Maximal Oxygen Uptake

Knowledge of how oxygen is transported from the ambient air to the tissue cells of the body is essential to an understanding of the mechanisms by which the body adapts to the oxygen demands of muscular exercise. The requirement of oxygen by the various tissue cells of the body is met by the combined cardiovascular and pulmonary systems, which function as a unit termed the oxygen transport system of the body. If a person is subjected to progressively increasing work loads, there is a linear relation between work load and oxygen uptake until the maximal oxygen uptake is reached. Heavier.
