Higher exercise capacity (measured in METs) is inversely and independently associated with all-cause mortality in older men (aged 65-92), with significant survival benefits achieved at capacities above 5 METs.

For older men, focusing on improving physical fitness (measured as METs) is one of the most powerful ways to extend life. You do not need to be an elite athlete; achieving a moderate fitness level (above 5 METs, roughly equivalent to brisk walking or light jogging) provides significant survival benefits. If you are currently unfit, improving your fitness through regular activity can lower your mortality risk by approximately 35% compared to staying unfit.

GoodSupportsHIGH confidence
Exercise capacity is an independent predictor of all-cause mortality in older men. The relationship is inverse and graded, with most survival benefits achieved in those with an exercise capacity >5 METs.

Why this rating

Large sample size (n=5314), long follow-up (median 8.1 years), and robust statistical adjustment for confounders, though it is an observational cohort study.
