| Research Abstract |
1.This study examined effects of aerobic exercises on physical fitness and functional capacity for 103 older adults living in the community. The effects were compared between low-fit and high-fit groups on the results of the physical fitness tests before aerobic exercise. After six months, the low-fit group improved physical fitness and the TMIG (Tokyo Metropolitan Institute of Gerontology) index of competence which is developed to assess functional capacity of older people, but high-fit group. These results suggest that six months exercise for low-fit older adults is effective to improve not only their physical fitness, but also functional capacity.
2.A randomized controlled study conducted to examine the effects of exercise intervention on the physical fitness, functional capacity and health status of low-fit elderly living in the community. Thirty-eight low-fit persons were randomized and allocated to either exercise group or control group. The results showed that exercise intervention for the low-fit elderly has beneficial effects on aerobic capacity and subjective health, but is less effective in improving functional capacity. The beneficial effects are not sustained following cessation of intervention.
3.The purpose of this study was to examine the effects of resistance training on gait changes in older people living in the community, and associations between gained strength and improved walking speed, step length and cadence. The results indicated that a 14-week resistance training helped to improve in knee extension and knee flexion strength and maximum walking speed, step length and cadence. Especially improvements in maximum walking speed associated with increased knee flexion strength.
