Abstract：Objective To investigate heart rate variability(HRV)of flying cadets during simulated flight missions in order to provide data for physiological assessment during psychological selections of flying cadets.Methods Sixty-three pilot candidates participating in the psychological selection in 2023 were selected,who were asked to wear ear clip-type HRV signal collectors from the"stability assessment system for the autonomic nervous system"and had their HRV monitored three times(five minutes each time)before,during,and after the simulated flight mission.And conducted data analysis.Results The time-domain indicators root mean square of successive differences and percentage of adjacent NN intervals differing by more than 50 milliseconds were higher before and after the mission than during the mission(all P＜0.05),while mean heart rate turbulence and standard deviation of heart rate turbulence were lower before and after the mission than during the mission(all P＜0.001).The frequency-domain indicators total power,low frequency,low frequency/high frequency ratio and 0.1 Hz frequency band power were lower before and after the mission than during the mission(all P＜0.05),while high frequency were higher before and after the mission than during the mission(both P＜0.001).Conclusion During high-difficulty simulated flight missions,the activity of the sympathetic nervous system in pilot candidates increases,while that of the parasympathetic nervous system decreases.
