Tai Chi Mirrors the Benefits of Conventional Exercise in Adults with Central Obesity
As is well known, central obesity is a major manifestation of metabolic syndrome, including central obesity, dyslipidemia, hyperglycemia, low high-density lipoprotein cholesterol (HDL-C) level, and high blood pressure, which increases the risk for type 2 diabetes and cardiovascular disease.
In this study, 543 participants were randomly assigned in a 1:1:1 ratio to a control group with no exercise intervention (n= 181), conventional exercise consisting of aerobic exercise and strength training (EX group) (n= 181), and a tai chi group (TC group) (n= 181). The interventions lasted 12 weeks.
The outcomes included:
Decrease in waist circumference from baseline to week 12 in the control group was 0.8 cm (95% CI, 4.1 to 5.7 cm).
Both intervention groups showed reductions in WC relative to control (adjusted mean differences: TC group vs. control, 1.8 cm [CI, 2.3 to 1.4 cm]; P < 0.001; EX group vs. control: 1.3 cm [CI, 1.8 to 0.9 cm]; P < 0.001).
Both intervention groups also showed reductions in body weight (P < 0.05) and attenuation of the decrease in HDL-C level relative to the control group.
The favorable changes in WC and body weight were maintained in both the TC and EX groups, whereas the beneficial effect on HDL-C was only maintained in the TC group at week 38.
