Tai Chi Reduces Waist Size Among Older Adults

JAMA. 2021;326(4):299. doi:10.1001/jama.2021.10833

Tai chi was as effective as conventional exercise for reducing central obesity in middle-aged and older adults, according to a trial published in the Annals of Internal Medicine. The authors recommended incorporating the gentle mind-body exercise into physical activity guidelines for older people.

The trial’s 543 participants aged 50 years or older were located at a single research site in Hong Kong. They were randomly assigned to a control group with no exercise, to aerobic exercise and strength training, or to a tai chi group for 12 weeks. An instructor led the conventional exercise and tai chi groups, which met 3 times a week for 1 hour.
