walk this way? run?
Jared Sperli stashed this in life
Runners have better appetite suppression and tend to burn more calories.
But walkers have tremendous health benefits:
The runners also proved after exercise to have significantly higher blood levels of a hormone called peptide YY, which has been shown to suppress appetite. The walkers did not have increased peptide YY levels; their appetites remained hearty.
So to eat less, run first.
But on other measures of health, new science shows that walking can be at least as valuable as running — and in some instances, more so. A study published this month that again plumbed data from the Runners and Walkers Health Study found that both runners and walkers had equally diminished risks of developing age-related cataracts compared to sedentary people, an unexpected but excellent benefit of exercise.
And in perhaps the most comforting of the new studies, published last month in Arteriosclerosis, Thrombosis and Vascular Biology and again using numbers from the versatile Runners and Walkers Health Study, runners had far less risk of high blood pressure, unhealthy cholesterol profiles, diabetes and heart disease than their sedentary peers. But the walkers were doing even better. Runners, for instance, reduced their risk of heart disease by about 4.5 percent if they ran an hour a day. Walkers who expended the same amount of energy per day reduced their risk of heart disease by more than 9 percent.
Of course, few walkers match the energy expenditure of runners. “It’s fair to say that, if you plan to expend the same energy walking as running, you have to walk about one and a half times as far and that it takes about twice as long,” said Paul T. Williams, a staff scientist at Lawrence Berkeley National Laboratories and the lead author of all of the studies involving the surveys of runners and walkers.
On the other hand, people who begin walking are often more unhealthy than those who start running, and so their health benefits from the exercise can be commensurately greater.
“It bears repeating that either walking or running is healthier than not doing either,” Dr. Williams said, whatever your health goals.
