Exercise Intensity of the Traditional Chinese Mind–Body Exercise, Baduanjin, during Performance amongst Beginners

Abstract Objective The traditional Chinese mind–body exercise, Baduanjin, has remained popular for a thousand years for strengthening the body, promoting health and preventing chronic diseases. However, research on its exercise intensity is lacking. This study measured the exercise intensity of beginners practicing Baduanjin to provide scientific evidence for health promotion and exercise prescriptions. Methods A total of 20 healthy adults (13 males, 7 females) aged between 35 and 45 years, who had not practiced Baduanjin previously, were recruited. The average METs, HR, HRR, VO2, VO2/kg, VO2/HR, RR, RQ and VE were measured using the Italian Cosmed/K5 wireless portable exercise cardiopulmonary testing system. Results The average METs during Baduanjin was 2.92 ± 0.65. The mean maximum and mean average HR were 109.35 ± 17.83 and 95.34 ± 13.99, respectively. During Baduanjin, the exercise intensity indicators showed significant increases (P < 0.001) in VO2, VO2/kg, METs, HR, VO2/HR, RR and VE compared with the resting state. Additionally, the mean RQ increased (P < 0.05). Conclusion Baduanjin is a low-intensity exercise for beginners. HR reached its maximum in the later stages of Baduanjin, significantly decreased immediately after exercise and returned to near-resting levels within three minutes post-exercise. Baduanjin, as a low-intensity exercise, could be recommended for population members suitable to practice.
