This suggests that strenuous exercise may pose health risks over the long term, particularly for the cardiovascular system, the researchers said.

“The U-shaped association between jogging and mortality suggests there may be an upper limit for exercise dosing that is optimal for health benefits,” Dr Peter Schnohr, lead researcher from Frederiksberg Hospital in Copenhagen, said in a statement.

“If your goal is to decrease risk of death and improve life expectancy, jogging a few times a week at a moderate pace is a good strategy.

“Anything more is not just unnecessary, it may be harmful.”

In 2001, the researchers began analysing data from 1098 healthy joggers and 3950 healthy non-joggers from the
