Exhaustive exercise can induce excessive generation of reactive oxygen species (ROS), which may enhance oxidative stress levels. Although physiological levels are crucial for optimal cell signaling and exercise adaptations, higher concentrations have been demonstrated to damage macromolecules and thus facilitate detrimental effects. Besides single dosages of antioxidants, whole diets rich in antioxidants are gaining more attention due to their practicality and multicomponent ingredients. The purpose of this narrative review is to summarize the current state of research on this topic and present recent advances regarding the antioxidant effects of whole dietary strategies on exercise-induced oxidative stress in humans. The following electronic databases were searched from inception to February 2021: PubMed, Scope and Web of Science. Twenty-eight studies were included in this narrative review and demonstrated the scavenging effects of exercise-induced ROS generation, oxidative stress markers, inflammatory markers and antioxidant capacity, with only one study not confirming such positive effects. Although the literature is still scarce about the effects of whole dietary strategies on exercise-induced oxidative stress, the majority of the studies demonstrated favorable effects. Nevertheless, the protocols are still very heterogeneous and further systematically designed studies are needed to strengthen the evidence.
力竭运动可诱导活性氧（ROS）过度生成，这可能会提高氧化应激水平。虽然生理水平的ROS对于最佳细胞信号传导和运动适应至关重要，但已证明较高浓度的ROS会损害大分子，从而产生有害影响。除了单一剂量的抗氧化剂外，富含抗氧化剂的完整饮食因其实用性和多成分特性而受到越来越多的关注。本叙述性综述的目的是总结该主题的当前研究现状，并介绍关于完整饮食策略对人类运动诱导的氧化应激的抗氧化作用的最新进展。从创刊至2021年2月检索了以下电子数据库：PubMed、Scope和科学网。本叙述性综述纳入了28项研究，这些研究证明了完整饮食策略对运动诱导的ROS生成、氧化应激标志物、炎症标志物和抗氧化能力的清除作用，只有一项研究未证实这种积极作用。尽管关于完整饮食策略对运动诱导的氧化应激影响的文献仍然稀少，但大多数研究显示出有利影响。然而，研究方案仍然非常不一致，需要进一步进行系统设计的研究来加强证据。
