Meditative movement (MM) practices are increasingly being studied, including examination of the potential for these modalities to contribute to weight management.
A search was conducted for randomized controlled trials testing one or both of two forms of MM, Tai Chi and Qigong, reporting effects on changes in body composition. Data from these studies were extracted and tabled, and a meta-analysis of studies with inactive control conditions was conducted. Risk of bias was assessed, and seven RCTs had a low risk of bias. Sources of bias include publication bias and selection of English only.
Publications meeting inclusion criteria yielded 24 studies (N = 1621 participants). Significant improvements in body composition, primarily body mass index, were noted for 41.7% of studies. A synthesis table describes the distribution of design factors, including type of comparison condition (inactive vs. active) and baseline body composition status (whether or not overweight/obese). A meta-analysis was conducted on 12 studies with inactive controls (using a random effects model) finding a small-to-medium treatment effect (SMD = - 0.388, CI = [- 0.732, - 0.044], t = 2.48, p < 0.03) for TC or QG interventions with a high level of heterogeneity.
Tai Chi and Qigong show demonstrable effects on body composition, when compared to inactive control conditions. Systematic evaluation and valid conclusions regarding the impact of Tai Chi and Qigong on body composition outcomes will require more targeted study designs and control of comparison conditions.
冥想运动（MM）练习正越来越多地被研究，包括考察这些方式对体重管理的潜在作用。
检索了测试两种形式的MM（太极拳和气功）中的一种或两种并报告对身体成分变化影响的随机对照试验。提取这些研究的数据并制成表格，并对有非活动对照条件的研究进行荟萃分析。评估了偏倚风险，7项随机对照试验的偏倚风险较低。偏倚来源包括发表偏倚和仅选择英文文献。
符合纳入标准的出版物产生了24项研究（N = 1621名参与者）。41.7%的研究中身体成分有显著改善，主要是体重指数。一个综合表描述了设计因素的分布，包括比较条件的类型（非活动与活动）和基线身体成分状态（是否超重/肥胖）。对12项有非活动对照的研究进行了荟萃分析（使用随机效应模型），发现太极拳或气功干预有小到中等的治疗效果（标准化均数差= -0.388，可信区间= [-0.732, -0.044]，t = 2.48，p < 0.03），异质性水平较高。
与非活动对照条件相比，太极拳和气功对身体成分有明显影响。关于太极拳和气功对身体成分结果影响的系统评价和有效结论将需要更有针对性的研究设计和比较条件的控制。
