There is nothing better than exercise but more exercise.
Regular physical activity (PA) and high cardiorespiratory fitness (CRF: aerobic capacity, VO2 max) reduce all-cause mortality even after adjusting for relevant confounders.1 2 Large-scale studies indicate an almost linear relationship between increasing CRF and longevity, with no signs of an upper limit.3 It remains less clear which PA volumes are optimal for a long life. Public health guidelines recommend a minimum of 150–300 min moderate intensity aerobic PA or 75–150 min vigorous intensity aerobic PA per week to induce general health benefits.4
How much bang can you get for a PA buck?
Dr Hannah Arem and colleagues, using pooled data from six studies in the USA and Europe (including 661 137 adults), showed that meeting PA guidelines was associated with a large longevity benefit.5 And there were even further improvements until the benefit for longevity reached a threshold at a level 3–5 times higher (450–750 min/week) than the minimum recommendations, without adverse effects in those performing PA at ≥10 times that minimum. The maximum all-cause mortality reduction was almost 40% without relevant differences between …
