| 中文摘要: |
| 自由基代谢普遍存在于机体各组织。正常情况下，人体自由基的产生与清除处于平衡状态。而人体自由基产生过多或机体
清除自由基能力下降将给机体带来损伤。本文采用文献资料法，阐述了自由基的类型、功能、自由基产生的机制以及抗氧化系统
的种类等基本理论。通过对力竭运动、耐力运动和无氧运动3 种不同形式的运动对自由基代谢及抗氧化酶活性的研究得出结论：
不同的运动形式及负荷方式对体内自由基代谢及抗氧化酶活性将产生不同影响；运动对自由基代谢影响具有器官与组织差异
性。这些研究成果为科学指导运动训练和健身活动、快速有效的消除运动性疲劳并增强运动能力提供重要的科学理论依据。 |

| Free radical metabolism exists widely in many tissues. Under the normal situation, production and clearance of the
free radical is in the equilibrium state. When the production of free radicals increases and tissues fail to remove it, cellular biomolecules
will be damaged. By using the method of documentation, the thesis sets forth the basic theories, such as the type, function, mechanism of
free radical production and the category of the antioxidant system, and etc. The paper summarized the research achievements and
discussed separately in recent years. By analyzing the currently research conditions of the three different kinds of sport (exhaustive
exercise, endurance exercise, anaerobic exercise) to the metabolism of the free radicals and the activity of the antioxidant enzymes, we
can make conclusions: the different sport forms influence the metabolism of the free radicals and the activity of antioxidant enzymes in
body in the process of exercise. The different load modes of motion has different influences to the free radical metabolism. And it is
different for effects of exercise on the metabolism of free radicals in the different organs and tissues. In order to provide the scientific
theory basis to guide sports training and exercises to keep in good health, to eliminate exercise-induced fatigue and enhance exercise
ability, the author gave some suggestions. |
