Study: Running can counter premature death

Minimum of five minutes a day can add three years

People who jogged or ran for as little as five minutes a day reduced their risk of premature death by nearly one-third and extended their lives by about three years, according to a new study.

Researchers examined the exercise habits of more than 55,000 adults in the Dallas area who were monitored for six to 22 years. About 24 percent of the adults described themselves as runners.

Compared to those who didn’t run, those who did were 30 percent less likely to die of any cause during the course of the study. They were also 45 percent less likely to die as a result of cardiovascular disease, researchers reported Monday in the Journal of the American College of Cardiology. (The figures were adjusted to take into account people’s smoking and drinking habits, how old they were when they enrolled in the study, their family’s health history and their other exercise habits.)

Put another way, non-runners were 24 percent more likely than runners to die during the study period. In fact, the mortality risk associated with not running was greater than the mortality risk associated with being overweight or obese (16 percent), having a family history of cardiovascular disease (20 percent), or having high cholesterol (6 percent).

The researchers divided the roughly 13,000 runners into five groups based on how many minutes they ran per week. Those in the lowest group ran up to 50 minutes over a seven-day period, and those in the highest group ran for more than 175 minutes over the course of a week.

But the benefits of running were pretty much the same for all runners, according to the study.

“Running even at lower doses or slower speeds was associated with significant mortality benefits,” the researchers found.

They also measured running in other ways – by total weekly distance, frequency, speed and the “total amount of running” (which was calculated by multiplying duration and speed). In all categories, even the runners in the lowest groups were less likely to die during the study than the non-runners.

To reduce the risk of premature death, all it took was 30 to 59 minutes of running per week, the researchers calculated.
