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 .
P300, N400, aerobic fitness, and maximal aerobic exercise.
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 postexercise 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
