摘要
大量科学研究表明 ,规律性的身体活动能促进人体健康 ,延长寿命。身体活动有助于健康寿命的一种可能性机制是 ,可增加机体的抗氧化能力。本文的目的是 ,综述身体活动、抗氧化剂与健康寿命有关的研究成果。这些研究成果表明 ,许多抗氧化剂都与死亡率呈负相关。一次性适宜运动可增加一些抗氧化酶和辅酶的活性 ,经常规律性的身体活动可增强机体抗氧化系统 ,而急性剧烈运动则会降低机体抗氧化能力。这表明 ,在身体活动对健康寿命的积极影响方面 。
Scientific studies show that regular physical activity enhances health and life.A possible mechanism by which physical activity contributes to health and life is via enhanced antioxidant status.The purpose of this paper is to review the findings on physical activity,antioxidant,health and life.It has been shown that several antioxidants have been inversely correlated with mortality.A single bout of exercise elevates some antioxidant enzyme and coenzyme activities.Regular physical activity enhances some antioxidants.However,strenuous exercise may diminish others.Results of many studies imply that antioxidants may play a mediating role in the way in which physical activity positively affects health and life.
