수중운동이 고령여성의 Amyloid-beta(1-42), 우울 및 인지에 미치는 영향

Abstract

The purpose of this study was to investigate the effects of aquatic exercise on amyloid-beta, depression, cognitive function in elderly women. The subjects were thirty elderly females volunteers, aged 65 to 80 years, composed of the aquatic exercise group (n=17) and control group (n=13). The 60 minute aquatic exercise program was performed 2 times per week for 16 weeks, and the intensity was progressively increased every four weeks(1-4 weeks:40-50%HRR, 5-8 weeks:50-60%HRR, 9-12 weeks: 60-65%HRR, 13-16 weeks: 65-70%HRR). The test data were analyzed by two-way repeated measures ANOVA, paired t-test, independent t-test, Pearson correlation, and the alpha level of p.05 was set for all tests of significance. The results of the study in the aquatic exercise group were as follows; The amyloid-beta, cognitive function had significantly increased, but depression score had significantly decreased. Amyloid-beta was negatively correlated with depressive scores and was positively correlated with cognitive scores. In conclusion, in elderly women exposed to degenerative brain disease due to aging, stress, poor eating habits, lack of exercise, environmental pollution, aquatic exercise showed a positive effect on amyloid-beta increase, depression decrease and cognitive function increase. Therefore, it will be helpful to improve the quality of life of elderly women in the elderly.
