生理学家将人在肌肉活动中出现的肌肉功能性工作能力减弱(或工作量降低)以至完全丧失的现象叫做疲劳。虽然疲劳产生的机制目前尚未十分清楚,但学者们普遍地认为,“在整体情况下,中枢神经系统的功能状态是影响疲劳的产生与发展的重要因素”,“疲劳时神经系统的机能下降”。“近年来测定疲劳时脑电及肌电图的变化为各国学者所重视”。查阅国内有关疲劳机制的研究文献,发现在研究方法上,运用较多的生理指标仍为心电图、肌电图、呼吸肌耐力和视觉闪烁临近融合频率等,疲劳的大脑皮层电活动的研 Physiologists will appear in the muscle activity of muscle weakening of the functional ability to work (or reduce the workload) as well as the total loss of the phenomenon known as fatigue. Although the mechanism of fatigue is not well understood at present, scholars generally believe that “in the overall situation, the functional status of the central nervous system is an important factor that affects the generation and development of fatigue” and “the decline of the nervous system during fatigue” . “In recent years, determination of fatigue and electroencephalogram EEG changes for the attention of scholars from all countries.” See the domestic research literature on fatigue mechanism, found that in the research methods, the use of more physiological indicators are still electrocardiogram, electromyography, respiratory muscle endurance and visual scintigraphy near the fusion frequency, fatigue, the study of the electrical activity of the cerebral cortex
