Increasing one's VO2 max is a key factor in reducing all-cause mortality and significantly extending lifespan.

VO2 max, which measures the body's ability to use oxygen during exertion, is widely recognized by the scientific community as a robust indicator of cardiorespiratory health. Major meta-analyses, notably those published in the Journal of the American College of Cardiology, confirm an inverse dose-response relationship between aerobic fitness and mortality. The claim regarding risk reduction is supported by large-scale observational studies showing that moving from a low fitness level to a high one is correlated with a dramatic decrease in the risks of premature death. It is important to note, however, that while the correlation is very strong, VO2 max is not the only determinant of longevity; genetics and other lifestyle habits also play a role. The 'four times higher risk' aspect for the least trained is a statistical interpretation consistent with long-term follow-up data. This observation is therefore firmly anchored in current scientific literature.
