How long will a person live: scientists find an unexpected indicator

Norwegian researchers have identified a link between maximal oxygen consumption (VO2 max) and the risk of premature death. An analysis of data from approximately 55,000 people showed that low cardiorespiratory fitness is associated with a higher risk, while high fitness is linked to greater longevity. Scientists note that VO2 max can be improved through physical activity, including high-intensity interval training, even after age 50.

Norwegian researchers analyzed data from approximately 55,000 people and found a link between maximal oxygen consumption (VO2 max) and the risk of premature death. Participants with poorer fitness levels had a higher risk, while higher cardiorespiratory fitness was associated with greater longevity. However, VO2 max cannot be considered an accurate way to determine how many years a specific person has left—many factors influence lifespan, including genetics, chronic diseases, lifestyle, and environment. The good news is that cardiorespiratory fitness can be improved. Researchers recommend regular physical activity, noting that positive changes are possible even for people who start training after age 50. Special attention is given to high-intensity interval training, where short periods of intense effort alternate with recovery.
