我们对6名男性进行了最大运动试验，使用自行车测力计，然后测量血浆中的铁还原能力，以澄清抗氧化状态和运动强度之间的关系。铁还原能力随运动强度的增加呈直线增加，而羟自由基的产生随运动强度的增加呈下降趋势。此外，羟自由基的产生与血浆中乳酸水平呈对称相关。这些结果表明，抗氧化能力的增强与运动强度的增加，乳酸水平，这增加了体育锻炼，可以作为一种清除剂的自由基。
We performed maximal exercise tests on 6 men using a bicycle ergometer and then measured the ferric-reducing ability in plasma to clarify the relationship between antioxidant status and exercise intensity. The ferric-reducing ability showed a rectilinear increase with the increase in exercise intensity, whereas the generation of hydroxyl radicals showed a decrease with the increase in exercise intensity. Also, the generation of hydroxyl radicals showed a symmetrical correlation to lactate level in plasma. These results suggest that antioxidant ability is enhanced with an increase in exercise intensity, and that the lactate level, which increases with physical exercise, may act as a scavenger of free radicals.
