The purpose of this study was to progressively overload vibration platform frequency to describe sea-saw whole body vibration influence on neuromuscular performance of community-dwelling older adults. Seventy-three community-dwelling older adults (aged 72 +/- 8 years) were randomly assigned to 4 groups (zero, one, 2, and 3 whole body vibration sessions per week). Quantifiers of neuromuscular performance such as the 5-Chair Stands test, the Timed Up and Go (TUG) test, and the Tinetti test were recorded. Furthermore, Health-related quality of life was qualified with the SF-36 Health Survey. A 6-week whole body vibration intervention significantly improved the quantifiers of neuromuscular performance in a community-dwelling older adult sample. Whole body vibration was shown to significantly reduce time taken to complete the 5-Chair Stands test (p < 0.05) and the TUG test (p < 0.05). Tinetti test scores significantly improved (p < 0.05). as did all components of health-related quality of life (p < 0.05). Overall, progressively overloaded frequency elicited more beneficial improvement for the 3 whole body vibration sessions per week group. It was concluded that progressively overloaded frequency was effective in improving quantifiable measures of neuromuscular performance in the sample and that practitioners may confidently prescribe 3 whole body vibration sessions per week with more precise knowledge of the effects of whole body vibration on neuromuscular performance and health-related quality-of-life effects.
本研究的目的是逐步增加振动平台频率，以描述跷跷板式全身振动对社区居住老年人神经肌肉性能的影响。73名社区居住的老年人（年龄72±8岁）被随机分为4组（每周零次、一次、两次和三次全身振动训练）。记录神经肌肉性能的量化指标，如5次坐椅起立测试、计时起立行走（TUG）测试和Tinetti测试。此外，使用SF-36健康调查对健康相关生活质量进行评估。为期6周的全身振动干预显著改善了社区居住老年样本中神经肌肉性能的量化指标。全身振动显示出显著减少完成5次坐椅起立测试的时间（p<0.05）和TUG测试的时间（p<0.05）。Tinetti测试得分显著提高（p<0.05），健康相关生活质量的所有组成部分也显著提高（p<0.05）。总体而言，每周进行3次全身振动训练的组，频率逐步增加带来了更有益的改善。研究得出结论，频率逐步增加有效地改善了样本中神经肌肉性能的可量化指标，从业者可以更准确地了解全身振动对神经肌肉性能和健康相关生活质量的影响，从而放心地开出每周3次全身振动训练的处方。
