Description
Anna Tobiasch and co-authors show that a long mountain race can starve tissues of iron for a while. Iron fuels cell energy making, but the body locks it away when inflammation flares. Seven elite runners gave blood before and after a world title trail race in Austria. The course ran close to ninety kilometers with huge climbs.
After the race, alarm signals and the iron locking hormone both rose. Free iron in the blood fell, even as stored iron read high. Signs of burst red cells showed too. Gene readings in blood cells matched a state of iron want: more uptake, less storage. The authors warn that such swings may dent cell energy in hard training blocks.
