Abstract:
Objective To investigate the effects of high intensity flight on physiological indices and subjective evaluation of flight work load of high performance fighter pilot.Methods Five healthy male military pilots executed 22 high intensity flights in one day.Electrocardiograph was recorded during flight,and heart rate and heart rate variability (HRV) were analyzed.Flight work load and subjective fatigue feeling were evaluated by pilots themselves.Results During high intensity flight,heart rate and HRV showed an apparent circadian rhythm.Heart rate,low frequency normalized unit (LFnu) and ratio of low and high frequency (LF/HF)in night time were lower than those in day time,but high frequency normalized unit (HFnu).There was no obvious subjective fatigue feeling commented by pilots.Conclusions High intensity flight of high performance fighter pilots has some effects on physiological indices,but no flight fatigue so far.Rational disposition of flight and adequate aeromedical support could be beneficial to pilot's recovery and the alleviation of flight fatigue.
