Question

Quizplus · Accepted Answer

Maximal oxygen uptake, also known as VO2max, is a valid measurement of cardiovascular fitness and represents the maximum amount of oxygen the body can consume during exercise. It is also a physiological ceiling for the ability of the oxygen transport system to deliver oxygen to the working muscles. Therefore, both A and B are correct. Option C is incorrect as VO2max is actually measured at the point where lactate threshold is reached.
