Contribution of Respiratory Muscle Oxygen Consumption to Breathing Limitation and Cyspnea

During exercise, the sustainable activity of large muscle groups is limited by oxygen delivery. The purpose of this study was to see whether the oxygen consumption of the respiratory muscles reaches a similar critical value under maximal resistive loading and hyperventilation. A secondary objective was to see whether dyspnea (estimated discomfort experienced with breathing using the Borg 0‐10 scale) and the oxygen consumption of the respiratory …
