Whole-body vibration training (WBVT) confers a continuous vibration stimuli to the body. Although some reports have discussed the effects of whole-body vibration (WBV) on bone mineral density and muscle strength, study of WBV effects on lean mass have not been determined. The purpose of the present meta-analysis was to evaluate published, randomized controlled trials (RCTs) that investigated the effects of WBVT on lean mass.
We identified only RCTs by searching databases, including Web of Science, PubMed, Scopus, Embase, and the Cochrane Library from inception to March 2017. Data extraction, quality assessment, and meta-analysis were performed.
Ten RCTs with 5 RCTs concentrating on older people, 3 on young adults, and 2 on children and adolescents were included. We additionally explored the effect of WBVT on postmenopausal women (6 trials from the 10 trials). Significant improvements in lean mass with WBVT were merely found in young adults (P = .02) but not in other populations compared to control group.
The effect of WBVT found in the present meta-analysis may be used in counteracting the loss of muscle mass in younger adults. Moreover, optimal WBVT protocols for greater muscle hypertrophy are expected to be investigated.
全身振动训练（WBVT）会给身体带来持续的振动刺激。尽管一些报告讨论了全身振动（WBV）对骨密度和肌肉力量的影响，但关于WBV对瘦体重影响的研究尚未确定。本荟萃分析的目的是评估已发表的、研究WBVT对瘦体重影响的随机对照试验（RCT）。
我们通过检索数据库来识别RCT，这些数据库包括Web of Science、PubMed、Scopus、Embase以及从创刊到2017年3月的Cochrane图书馆。进行了数据提取、质量评估和荟萃分析。
纳入了10项RCT，其中5项集中于老年人，3项针对年轻人，2项针对儿童和青少年。我们还探讨了WBVT对绝经后女性的影响（10项试验中的6项）。与对照组相比，仅在年轻人中发现WBVT使瘦体重有显著改善（P = 0.02），而在其他人群中未发现。
本荟萃分析中发现的WBVT效果可用于对抗年轻成年人肌肉量的流失。此外，有望对促进更大肌肉肥大的最佳WBVT方案进行研究。
