    Here's a new warning from health experts: Sitting is deadly.   

Scientists are increasingly  ­­­­61  (warn) that sitting for long periods --   ­­­­62   if you also exercise regularly -- could be bad for your health. And it doesn't matter where the sitting takes place. Several studies suggest people   ­­­­63   spend most of their days sitting are more likely to be fat, have a heart attack or even die.

In an article   64   (publish) 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 (下定义) physical activity   ­­­­65   (stress) the dangers of sitting.

While health officials have recommended minimum amounts of physical activity, they haven't suggested people try to limit how much time they spend in a   ­­­­66   (seat) position.  

"After four hours of sitting, the body starts to send   ­­­­67   (harm) signals," said Ekblom-Bak. She explained that genes   ­­­­68   (regulate) the amount of glucose (葡萄糖) and fat in the body starts to shut down.

Even for people who exercise, spending long periods of time sitting   69   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   70   (beneficial) if that exercise was spread across the day, rather than in a single bout (一回).
