摘要
疲劳是由长时间的体力和脑力劳动所导致的一种身心疲惫状态,亦是降低工作绩效、诱发工伤事故的重要因素之一。疲劳会导致注意力不集中、工作绩效下降,诱发慢性疾病,长期疲劳还会危及生命安全。在大部分高负荷工作任务与复杂场所环境下人的疲劳是由脑力疲劳和体力疲劳共同所致。因此研究体脑疲劳交互影响及神经生理机制有重要的科学意义与应用价值。本文介绍了近几年有关体、脑疲劳方面的研究情况,并归纳了体脑疲劳交互影响机制研究的初步进展,总结了目前存在的研究难点与未来可能的发展方向。体脑疲劳的相互影响可能发生在中枢神经系统,揭示基底神经节功能及多巴胺释放规律可能是解读体脑疲劳交互影响神经机制的关键;今后还需要在疲劳诱发实验设计优化、检测评价参数优选和体脑疲劳神经建模等方面做深入研究,以为复杂工作任务设定提供科学依据和理论指导,为疲劳监测、疲劳对抗提供科学方法和技术支撑。
Fatigue is an exhaustion state caused by prolonged physical work and mental work, which can reduce working efficiency and even cause industrial accidents. Fatigue is a complex concept involving both physiological and psychological factors. Fatigue can cause a decline of concentration and work performance and induce chronic diseases. Prolonged fatigue may endanger life safety. In most of the scenarios, physical and mental workloads co-lead operator into fatigue state. Thus, it is very important to study the interaction influence and its neural mechanisms between physical and mental fatigues. This paper introduces recent progresses on the interaction effects and discusses some research challenges and future development directions. It is believed that mutual influence between physical fatigue and mental fatigue may occur in the central nervous system. Revealing the basal ganglia function and dopamine re- lease may be important to explore the neural mechanisms between physical fatigue and mental fatigue. Future effort is to optimize fatigue models, to evaluate parameters and to explore the neural mechanisms so as to provide scientific basis and theoretical guidance for complex task designs and fatigue monitoring.
