摘要
疲劳是一个复杂的过程,受体内多种因素的影响。百年来,人们从不同角度去研究疲劳,但对运动性疲劳发展过程各阶段的不同变化的研究的直接观测证据目前仍未见到。1992年9月成都体院疲劳研究组提出了运动性疲劳发展过程的理论,把疲劳看成是一个发展的过程,划分为开始阶段、增强阶段、力竭阶段。本文拟通过对大白鼠在不同负荷条件下游泳导致疲劳发展过程的增强阶段和力竭阶段的取样,用光镜和电镜观察疲劳过程不同阶段所引起的股直肌的组织学特征的变化,以及测定不同阶段的乳酸值的变化来比较疲劳过程的阶段性特征。
Fatigue is a complex process, it is affected by many factors. From a hundred years ago. people have studied fatigue from different angles. But the direct observe evidenc of the study Which are about the different changes in the various stages of the exercise-fatigue development have not been seen. In 1992, 9, the fatigue research group of chengdu physical education put forward the theory of exercise-fatigue development process, they thought the fatigue as a development process, devided it into start、enhance, and exhaustion stage. So this text will compare the stage facture of the fatigue process through the sampling of the enhance and exhaustion stage in the fatigue—development process which was led by swimming, by the changes which were observed under the light-microscopy and tele microcopy of the histology-facture-changes of the rectus femoris in the different stages of the fatigue process, and by determining the changes of lactic acid value in different stages.
