通过比较P300和N400在最大循环试验前后的电生理效应，研究有氧健身和最大有氧运动的电生理效应。从20名学生中获得事件相关电位（ERPs），根据他们的有氧健身水平分为两组（骑自行车者和久坐者）。在体温和心率恢复到运动前值后立即进行运动后erp。在休息时，骑车者和久坐者之间的ERP参数没有显著差异。这一发现反驳了ERP改变可能直接由有氧适应度水平决定的假设。所有受试者的运动后erp均显示P300振幅显著增加，P300潜伏期显著减少。类似的。N400效应在最大运动后显著增加。两组的ERP变化幅度相同。本研究认为最大有氧运动具有普遍的唤醒作用，与有氧健身水平无关。
Electrophysiological effects of aerobic fitness and maximal aerobic exercise were investigated by comparing P300 and N400 before and after a maximal cycling test. Event-related potentials (ERPs) were obtained from 20 students divided into two matched groups defined by their aerobic fitness level (cyclists vs. sedentary subjects). The session of post exercise ERPs was performed immediately after body temperature and heart rate returned to preexercise values. At rest, no significant differences were observed in ERP parameters between cyclists and sedentary subjects. This finding argued against the hypothesis that ERP modifications may be directly assumed by aerobic fitness level. The postexercise session of ERPs showed a significant P300 amplitude increase and a significant P300 latency decrease in all subjects. Similarly. N400 effect increased significantly after the maximal exercise in all subjects. ERP changes were of the same magnitude in the two groups. The present study argues for a general arousing effect of maximal aerobic exercise, independently of the aerobic fitness level.
