Daily iron supplementation significantly improves maximal and submaximal exercise performance in WRA , providing a rationale to prevent and treat iron deficiency in this group .
Animal and human observational studies suggest that iron deficiency impairs physical exercise performance , but findings from r and omized trials on the effects of iron are equivocal .
Iron deficiency and anemia are especially common in women of reproductive age ( WRA ) .
Clear evidence of benefit from iron supplementation would inform clinical and public health guidelines .
Therefore , we performed a systematic review and meta- analysis to determine the effect of iron supplementation compared with control on exercise performance in WRA .
The effects of hemoglobin supplements on maximal oxygen uptake in females.
There was no significant change in the maximal oxygen uptake for either the experimental or the control group from the pre-test to the post-test . Five blood chemistry measures were unable to predict the post-maximal oxygen uptake scores using the procedure of stepwise regression . An examination of the blood chemistry profiles indicated that sports anemia did not occur . The factorial breakdown was unable to produce any significant insight into the changes in hemoglobin concentration and oxygen consumption .  Heme-iron supplementation was unable to override the regulatory system of the body and allow the hemoglobin level to become elevated
