Abstract：
Commercial pilots endure multiple stressors in their daily and occupational lives which are detrimental to psychological well-being and cognitive functioning. The Quick coherence technique (QCT) is an effective intervention tool to improve stress resilience and psychophysiological balance based on a five-minute paced breathing exercise with heart rate variability (HRV) biofeedback. The current research reports on the application of QCT training within an international airline to improve commercial pilots\' psychological health and support cognitive functions. Forty-four commercial pilots volunteered in a one-month training programme to practise self-regulated QCT in day-to-day life and flight operations. Pilots\' stress index, HRV time-domain and frequency-domain parameters were collected to examine the influence of QCT practice on the stress resilience process. The results demonstrated that the QCT improved psychophysiological indicators associated with stress resilience and cognitive functions, in both day-to-day life and flight operation settings. HRV fluctuations, as measured through changes in RMSSD and LF/HF, revealed that the resilience processes were primarily controlled by the sympathetic nervous system activities that are important in promoting pilots\' energy mobilization and cognitive functions, thus QCT has huge potential in facilitating flight performance and aviation safety. These findings provide scientific evidence for implementing QCT as an effective mental support programme and controlled rest strategy to improve pilots\' psychological health, stress management, and operational performance.
摘要：
商业飞行员在日常生活和职业生活中承受着多种压力，这不利于心理健康和认知功能。快速相干技术（QCT）是一种有效的干预工具，可基于具有心率变异性（HRV）生物反馈的五分钟节奏呼吸运动来改善压力弹性和心理生理平衡。当前的研究报告了在国际航空公司中应用QCT培训以改善商业飞行员的心理健康并支持认知功能。44名商业飞行员自愿参加了为期一个月的培训计划，在日常生活和飞行操作中练习自我调节的QCT。飞行员压力指数，收集HRV时域和频域参数，以检查QCT练习对应力弹性过程的影响。结果表明，QCT改善了与压力弹性和认知功能相关的心理生理指标，在日常生活和飞行操作设置中。HRV波动，通过RMSSD和LF/HF的变化来衡量，揭示了弹性过程主要由交感神经系统活动控制，这对促进飞行员的能量动员和认知功能很重要，因此，QCT在促进飞行性能和航空安全方面具有巨大潜力。这些发现为实施QCT作为有效的心理支持计划和控制休息策略以改善飞行员的心理健康提供了科学依据。压力管理，和运营绩效。
