Supplemental Iron Improves Submaximal Exercise Performance in Non-anemic Iron Depleted Women

Plain-language summary

The specific aims of the current study were: 1) To determine the prevalence of IDNA in a sample of Mexican women of reproductive age and 2) To determine how iron supplementation in IDNA women influences physical work capacity during submaximal exercise . The researchers hypothesized that marginally iron depleted women will have improved physical work capacity during submaximal intermittent exercise tests after dietary iron supplementation. However, no improvement in peak maximal oxygen consumption after dietary iron supplementation because they will remain non-anemic.
