Sociological and physiological empirical research on dementia prevention effect of calisthenics

对岛根县出云市74名参加痴呆预防班的老年人进行了干预研究。研究对象为24名男性和50名女性，平均年龄为74.61±5.92岁。在运动功能方面，单腿站立睁眼(最大值)、单腿睁眼站立(平均值)、最小起跑时间(TUG)、平均TUG、5m正常步行速度、5m最大步行速度与干预前相比均有显著改善。在营养状况方面，血清总蛋白值和白蛋白值无显著差异。在认知功能方面，与健忘有关的项目数量、同伴认同率和短期记忆健忘率显著下降。此外，握力(运动功能)、血清总蛋白和白蛋白(营养状况)与认知功能呈显著相关。TUG(运动功能)呈显著负相关。多元回归分析显示，认知功能、握力和拖拽之间存在显著关系。老年人参加健康课增加了日常运动量，从而改善了运动功能。随着老年人运动量的增加，有可能通过营养指导来控制过度的能量消耗。实施这些护理预防计划与改善认知功能有关。

An intervention study was carried out on 74 elderly persons attending dementia prevention classes in Izumo City, Shimane Prefecture. The subjects in the study were 24 men and 50 women with a mean age of 74.61±5.92 years. With regard to motor function,standing on one leg with eyes open (maximum value), standing on one leg with eyes open (mean value), minimum Timed Up and Go (TUG), mean TUG, 5 m normal walking speed, and 5 m maximum walking speed showed significant improvement after the intervention compared to the pre-intervention level. With regard to nutritional status, there were no significant differences in serum total protein value or albumin value. With regard to cognitive function, there were significant decreases in the number of items relating to forgetfulness, the rate of identification by peers, and the rate of short-term memory forgetfulness. Furthermore, grip strength (motor function) and serum total protein value and albumin value (nutritional status) showed significant correlation to cogn itive function. TUG (motor function) showed a significant negative correlation. M ultiple regression analysis showed a significant relationship between cognitive function, grip strength, and TUG. The participation of elderly persons in health classes increa ses the daily amount of exercise, so that motor function improves. With the increase in the amount of exercise in elderly persons, it was possible to keep excessive energy consumption in check by nutritional guidance. Carrying out these care prevention programs is linked to improved cognitive function.
