Supports chemoreflex role in anaerobic hyperpnea; leaves open clinical oxygen use during heavy work.
Does oxygen breathing reduce lung ventilation and blood lactate concentration in subjects performing heavy muscular work?
Oxygen breathing during heavy work decreases ventilation and blood lactates by depressing chemoreceptor activity, suggesting an unidentified substance drives the reflex increase in ventilation during anaerobic work.
Asmussen et al. (1946) studied this question.
