In order to better understand which training approaches are more effective for preventing bone loss in post-menopausal women with low bone mass, we examined the effect of a nine-month resistive exercise program with either an additional whole body vibration exercise (VIB) or balance training (BAL).
68 post-menopausal women with osteopenia were recruited for the study and were randomised to either the VIB or BAL group. Two training sessions per week were performed. 57 subjects completed the study (VIB n=26; BAL n=31). Peripheral quantitative computed tomography (pQCT) measurements of the tibia, fibula, radius and ulna were performed at baseline and at the end of the intervention period at the epiphysis (4% site) and diaphysis (66% site). Analysis was done on an intent-to-treat approach.
Significant increases in bone density and strength were seen at a number of measurement sites after the intervention period. No significant differences were seen in the response of the two groups at the lower-leg.
This study provided evidence that a twice weekly resistive exercise program with either additional balance or vibration training could increase bone density at the distal tibia after a nine-month intervention period in post-menopausal women with low bone mass.
为了更好地了解哪种训练方法对预防骨量低的绝经后女性骨质流失更有效，我们研究了一项为期九个月的抗阻运动计划的效果，该计划分别附加了全身振动训练（VIB）或平衡训练（BAL）。
招募68名患有骨质减少的绝经后女性参与本研究，并将她们随机分为VIB组或BAL组。每周进行两次训练课程。57名受试者完成了研究（VIB组n = 26；BAL组n = 31）。在基线以及干预期结束时，在骨骺（4%部位）和骨干（66%部位）对胫骨、腓骨、桡骨和尺骨进行外周定量计算机断层扫描（pQCT）测量。分析采用意向性分析方法。
干预期结束后，在多个测量部位观察到骨密度和骨强度显著增加。两组在小腿部位的反应未见显著差异。
本研究提供了证据，表明对于骨量低的绝经后女性，在为期九个月的干预期后，每周两次的抗阻运动计划附加平衡训练或振动训练均可增加胫骨远端的骨密度。
