对运动性疲劳的研究虽已有一百多年的历史,但对其本质的认识仍不统一。目前多数学者认为:运动性疲劳是人在运动时,机体生理过程不能持续其机能在一特定的水平上,或各器官不能维持预定的运动强度。运动性疲劳的发生从中枢到骨骼肌细胞、再到细胞内的物质能量代谢过程,中间任何一个环节或这些过程综合变化,都可以造就疲劳。在一定范围内,疲劳的程度越大,超量恢复就越明显,一旦超过了这一范围,就会变为过度疲劳。因
Although the study of exercise-induced fatigue has a history of over one hundred years, its understanding of its essence is still not uniform. At present, most scholars believe that: exercise fatigue is the human body during exercise, the body’s physiological processes can not continue its function at a specific level, or each organ can not maintain the predetermined exercise intensity. Exercise fatigue occurs from the central to skeletal muscle cells, and then to the energy metabolism of the material process in the middle of any link in the middle or a combination of these changes, can create fatigue. Within a certain range, the greater the degree of fatigue, the more obvious the excess recovery, once beyond this range, it will become over-tired. because
