摘要

Background: This study investigated the effects of tai chi on body composition, self-efficacy, and life satisfaction of older adults in a Korean community. Methods: A randomized, control group pretest-posttest, experimental design was used to investigate 42 adults aged 65 years or older. Subjects were divided into an experimental group that underwent tai chi training for 6 weeks (n = 20) and a control group that did not (n = 22). Body composition, self-efficacy, and life satisfaction were measured before and after a 6-week tai chi intervention program (5 days/week). Results: Compared to the control group, the experimental group showed significant reductions in body mass index (BMI) (p ＜ 0.004) and body fat (p ＜ 0.001) and significant increases in skeletal muscle mass (p ＜ 0.001) and life satisfaction (p ＜ 0.001). Self-efficacy increased in the experimental group but was not significantly different from that of the control group (p ＜ 0.265). Conclusion: Tai chi is an effective exercise intervention that may improve body composition and life satisfaction for older adults.
