Which definition BEST describes VO2max?
Why each option is right or wrong
Pick an answer. Then tap any option to read its explanation, the wrong ones included.
A — Correct. VO2max is the maximal rate at which the body takes up and uses oxygen, usually given in mL/kg/min; it is the standard marker of cardiorespiratory fitness.
B — Not this one. Maximal heart rate is only one part of oxygen delivery. Two people with the same HRmax can have very different VO2max values.
C — Not this one. The largest volume of air the lungs hold is total lung capacity, a lung volume, not an oxygen-use rate.
D — Not this one. Arterial oxygen content at rest is a blood measure. VO2max is measured during maximal exercise.
