LONDON Here's a new 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.

"We don't have enough evidence yet to say how much sitting is bad," said Peter Katzmarzyk of the Pennington Biomedical Research Center in Baton Rouge, who led the Canadian study. "But it seems the more you can get up and interrupt this sedentary behavior, the better."

Figures from a U.S. 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. Standing up."

Give them enough time and money and they will find that even living is a health hazard. :uhoh: Its about time they found something more useful to do with their time rather than use up the free oxygen. :mad:

That study was funded by the Shoe Store Collective (SHOETEC) , there's a counter study funded by Easy Chair Outlet Co-op (ECOCOP) that suggests that standing for more than 15 minutes a day causes serious knee damage and is to be avoided in the best interests of health. This claim is of course disputed by the Knee Surgeon's Advancement Board (KNESA) who fear a dramatic reduction in referrals. They plan on funding a companion review detailing the benefits of kneeling.

Ah well; That's life! And you won't get out of it alive either!:eek:

Guess that they have to do something with all the research grants they get.:mad:

One does not need to be Einstein, nor need a sientific study to know that a sedentary lifestyle leads to an early death.

In news just in...

READING REPORTS 100% FATAL
A recent study has concluded, that people who read useless scientific studies documented by scientists trying to justify their position, are likely to die in 100% of cases!:eek:

Why do they waste money on such things, we should probably have a cure for cancer by now, or at the very least the humble cold...;)

Yeah, well I sat for 49 years in a aircraft, I am now 72, yes my undercarriage is a bit shot, my knees are starting to sag, I have many skin things burnt off, but other than that I am still basically dangerous! Life is for living fellas, if us old buggers made it, so can you!

Here we go, slagging Airbus pilots again, just because we have a "desk"! :rolleyes:

Wonder if it helps to retract the "desk", will that keep us fitter like those svelt Boeing drivers?;)
