What are antioxidants?
Antioxidants neutralize free radicals by supplying missing electrons or removing an extra one to restore stability. In our body, we have our own antioxidant enzymes but the important micronutrient antioxidants are vitamin E, beta-carotene, and vitamin C. In addition, selenium, a trace metal, is needed for the formation of the enzyme glutathione in the defense against free radicals. These micronutrients cannot be manufactured by our body; we need to have a balanced diet to obtain these vitamins
Exercise and free radicals
When you exercise, your oxygen intake increases by 10 to 20 times over the resting state. This greatly increases the number of free radicals. However, regular physical exercise promotes the antioxidant defense system and protects against free radicals induced by exercise. On the other hand, vigorous exercise, once in while, induces damage to antioxidant defenses resulting in increased free radical damage.
