Effects of hypoxia on the onset of muscle deoxygenation and the lactate threshold.
Six subjects performed two trials of incremental cycling to exhaustion under normoxic and hypoxic conditions. The lactate threshold and onset of muscle deoxygenation were highly correlated under both conditions, and during the hypoxic condition both variables shifted leftward.
