阅读理解之说明文解题技巧 Running and walking are both excellent forms of exercise. Those who regularly do either usually have healthier hearts, stronger bones and lower body weights than those who do little exercise. But does it matter whether you spend time walking or running? Arguments can be made for both, and which is right for you depends on your goals and your present fitness level. “The key difference between running and walking is how many calories you are burning—not per mile, but per minute of exercise says Paul D. Thompson, a doctor at Hartford Hospital.” “Running is a more-efficient (高效的) movement and it’s more demanding on the body, so it bums more calories per minute,” Thompson says. “But if you’ve got the time to walk long enough to bum the same amount of calories, then walking is fine.” That said, if your final goal is to lose weight, chances are that neither running nor walking alone is going to do the trick. Research has shown that it needs to be done along with calorie control.
