Abstract：Objective To analyze the changes in indicators of heart rate variability of pilots and cadets before,during,and after flights in order to provide data for analysis of psychological stress and for safety assurance during flight training.Methods Forty-two male pilots and cadets were selected for collection of physiological data during flights,with electrocardiogram(ECG)parameters recorded.Results The differences in heart rate,low frequency(LF),high frequency(HF),and the ratio of low to high frequency(LF/HF)of pilots during non-training periods and before,during,and after flight training were statistically significant(F=4.791～31.909,P＜0.05).During daily flight training,heart rate,LF,and LF/HF of pilots increased(P＜0.001,=0.001,0.004)while HF decreased(P=0.001).The differences in the standard deviation of normal-to-normal intervals(SDNN)and the root mean square of successive differences of RR intervals(RMSSD)before,during and after flight training between cadets were also of statistical significance(F=6.479,8.005;P=0.005,0.002).During daily flight training,the RMSSD decreased(P=0.008).Conclusion The heart rate and frequency domain indicators of pilots change significantly during flight training,so do the time domain indicators of cadets,which can provide a reference for aviation health and safety assurance of pilots and flight cadets during flight training.
