The aim of this research was to examine whether high-frequency whole-body vibration activates the tonic vibration reflex (TVR).
The experimental study was conducted with seven volunteers (mean age: 30.8±3.3 years; range, 26 to 35 years) between December 2021 and January 2022. To elicit soleus TVR, high-frequency (100-150 Hz) vibration was applied to the Achilles tendon. High-frequency (100-150 Hz) whole-body vibration and low-frequency (30-40 Hz) whole-body vibration were applied in quiet standing. Whole-body vibration-induced reflexes were recorded from the soleus muscle using surface electromyography. The cumulative average method was used to determine the reflex latencies.
Soleus TVR latency was 35.6±5.9 msec, the latency of the reflex activated by high-frequency whole-body vibration was 34.8±6.2 msec, and the latency of the reflex activated by low-frequency whole-body vibration was 42.8±3.4 msec (F=40.07, p=0.0001, ƞ =0.87). The low-frequency whole-body vibration-induced reflex latency was significantly longer than high-frequency whole-body vibration-induced reflex latency and TVR latency (p=0.002 and p=0.001, respectively). High-frequency whole-body vibration-induced reflex latency and TVR latency were found to be similar (p=0.526).
This study showed that high-frequency whole-body vibration activates TVR.
本研究旨在探讨高频全身振动是否能激活紧张性振动反射（TVR）。
2021年12月至2022年1月期间，对7名志愿者（平均年龄：30.8±3.3岁；范围26至35岁）进行了实验研究。为引出比目鱼肌TVR，对跟腱施加高频（100 - 150Hz）振动。在安静站立时施加高频（100 - 150Hz）全身振动和低频（30 - 40Hz）全身振动。使用表面肌电图从比目鱼肌记录全身振动诱发的反射。采用累积平均法确定反射潜伏期。
比目鱼肌TVR潜伏期为35.6±5.9毫秒，高频全身振动激活的反射潜伏期为34.8±6.2毫秒，低频全身振动激活的反射潜伏期为42.8±3.4毫秒（F = 40.07，p = 0.0001，ƞ = 0.87）。低频全身振动诱发的反射潜伏期显著长于高频全身振动诱发的反射潜伏期和TVR潜伏期（分别为p = 0.002和p = 0.001）。高频全身振动诱发的反射潜伏期和TVR潜伏期相似（p = 0.526）。
本研究表明高频全身振动可激活TVR。
