中文摘要:

运动过程中骨骼肌产生的高水平反应物会导致肌肉损伤和肌肉功能受损，一般认为补充抗氧化剂可以保护肌肉不受损伤。无论对于运动爱好者还是专业运动员，抗氧化剂都是最常用的运动补剂之一。目前备受关注的是用额外口服抗氧化剂的方法来支持内源性防御系统，从而实现预防或减轻氧化应激、减少肌肉损伤并改善运动表现。目前有大量已发表的研究对该主题进行了讨论，大多数研究表明，抗氧化剂可以减轻运动引起的氧化应激，但大多数研究都未发现其对肌肉损伤和肌肉功能有任何影响。此外，越来越多的证据表明，抗氧化剂对健康和训练适应有消极作用。本文深入分析总结了关于活性物质（Reactive Species）在体内的作用以及服用抗氧化剂对维持健康和提高身体性能的功效的文献。

英文摘要:

High levels of reactive species produced in skeletal muscle during exercise have been associated with muscle damage and impaired muscle function, whereas antioxidants are seen as the defense against these threats. Antioxidants are among the most common sports supplements used by amateur and professional athletes. Supporting endogenous defense systems with additional oral doses of antioxidants has received much attention as a strategy to prevent or reduce oxidative stress, decrease muscle damage, and improve exercise performance. There have been numerous studies published on this topic. A majority of the studies demonstrated that antioxidant supplementation would attenuate exercise-induced oxidative stress, yet most of them reported no effects on muscle damage and performance. Moreover, a growing body of evidence indicates detrimental effects of antioxidant supplementation on health and training adaptations. This review provides an in-depth review of literature concerning the role reactive species play in the body and the efficacy of taking antioxidant supplementation for maintaining health and enhancing performance.
