Forty-seven TCQG practitioners with a mean age of 60.7 ± 9.9 years participated in this study. The cardiorespiratory responses and energy expenditure were measured by a K4 telemetry system. TCQG has 54 motions and can be divided into 3 sets. The result indicated that the exercise intensity of each motion is about 3 metabolic equivalents (MET) and the energy expenditure of each set is about 60 Kcal. The estimated intensity of TCQG in elderly individuals approximated 50% of the maximum oxygen uptake (V? O2max) for men, and 60% of the maximum oxygen uptake (V? O2max) for women. The findings demonstrate that TCQG is a low intensity exercise and can be prescribed as an alternative exercise program for cardiopulmonary rehabilitation. ? 2002 World Scientific Publishing Company & Institute for Advanced Research in Asian Science and Medicine.[SDGs]SDG3adult; aged; article; body movement; cardiopulmonary hemodynamics; controlled study; energy expenditure; exercise; female; human; male; motion; oxygen consumption; Tai Chi; telemetry; aging; blood pressure; breathing mechanics; drug effect; energy metabolism; health promotion; heart rate; hemodynamics; middle aged; physiology; risk factor; sexual development; Adult; Aged; Aging; Blood Pressure; Energy Metabolism; Female; Health Promotion; Heart Rate; Hemodynamic Processes; Humans; Male; Middle Aged; Oxygen Consumption; Respiratory Mechanics; Risk Factors; Sex Characteristics; Tai Ji; Telemetryjournal article10.1142/S0192415X02000636125682732-s2.0-0038352255
