Body Composition Outcomes of Tai Chi and Qigong Practice: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

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. 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 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.
