The link between VO2 max (Maximal Oxygen Uptake) and longevity

VO2 max, also known as maximal oxygen uptake, measures the maximum amount of oxygen an individual can consume during exercise. A higher VO2 max reading correlates with the ability to perform high-intensity physical activity for longer. VO2 max can be improved through regular exercise, particularly cardiovascular and high-intensity interval training.

There is strong evidence to suggest a link between VO2 max and longevity. A study has shown that training at any intensity above ~60% of VO2max is likely to improve maximal oxygen uptake in healthy adults[1]

While the exact mechanisms behind the link between VO2 max and longevity are not fully understood, it is believed that higher aerobic fitness levels may help reduce inflammation, improve cardiovascular function, and promote overall health and wellbeing, which may lead to to a longer and healthier life.
