Hypoxie and Hyperoxia
In contrast tothe various acute and chronic responses to hypoxia (i.e., lowering of the partial pressure of oxygen in the air, for example by various forms of altitude training), far less is known about the responses to acute, and especially to chronic exercise in hyperoxia (i.e. elevation of the fr...
