A Response to Media Scrutiny on “Running Too Much”
http://runnersconnect.net/running-injury-prevention/is-running-
"Despite the attention-grabbing headlines you’ll read in the New York Times
and other such magazines and papers, running higher mileage and training
for marathons and half marathons does not seem to negatively impact your
health and well-being."
Last week, we took a look at the types of running injuries that
ultramarathoners suffer. Though they largely get the same injuries as “
regular” runners, there are a few interesting differences that might have
something to do with the prodigious volumes of running that ultramarathoners
do.
While injuries are obviously a concern for any runner, a bigger question
about high mileage, long training runs, and races is how running higher
mileage affects your overall health and well-being.
There’s been a lot of back and forth recently about this issue. It’s well
-established that a moderate amount of exercise keeps you healthy and helps
you live longer. But the effects of what some people call “extreme”
exercise are uncertain.
Some research has suggested that a major loads on your body, like running a
marathon, can produce transient stresses on your cardiovascular system,
which may translate into more permanent damage.
On the other hand, other research suggests high-volume exercise incurs no
lasting harm.
In this article, we’ll further examine one major study that attempts to
answer the question on whether running high mileage is actually healthy for
you.
How high mileage impacts a runners’ health
The Ultrarunners Longitudinal Tracking Study, or ULTRA for short, was
designed in part to help answer the question: “Is running high mileage bad
for you?”
To do this, the ULTRA study will follow 1,212 ultramarathoners for a very
long time, probably until the end of their lives, to see how their exercise
habits affect their health.
The study was undertaken only three years ago, so the biggest question marks
—the effects of high-volume running on cardiovascular health and lifespan—
remain unanswered. But, there is still a lot to be learned from the
preliminary survey of the health history of the ultra runners in the study.
The average participant in the study was 36 years old, confirming that most
ultramarathoners (and especially the faster ones) tend to be older than your
typical 5k or 10k hotshot.
Ultramarathoners are also a pretty experienced bunch, as the majority of the
subjects in the study had been running for at least seven years before they
competed in their first ultramarathon.
Overall, ultra runners as a whole are a pretty healthy bunch.
The study’s participants only missed 2.2 days of work or school in the last
year because of injury or illness, compared to 3.7 days among the general
population.
And the ultramarathoners were confined to bed only one day out of the past
year because of an injury or sickness versus 4.7 days among the general
population.
The ultra-runners had a low, although not nonexistent, incidence of high
blood pressure and irregular heartbeats, with about 7.5 percent of the
runners reporting one of those problems.
Less than 1 percent had been diagnosed with heart disease or had a past
stroke, and few had experienced cancer, with basal cell skin carcinoma being
the most common malignancy, occurring in 1.6 percent of the runners. Those
percentages are generally lower than among age-matched American adults,
especially considering that a majority of the ultra-runners were aged 40 or
older.
Even when you control for the fact that ultramarathoners tend to be better-
educated and more likely to hold office jobs, these trends still hold.
Even though 77% of the runners in this study suffered a running injury
during the past year, they visited the doctor less often than non-runners.
And among the doctor’s visits that the runners did incur, nearly two-thirds
were only because of a running-related injury.
This is not to imply that the ultramarathoners in this study were perfectly
healthy.
How healthy are ultramarathoners?
As you’d expect with any decently large cross-section of the population, a
handful of the subjects in the ULTRA study were diabetic, asthmatic, HIV
positive, cancer patients, living with cardiovascular disease, and so on.
A total of 28% of the runners took medication for some type of medical
condition.
The incidence of virtually all medical conditions was lower in the
ultramarathoners than in the population as a whole.
The only two exceptions to this were asthma and allergies or hay fever.
Around 13% of the ultramarathoners had exercise-induced asthma, and 25% had
allergies or hay fever.
Among the general population, these numbers are 8% and 7%, respectively.
Both asthma and allergies are known to be more prevalent in endurance
athletes, probably because of their increased exposure to allergens and
pollutants in the air. It shouldn’t be too surprising that
ultramarathoners, who inhale large volumes of whatever is in the air where
they run and compete, have a higher rate of these two conditions.
Conclusion
The running habits of the subjects in the ULTRA study appear to confer some
remarkable health benefits, at least in the short term.
The group as a whole averaged 2,080 miles in the past calendar year—40
miles per week—which is pretty impressive for a group of over 1,200 runners.
These ultrarunners missed fewer days of work, needed less medical care, and
had a lower incidence of pretty much every serious medical condition
compared to the general population. Notably, however, allergies, hay fever,
and asthma are bigger concerns for the ultramarathoning community.
We’ll have to wait a while to see whether this trend of good health
continues for the runners in the ULTRA study, but what does this suggest for
you, right now?
Despite the attention-grabbing headlines you’ll read in the New York Times
and other such magazines and papers, running higher mileage and training for
marathons and half marathons does not seem to negatively impact your health
and well-being.
Of course, we’ll need to continue to follow the runners in this study, but
right now the data shows running higher mileage is good for you! | m******r

发帖数: 220 | 3 The information here is useless. The study is obviously badly designed.
People who are able to run ultramarathons must be healthier than general
population. i can't imagine most of patients with cardiovascular diseases or
cancers are willing to or able to run ultra. The problem is those ultra
people may be even more healthy if they hadn't run that much.
also, the average mileage is 40 mpw. I don't call this extremely long
mileage. Many people in this board run more than that. I want to see the
effect of 100 mpw on human body. | R*****s

这显然是你自己的假设，实际上不少跑步的人都不是运动员，甚至是因为身体
本身有问题才开始跑的. 文中有说测试的人群都是普通坐office的，非运动员.
2.the average mileage is 40 mpw. I don't call this extremely long mileage.
你不觉得多，对于每周只能跑20mpw的，就是high mileage了.上次不还有个文章鼓吹
每周超过15迈就算多了么？
3.I want to see the effect of 100 mpw on human body.
说实话，等你真跑到100MPW了，才需要关心这问题. 任何人到了一定的量，自然身体
就会累，或者受伤了，多大的量算大，都是因人而异.

我记得potato自己也贴过一个paper, 耐力运动员普遍比普通人活得长,
但你非说这是因为基因活得长的都去搞耐力运动了，那我也没办法...

You report yourself how healthy you are by answering questions, not the most
reliable way for doing such studies.
Don't hate me. I know I should not take the survey but I did anyway just to
check how they reach their conclusions. Basically you will need to answer
these questions for a lot of deseases...
Have you been told you had this medical condition?
If present, what was the year of onset?
If present, are you currently taking medication for the condition?
Like other self_reported surveys it is not that convincing to me.

如果把跑步换成抽烟，你怎么想？
为啥担心抽烟太多影响健康的的都是实际抽得不多的，真正抽100包烟50MPW（2000迈/

我不是替别人担心。现在跑不到100mpw，不意味着以后不会跑到。我从来没有劝过其他
人不要跑太多，知道大剂量跑步的好处和坏处是我个人兴趣。

发帖数: 41236 | 14 我的逻辑非常对，我自己不抽烟，所以别人抽烟会不会死，我一点也不关心.
好比你如果自己没艾滋，整天去关心艾滋病还有没有救，我只能说你闲的蛋疼...
另外你自己也承认跑步群体比普通人健康，但你又非要说这跟跑步没关系，
自己跑得不多，但非要研究清楚跑太多是不是有害，我也只能说你闲得蛋疼....
身体变好变坏，你自己没感觉？闲跑太多了，少跑点不就完了，又没人拿枪指着你跑？
