题文
Office workers should know that long periods of sitting at your desk may be a killer. Scientists have shown a new threat from this lifestyle that they call “muscular inactivity (肌肉迟钝)”．Sitting still for long periods of time leads to the buildup of substances (物质) in the blood that are harmful to health. And exercise alone won’t drive them away.
Millions of people spend their days between car，office desk and the sofa in front of the TV. While the bad influences are well rocognized，it has been thought that they can be changed by regular trips to the gym or swimming pool.
Now researchers say that is not enough. In addition to regular exercise，office workers need to keep moving while they work，by making regular trips to the printer，coffee machine or to chat with workmates.
Elin EkblomBak，an expert on health，says research shows long periods of sitting and lack (缺乏) of “whole body muscular movement” are strongly linked to obesity，heart disease and cancer，and a higher risk of death，regardless of (不管) whether they take enough exercise.
“Everyone knows about the health benefits of regular exercise. But what we haven’t realized before is that longperiod sitting down carries an extra risk that cannot be dealt with by taking exercise，” Dr EkblomBak said，adding that sitting still should be recognized as a risk to health.
“It is important to have a fiveminute break from desk work every 45 minutes. Don’t email workmates—walk across the office to give them the message. Take a coffee break or put the printer in the next room. I am a desk worker and I try to do it. It is not difficult but sometimes you get lost in your work and you forget about it.”
However，more studies are needed to confirm the ill effects of sitting for too long and ways of fighting them. But at present they conclude that “keep moving” should be added to the advice to “keep exercising.”
