The effects of breathing supplemental oxygen during altitude training on cycling performance

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...

Zusammenfassung: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 relative workload while breathing hyperoxic gas (P 1O 2 = 156 Tord. HYPER subjects were able to train at a higher percentage of their altitude lactate inflection point than were NORM subjects (HYPER = 126±2%, NORM = 109±3% p
