Abstract:
Objective To investigate the effect of aerobatic flight on high performance fighter pilots' physiological characteristics and to analyze their work loads in such flight.Methods Ten healthy male military pilots executed 17 aerobatic flights.Electrocardiograph was recorded during flight,and heart rate (HR) and heart rate variability (HRV) were analyzed.Results During aerobatic flight,HR and HRV showed increasing sympathetic nerve regulation.The mean HR,max HR at aerobatic stage was (92.3 ±13.2),(101.2 ±15.9) beats / min and significantly higher than those in other stages respectively(F=58.479,35.209; P＜0.01).The ratio of LF and HF (LF/HF) significantly increased in aerobatic stage,and the difference with that in acrobatic stages were statistic meaning(F=19.893,P＜0.01).Conclusions High performance fighter pilots endure high G and high G onset in aerobatic flight.The increasing sympathetic nerve regulation indicates pilot's high physical and mental workload.
