疲劳问题是运动生理学和运动生物化学的重要研究问题之一。运动性疲劳是指机体在体育运动中,由于长时间肌肉紧张活动而出现的一种状态。客观上表现为运动能力的下降,主观上伴有精神疲乏的感觉,而这种感觉往往是不符合机体疲劳产生的时间和程度的。根据疲劳抑制过程的不同,许多学者将疲劳分为中枢与外周两种既区别又相互联系的类型,当机体进行短时间剧烈运动时所出现的疲劳,是以肌肉中三磷酸腺苷等能源物质消耗、血液中乳酸堆积等外周因素为主;而长时间中等强度的肌肉运动产生的疲劳则以中枢神经
The fatigue problem is one of the important research issues in exercise physiology and exercise biochemistry. Sports fatigue refers to the body in sports, due to prolonged muscle tension and a state of activity. Objectively manifested as decreased exercise capacity, subjective mental fatigue associated with feeling that often do not meet the body fatigue and the time and extent of the. According to the different process of fatigue suppression, many scholars classify fatigue into two kinds of central and peripheral types that are both distinct and interrelated. When the body undergoes strenuous exercise for a short period of time, the fatigue occurs because energy consumption of muscle such as adenosine triphosphate, blood In the lactic acid accumulation and other peripheral factors; and long-term moderate-intensity muscle exercise fatigue is the central nervous system
