It has been suggested that the act of taking a stride produces substantial respiratory volume displacement and that this assists the respiratory muscles during locomotion. We measured the flow at the mouth associated with stride in walking and running humans and found it to be 1-2% of respiratory tidal volume, which is too small to make an appreciable contribution to pulmonary ventilation.
