Abstract：Objective To explore the heart rate(HR),moods and changes of indicators of heart rate variability(HRV)of fighter pilots during simulated training for ejection survival in order to provide data for well-designed and effective training.Methods The changes in electrocardiograms(ECGs),moods,and blood pressure before and after training among 36 fighter pilots were recorded during two sessions of simulated training for ejection escape and across three phases of ejection(pre-ejection,during ejection,and post-ejection).For ECG data,HRV was recorded,including the standard deviation of normal R-R intervals(SDRR),total power(TP),low frequency(LF),high frequency(HF)and HR.The results of the questionnaire were analyzed.Results In the first session of ejection escape training,only 13.89%of the pilots were rated as excellent,and one pilot failed the training.In the second session,the excellent rate was 83.33%,and the results of training evaluation were all good or better.Analysis of changes in HR and moods before,during and after the two ejection escape training sessions suggested that in the second ejection survival training session,72.22%of the subjects scored lower than 3 points in terms of stress while 91.67%scored 4 points or higher in confidence.The difference was not statistically significant(P＞0.05).The results of repeated measures analysis of variance of the changes of HRV before,during and after the two sessions showed that there were statistically significant differences in the subjects'HRV,including SDRR(H=41.016,P＜0.001),TP(H=50.265,P＜0.001),and LF(H=6.316,P=0.006)across training stages.Conclusion Simulated training for ejection escape is effective in improving pilots'emergency response and increasing their confidence during ejection escape.
