It is well known that a training intervention leads to mitochondrial adaptations with increased skeletal muscle mitochondrial biogenesis and function. Studies have recently indicated that skeletal muscle mitochondrial function is important for athletic performance. During exercise reactive oxygen species are released from skeletal muscle potentially leading to adaptations but maybe also to fatigue. Focus has been on how chronic antioxidant supplementation affects a training adaptation, where some studies are reporting an abolished adaptation. Whether acute antioxidant supplementation could have a positive effect on fatigue and performance is interesting and highly relevant in sports where athletes are competing over several consecutive days or on the same day, with preliminary competitions in the morning and finals in the afternoon, where it is important for the athletes to recover fast. This review provides an overview of the effects of acute antioxidant supplementation and whether it leads to improved performance and/or faster recovery in humans.
众所周知，训练干预会导致线粒体适应，增加骨骼肌线粒体生物发生和功能。最近的研究表明，骨骼肌线粒体功能对运动表现很重要。在运动过程中，活性氧从骨骼肌中释放出来，可能导致适应，但也可能导致疲劳。人们关注的焦点是慢性抗氧化剂补充如何影响训练适应，一些研究报告称这种适应被消除了。急性抗氧化剂补充是否会对疲劳和表现产生积极影响，这在运动员需要连续几天或同一天参加多场比赛的运动中非常有趣且非常重要，在这些比赛中，运动员需要快速恢复。本文综述了急性抗氧化剂补充的作用，以及它是否能提高人类的运动表现和/或更快恢复。
