Abstract：Objective To investigate the relationship between fatigue status of young soldiers and salivary cortisol as well as attention function, and provide references for finding objective indicators of fatigue evaluation.Methods Thirty-four young soldiers were investigated and analyzed by fatigue assessment instrument (FAI), saliva collection and attention network test (ANT).Results The main effects of the clue type (no clue, central clue, double clue, spatial clue), target state (consistent, inconsistent, neutral) and the interaction of clue types and target states were significant.The reaction time of control network was significantly longer than that of alert network and orienting network (P＜0.001), but there were no significant correlation among executive control network, alert network and orienting network (P＞0.05).The dimension 4 fatigue of FAI scale was negatively correlated with the responsiveness to rest/sleep (RR/S) score and salivary cortisol concentration (P＜0.05), and the situation-specific fatigue subscale (SFS) scores of dimension 2 fatigue of FAI scale was negatively correlated with executive control network (P＜0.05).Conclusion The more fatigue of young soldiers, the higher saliva cortisol concentration, the lower executive control function.
