Tai Chi as Physical Activity for Women With Morbid Obesity

This study investigated the use of Tai Chi as a feasible form of physical activity for women with morbid obesity utilizing an instructional digital video disc (DVD). Two groups of women with morbid obesity (body mass index of \>40) were placed into the Tai Chi intervention group or the control group. Initial function was assessed with a series of tests and then repeated after 8 weeks. During the 8 weeks, the Tai Chi intervention group met once a week for 45 minutes to participate in a group exercise class. The control group was asked to continue their regular activity. At the end of the 8 weeks, both groups were reassessed with the same tests from the start of the study. The investigators hypothesized that the Tai Chi group would show more improvement in their functional scores for strength, balance and quality of life than the control group.
