军事飞行人员自主神经稳定性训练应用研究

Effect of Autonomic Nervous Stability Training on Military Flight Personnel

目的探讨军事飞行人员自主神经稳定性训练的效果,为进一步的应用和研究提供依据。方法 50名军事飞行人员为研究对象,随机分为两组,分别为试验组(n=26)和对照组(n=24)。采用模拟飞行作为任务情境,在训练前采集全部人员完成任务情境的心率变异性(heart rate variability,HRV)时域、频域等指标,试验组学习并掌握自主神经稳定性训练,对照组则采用自我呼吸调节训练代替,之后两组在任务情境下使用学习到的训练方法,同时采集上述各指标数据。试验组并填写训练效果评估问卷,对全部数据进行组间和组内分析评估训练效果。结果 (1)HRV时域指标:训练前后两组间和组内均无显著性差异(P>0.05);(2)HRV频域指标:训练前两组间无显著性差异(P>0.05);与对照组及自身训练前相比,试验组0.1Hz指数、LF、LF/HF有明显增高(P<0.05,P<0.01);与自身训练前相比,试验组TP、LFnorm有明显增高,VLF、HFnorm则有明显下降(P<0.05,P<0.01);对照组LF/HF与自身训练前相比有升高(P<0.05);(3)自主神经稳定性训练效果评估问卷显示训练的必要性和有效性均为92%。结论自主神经稳定性训练可以有效调节军事飞行人员交感-迷走神经功能的平衡,有助于保持良好的工作绩效。

Objective To investigate the effect of autonomic nervous stability training on military flight personnel in order to provide data for future applications and studies.Methods Fifty military pilots were randomly divided into the experimental group(n=26)and control group(n=24).The indexes of HRV(time domain and frequency domain)in completing the flight simulation task were measured before training.Autonomic nervous stability training was performed in the experimental group for 30 minutes while respiratory training of the same length was performed in the control group.The indexes of HRV of each pilot in completing the flight simulation task were measured a second time.The experimental group completed the training assessment questionnaire and the effect of training was analyzed.Results(1)HRV time domain indexes:there was no significant difference between or within the two groups after training.(P>0.05).(2)HRV frequency indexes:there was no significant difference between the two groups before training(P>0.05).Compared with the control group,the experimental group gained a significant increase in 0.1Hz,LF and LF/HF(P<0.05,P<0.01)after training.The experimental group gained a significant increase in TP and LFnorm,but a significant decrease in VLF and HFnorm(P<0.05,P<0.01)after training.After training,the control group gained a significant increase in LF/HF(P<0.05).(3)The necessity and effectiveness of autonomic nervous stability training was 92%according to the result of the training assessment questionnaire.Conclusion The autonomic nervous stability training can effectively regulate the balance of sympathetic-vagus nerve function in military flight personnel while helping maintain good work performance.
