Acute effects of the duration of percussive massage on flexibility and muscle force
摘要
Percussive massage (PM) is performed using massage guns. Recently, PM has gained popularity, and it is commonly performed to improve flexibility and performance. However, the acute effects of different durations of PM are unclear.
AimsThis randomized, crossover trial examined the acute effects of different PM durations on the range of motion (ROM), peak passive torque (PPT), passive stiffness, and isometric muscle force.
MethodsSixteen healthy young men participated in this study. PM of the right plantar flexors for 60, 180, and 300 s, and 300 s resting as a control condition, were performed on four separate days in random order. We measured the ROM, PPT, and passive stiffness during passive ankle dorsiflexion. We also measured the maximum voluntary isometric ankle plantar flexion force immediately before and after the intervention.
ResultsThe ROM and PPT were significantly increased, and passive stiffness was significantly decreased after all PM interventions (all p < 0.05), while isometric muscle force was unchanged. There were strong and moderate positive correlations between the interventions and the relative change in ROM (ρ = 0.670, p < 0.01) and PPT (ρ = 0.566, p < 0.01). There was a weak negative correlation between the interventions and the relative change in passive stiffness (ρ = −0.371, p < 0.05).
ConclusionsOur results suggest that PM for more than 60 s improves flexibility, including ROM, PPT, and passive stiffness, without any change in isometric muscle force. Moreover, a longer duration of PM may further improve flexibility.
