Maximal oxygen uptake, commonly referred to as VO2 max, is the primary measure used to assess cardiovascular fitness. This metric indicates the maximum amount of oxygen that an individual can utilize during intense exercise. It reflects how well the heart, lungs, and muscles work together to deliver and use oxygen, making it a key indicator of aerobic endurance.

When performing physical activities, the body requires a continuous supply of oxygen to meet the energy demands. A higher VO2 max value typically correlates with better endurance, allowing one to perform activities such as running or cycling for longer periods without excessive fatigue. Training can improve this metric, demonstrating enhancements in cardiovascular conditioning.

While resting heart rate may give insights into an individual's cardiovascular health and efficiency, it does not directly measure the capacity for aerobic activity like VO2 max does. Body fat percentage and muscle strength, on the other hand, are unrelated to cardiovascular fitness; they focus on body composition and muscular capabilities rather than the efficiency of the cardiovascular system. Thus, VO2 max serves as the most comprehensive measure of cardiovascular fitness.
