阅读理解 We all know that exercise is good for your health, but some kinds of exercise may be better than others. Running, for example, may help to protect against heart disease and other health problems. Running may also help you live longer. Researchers say it is not important how far you run. It also does not matter how fast or even how often you run. As advertisements for the running shoes Nike say, "Just do it." Recently, researchers studied more than 55, 000 adults. About one fourth of the adults reported running regularly. The study found these runners were considerably less likely than non-runners to die of any form of disease, including heart disease. In fact, the runners usually lived three years longer than the non-runners. This study lasted 15 years. During that time, more than 3, 400 of the individuals died. About 1, 200 of the deaths were linked to heart disease, a heart attack or stroke. Compared to non-runners, runners showed 30 percent lower risk of death by any causes. Also, runners compared to non-runners showed 45 percent lower risk of death by cardiovascular (心血管的) disease. The runners in the study ran between 10 and 16 kilometers per hour. Slower runners, and those who only ran once or twice a week, were helped nearly as much as those who ran faster and further. Researchers looked at the running over time and found that persistent runners(over six years) showed the biggest benefits. To stay healthy, doctors suggest that adults up to age 65 do 150 minutes of moderate (适度的) exercise every week. They say these individuals need 75 minutes of energetic exercise, like running, every week for good health. （1） For running, the most important is that you should       .
