Walking and running are the most popular physical activities for
American adults. But whether one is preferable to the other in terms of
improving health has long been debated.
主題一：到底走路跟體重哪一個比較好控制體重呢？
即使消耗的卡路里一樣，跑步還是比走路更好控制體重喔！
Why running should better aid weight management than walking is
not altogether clear. It might seem obvious that running, being more strenuous
then walking, burns more calories per hour. And that’s true. But in the
Berkeley study and others, when energy expenditure was approximately matched —
when walkers head out for hours of rambling and burn the same number of
calories over the course of a week as runners — the runners seem able to
control their weight better over the long term.
其中一個原因是appetite!
跑完步會讓一個人比較沒有食慾喔！女生們知道該怎麼做了吧？
One reason may be running’s effect on appetite, as another
intriguing, if small, study suggests. In the study, published
last year in the Journal of Obesity, nine experienced female runners
and 10 committed female walkers reported to the exercise physiology lab at the
University of Wyoming on two separate occasions. On one day, the groups ran or
walked on a treadmill for an hour. On the second day, they all rested for an
hour. Throughout each session, researchers monitored their total energy
expenditure. They also drew blood from their volunteers to check for levels of
certain hormones related to appetite.
After both sessions, the volunteers were set free in a room with
a laden buffet and told to eat at will.
The walkers turned out to be hungry, consuming about 50 calories
more than they had burned during their hourlong treadmill stroll.
The runners, on the other hand, picked at their food, taking in
almost 200 calories less than they had burned while running.
主題二：
走路也有比跑步好的地方：有效降低心臟疾病
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.
