PEER REVIEWED
Abstract

Background
Prolonged sitting time is a health risk. We describe a practice-based study designed to reduce prolonged sitting time and improve selected health factors among workers with sedentary jobs.

Community Context
We conducted our study during March–May 2011 in Minneapolis, Minnesota, among employees with sedentary jobs.

Methods
Project implementation occurred over 7 weeks with a baseline period of 1 week (period 1), an intervention period of 4 weeks (period 2), and a postintervention period of 2 weeks (period 3). The intervention group (n = 24) received a sit-stand device during period 2 designed to fit their workstation, and the comparison group (n = 10) did not. We used experience-sampling methods to monitor sitting behavior at work during the 7 weeks of the project. We estimated change scores in sitting time, health risk factors, mood states, and several office behaviors on the basis of survey responses.

Outcome
The Take-a-Stand Project reduced time spent sitting by 224% (66 minutes per day), reduced upper back and neck pain by 54%, and improved mood states. Furthermore, the removal of the device largely negated all observed improvements within 2 weeks.

Interpretation
Our findings suggest that using a sit-stand device at work can reduce sitting time and generate other health benefits for workers.

Sitting All Day: Worse For You Than You Might Think

by Patti Neighmond
April 25, 201112:01 AM

Yes, exercise is good for you. This we know. Heaps of evidence point to the countless benefits of regular physical activity. Federal health officials recommend at least 30 minutes of moderate exercise, like brisk walking, every day.

Studies show that when you adhere to an exercise regimen, you can improve your cardiovascular health, lower blood pressure and improve metabolism and levels of cholesterol and triglycerides. You can reduce diabetes risk and the risk of certain cancers. And, finally, exercise can help you maintain a healthy weight, which can boost all of these benefits even more.

But now, researchers are beginning to suspect that even if you engage in regular exercise daily, it may not be enough to counteract the effects of too much sitting during the rest of the day.

Epidemiologist Steven Blair, a professor of public health at the University of South Carolina, has spent 40 years investigating physical activity and health.

"Let's say you do 30 minutes of walking five days a week (as recommended by federal health officials), and let's say you sleep for eight hours," Blair says. "Well, that still leaves 15.5 hours" in the day.
Fighting That 'Chained To The Desk' Feeling

People who regularly break up their sedentary time with movement as small as taking one step had healthier waist circumference, body mass index (BMI), and triglycerides than people who didn't take breaks during long periods of sitting. That's what Australian researchers found in a 2008 study.

But how to make a habit out of taking breaks? Toni Yancey's Instant Recess book offers the following suggestions for people who feel chained to their office desks:

* Take a 10-minute activity break at a scheduled time every day.
* Park farther away from the places where you work, shop, play, study and worship
* Take the stairs instead of the elevator.
* Put printers a short walking distance away from your work or study space instead of right next to it.
* Replace desk chairs with stability balls — or use a standing desk to get rid of the chair entirely — to burn more calories while working.
* Fidget, stand up and stretch at intervals during meetings.

Many of us, he points out, have sedentary jobs and engage in sedentary activities after work, like watching television or sitting around a dinner table talking. When you add it all up, Blair says, "it's a lot more sitting than moving."

Blair recently headed a study at the University of South Carolina that looked at adult men and their risk of dying from heart disease. He calculated how much time the men spent sitting — in their cars, at their desks, in front of the TV.

"Those who were sitting more were substantially more likely to die," Blair says.

Specifically, he found that men who reported more than 23 hours a week of sedentary activity had a 64 percent greater risk of dying from heart disease than those who reported less than 11 hours a week of sedentary activity. And many of these men routinely exercised. Blair says scientists are just beginning to learn about the risks of a mostly sedentary day.

"If you're sitting, your muscles are not contracting, perhaps except to type. But the big muscles, like in your legs and back, are sitting there pretty quietly," Blair says. And because the major muscles aren't moving, metabolism slows down.

"We're finding that people who sit more have less desirable levels" of cholesterol, blood sugar, triglycerides and even waist size, he says, which increases the risk of diabetes, heart disease and a number of health problems.

'Our Body Just Kind Of Goes Into Shutdown'

Adam Cole/NPR

Dr. Toni Yancey, a professor in the health services department and co-director of the Kaiser Permanente Center for Health Equity at the University of California, Los Angeles, has worked for years on developing programs to motivate people to get up and move.

"We just aren't really structured to be sitting for such long periods of time, and when we do that, our body just kind of goes into shutdown," Yancey says.

She recommends routine breaks during a full day of sitting. Her book, Instant Recess: Building a Fit Nation 10 Minutes at a Time, offers readers a guide to integrating such activity into the corporate boardroom, school classroom and even at sporting events.

But even if your work site doesn't engage in routine hourly breaks, there are things individuals can do at their desks to break up a day of inactivity and get moving, even if just for a few minutes. Yancey recommends a few minutes of movement every hour.

And she suggests sitting on an exercise ball instead of a desk chair, adding that it helps strengthen the core while improving balance and flexibility. It also requires more energy, so a few calories will be burned.

It may not sound like much, but an Australian study found that these types of mini-breaks, just one minute long throughout the day, can actually make a difference. You can simply stand up, dance about, wiggle around, take a few steps back and forth, march in place. These simple movements can help lower blood sugar, triglycerides, cholesterol and waist size.

"If there's a fountain of youth, it is probably physical activity," says Yancey, noting that research has shown benefits to every organ system in the body.

"So the problem isn't whether it's a good idea," she says. "The problem is how to get people to do more of it."

同意test，很多医生腿有问题，就是因为做手术一站就要好几个小时甚至更多。
图中的美眉还穿高跟鞋，做样子吧。她在高跟鞋上站一天试试？

反对。会脚疼，会静脉曲张。

同时做走路运动...好极了!
哈哈!
