机体运动过程中产生的活性氧与运动强度成正比,过多量的活性氧会造成运动损伤以及多种疾病的产生,但一定量的活性氧又是机体代谢所必需的。活性氧调节细胞的分化、增殖、凋亡以及基因表达,本文就近年来有关运动过程中活性氧的产生途径、可能的生理作用以及清除体系做了综述报道。 Active oxygen generated during body movement is proportional to exercise intensity. Excessive amount of active oxygen can cause sports injuries and a variety of diseases. However, a certain amount of active oxygen is necessary for body metabolism. Active oxygen regulates the differentiation, proliferation, apoptosis and gene expression of the cells. In this paper, we reviewed recent reports on the production of reactive oxygen species (ROS) and their possible physiological roles in the process of exercise.
