Why the study?
Does breathing 12% O2 compared to room air affect the relationship between lactate efflux and intracellular PO2 during incremental exercise in trained subjects?

Lactate efflux during incremental exercise may not reflect intracellular hypoxia; hypothesis-generating for O2 consumption-linked mechanisms in trained subjects.
Does breathing 12% O2 compared to room air affect the relationship between lactate efflux and intracellular PO2 during incremental exercise in trained subjects?
Lactate efflux during progressive exercise is unrelated to muscle cytoplasmic PO2, suggesting that lactate formation is not solely due to intracellular hypoxia.
Richardson et al. (1998) studied this question.
