-oriented adjunct that subtly modulates contractile dynamics, rather than as a strong, standalone performance-enhancing stimulus.
