In exercise science, the term “VO2 max” signifies the maximum rate at which an individual can consume oxygen during intense exercise. It serves as a key indicator of aerobic endurance and cardiovascular fitness. A higher VO2 max correlates with better performance in endurance sports, as it reflects the efficiency of the body’s oxygen transport and utilization systems. Training programs often aim to improve VO2 max, enabling athletes to sustain higher intensities for longer durations.
