Numerous factors influence weight management, including the choice of physical exercise. No study has previously examined the therapeutic effect of a multidisciplinary weight management program incorporating Tai Chi (TC) exercises among sedentary obese women. DESIGN: Randomized intervention trial with blinded medical provider. SETTING: In day hospital consultations. PARTICIPANTS: Twenty-one obese women. INTERVENTION: All subjects participated in a 10-week weight management program that was part of usual care and included a hypocaloric balanced diet, a weekly physician/psychologist/dietician group session, and an exercise program. For the exercise component, subjects were randomized to either a 2-hour weekly session of TC or a conventional structured exercise program. MAIN OUTCOME MEASURES: Changes in weight, body composition, heart rate, blood pressure, mobility scores, mood, Three Factor Eating Questionnaire scores, and General Self-Efficacy. RESULTS: The TC arm improved in resting systolic blood pressure, chair rise test, mood, and reduced percent of fat at week 10 and at 6 months follow-up. General self-efficacy was enhanced in both groups and maintained at 30 weeks. CONCLUSION: The observed benefits over a 30-week period of a multidisciplinary weight management program incorporating TC exercises on physical functioning mood and dietary restraint need further understanding of how sedentary obese women adhere to physical activity like TC or other alternative exercises

Effects of exercise programs to prevent decline in health-related quality of life in highly deconditioned institutionalized elderly persons: a randomized controlled trial.

METHODS: A randomized controlled trial of 2 exercise programs vs usual care was conducted in 160 institutionalized persons 65 years or older who were able to understand basic motor commands and to move from one position to another. Interventions were performed over 6 months and were either an adapted tai chi program (4 times 30 min/wk) or a cognition-action program (2 times 30-45 min/wk) that focused primarily on an adapted guidance of patient-centered communication skills. The control group received usual care. The study was conducted at 4 settings. The main outcomes were changes in health-related quality of life based on ADL and Neuropsychiatric Inventory scores after 12 months. RESULTS: The control group experienced a decline in ADL over the 12-month period compared with the adapted tai chi and cognition-action groups, but the differences were not significant (P = .24 and P = .15, respectively). Also, the components of ADL, eg, ability to walk, continence, and nutrition, were maintained better in the intervention groups than in the control group. The total Neuropsychiatric Inventory score also worsened significantly in the control group, while it was unchanged or improved in the intervention groups. The differences between the cognition-action group and the control group were significant (P > .001). Neuropsychiatric diagnosis subgroups (such as dementia and psychosis) did not show a specific response from any intervention. CONCLUSION: Adapted exercise programs can slow down the decline in health-related quality of life among heterogeneous, institutionalized elderly persons.
