Whole body vibration (WBV) training is an increasingly popular training method that is strongly promoted for weight loss, but scientific data on its effectiveness, particularly in obese subjects, are sparse. 14 obese women (BMI: 37.4 ± 1.3 kg/m2) randomized to 2 different groups (each n=7) participated in a 6-week endurance training program that was either combined or not combined with additional WBV training. Anthropometric measures, phase angle and body composition (assessed by bioelectrical impedance analysis; BIA), and resting energy expenditure (REE) were obtained before and after the training program. Body weight did not change during the training period (P=0.87), but waist circumference decreased in both groups (P=0.007; WBV: -3.4 ± 1.4 cm; no-WBV: -1.7 ± 0.7 cm) independent of WBV training (P=0.29 for group×time interaction). BIA revealed an enhancing effect of WBV training in comparison to no-WBV training on the phase angle (+0.20 ± 0.12° vs. -0.19 ± 0.12°; P=0.04) and calculated body cell mass (+0.8 ± 0.2 vs. -0.3 ± 0.4 kg; P=0.02), while calculated percentage fat mass decreased in both conditions (P=0.05) to similar extent (P=0.59; WBV: -0.8 ± 0.2%; no-WBV: -0.4 ± 0.5%). REE increased across the training (P=0.01; WBV: +77 ± 33 kcal/24 h; no-WBV: +68 ± 34 kcal/24 h), with this increase again not depending on WBV condition (P=0.85). Results of our pilot study in obese women provide preliminary evidence for a beneficial effect of WBV, when added to endurance training, on the bioelectrical phase angle, an increasingly recognized marker of individual's health status.
全身振动（WBV）训练是一种越来越受欢迎的训练方法，强烈推荐用于减肥，但关于其有效性的科学数据，特别是在肥胖受试者中的数据仍然很少。14 名肥胖女性（BMI：37.4±1.3kg/m2）随机分为 2 组（每组 n=7），分别参加了 6 周的耐力训练计划，其中一组或不结合额外的 WBV 训练。在训练计划前后获得了人体测量学指标、相位角和身体成分（通过生物电阻抗分析评估；BIA）以及静息能量消耗（REE）。在训练期间体重没有变化（P=0.87），但两组的腰围都减少了（P=0.007；WBV：-3.4±1.4cm；无 WBV：-1.7±0.7cm），与 WBV 训练无关（P=0.29 组×时间交互作用）。BIA 显示，与无 WBV 训练相比，WBV 训练对相位角（+0.20±0.12°对-0.19±0.12°；P=0.04）和计算的身体细胞质量（+0.8±0.2 对-0.3±0.4kg；P=0.02）有增强作用，而在两种情况下计算的脂肪质量百分比都降低（P=0.05），但程度相似（P=0.59；WBV：-0.8±0.2%；无 WBV：-0.4±0.5%）。REE 在整个训练过程中增加（P=0.01；WBV：+77±33kcal/24h；无 WBV：+68±34kcal/24h），这一增加也与 WBV 条件无关（P=0.85）。我们在肥胖女性中的初步研究结果提供了初步证据，表明在耐力训练中加入 WBV 对生物电相位角有有益影响，而相位角是个体健康状况的一个越来越被认可的标志物。
