Study Question: Does physical activity affect life expectancy in men and women with and without cardiovascular disease (CVD)?

Results: Moderate and high physical activity levels led to 1.3 and 3.7 years more in total life expectancy and 1.1 and 3.2 more years lived without CVD, respectively, for men aged 50 years or older compared with those who maintained a low physical activity level. For women, the differences were 1.5 and 3.5 years in total life expectancy and 1.3 and 3.3 more years lived free of CVD, respectively.

Conclusions: Avoiding a sedentary lifestyle during adulthood not only prevents CVD independently of other risk factors, but also substantially expands the total life expectancy and the CVD-free life expectancy for men and women. This effect is already seen at moderate levels of physical activity, and the gains in CVD-free life expectancy are twice as large at higher activity levels.

Another study showing moderate or high intensity exercise (but not low levels) increases lifespan and healthy years of life as well. GLE
