【摘要】：目的探讨飞行学员首次单飞条件下心率(heart rate,HR)、心率变异性(heart rate variability,HRV)的变化特点,为飞行学员的选拔和训练提供方法和生理学依据。方法随机选取海军飞行学员20名,在首次单飞前日佩戴飞行员生理参数记录检测设备,连续动态记录安静状态下30 min的心电信号,在首次单飞当天佩戴飞行员生理参数记录检测设备,动态记录首次单飞时的心电信号,采用与记录检测设备配套的数据分析系统对HR、HRV指标进行分析,对安静状态和首次单飞状态下测量的结果进行比较对照(方差分析)。结果 (1)飞行学员在首次单飞时HR指标(66.744±7.334)较安静状态(57.916±2.105)明显增高(P0.05);(2)首次单飞时飞行学员HRV的频域指标低频、高频(84.993±7.193、8.255±4.434)较安静状态(72.585±11.821、3.412±1.551)明显增高(P0.01),而高频指标首次单飞时(13.125±5.844)较安静状态(25.764±11.237)明显降低(P0.01)。结论飞行学员在首次单飞过程中出现自主交感神经兴奋,副交感神经降低,表明,首次单飞时飞行学员容易出现应激反应,可进行有效干预。
[Abstract]:Objective to investigate the changes of heart variability (HR) and (heart rate variability (HRV) in flight cadets under the condition of first solo flight, and to provide methods and physiological basis for the selection and training of flight cadets. Methods A total of 20 naval cadets were randomly selected to wear the pilot physiological parameters recording and detecting equipment on the day before the first single flight. The ECG signals of 30 min in the quiet state were recorded continuously and dynamically. On the day of the first solo flight, the pilot's physiological parameters were recorded and the ECG signal was recorded dynamically. The HRV index was analyzed by the data analysis system matching with the recording and detecting equipment. The results were compared between the quiet state and the first single flight state (ANOVA). Results (1) HR (66.744 卤7.334) was significantly higher than that in quiet (57.916 卤2.105) in the first flight (P0.05); (2). The high frequency (84.993 卤7.193 卤8.255 卤4.434) was significantly higher than that in quiet (72.585 卤11.821) 3.412 卤1.551 (P0.01), and the high frequency index (13.125 卤5.844) was significantly lower than that in quiet (25.764 卤11.237). Conclusion during the first solo flight, the autonomous sympathetic nerve excited and the parasympathetic nerve decreased, which indicated that the flight cadets were prone to stress reaction during the first solo flight and could intervene effectively.
