The goal of this study was to compare the acute effects of whole-body vibration (WBV) delivered by 3 devices with different mechanical behavior on jump force (JF) and jump rate of force development (JRFD). Twelve healthy persons (4 women and 8 men; age 30.5 ± 8.8 years; height 178.6 ± 7.3 cm; body mass 74.8 ± 9.7 kg) were exposed to WBV for 15 and 40 seconds using 2 professional devices (power plate [PP; vertical vibration] and Galileo 2000 [GA; oscillatory motion around the horizontal axis in addition to vertical vibration]) and a home-use device [Power Maxx, PM; horizontal vibration]). The JF and JRFD were evaluated before, immediately after, and 5 minutes after WBV. The JF measured immediately after 40 seconds of vibration by the GA device was reduced (3%, p = 0.05), and JRFD measured after 5 minutes of rest after 40 seconds of vibration by the PM device was reduced (12%, p < 0.05) compared with the baseline value. The acute effects of WBV (15 or 40 seconds) on JF and JRFD were not significantly different among the 3 devices. In conclusion, our hypothesis that WBV devices with different mechanical behaviors would result in different acute effects on muscle performance was not confirmed.
本研究的目的是比较 3 种具有不同机械特性的全身振动（WBV）设备对跳跃力（JF）和力发展速率（JRFD）的急性影响。12 名健康人（4 名女性和 8 名男性；年龄 30.5±8.8 岁；身高 178.6±7.3cm；体重 74.8±9.7kg）分别使用 2 种专业设备（功率板[PP；垂直振动]和 Galileo 2000[GA；除了垂直振动外，还围绕水平轴进行振荡运动]）和 1 种家用设备[Power Maxx，PM；水平振动]接受 WBV 刺激，持续 15 秒和 40 秒。在接受 WBV 之前、之后即刻和之后 5 分钟评估 JF 和 JRFD。GA 设备振动 40 秒后立即测量的 JF 降低（3%，p=0.05），PM 设备振动 40 秒后休息 5 分钟后测量的 JRFD 降低（12%，p<0.05）与基线值相比。3 种设备的 WBV（15 或 40 秒）对 JF 和 JRFD 的急性影响无显著差异。总之，我们假设具有不同机械特性的 WBV 设备会对肌肉性能产生不同的急性影响，但这一假设并未得到证实。
