The effects of breathing supplemental oxygen during altitude training on cycling performance
To compare the training effects of doing high intensity intervals at 1840 m in a normoxic vs. hyperoxic environment, eight cyclists (NORM) performed intervals on ergometers 3d/wk while breathing normoxic gas (P 1O 2 = 128 Torr), and seven subjects (HYPER) performed identical intervals at the same re...
