Running a little can also reduce the risk of death

A meta-regression analysis combining results from three cohort studies showed no significant dose–response trends.

Running is associated with reduced mortality risk, even in small doses, according to a meta-analysis in the British Journal of Sports Medicine.

The analysis included data from six prospective cohorts comprising over 230,000 adults, in whom associations between running and mortality were examined. All running data were self-reported.

This systematic review synthesized the results of 14 studies from six prospective cohorts with a pooled sample of more than 230 000 participants. Overall, 11% of the study participants died within 5 to 35 years’ follow-up. After multivariable adjustment, runners had a 27% lower mortality risk than nonrunners. Both women and men saw significant mortality reductions with running. In subanalyses, risk reductions were seen for cardiovascular and cancer mortality.

Even small amounts of running — for example, running once a week or for less than 50 minutes a week — were associated with reductions in all-cause mortality. The benefits did not appear to increase with more running.

The researchers say the findings “may be encouraging for people who struggle to find the time to exercise.”
