Supports peripheral oxygen extraction gains from training in chronic lung disease; hypothesis-generating and should not yet change practice.
Does physical training improve symptom-limited oxygen consumption and hemodynamics in male patients with chronic lung disease?
Physical training in patients with chronic lung disease improves oxygen consumption primarily by increasing the ability of muscles to extract oxygen from circulating blood, without changing maximal cardiac output.
Degré et al. (1974) studied this question.
