The literature on aerobic exercise and neurocognition reports acute post-exercise enhancement of neural activity linked to motor preparation in the premotor area and inhibitory control in the frontoparietal areas. However, the acute effect of vigorous-intensity aerobic exercise (VIAE) on the prefrontal, the insular, and the occipito-parietal activities linked to proactive control, early perceptual, arid attentional processing is indeterminate. Thus, the present study investigated the acute effect of VIAE on the neurobehavioral correlates of these proactive and reactive neurocognitive functions. Young, healthy subjects participated in two separate experimental sessions: 30 min of VIAE and 30 min of internet browsing. Before and immediately after the two sessions, we recorded high-resolution electroencephalograms while performing a visuomotor discriminative response task. For testing the effect of VIAE on cognitive processing, we analyzed the behavioral performance and event-related potentials (ERPs). The analysis of behavioral data did not reveal any VIAE effect on task performance. The analysis of ERPs showed no significant VIAE effect on the proactive functions in the premotor and the prefrontal areas, but significant effects on the reactive functions related to selective attention in parietal areas (indexed by the N1 amplitude) and perceptual awareness in the anterior insula (indexed by the pN1 latency). We concluded that a single bout of VIAE does not affect the proactive functions in the premotor and the prefrontal areas, but modulates the early reactive neural mechanisms underlying perceptual awareness of stimuli in the insular cortex and selective attention in the parieto-occipital areas.

Abstract

The literature on aerobic exercise and neurocognition reports acute post-exercise enhancement of neural activity linked to motor preparation in the premotor area and inhibitory control in the frontoparietal areas. However, the acute effect of vigorous-intensity aerobic exercise (VIAE) on the prefrontal, the insular, and the occipito-parietal activities linked to proactive control, early perceptual, arid attentional processing is indeterminate. Thus, the present study investigated the acute effect of VIAE on the neurobehavioral correlates of these proactive and reactive neurocognitive functions. Young, healthy subjects participated in two separate experimental sessions: 30 min of VIAE and 30 min of internet browsing. Before and immediately after the two sessions, we recorded high-resolution electroencephalograms while performing a visuomotor discriminative response task. For testing the effect of VIAE on cognitive processing, we analyzed the behavioral performance and event-related potentials (ERPs). The analysis of behavioral data did not reveal any VIAE effect on task performance. The analysis of ERPs showed no significant VIAE effect on the proactive functions in the premotor and the prefrontal areas, but significant effects on the reactive functions related to selective attention in parietal areas (indexed by the N1 amplitude) and perceptual awareness in the anterior insula (indexed by the pN1 latency). We concluded that a single bout of VIAE does not affect the proactive functions in the premotor and the prefrontal areas, but modulates the early reactive neural mechanisms underlying perceptual awareness of stimuli in the insular cortex and selective attention in the parieto-occipital areas.
