Summary

It is very common for the bodies of endurance athletes to be deficient in iron. In particular female athletes often have this problem. Even moderately low levels of exercise can also cause this problem. Associate Professor Roseanne M. Lyle carried out a study on 62 formerly inactive females. Her work indicated that such women showed a decrease in iron levels. Some women bounced back with the consumption of additional meat or the


supplementation of their diets with ironsupplements . Iron deficiency affects many

women. The ratio of exercising women with this deficiency, however, is far higher. This is made worse by health- conscious women who often eat a restricted diet which is not iron rich enough. Women do not usually eat the recommended daily allowance of iron. Any additional exercise may have caused women to be tipped over the edge causing serious iron deficiency.
