本文主要就运动与活性氧的关系,特别是肌肉的活性氧生成和防御机制进行概述。 活性氧/自由基是在各种环境因子或细胞自身各种生理、病理过程中生成的。机体内生成活性氧和自由基主要部位是线粒体和微粒体的电子传递系统,黄嘌呤氧化酶(XOD)和花生酸代谢系统、嗜中性白细胞和巨噬细胞、膜土还原型磷酸尼克酰胺腺嘌呤二核苷酸(NADPH)氧化酶等。由于运动而生成活性氧/自由基也在这些部位,尤其以线粒体电子传递系统和XOD系统最重要。 This article focuses on the relationship between exercise and reactive oxygen species, especially the muscle reactive oxygen species production and defense mechanisms. Active oxygen / free radicals are generated in a variety of environmental factors or cells of various physiological and pathological processes. The main body of the body to generate reactive oxygen species and free radicals is the electron transfer system of mitochondria and microsomes, xanthine oxidase (XOD) and arachidonic acid metabolism systems, neutrophils and macrophages, membrane-bound phosphoacacamide Purine dinucleotide (NADPH) oxidase and the like. It is also at these sites that reactive oxygen species / free radicals are generated by exercise, especially mitochondrial electron transport systems and XOD systems.
