采用执行控制任务，通过比较20名大学生运动前后的神经电和行为表现，研究了急性心血管运动对认知功能的影响。受试者内部的设计被用来评估事件相关脑电位(ERP)的P3成分和行为表现，使用一项不同执行控制量的任务。基线会议包括参加埃里克森侧翼任务，然后进行分级的最大运动测试，以衡量心血管健康。锻炼过程包括在跑步机上进行30分钟的急性锻炼，然后在心率恢复到锻炼前10%的范围内后进行埃里克森侧翼任务。在中线记录部位，结果显示急性运动后P3波幅比基线更大。在中立者的基线Eriksen侧翼任务中，观察到与不相容的情况相比，P3潜伏期更短；这种影响在急性运动后没有发现。这些发现表明，心血管运动的急性发作通过增加神经电资源的分配以及通过改变认知加工和刺激分类速度来影响执行控制的基本神经电过程。(C)2003 Elsevier Science B.V.保留所有权利。
Acute cardiovascular exercise effects on cognitive function were examined using an executive control task by comparing neuroelectric and behavioral performance at baseline with post-exercise in 20 undergraduates. A within-subjects design was used to assess the P3 component of an event-related brain potential (ERP) and behavioral performance using a task that varied the amount of executive control required. The baseline session involved participation on the Eriksen flankers task followed by a graded maximal exercise test to measure cardiovascular fitness. The exercise session consisted of a 30-min acute bout of exercise on a treadmill followed by the Eriksen flankers task after heart rate returned to within 10% of pre-exercise levels. Across midline recordings sites, results indicated larger P3 amplitude following acute exercise compared to baseline. Shorter P3 latency was observed during the baseline Eriksen flankers task for the neutral compared to the incompatible condition; an effect not found following the acute bout of exercise. These findings suggest that acute bouts of cardiovascular exercise affect neuroelectric processes underlying executive control through the increased allocation of neuroelectric resources and through changes in cognitive processing and stimulus classification speed.
