Conclusions drawn from this systematic review suggest that physical activity and cardiorespiratory fitness are associated with P3b modulation during cognitive control and attention tasks .
Acute and chronic physical activity interventions modulate the P3b component , suggesting short- and long-term functional adaptations occurring in the brain to support cognitive processes .
These summary findings suggest physical activity and cardiorespiratory fitness are beneficial to brain function and that P3b may serve as a biomarker of covert attentional processes to better underst and the relationship of physical activity and cognition
Given accumulating evidence indicating that acute and chronic physical activity and cardiorespiratory fitness are related to modulation of the P3b-ERP component , this systematic review provides an overview of the field across the last 30 + years and discusses future directions as the field continues to develop .
Differential influences of exercise intensity on information processing in the central nervous system
The influence of exercise intensity on information processing in the central nervous system was investigated using P300 and no-go P300 event-related potentials . Twelve subjects ( 22–33 years ) performed a go/no-go reaction time task in a control condition , and again after high- , medium- , and low-intensity pedaling exercises . Compared to the control condition , P300 amplitude decreased after high-intensity pedaling exercise and increased after medium-intensity pedaling exercise . There was no change after low-intensity pedaling exercise . These results suggested that the amount of attentional re sources devoted to a given task decreased after high-intensity exercise and increased after medium-intensity exercise . The findings also suggest that changes in P300 amplitude are an inverted U-shaped behavior of differences in exercise intensity . In addition , no-go P300 amplitude showed the same changes as P300 amplitude at different exercise intensities . This indicates that differences in exercise intensity influenced not only the intensity of processing the requirement for a go response , but also processing of the need for a no-go response . It is concluded that differences in exercise intensity influenced information processing in the CNS
