Genetic Variation that Regulates Iron Metabolism May Enhance Endurance Performance in Athletes

Medical News

A genetic variation that regulates iron metabolism may enhance athletes' endurance performance, researchers at the University of Toronto have shown.

The findings could help explain studies that show an association between the genetic variation and elite athletes across many sports and may help competitive athletes fine-tune their iron intake to boost performance.

The variation, found in the homeostatic iron regulator (HFE) gene, is a known cause of iron overload, a condition called hemochromatosis in which the body absorbs too much iron leading to organ and joint damage.

Athletes at risk for hemochromatosis but with iron stores below potentially ...
