VO2 max is a measure of which aspect of fitness?

• A. The maximum amount of oxygen that can be transported and used by the body in a specified period of intense/maximal exercise
• B. A range of movement at a joint
• C. A measure of cardiovascular fitness
• D. The time between stimulus and movement

Answer: (C)

VO2 max represents the body's maximum rate of oxygen uptake during intense exercise. It shows how efficiently the heart and lungs can deliver oxygen to working muscles and how effectively those muscles can use that oxygen to produce energy. Because it reflects the capacity of the cardiorespiratory system to sustain aerobic activity, it’s best described as a measure of cardiovascular fitness. It isn’t about how far a joint can move or how quickly you react to a stimulus, which is why the other traits don’t fit as well.
