Research on the acute effects of exercise on cognitive performance by older adults is limited by a focus on nonhealthy populations. Furthermore, the duration of cognitive improvements after exercise has not been examined. Thus, this study was designed to test the immediate and delayed effects of acute exercise on cognitive performance of healthy older adults. Cognitive performance was assessed using the Stroop task. Participants were randomly assigned to an exercise (20 min of walking) or control (sitting quietly) condition. The Stroop task was administered at baseline and at 12 time points after treatment. Acute exercise resulted in better Stroop test performance immediately postexercise; however, the effects were limited to the color test. No effects of exercise on performance were observed for the Stroop interference or inhibition tests. Findings suggest that acute exercise performed by healthy older adults has short-term benefits for speed of processing but does not affect other types of cognitive functioning.
对老年人运动对认知表现的急性影响的研究因聚焦于非健康人群而受到限制。此外，运动后认知改善的持续时间尚未得到研究。因此，本研究旨在测试急性运动对健康老年人认知表现的即时和延迟影响。使用斯特鲁普任务评估认知表现。参与者被随机分配到运动组（20分钟步行）或对照组（安静坐着）。在基线和治疗后的12个时间点进行斯特鲁普任务。急性运动在运动后立即导致更好的斯特鲁普测试表现；然而，这些影响仅限于颜色测试。对于斯特鲁普干扰或抑制测试，未观察到运动对表现的影响。研究结果表明，健康老年人进行的急性运动对处理速度有短期益处，但不影响其他类型的认知功能。
