我们调查了体育锻炼和老年人认知能力之间的关系。我们假设，在推理、工作记忆和反应时间方面，剧烈运动者的表现要比久坐者好上级。我们给62名剧烈运动的老年男性和女性以及62名久坐的男性和女性一系列认知任务。以年龄和教育程度为协变量的多变量和单变量方差分析表明，锻炼者在推理、工作记忆和反应时间方面的表现明显更好。当词汇量作为第三个协变量时，组间差异仍然存在，而词汇量是锻炼者表现最好的上级。随后的分析表明，自我评估的健康状况，医疗条件和药物都不会导致运动组之间的差异。结果表明，体育锻炼的可能贡献的认知中老年人的个体差异，应进一步调查。
We investigated relationships between physical exercise and the cognitive abilities of older adults. We hypothesized that the performance of vigorous exercisers would be superior to that of sedentary individuals on measures of reasoning, working memory, and reaction time. We gave a series of cognitive tasks to 62 older men and women who exercised vigorously and 62 sedentary men and women. Multivariate and univariate analyses of variance, with age and education as covariates, indicated that the performance of the exercisers was significantly better on measures of reasoning, working memory, and reaction time. Between-group differences persisted when vocabulary, on which the performance of exercisers was superior, was used as a third covariate. Subsequent analyses showed that neither self-rated health, medical conditions, nor medications contributed to the differences between exercise groups. Results suggest that the possible contribution of physical exercise to individual differences in cognition among older adults should be further investigated.
