Development of a novel exercise program for improving physical and cognitive functions in community-dwelling older Japanese adults

本研究的目的是调查新型运动项目对日本社区老年人认知功能的纵向影响。我们的研究分为两组：干预组（n = 40，平均年龄70.2 +/- 3.6岁）和对照组（n = 40，平均年龄70.1 +/- 3.6岁）。干预组（n = 40，平均年龄70.2 +/- 3.6岁）参与者自愿每周坚持锻炼一到两次，持续3年。我们使用5-cog测试评估认知功能。I组5-cog测试成绩在3年内显著升高，而C组无变化（I 69.7 ~ 84.1, P < 0.05; C 69.3 ~ 76.3，无统计学意义）。I组与C组在第三年的5齿测试得分差异有统计学意义（84.1分vs. 76.3分，P < 0.05）。这些结果表明，老年人在三年以上的时间里定期和自愿参加锻炼可以帮助他们保持或改善他们的认知功能。

The purpose of this study was to investigate the longitudinal effect of the novel exercise programs on the cognitive function of community-dwelling, older, Japanese adults. Our study had 2 groups: the intervention (I) group (n = 40; mean age 70.2 +/- 3.6 years) in which participants voluntarily continued the exercise programs once or twice per week for 3 years, and the Control (C) Group (n = 40; mean age 70.1 +/- 3.6 years). We assessed cognitive function using the 5-cog test. The 5-cog test scores in the I Group increased significantly over 3 years while no change was observed in the C Group (I 69.7 to 84.1, P < 0.05; C 69.3 to 76.3, not significant). The scores of the 5-cog test indicated a significant difference in the third year between the I and C groups (84.1 vs. 76.3 points, P < 0.05). These results suggest that regular and voluntary participation in the exercise by older adults over three years could help them maintain or improve their cognitive functions.
