本研究探讨急性有氧运动对老年人认知脑功能的影响。24名男性（12名老年人和12名年轻人）在基线时段（无运动）和在不同天以平衡顺序进行轻、中度自行车运动后执行了一项修改后的侧卫任务，同时收集了任务表现和事件相关脑电位P3部分的测量结果。结果表明，对于两个年龄组，中度运动后的反应时间相对于其他时段较短，轻度和中度运动后的P3潜伏期均较基线时段短。相比之下，在年轻人中，P3振幅仅在适度运动后增加。这些发现表明，轻度和中度运动可以改善成年人的认知功能，尽管观察到的急性有氧运动对认知功能的影响机制可能与年龄有关。
The present study investigated the effects of acute aerobic exercise on cognitive brain functions of older adults. Twenty-four males (12 older and 12 younger adults) performed a modified flanker task during a baseline session (no exercise) and after light and moderate cycling exercise in counterbalanced order on different days while measures of task performance and the P3 component of an event-related brain potential were collected. The results indicated that, for both age groups, reaction time following moderate exercise was shorter relative to the other sessions, and P3 latencies following both light and moderate exercise were shorter compared with the baseline session. In contrast, P3 amplitude increased only following moderate exercise in younger adults. These findings suggest that light and moderate exercises improve cognitive function across the adult lifespan, although the mechanisms underlying the effects of observed acute aerobic exercise on cognitive function may be age dependent.
