Tai Chi Improves Bone Density

The graceful movements of this ancient art may build bone better than resistance training.

Originally a fighting art, the Chinese system of tai chi has evolved into a popular form consisting of graceful movements that strengthen muscles by tensing and relaxing them, and massage joints during slow transitions.

Who would have thought that such slow, rhythmic moves could also build bone? Apparently researchers at Texas Tech University did. They compared tai chi and resistance training on bone metabolism in a group of 28 sedentary adults (average age 80), who did one or other of the exercise protocols for 40 minutes three times a week. After 24 weeks, there was a reduction of urinary calcium in the tai chi group compared to beginning levels, but not in the resistance-training group. “We think the reduction in urinary calcium would help mitigate bone loss in this population,” noted lead researcher Chwan-Li (Leslie) Shen, Ph.D., concluding that tai chi “is beneficial for increasing bone formation in the elderly.”
