A three-month programme of simplified (13-form) taichi qigong (two x sixty minute sessions a week) was found to be superior to both an exercise group (walking plus breathing techniques) and a control group (usual activities) in improving symptoms of chronic obstructive pulmonary disease (COPD).
The taichi qigong participants showed significant improvements in their lung function, activity tolerance (a six-minute walking test) and COPD exacerbation rate. There were no changes reported in the exercise group, while lung function declined in the control group. Chan AW, Lee A, Suen LK, et al.
