| Abstract |
The purpose of this study was to investigate the changes of health related fitness and Dehydroepiandrosterone sulfate (DHEAs) after 12 weeks of combined exercise. Subjects were consisted of fourteen elderly women. The training program included stretching for 10 minutes, aerobic exercise (weight bearing exercise and balance exercise at an intensity above 40∼59% of HRR during 1~6 weeks, and 60~84% of HRR during 7~12 weeks) for 30 minutes and 20 minutes of resistance exercise (muscle strengthening+posture correction). The program was conducted 3 times a week for 12 weeks. We found that LBM (lean body mass) was significantly (p<.05) increased and gait ability were significantly improved after combined exercise. Also DHEAs concentration was significantly increased after combined exercise but testosterone was not changed. In conclusion, the combined exercise showed a positive influence on body composition and health related fitness. In particular DHEAs concentration were significantly improved after combined exercise. Therefore, it might be thought that combined exercise would be a positive role in the of aging. |
