VO2 Max
VO2 max, or maximal oxygen uptake, is the maximum amount of oxygen an individual can utilize during intense or maximal exercise. It is considered the best indicator of cardiovascular fitness and aerobic endurance. Higher VO2 max values are associated with increased longevity and reduced risks of heart disease. This metric is particularly useful in assessing the efficiency of an individual‘s heart, lungs, and circulatory system in delivering oxygen to working muscles during physical activity. Regular exercise can improve VO2 max, suggesting it is a modifiable factor through lifestyle changes.
