目的分析高性能战斗机飞行员特技飞行时的心率、心率变异性等指标的变化,研究高性能战斗机飞行员的飞行劳动特点. 方法使用“飞行员飞行生理参数记录检测仪”(简称生参仪),记录10名健康男性高性能战斗机飞行员在17架次特技飞行过程中的心电信号,分析飞行员心率、心率变异性(heart rate variability,HRV)的变化特点. 结果特技动作时飞行员的平均心率和最大心率分别为(92.3±13.2)次/min和(101.2±15.9)次/min,明显高于其他飞行阶段(F=58.479、35.209,P＜0.01).代表交感迷走神经平衡性的HRV指标低频高频比值在特技动作时明显增高,与其他飞行阶段比,差异有统计学意义(F=19.893,P＜0.01). 结论特技飞行时高性能战斗机飞行员心率和交感神经调节明显增高,提示飞行员体力和脑力负荷增加.

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.
