先前的研究已经确定了急性运动对认知表现的影响，这激发了对神经生物学机制的研究，这可能是观察到的好处的基础。瞳孔反应被认为反映了这种潜在的神经生物学机制的激活。目前的研究招募了健康的年轻人，以调查在抑制控制任务中，单次中等到高强度有氧运动对随后的表现和瞳孔反应的影响。结果表明，在抑制控制任务中，急性运动回合与较短的反应时间和增加的强直性瞳孔扩张有关。虽然瞳孔反应没有介导急性运动对抑制控制的影响，但相对于坐着休息，运动后较高的心肺适应性与更大的相瞳孔扩张有关。目前的研究支持瞳孔反应作为LC-NE系统激活的标志，对急性运动敏感的合理性。瞳孔反应是否可以解释急性运动对大脑和认知的短暂益处尚不清楚。
Previous research has established an impact of acute exercise on cognitive performance, which has inspired investigations into neurobiological mechanisms that may underlie the observed benefits. Pupillary responses have been posited to reflect activation of such underlying neurobiological mechanisms. The current study recruited healthy young adults to investigate the effects of a single bout of moderate-to-vigorous intensity aerobic exercise on subsequent performance and pupillary responses during an inhibitory control task. Results showed that an acute bout of exercise was related to shorter reaction times and increased tonic pupil dilation during an inhibitory control task. Although pupillary responses did not mediate the acute exercise effect on inhibitory control, higher cardiorespiratory fitness was associated with greater phasic pupil dilation following exercise relative to seated rest. The current study supported the plausibility of the pupillary response as a marker of LC-NE system activation that is sensitive to acute exercise. Whether pupillary responses could account for transient benefits of acute exercise on brain and cognition remains unclear.
