Abstract
The aim of the present study was to investigate the acute effect of aerobic physical activity on the neuroelectrical components evoked following an attention task in adolescent boys.
In this research, 15 teenage boys participated in the available form with an average age of 14.07 ± 1.12. The participants visited the laboratory on two separate days and performed the flanker task while recording the EEG/ERP. They were randomly assigned to perform aerobic activity for their first session or their second session. To record the EEG/ERP, a 32-active channel EEG was used. The Psytask software, developed by Mitsar company in Russia, was used to present the flanker task. The EEG data was analyzed using EEGLAB software, and the ERP components, including P2, N2, and P3 were extracted from Fz, Cz, and Pz channels. SPSS version 20 was used for statistical analysis. Wilcoxon's non-parametric test was utilized to answer the research hypotheses.
The findings of the study indicated that following an aerobic exercise session, there was a significant increase in the amplitude of endogenous P3 and N2 components in Fz and Cz channels, along with a decrease in their delay. However, these changes were not observed in the Pz channel. The amplitude of the P2 component did not change significantly in any of the three channels, but its delay was not significantly altered in the Fz and Cz channels, whereas it appeared significantly earlier in the Pz channel.
The available data show that the neuroelectric components underlying various cognitive processes are affected by acute physical activity obvious contradictions have been observed in the literature. Although the explanation of changes in the neuroelectrical profile of cognitive performance due to acute physical activity requires more extensive studies, this research clearly showed that the endogenous ERP components in the flanker attention task were significantly facilitated after aerobic physical activity. This facilitation was not confirmed concerning the P2 component as an exogenous component related to the characteristics of the stimulus. Therefore, aerobic physical activity is recommended as a strategy for cognitive facilitation before activities with high processing demands.
