Older adults engaging in regular physical activity can help create a buffer toward cognitive decline. The main aim of this study was to assess the effects of physical activity and cognitive functioning on a sample of young-old and old-old physically active adults and young-old and old-old sedentary adults. Cognitive functioning was examined using the digit span test, Wisconsin card sorting task. The National Task Group-Early Detection Screen for Dementia measure was used explore the relationship between scores and physical activity and sedentary adults. Findings from the study showed partial support for physical activity has a positive relationship with cognitive functioning. The results found Young-old adults did better on the DST than all other groups regardless of being sedentary or physically active. Young-old physically active adults, however, did better on the DST latency measure than sedentary adults while old-old physically active adults did worse on the DST latency measure compared with old-old sedentary adults. The results also found that Physically active adults had a better score on the NTG-EDSD measure compared to the sedentary adults. Findings showed no significant differences for the WCST. Future research exploring the relationship between physical activity and cognitive functioning should do so by having more control over the extraneous variables.
经常进行体育活动的老年人有助于为认知能力下降建立缓冲。本研究的主要目的是评估体育活动和认知功能对一组年轻老年人和年老老年人中体育活动活跃的成年人以及年轻老年人和年老老年人中久坐不动的成年人的影响。使用数字广度测试、威斯康星卡片分类任务来检查认知功能。使用国家任务组-痴呆早期检测筛查量表来探究得分与体育活动及久坐不动成年人之间的关系。该研究的结果部分支持了体育活动与认知功能之间存在正相关关系这一观点。结果发现，无论久坐还是体育活动活跃，年轻老年人在数字广度测试中的表现都优于所有其他组。然而，年轻老年人中体育活动活跃的成年人在数字广度测试潜伏期测量中的表现优于久坐不动的成年人，而年老老年人中体育活动活跃的成年人在数字广度测试潜伏期测量中的表现比年老老年人中久坐不动的成年人更差。结果还发现，与久坐不动的成年人相比，体育活动活跃的成年人在国家任务组-痴呆早期检测筛查量表上得分更高。结果显示在威斯康星卡片分类任务中没有显著差异。未来探索体育活动与认知功能之间关系的研究应该通过对无关变量进行更多控制来开展。
