Maximum aerobic capacity

Maximum aerobic capacity, often called VO₂ max, is the highest amount of oxygen your body can use during intense exercise. It reflects your cardiovascular fitness and how efficiently your heart, lungs, and muscles work together. A higher VO₂ max means you can perform endurance activities, like running or cycling, for longer and at higher intensities. It’s influenced by genetics, training, age, and health. Typically measured through specialized exercise tests, VO₂ max provides insight into overall aerobic health and athletic conditioning.
