The Oxygen Limit
Alex Hutchinson discusses the various factors that can cause a plateau in oxygen intake and highlights the controversies surrounding lung training and oxygen diffusion. He explains how highly trained endurance athletes can be limited by their ability to get enough oxygen and how exercise-induced arterial hypoxemia can affect even elite athletes. With every stage of the process susceptible to limitations, the quest for understanding the ultimate oxygen limit continues.In this clip
