HYPOXIC, HYPOXIA
In the second session, after 30 min being under hypoxia at rest, participants underwent the maximal incremental test (Astrand Test for Men) on a cycle ergometer (Cyclus 2, RBM Elektronik-Automation GmbH, Leipzig, Germany) to measure PPO under the hypoxic condition. The test was started with 100 watts and a cadence of 60 rpm for three minutes and 50 watts increments every three minutes
