Maximal oxygen consumption (VO2max) is the gold standard to measure one’s cardiopulmonary fitness. The VO2max represents the maximal flow of oxygen through the lungs into blood via., simple diffusion, which in turn gets pumped by the heart into the muscles during the maximal graded exercise test (GXT). It was long thought that lung function may not be a limiting factor for one’s maximal performance during … Continue reading Heart-Lung-Muscle axis | Role of the lungs in maximal oxygen consumption
