Here’s another opportunity to put 2 and 2 together and get: Ashtanga ought to be really good for you.
A new study, detailed here by the New York Times, has found that even a little bit — like five minutes a day — of vigorous exercise can have great health benefits:
Running for as little as five minutes a day could significantly lower a person’s risk of dying prematurely, according to a large-scale new study of exercise and mortality. The findings suggest that the benefits of even small amounts of vigorous exercise may be much greater than experts had assumed.
For decades, researchers there have been collecting information about the health of tens of thousands of men and women visiting the clinic for a check-up. These adults, after completing extensive medical and fitness examinations, have filled out questionnaires about their exercise habits, including whether, how often and how speedily they ran.
From this database, the researchers chose the records of 55,137 healthy men and women ages 18 to 100 who had visited the clinic at least 15 years before the start of the study. Of this group, 24 percent identified themselves as runners, although their typical mileage and pace varied widely.
The researchers then checked death records for these adults. In the intervening 15 or so years, almost 3,500 had died, many from heart disease.
But the runners were much less susceptible than the nonrunners. The runners’ risk of dying from any cause was 30 percent lower than that for the nonrunners, and their risk of dying from heart disease was 45 percent lower than for nonrunners, even when the researchers adjusted for being overweight or for smoking (although not many of the runners smoked). And even overweight smokers who ran were less likely to die prematurely than people who did not run, whatever their weight or smoking habits.
As a group, runners gained about three extra years of life compared with those adults who never ran.
Remarkably, these benefits were about the same no matter how much or little people ran. Those who hit the paths for 150 minutes or more a week, or who were particularly speedy, clipping off six-minute miles or better, lived longer than those who didn’t run. But they didn’t live significantly longer those who ran the least, including people running as little as five or 10 minutes a day at a leisurely pace of 10 minutes a mile or slower.
For those who want to go right to the source, here’s a link to the study.
And then here’s why we can make a leap to Ashtanga:
The study did not directly examine how and why running affected the risk of premature death, he said, or whether running was the only exercise that provided such benefits. The researchers did find that in general, runners had less risk of dying than people who engaged in more moderate activities such as walking.
But “there’s not necessarily something magical about running, per se,” Dr. Church said. Instead, it’s likely that exercise intensity is the key to improving longevity, he said, adding, “Running just happens to be the most convenient way for most people to exercise intensely.”
The question, I suppose, is whether Ashtanga would count as vigorous exercise — unless done really leisurely, I can’t imagine it as moderate exercise. If you think it isn’t quite strenuous enough, there seems to be a few things to consider:
- The focus ought to be on the vinyasa part of the practice (and maybe some of the tougher arm balances). Although it has been removed, for instance, maybe a short burst of full vinyasa might make sense. (That is, of course, with the intent of meeting these vigorous guidelines, which may not be your aim with your practice.)
- I know in some quarters a Led Primary is pushing down toward an hour. While it has never been my preference, perhaps there’s something to it — again, for purposes related to this study.
- Perhaps some intrepid rebel Ashtanga teacher wants to add a vigorous little section to the practice, maybe incorporate it into an improv class a few times a week. What about adding full vinyasa around Navasana?
Or, I suppose, you simply have to throw in five minutes of some other vigorous exercise per day. That’s not too much to ask, right?
What we really need is a study that looks at the combination of some vigorous exercise with a yoga practice.
