From the moment it appeared online last month, an editorial in the journal Heart became a Rorschach test for opinions about runners.
Do you roll your eyes when they start talking about their races and times? Do you snigger when you see bumper stickers that simply say “26.2,” the number of miles in a marathon, or “13.1,” the half-marathon distance? Do you lose patience with family members who have to go for a run — even if it means waking up at 4 a.m. before leaving on a vacation?
Then perhaps the editorial will appeal to you. It was titled “Run for your life… at a comfortable speed and not too far.” The authors, Dr. James H. O’Keefe Jr. of Saint Luke’s Mid America Heart Institute Hospital in Kansas City, Mo., and Dr. Carl J. Lavie of the Ochsner Health System in New Orleans, wrote that those who run slowly and keep their mileage down gain health benefits. But those who run for more than about 40 minutes a day and those who run faster than eight minutes a mile actually increase their risk of death.
Too much or too intense running, the two cardiologists said, “appears to cause excessive ‘wear and tear’ on the heart.”
The editorial got extensive news attention, often tinged with schadenfreude. “What do you get if you finish a marathon? A finisher’s medal and a risk of death! ” said MSN-Now. The Wall Street Journal’s article was headlined “One Running Shoe in the Grave.”
On the other side, of course, were aggrieved runners. Runner’s World instantly published a rejoinder titled “The Too-Much-Running Myth Rises Again.” The Heart editorial, it said, was “twisting the data.”
Meanwhile, some runners panicked. “I got 650 e-mails in four hours,” said Dr. Aaron Baggish, associate director of the cardiovascular performance program at the Massachusetts General Hospital. (Dr. Baggish cycles, he runs — more than 30 marathons so far — and he competes in triathlons. “I certainly exceed any dose of exercise that has been said to be bad for you,” he noted.)
By now the evidence has been thoroughly dissected. Suffice it to say that leading exercise researchers agree with Runner’s World and have stacks of journal articles to bolster their arguments.
Dr. Benjamin Levine, a competitive tennis player and director of the Institute for Exercise and Environmental Medicine at Texas Health Resources and the University of Texas Southwestern Medical School, said: “You can always find one or two papers and studies that, if you spin the right way, can seem to reflect your argument.”
But, he added, while health benefits rise most sharply as people go from sedentary to moderately active, there is no good evidence that they decline, or even level off, for distance runners. “Our data and other data are quite convincing,” Dr. Levine said.
Dr. O’Keefe is not swayed. In an as yet unpublished editorial, he recommends running just two or three miles at a relaxed pace a few times a week, interspersed with days of swimming, a couple of sessions of weight lifting and some yoga. In an interview, he said that was his own exercise regimen.
The real question, though, is why does running arouse such passions? You don’t hear gleeful chortling about the health hazards to master swimmers or cross-country skiers or cyclists who do 100-mile “century” rides.
Dr. Paul Thompson, a cardiologist and exercise researcher at Hartford Hospital who is also an endurance athlete, cites two factors. First, he said, among runners “a lot of people use their athleticism in an attempt to show they are a superior human being.”
Paula Broadwell said she ran in the mountains of Afghanistan with Gen. David H. Petraeus, maintaining a pace of six or seven minutes a mile while interviewing him. The Wall Street Journal published her available race times, in an article that gushed over her speed.
But it was clear to runners that she could not possibly have run that fast, even at sea level. Her best time in a race was 7:21 minutes a mile, and most people race faster than they normally run. Even that pace barely put her in the 70th percentile for her age.
When runners use their prowess, real or exaggerated, to suggest superiority, they generate resentment, Dr. Thompson noted. As a result, he said, “people love to find studies that support the bias that too much exercise is bad.”
Why is this not an issue in other sports? Runners, Dr. Thompson and others say, are just so much more plentiful than other athletes; if you find yourself resenting an athlete who fancies himself superior, odds are that athlete will be a runner. And running appears so easy — anyone can run, it seems. Anyone can finish a marathon, even Oprah Winfrey did it. So those who do not run can feel a little defensive.
Added to that is all the running talk by devotees who may not realize how annoying and boring their monologues can be. Dr. Baggish said his patients often bring in huge folders full of decades worth of data — heart rates on various runs, finishing times in races.
“They can talk about it until the cows come home,” he said.
So it might behoove runners to keep their running talk and braggadocio to their running friends. There may be something more than health concerns behind those cracks from friends and family about failing knees and backs and heart attacks among runners.
“When I see runners in my office, I always encourage them to bring their spouses,” Dr. Baggish said. Often a wife, for example, will start to complain: her husband “can’t enjoy Christmas Day with the family because he has to run.” A husband might say he just can’t understand why his wife has to be out there all the time running.
“That sort of inconvenience translates into concerns about health,” Dr. Baggish said.
