低，中，高体力活动的老年人与年轻的控制组相比，在中性和不兼容的条件下的侧翼任务的皮层电和行为反应。与年轻人相比，高度和中度活跃的老年人表现出增加的事件相关电位成分P3振幅的不兼容的条件下，在额叶电极网站。在中性条件下，只有低活动的老年人表现出降低幅度在中央顶叶网站，年轻人相比。P3潜伏期显示低活动老年人的潜伏期最长，其次是中等活动，高活动，年轻人，分别。反应时间（RT）数据显示，与所有三个老年组相比，年轻人表现出更快的RT。结果表明，体力活动可能会改善老年人的执行控制功能，通过影响P3振幅的分布，这与记忆和注意力的过程，并通过减少P3潜伏期，这与认知处理的速度。
Electrocortical and behavioral responses of low, moderate, and high physically active older adults where compared with a younger control group on neutral and incompatible conditions of a flankers task. Compared to younger adults, high and moderate active older adults exhibited increased event-related potentials component P3 amplitude for the incompatible condition at the frontal electrode site. For the neutral condition, only low active older adults exhibited decreased amplitude at the central-parietal site, compared to younger adults. P3 latency revealed the longest latencies for low active older adults, followed by moderate active, high active, and younger adults, respectively. Reaction time (RT) data revealed that younger adults exhibited faster RT compared to all three older groups. Results suggest that physical activity may improve executive control function in older adults by affecting the distribution of P3 amplitude, which has been related to memory and attentional processes, and by decreasing P3 latency, which relates to the speed of cognitive processing.
