Oxygenation of respiratory and locomotor muscles during maximal exercise in two marathon runners

A high work of breathing (WOB) associated with pulmonary hyperventilation during physical exercise, may limit sports performance in long-distance runners (e.g. marathon). The assessment of changes in WOB during maximal oxygen consumption test (V̇O2-máx.) allows knowing the intensity of exercise at w...
