Iron Supplementation Improves Energetic Efficiency During Submaximal Exercise in Iron Deficient Non-anemic Women (P24-042-19)

Objectives It has been estimated that 37–50% of anemia in non-pregnant women of reproductive age (WRA) is associated with iron deficiency (ID). Some of the highest rates of anemia associated with ID have been found in Latin American and Caribbean countries including Mexico. It has been well established that iron deficiency anemia (IDA), characterized by a reduced concentration of hemoglobin, results in a decline in muscular work capacity exhibited by a decrease in aerobic capacity and the ability to perform physical exercise. There is conflicting evidence on the impairment of physical work capacity in the iron deficient non-anemic (IDNA) state that is characterized by low serum ferritin but normal hemoglobin. The purpose of this study was to determine if iron status influences physical work capacity during submaximal exercise in Mexican women 18- to 45-year-old who are marginally iron depleted but not anemic.
