Effectiveness pf a community-based Tai Chi program and implications for public health initiatives

METHODS: Phase 1: 51 subjects inexperienced in Tai Chi (novice group) were compared with those of an experienced group (n=49) who had practiced Tai Chi for at least 6 months. A Cheng 119 style program was taught by a Tai Chi master for 1.5 hours, 3 times weekly, for 12 weeks. Lung function and physical activity were evaluated before and after the completion of the program. Resting heart rate, blood pressure, oxygen saturation, handgrip strength, flexibility, and balance were measured at the program commencement, 6 weeks, and 12 weeks. RESULTS: After the program, the novice group had increased handgrip strength, flexibility, and peak expiratory flow rate. The experienced group had greater flexibility and lower resting heart rate, but higher diastolic blood pressure than the novice group prior to training.
