Abstract
The mechanisms of the cute effect of eaobic exercise on cognition and neuroelectrical dependents are not completely clear. The present study aims to investigate the impact of physical activity on evoked potentials during the flanker attention task through the analysis of event-related potentials (ERP).
Method: fifteen adolescent boys with an average age of 14.07±1.12 participated in this study. The participants came to the laboratory on two different days. Once without running and once after 20 minutes of aerobic running, they performed the flanker test while recording ERP. Using EEGLAB, ERP components including P2, N2, and P3 were extracted in Fz and Pz channels. Wilcoxon non-parametric test and SPSS version 20 software were used to answer the research hypotheses.
Results: The results of the research showed that a session of aerobic exercise significantly increased the amplitude of the P3 and N2 in the Fz channel and decreased the delay time of their appearance (P<0.05). These changes were not confirmed in the Pz channel. The amplitude of the P2 did not change significantly due to aerobic running (P<0.05), but this component appeared significantly earlier in the Pz channel (P<0.05).
Conclusion: The study's results demonstrated that the endogenous ERPcomponents during the flanker attention task were significantly enhanced following aerobic Exercise. The quicker appearance of the P2 is likely a result of improved perception in the parietal region. Therefore, engaging in aerobic physical activity is suggested as a method to enhance cognitive performance before engaging in activities that require high levels of mental processing.
