The purpose of this study was to determine the effectiveness of combined aerobic and resistance training circuit on daily physical activity, motor function, and health-related QOL among community-dwelling women aged over 65. Of 102 subjects recruited from the local community, 60 met the inclusion criteria. The subjects were randomly divided into two groups: intervention and control. The intervention group was asked to participate in 60 minutes of combined aerobic and resistance training circuit three times a week for 3 months, while the control group was asked to participate in a study circle once a month for 3 months. Daily physical activity was measured by an activity monitor, and questionnaire, physical functioning, and health related QOL were measured before and after intervention. Daily physical activity as measured by the activity monitor increased significantly in the intervention group but not in the control group, although daily physical activity as measured by questionnaire did not significantly differ between groups. Distance walked over 6 minutes significantly increased in the intervention group than in the control group. No significant difference was found in health related QOL between groups. We conclude that combined aerobic and resistance training circuit is effective for increasing daily activity in community-dwelling older women and for enhancing physical function.
