Objectives

To assess the effects of whole-body vibration training (WBVT) on body composition, metabolic and cardiovascular risk variables, and lower limb strength in participants who are overweight/obese.

Data Sources

A systematic review with meta-analysis was conducted in 3 databases (PubMed-MEDLINE, Web of Science, and Cochrane Library) from inception through to January 26, 2020.

Study Selection

: Studies analyzing the effect of WBVT on body composition variables, metabolic profile, blood pressure, heart rate, and lower limb strength in the population who are overweight/obese, with interventions of a minimum length of 2 weeks were included.

Data Extraction

After applying the inclusion and exclusion criteria, 23 studies involving 884 participants who were obese/overweight (experimental group: 543; weight=79.9 kg; body mass index (BMI) =31.3 kg/m², obesity class I according to World Health Organization) were used in the quantitative analysis. The sex of the participants involved in the studies were as follows: (1) 17 studies included only female participants; (2) 1 study included only boys, and (3) 5 studies included both sexes. Meta-analysis, subgroup analysis, and meta-regression methods were used to calculate the mean difference and standardized mean difference (SMD; ± 95% confidence intervals [CIs]) as well as to analyze the effects of pre-post intervention WBVT and differences from control groups.

Data Synthesis

WBVT led to a significant decrease in fat mass (−1.07 kg, not clinically significant). In addition, WBVT reduced systolic blood pressure (−7.01 mmHg, clinically significant), diastolic blood pressure (−1.83 mmHg), and heart rate (−2.23 bpm), as well as increased the lower extremity strength (SMD=0.63; range, 0.40-0.86). On the other hand, WBVT did not modify the weight, BMI, muscle mass, cholesterol, triglycerides, or glucose.

Conclusions

WBVT could be an effective training modality to reduce blood pressure (clinically relevant) and resting heart rate. In addition, WBVT led to improved lower limb strength. However, these findings were not consistent with significant improvements on other variables associated with metabolic syndrome (body composition, cholesterol, triglycerides, glucose).

全身振动训练对超重和肥胖人群的身体成分、心脏代谢风险和力量的影响：荟萃分析的系统评价

目标

评估全身振动训练 (WBVT) 对超重/肥胖参与者的身体成分、代谢和心血管风险变量以及下肢力量的影响。

数据源

从开始到 2020 年 1 月 26 日，在 3 个数据库（PubMed-MEDLINE、Web of Science 和 Cochrane 图书馆）中进行了荟萃分析的系统评价。

研究选择

：研究分析了 WBVT 对超重/肥胖人群的身体成分变量、代谢特征、血压、心率和下肢力量的影响，并进行了至少 2 周的干预。

数据提取

应用纳入和排除标准后，23 项研究涉及 884 名肥胖/超重参与者（实验组：543 人；体重=79.9 kg；体重指数（BMI）=31.3 kg/m ²，世界卫生组织肥胖 I 级） ) 用于定量分析。参与研究的参与者的性别如下： (1) 17 项研究仅包括女性参与者；(2) 1 项研究仅包括男孩，(3) 5 项研究包括两性。采用Meta分析、亚组分析和Meta回归方法计算平均差和标准化平均差（SMD；±95%置信区间[CIs]），并分析干预前后WBVT的影响和差异来自对照组。

数据综合

WBVT 导致脂肪量显着减少（-1.07 kg，无临床意义）。此外，WBVT 降低收缩压（-7.01 mmHg，具有临床意义）、舒张压（-1.83 mmHg）和心率（-2.23 bpm），并增加下肢力量（SMD=0.63；范围， 0.40-0.86）。另一方面，WBVT 没有改变体重、BMI、肌肉质量、胆固醇、甘油三酯或葡萄糖。

结论

WBVT 可能是降低血压（临床相关）和静息心率的有效训练方式。此外，WBVT 可改善下肢力量。然而，这些发现与代谢综合征相关的其他变量（身体成分、胆固醇、甘油三酯、葡萄糖）的显着改善不一致。
