peak oxygen uptake

Peak oxygen uptake, or VO2 max, measures the maximum amount of oxygen your body can use during intense exercise. It reflects your cardiovascular and respiratory efficiency, indicating how well your heart, lungs, and muscles work together to supply and utilize oxygen. A higher VO2 max suggests better aerobic fitness and endurance, allowing you to perform sustained physical activity more effectively. It’s commonly used by athletes to assess fitness levels and by medical professionals to evaluate overall heart and lung health. Essentially, it’s a key indicator of your body's capacity to deliver and use oxygen during demanding exercise.
