The lung at maximal exercise: insights from comparative physiology.
Horses are bred selectively for aerobic performance and have extraordinarily high maximal oxygen consumption, approximately double the mass-specific value for human athletes. Pulmonary limitations to exercise performance are well described in these animals, including exercise-induced arterial hypoxemia and exercise-induced pulmonary hemorrhage. In human athletes, pulmonary limitations are recognized increasingly as affecting athletic performance. Potential pulmonary limitations during maximal exercise are compared in human and equine athletes.
