Previous studies showed that local vibration stimulation therapy was effective in relieving fatigue, and the effects of different modes of vibration stimulation therapy were further investigated.
This study aimed to examine the effects of different vibration stimulation modes on relieving acute exercise fatigue based on the multiphysiological indicators such as heart rate variability (HRV), skin conductance level (SCL), and ratings of perceived exertion (RPE) subjective scale.
Sixty participants selected from the dragon boat team of the Shanghai University of Traditional Chinese Medicine were divided into acupoint stimulation group (20 participants), muscle stimulation group (20 participants), and control group (20 participants) by complete randomization.
(1) RPE: both stimulation groups showed a significant increase compared to the control group. (2) Heart rate values: the difference between muscle stimulation group and control group was statistically significant; (3) SCL: the two stimulation groups had significantly higher and statistically significant differences in SCL (max) and SCL (mean) values compared to the control group; the muscle stimulation group had statistically significant differences in SCL (min) compared to the control group, and the acupoint stimulation group had statistically significant differences in SCL (v) compared to the control group; (4) HRV (hf): The difference between the acupoint stimulation group and the muscle stimulation group was statistically significant.
(1) Both stimulation groups are part of vibration therapy, which can relieve sympathetic tension and regulate the vegetative nervous system's relaxation effect. (2) The meridian-vessel theory may be related to the acupoint stimulation group. The low-level visceral regulation centers in the spinal nerve segment region, where the acupoints are located, trigger changes in autonomic tone and enhance parasympathetic nerve activity to relieve acute motor fatigue. (3) The muscle stimulation group may be due to the 30-Hz vibration frequency's ability to raise muscle epidermal temperature, which increases blood flow and reflexively inhibits sympathetic excitation.
先前的研究表明，局部振动刺激疗法在缓解疲劳方面是有效的，并且进一步研究了不同模式的振动刺激疗法的效果。
本研究旨在通过心率变异性（HRV）、皮肤电导率水平（SCL）和主观感知用力程度（RPE）等多生理指标，考察不同振动刺激模式对缓解急性运动疲劳的影响。
通过完全随机分组的方式，将上海中医药大学龙舟队的 60 名队员分为穴位刺激组（20 人）、肌肉刺激组（20 人）和对照组（20 人）。
（1）RPE：与对照组相比，两组刺激组均有显著增加。（2）心率值：肌肉刺激组与对照组之间存在显著差异；（3）SCL：与对照组相比，两组刺激组的 SCL（max）和 SCL（mean）值均有显著升高且具有统计学意义；与对照组相比，肌肉刺激组的 SCL（min）值有显著差异，穴位刺激组的 SCL（v）值有显著差异；（4）HRV（hf）：穴位刺激组与肌肉刺激组之间存在显著差异。
（1）两种刺激组都属于振动疗法的一部分，可以缓解交感神经紧张，调节植物神经系统的放松效果。（2）经络理论可能与穴位刺激组有关。位于穴位的脊神经节区域的低级内脏调节中枢触发自主神经张力的变化，增强副交感神经活动，从而缓解急性运动性疲劳。（3）肌肉刺激组可能是由于 30Hz 的振动频率能够提高肌肉表皮温度，增加血流量，并反射性抑制交感神经兴奋。
