金属长期暴露于空气中会生锈,这是氧化作用的结果。人体时刻需要氧气,但在吸入氧气的过程中,人体也会“生锈”。人体内的“锈”:氧自由基人体在正常代谢过程中会产生少量的氧自由基,对身体无害。但如果人体代谢过程中某个环节出现异常或者由于其他原因致使细胞分裂和氧化需求加快,比如体力负担突然成倍增加,就会产生过多的氧自由基,使肌肉组织受到伤害。
Long-term metal exposure to the air rust, which is the result of oxidation. The human body needs oxygen all the time, but in the process of inhaling oxygen, the human body will also “rust”. Human body “rust ”: oxygen free radicals in the normal metabolism of human body will produce a small amount of oxygen free radicals, harmless to the body. However, if the human metabolism in some part of abnormal or due to other reasons led to cell division and the accelerated demand for oxidation, such as sudden increase in physical burden doubled, it will produce too much oxygen free radicals, muscle tissue damage.
