Evidence of O2 supply-dependent VO2max in the exercise-trained human quadriceps

Maximal O2 delivery and O2 uptake (VO2) per 100 g of active muscle mass are far greater during knee extensor (KE) than during cycle exercise. Richardson et al tested the hypothesis that muscle VO2max during human KE exercise would be reduced in hypoxia as a result of a fall in O2 delivery and would...

Description
Summary:	Maximal O2 delivery and O2 uptake (VO2) per 100 g of active muscle mass are far greater during knee extensor (KE) than during cycle exercise. Richardson et al tested the hypothesis that muscle VO2max during human KE exercise would be reduced in hypoxia as a result of a fall in O2 delivery and would be elevated in hyperoxia as the result of an increased O2 supply.
