Abstract：Objective To study the differences and correlations in the localization of sustained attention related acti-vation brain regions and exercise cardiopulmonary function among pilots of different aircraft types and the general popula-tion.Methods A total of 14 active-duty pilots(8 fighter pilots and 6 transport pilots)and 9 general population were in-cluded in the study.During the psychomotor vigilance task(PVT),blood oxygen level dependent-functional magnetic res-onance imaging(BOLD-fMRI)technology was used to locate task related activated brain regions,and exercise cardiopul-monary function was evaluated by cardiopulmonary exercise testing(CPET),the correlation between brain function acti-vation and exercise cardiopulmonary function were analyzed.Results The results of BOLD-fMRI during PVT showed that the degree of oxygen activation in the right inferior frontal gyrus of pilots was significantly higher than that of the general population(P＜0.001),the activation level of the right inferior frontal gyrus in fighter pilots was significantly higher than that in transport pilots(P=0.009).The anaerobic threshold(AT),relative anaerobic threshold and maxi-mum oxygen pulse level of pilots were significantly higher than those of the general population(P＜0.05),the AT of transport pilots was significantly higher than that of fighter pilots(P=0.023).The degree of brain function activation in the right inferior frontal gyrus of pilots was significantly negatively correlated with AT values(r=-0.31,P=0.02).Conclusion The right inferior frontal gyrus may be a key brain area for sustained attention in pilots,and the activation of the right inferior frontal gyrus is nega-tively correlated with AT values.
