【摘要】：目的比较特情处置模拟飞行训练与起落航线飞行过程中心率及心率变异性的变化,探讨模拟飞行训练过程中飞行员心理应激水平的变化特点。方法随机选取参加飞行模拟训练训练的飞行员20名,连续动态记录心电信号,对其在安静时及起落航线飞行、特情处置飞行2种科目模拟飞行前、中、后的心率及短时程心率变异性时域及频域参数进行分析。结果 1)飞行前6 min,HR、RMSSD、LFnu及LF/HF升高,SDNN、HRVI降低(P0.05);飞行前特情飞行与起落飞行相比,RMSSD较低,LF/HF较高(P0.01)。2)飞行过程中HR和HRV各指标均出现升高(P0.05),各指标在2种科目之间无显著差异(P0.05);3)飞行后,各项指标均有所恢复,但未至安静时水平(P0.05)。特情处置飞行恢复较起落飞行更慢(P0.01)。结论飞行前发生应激反应并伴有较轻的心理疲劳,特情处置飞行前应激反应明显高于起落航线飞行;飞行中出现较高的心理反应及心理疲劳,但2科目间无明显差异;飞行后应激水平有所恢复,但特情处置飞行的恢复速度较起落飞行慢。
[Abstract]:Objective to compare the changes of heart rate (HR) and heart rate variability (HRV) between simulated flight training and flight course, and to explore the characteristics of psychological stress in pilots during simulated flight training. Methods Twenty pilots who participated in flight simulation training were randomly selected to record ECG continuously and dynamically. The time domain and frequency domain parameters of heart rate variability were analyzed. Results 1) 6 min,HR,RMSSD,LFnu and LF/HF increased before flight and the HRVI of SDNN decreased (P0.05), the HR and HRV increased during flight (P05), and there was no significant difference between the two subjects (P0.05) after flight (P05), and the RMSSD was lower than that in landing flight (P0.01). All the indexes recovered, but not to the quiet level (P0.05). The recovery of flight was slower than that of landing (P0.01). Conclusion stress reaction occurred before flight and was accompanied with mild mental fatigue. The stress response before flight was significantly higher than that on landing route, but there was no significant difference between the two subjects. The stress level recovered after flight, but the recovery rate of special disposal flight was slower than that of landing flight.
