[A trial of community-based well-rounded training for women inhabitants aged 65-74]

Well-rounded training, composed of resistance training, aerobic training and flexibility exercise, has been shown to be beneficial for increasing the physical strength of the elderly. The purpose of this study was to investigate the effects of a trial of community-based well-rounded training on women inhabitants to strengthen leg muscles.

The subjects were the women aged 65 to 74 years living in E city, Gifu prefecture in Japan, who gave informed consent for participation in a community-based well-rounded training class in 2003 or 2004 (n = 24), while others taking part in a recreation class for the aged served as the controls (n = 15). The training class was performed once a week for 12 weeks, while the recreation class was conducted every two weeks for 12 weeks. Self-reported questionnaire surveys of health status and examinations of physical characteristics and physical fitness were conducted before the beginning of each class and after the end of the 12-week class.

In the training class, the replies to the following items of questionnaires were significantly improved: "Are you confident in your present physical strength? (P < 0.01)", "How long can you walk at your ease? (P < 0.05)" and "How many times do you go out usually? (P<0.05)." On the other hand, there were no significant changes in the recreation class. Regarding physical fitness, both subjects and controls had significant improvements in a 10 meter-walking test, a body reaction time test and a 30-sec chair-stand test. In addition, training class attendees showed an increase in forward bending ability, an index of flexibility (P < 0.01), and the cross-sectional area of femoral region muscles measured by computer tomography (P < 0.05).

The present trial in a community suggested that well-rounded training has some beneficial effects to increase or maintain the physical strength of the leg muscles and the flexibility of bending among inhabitants aged 65-74. Community-based well-rounded training programs for the aged will assume greater importance with the rapid increase in aging populations.
