What does the term "vo2 max" measure?

The term "vo2 max" refers to the maximum amount of oxygen that the body can utilize during intense exercise. It serves as a key indicator of an individual's aerobic capacity and cardiovascular fitness. Higher vo2 max values typically indicate a more efficient cardiovascular and respiratory system, allowing more oxygen to be delivered to and used by the muscles during physical activity. This measurement is crucial for understanding an athlete's performance potential and overall fitness level, as it reflects the body's ability to sustain prolonged exercise. While vo2 max can influence endurance levels, it specifically quantifies the oxygen consumption limit rather than just generalized endurance or muscle strength alone.
