The aim of this study was to analyze the effects of an 8-week whole-body vibration (WBV) on the quality of life, physical fitness, body composition, glycosylate hemoglobin (HbA1c), lipid profile, and foot health status in people with type II diabetes mellitus (T2DM). It was performed as a double-blinded randomized controlled trial of 90 people with T2DM. Primary care facilities were used. The 8-week WBV training consisted of maintaining a knee flexion at 45° during five to nine series of 30-60 s in a vibration frequency that oscillated between 12.5-18.5 and 30 s of recovery between series. The placebo group had to perform the same protocol but without vibration. Participants performed the protocol three times per week. The WBV training significantly reduced the fat mass (%) of people with T2DM. However, significant effects of WBV training were not found in the quality of life, physical fitness, foot health status, lipid profile, blood pressure, fasting blood glucose, or HbA1c. Nevertheless, within groups enhances were found in HbA1c, blood pressure, fasting blood glucose, foot health status, health-related quality of life, timed-up and go test, and chair-stand test in both WBV and placebo groups. WBV was shown to be beneficial for reducing the fat mass and lipid profile of people with T2DM. The improvements of the placebo group could be due to both the social benefits of enrolling in an intervention and the physical fitness benefits of isometric contractions. Further studies are needed to clarify the effects of WBV and to establish a dose-response relationship in people with T2DM.
本研究旨在分析为期 8 周的全身振动（WBV）对 2 型糖尿病（T2DM）患者生活质量、身体素质、身体成分、糖化血红蛋白（HbA1c）、血脂谱和足部健康状况的影响。这是一项针对 90 名 T2DM 患者的双盲随机对照试验。使用初级保健设施。为期 8 周的 WBV 训练包括在振动频率为 12.5-18.5 之间的情况下，保持膝关节弯曲 45°，进行五到九组 30-60 秒的振动，每组之间有 30 秒的恢复期。安慰剂组必须执行相同的方案，但没有振动。参与者每周进行三次方案。WBV 训练显著降低了 T2DM 患者的脂肪量（%）。然而，WBV 训练在生活质量、身体素质、足部健康状况、血脂谱、血压、空腹血糖或 HbA1c 方面没有显著效果。尽管如此，在 WBV 和安慰剂组中，均发现 HbA1c、血压、空腹血糖、足部健康状况、健康相关生活质量、计时起立行走测试和椅子站立测试的组内增强。WBV 被证明对降低 T2DM 患者的脂肪量和血脂谱有益。安慰剂组的改善可能归因于参与干预的社会效益和等长收缩的身体素质益处。需要进一步的研究来阐明 WBV 的影响，并确定 T2DM 患者的剂量反应关系。
