The relationship of physical activity to trial-by-trial adjustments of response conflict was assessed using behavioral task performance, the N2 event-related brain potential component, and phase-locking values (PLVs) in a lower gamma band during a perceptual conflict task. Nineteen physically active and 19 inactive young adults (mean age = 21.3 years) performed a Navon task, using a global letter made up of local letters of either the same kind (congruent trials) or a different kind (incongruent trials). Findings revealed that active individuals exhibited smaller N2 amplitudes and greater PLVs on incongruent trials that were preceded by incongruent trials compared with those preceded by congruent trials. Such phenomena were not observed for inactive individuals. These results suggest that greater physical activity is associated with larger trial-bytrial adjustments of response conflict, which we attribute to upregulation of top-down cognitive control and reductions in response conflict.
