The term for the maximum amount of oxygen the body can utilize during intense exercise is VO2 max. This measure reflects an individual’s aerobic capacity and overall cardiovascular fitness. It indicates how efficiently the body can convert oxygen into energy during high-intensity physical activity. Higher VO2 max values are generally associated with greater endurance and athletic performance. Factors affecting VO2 max include genetics, age, training level, and altitude. Improving VO2 max through structured aerobic training can enhance athletic performance and overall health.
