노인 여성의 유산소성 운동이 체력, 청각기능 및 정신기능에 미치는 영향

Abstract

The purpose of this study was to investigate the effects of regular exercises on body composition, physical fitness, hearing function, and mental function in elderly women. The subjects of the study was 30 elderly women aged 65 years or older, and the exercise groups were the elderly who has been performed swimming (n=10) and aerobics (n=10) for at least 2 years. The control group (n=10) was the elderly who did not exercise regularly for last 3 month. The results are as follows.<BR> In the case of body composition, the body weight of the swimming group was significantly higher among the 3 groups and the regular exercise groups were significantly higher in lumbar flexibility, TUG and grip strength than the control group. In particular, the lumbar flexibility of the aerobic exercise group was approximately 8.4 times and 1.9 times higher than that of the control group and the swimming group, respectively. The hemodynamic variables were no significant difference between the 3 groups. The hearing threshold in all subjects in this study showed the highest threshold in the 4 ㎑ frequency band rather than the 05 ㎑, 1 kHz and 2 ㎑. Significant differences were observed between the 3 groups in the left hearing, and the hearing threshold (40% to 25dB) of the aerobic group was higher than those of the other two groups. Depression was significantly lower in the two exercise groups than in the control group.<BR> In conclusion, it was recognized that the elderly women’s regular exercise improved their physical fitness level, but did not significantly affect their hearing functions. Particularly, long-term exercise in a high-pitched music sound might be a negative effects on the hearing function in the elderly people. Nevertheless, regular exercise is evaluated to reduce depression in the elderly.
