A review of scientific literature suggests that there is strong evidence of beneficial health effects of tai chi and qi gong, including for bone health, cardiopulmonary fitness, balance, and quality of life.
Researchers from the Institute of Integral Qigong and Tai Chi (Santa Barbara, California), Arizona State University, and the University of North Carolina analyzed 77 articles reporting the results of 66 randomized controlled trials of tai chi and qi gong. The studies involved a total of 6,410 participants.
Of the many outcomes identified by the reviewers, current research suggests that the strongest and most consistent evidence of health benefits for tai chi or qi gong is for bone health, cardiopulmonary fitness, balance and factors associated with preventing falls, quality of life, and self-efficacy (the confidence in and perceived ability to perform a behavior).
