METHODS: One hundred Tai Chi practitioners participated in this investigation. Men and women were separated into three groups: young (25-44 y/o), middle-aged (45-64 y/o) and elderly (65-80 y/o). Heart rate (HR) responses during Tai Chi practice were measured by using electrocardiographic telemetry. An exercise test with breath-by-breath measurements of cardiorespiratory function was also performed for each subject during the incremental exercise of leg cycling. Measurements obtained during the Tai Chi practice and exercise testing were compared to determine the exercise intensity of Tai Chi. While performing Tai Chi, the mean HR of men was 141, 132 and 120 in the young, middle-aged and elderly groups, respectively. The mean HR of women was 136, 126 and 115 in the young, middle-aged and elderly groups, respectively. RESULTS: The results demonstrate that classical Yang TCC is an exercise with moderate intensity, and its exercise intensity is similar across different ages in each gender. In conclusion, TCC is an aerobic exercise and suitable for participants of different ages and gender to improve their functional capacity.

Relative exercise intensity of Tai Chi Chuan is similar in different ages and gender
