In a major review of the health benefits of running, a team of scientists from the Iowa State University have concluded that regular runners live longer. The average gain in life expectancy was three years. This doesn’t take into account the frequency of running, except that it has to be more than once a week.
But it’s not the running that’s important; it’s the type of exercise. Running just happens to be the most commonly performed type of recreational intense exercise. Even at a slow jog, running requires a full set of working muscles and joints, plus a degree of determination (not to mention coordination) and, importantly, some pre-existing fitness. So runners are generally fit people in good health. This also applies to all people competing in most sports or doing intense exercise sessions.
It’s aerobic exercise, irrespective of the type, that is the elixir of a longer life.
