The decision to train at altitude and compete at sea level was flawed and dispenses with previous sports performance research. Hypoxia inducible factor (from altitude training) increases iron absorption from the gut to theoretically provide for higher levels of red blood cells but offers no potential advantage when competing at sea level. The same hypoxia inducible factor does, however, impair Krebs cycle oxidative efficiency by upregulating the pyruvate dehydrogenase kinase inhibition on pyruvate dehydrogenase.
That's what I've been saying all along!
Thank you, I understand completely now. (Er, were all those real words?)
