심폐체력이 전두엽의 집행기능에 미치는 영향: ERP를 통한 연구

The purpose of the present study is to examine the relationship between aerobic capacity and cerebral cortical responses in young male adult whose prefrontal lobe is in the middle of development. It was also examined to see if this relationship is stronger in frontally-mediated executive function task, relative to attentional task. Participants were 60 college age young healthy male (M=19.89 yrs) who underwent fitness testing to estimate aerobic capacity. Cognitive function was assessed by neuroelectrical response, an event-related potential (ERP) during executive task and non-executive task. Electroencephalogram (EEG) was recorded at Fz, Cz, and Pz during cognitive challenges. As the result, aerobic capacity was positively associated with P300 amplitude at Fz and Cz during executive function task. P300 latencies at Fz, Cz, Pz during executive challenge and at Pz during non-executive task was shorter in high-fit participants, relative to those who are low-fit. The current finding revealed that aerobic capacity yields neuro-electrical benefit with increasing allocation of attentional resources and making cognitive-processing speed short. The benefit of aerobic capacity was greater during frontally-mediated executive challenge.
