目的：探讨短期全身振动训练是否对老年男性和女性的骨量和结构有有益影响。设计：随机对照试验。方法：共有49名非住院老年人(男性20名，女性29名)自愿参加研究。符合纳入标准的参与者被随机分配到其中一个研究组(全身振动或对照组)。24名经过训练的老年人每周在振动台上蹲3次，共11周。采用双能X线骨密度仪和外周定量计算机断层扫描对骨相关变量进行评估。采用双向重复测量、单因素方差分析(按时间分组)来确定干预对骨相关变量的影响，并确定干预期间组内的变化。使用协方差分析来检验训练前和训练后评估中的骨相关变量组之间的差异以及组间变化的百分比。结果：11周全身振动训练后，骨矿物质含量和双能X线骨密度仪测量的骨密度参数均未见改变。在胫骨，全身振动组的总骨量、骨小梁和皮质体积骨密度均显著降低(均P
Objectives: We aimed to clarify whether a short-term whole body vibration training has a beneficial effect on bone mass and structure in elderly men and women.Design: Randomised controlled trial.Methods: A total of 49 non-institutionalised elderly (20 men and 29 women) volunteered to participate in the study. Participants who met the inclusion criteria were randomly assigned to one of the study groups (whole body vibration or control). A total of 24 elderly trained squat positioned on a vibration platform 3 times per week for 11 weeks. Bone-related variables were assessed by dual-energy X-ray absorptiometry and peripheral quantitative computed tomography. Two-way repeated measures one-way analysis of variance (group by time) was used to determine the effects of the intervention on the bone-related variables and also to determinate the changes within group throughout the intervention period. Analysis of covariance was used to test the differences between groups for bone-related variables in pre- and post-training assessments and in the percentage of change between groups. All analysis were carried out including age, height, subtotal lean mass and daily calcium intake as covariates.Results: 11 weeks of whole body vibration training led to no changes in none of the bone mineral content and bone mineral density parameters measured by dual-energy X-ray absorptiometry through the skeleton. At the tibia, total, trabecular and cortical volumetric bone mineral density decreased significantly in the whole body vibration group (all P
