Just as you can be slim and inactive, it’s possible to be overweight and active. But which is better for your health?
Two months ago, an awful lot of us decided it was time to get off our ever-spreading backsides and do some exercise. This new year’s resolution wasn’t just about vanity (虚荣), oh no. The government tells us that obesity (肥胖) has a "severe impact" on our health, and places a "significant burden on the NHS (the National Health Service)", so slimming is practically our duty to our country.
If the fat is already melting away, then lucky you. But what if the exercise doesn’t seem to be working? What if you can now run a kilometre in a minute and a half, yet your weight has hardly changed? Are you a lost cause? Or is it possible to be both fat and fit — not just fit enough to exercise, but fit enough to live as long as someone a lot lighter?
Not according to a 2004 study from the Harvard School of Public Health, which looked at 115,000 nurses aged between 30 and 55. Compared with women who were both thin and active (ie, who reported taking 150 minutes or more of exercise a week) researchers found that obese but active women had a mortality rate (mortality rate is the number of deaths during a particular period of time among a particular type or group of people) that was 91% higher. Though far better than the inactive obese (142% higher), they were still worse off than the inactive lean (5% higher). "This data does not support the theory that if you are physically active, you don’t have to worry about your weight," was the opinion of Frank Hu, who led the study.
A similar picture emerged in 2008 after Harvard-affiliated researchers examined 39,000 women with an average age of 54. Next to active women of normal weight, the active but overweight were 54% more likely to develop heart disease, while the active but obese were in 87% greater danger. "Even high quantities of physical activity are unlikely to fully reverse the risk of heart disease in overweight and obese women without concurrent (同时发生的) weight loss," the authors concluded.
Those who are trying to lose weight through exercise might face the problem that______.
选项
A、they have a much higher mortality rate
B、they can’t run fast enough to lose weight
C、exercise doesn’t work as they expected
D、they face the danger of sudden death
答案
C
解析
根据题干中的exercise将本题出处定位到第3段第2至4句。该处连用了三个疑问句提出运动减肥可能遇到的问题:但是如果运动没起任何作用呢?就算你能在一分半里跑一千米,但是你的体重却几乎没有改变,又该怎么办呢?你是注定要失败吗?综合这三个问题可以得出,运动可能不会像预期的那样起作用,故答案为[C]。文中第4段论述了肥胖且运动的女性与其他女性死亡率的比较,[A]是对其笼统且又绝对的推断,故排除;从文中的“一分半跑一千米”可知,跑步速度已足够快,故排除[B];文中未提到突然死亡的问题,故排除[D]。
