Iron supplementation improves endurance after training in iron-depleted, nonanemic women.
Our objective was to investigate the effects of iron depletion on adaptation to aerobic exercise, assessed by time to complete a 15-km cycle ergometer test. Forty-two iron-depleted (serum ferritin <16 microg/l), nonanemic (Hb >12 g/dl) women (18-33 yr old) received 100 mg of ferrous sulfate (S) or placebo (P) per day for 6 wk in a randomized, double-blind trial. Subjects trained for 30 min/day,...
متن کاملEffect of Zinc on Efficacy of Iron Supplementation in Improving Iron and Zinc Status in Women
Iron and zinc may interact in micronutrient supplements and thereby decrease efficacy. We investigated interactive effects of combined zinc and iron supplementation in a randomized controlled trial conducted in 459 Guatemalan women. Four groups were supplemented for 12 weeks: (1) weekly iron and folic acid (IFA); (2) weekly IFA and 30 mg zinc; (3) daily IFA; (4) daily IFA and 15 mg zinc. Effect...
متن کاملEffect of iron injections on aerobic-exercise performance of iron-depleted female athletes.
This investigation examined the effect of intramuscular iron injections on aerobic-exercise performance in iron-deficient women. Sixteen athletes performed a 10-min steady-state submaximal economy test, a VO2max test, and a timed test to exhaustion at VO2max workload. Subjects were randomly assigned to an iron-supplemented group (IG) receiving intramuscular iron injections or to a placebo group...
متن کاملObesity and Iron Status in Women of reproductive age
Abstract Background and Objectives: Women of reproductive age are at risk of Iron deficiency. Some Studies reported That There is a relationship between Body indices and iron. Iron overload is also harmful. It enhances the risk of cardiovascular disease which is due to increased Lipid peroxidation. The aim of this study was to investigate the relationship between obesity and iron status in wome...
متن کاملAltered metabolic response of iron-depleted nonanemic women during a 15-km time trial.
In this double-blinded study, 37 women with iron depletion without anemia (age 19-36 yr) were randomly assigned to receive either an iron supplement (135 mg/day) or a placebo. Endurance capacity was assessed during a 15-km simulated time trial (TT) on a cycle ergometer before and after the 8-wk treatment. After the treatment, although the iron-supplemented group did not have shorter time to fin...
