From Your Health Journal…..”The Wall Street Journal has some fantastic health articles, please visit their site (link provided below) to read some great stories, including the one being reviewed here. This article is actually quite alarming for many as a fast-emerging body of scientific evidence points to a conclusion that’s unsettling, to say the least, for a lot of older athletes: Running can take a toll on the heart that essentially eliminates the benefits of exercise. In a study involving 52,600 people followed for three decades, the runners in the group had a 19% lower death rate than nonrunners, according to the Heart editorial. But among the running cohort, those who ran a lot—more than 20 to 25 miles a week—lost that mortality advantage. So, it appears the training for endurance may not be as healthy as once thought, rather short bursts of aerobic exercise may be more beneficial to many.

From the article…..

In a five-kilometer race Thanksgiving morning, Ralph Foiles finished first in his age group, earning the 56-year-old Kansan a winner’s medal.

Or was it a booby prize?

A fast-emerging body of scientific evidence points to a conclusion that’s unsettling, to say the least, for a lot of older athletes: Running can take a toll on the heart that essentially eliminates the benefits of exercise.

“Running too fast, too far and for too many years may speed one’s progress toward the finish line of life,” concludes an editorial to be published next month in the British journal Heart.

Until recently, the cardiac risk of exercise was measured almost exclusively by the incidence of deaths during races. For marathoners, that rate was one in 100,000—a number that didn’t exactly strike fear. Moreover, data showed that runners generally enjoyed enormous longevity benefits over nonrunners.

What the new research suggests is that the benefits of running may come to a hard stop later in life. In a study involving 52,600 people followed for three decades, the runners in the group had a 19% lower death rate than nonrunners, according to the Heart editorial. But among the running cohort, those who ran a lot—more than 20 to 25 miles a week—lost that mortality advantage.

Meanwhile, according to the Heart editorial, another large study found no mortality benefit for those who ran faster than 8 miles per hour, while those who ran slower reaped significant mortality benefits.

Those two studies—presented at recent medical conferences—follow the publication in recent months and years of several other articles finding cardiac abnormalities in extreme athletes, including coronary artery calcification of a degree typically found in the utterly sedentary.

Meghan Newcomer is a 32-year-old professional triathlete who has passed out during several races in recent years.

Opinion is nearly unanimous among cardiologists that endurance athletics significantly increases the risk of atrial fibrillation, an arrhythmia that is estimated to be the cause of one third of all strokes. “Chronic extreme exercise appears to cause excessive ‘wear-and-tear’ on the heart,” the editorial says.
