Here’ s a warning from health experts: Sitting is deadly. Scientists are increasingly warning that sitting for prolonged periods—even if you also exercise regularly—could be bad for your health. And it doesn’ t matter where the sitting takes place—at the office, at school, in the car or before a computer or TV—just the overall number of hours it occurs.
Research is preliminary, but several studies suggest people who spend most of their days sitting are more likely to be fat, have a heart attack or even die.
In an editorial published this week in the British Journal of Sports Medicine, Elin Ekblom-Bak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define physical activity to highlight the dangers of sitting.
While health officials have issued guidelines recommending minimum amounts of physical activity, they haven’ t suggested people try to limit how much time they spend in a seated position.
"After four hours of sitting, the body starts to send harmful signals," Ekblom-Bak said. She explained that genes regulating the amount of glucose and fat in the body start to shut down.
Even for people who exercise, spending long stretches of time sitting at a desk is still harmful. Tim Armstrong, a physical activity expert at the World Health Organization, said people who exercise every day—but still spend a lot of time sitting—might get more benefit if that exercise were spread across the day, rather than in a single bout.
That wasn’t welcome news for Aytekin Can, 31, who works at a London financial company, and spends most of his days sitting in front of a computer. Several evenings a week, Can also teaches jiu jitsu, a Japanese martial art involving wrestling, and also does Thai boxing.
"I’m sure there are some detrimental effects of staying still for too long, but I hope that being active when I can helps," he said. "I wouldn’t want to think the sitting could be that dangerous."
Still, in a study published last year that tracked more than 17,000 Canadians for about a dozen years, researchers found people who sat more had a higher death risk, independently of whether or not they exercised.
Figures from a US survey in 2003-2004 found Americans spend more than half their time sitting, from working at their desks to sitting in cars.
Experts said more research is needed to figure out just how much sitting is dangerous, and what might be possible to offset those effects.
"People should keep exercising because that has a lot of benefits," Ekblom-Bak said. "But when they’re in the office, they should try to interrupt sitting as often as possible," she said. "Don’t just send your colleague an e-mail. Walk over and talk to him. Stand up." [br] If someone spends most of his days sitting, the following will be likely to be caused except______.
选项
A、he will be likely to be fat
B、he may have a heart attack
C、he may have a stomachache
D、he may even die if sitting too long
答案
C
解析
细节题。根据题干中的“If someone spends most of his days sitting。”可定位至第二段“Research is preliminary,but several studies suggest people who spend mostof their days sitting are more likely to be fat,have a heart attack or even die”,由此可知,每天大部分时间都处于静坐状态的人更容易发胖、患心脏病甚至死亡。但文中并没有提到久坐会引起胃痛,故选择C项。
