[B]Too Much Sitting Can Kill You, Study Suggests[/B]

By Maureen Salamon HealthDay Reporter | HealthDay

MONDAY, March 26 (HealthDay News) -- For better health, try standing up more, a new study suggests. Those who spend 11 or more hours a day sitting are 40 percent more likely to die over the next three years regardless of how physically active they are otherwise, researchers say.

Analyzing self-reported data from more than 222,000 people aged 45 and older, Australian researchers found that mortality risks spike after 11 hours of total daily sitting but are still 15 percent higher for those sitting between 8 and 11 hours compared to those sitting fewer than 4 hours per day.

"The evidence on the detrimental health effects of prolonged sitting has been building over the last few years," said study author Hidde van der Ploeg, a senior research fellow at the University of Sydney. "The study stands out because of its large number of participants and the fact that it was one of the first that was able to look at total sitting time. Most of the evidence to date had been on the health risks of prolonged television viewing."

The study is published in the March 26 issue of the Archives of Internal Medicine.

Average adults spend 90 percent of their leisure time sitting down, van der Ploeg said, and fewer than half meet World Health Organization recommendations for 150 minutes of at least moderate-intensity physical activity each week.

The data was collected as part of Australia's 45 and Up Study, a large, ongoing study of healthy aging. Strikingly, the elevated risks for dying from all causes remained even after taking into account participants' physical activity, weight and health status.

Sixty-two percent of participants said they were overweight or obese (a similar proportion to Americans), while nearly 87 percent said they were in good to excellent health, and one-quarter said they spent at least 8 hours each day sitting.

Inactive participants who sat the most had double the risk of dying within three years compared to active people who sat least, van der Ploeg said, and among physically inactive adults, those who sat the most had nearly one-third higher odds of dying than those who sat least.

Because many people must sit for long hours at their jobs, they should make sure a greater portion of their leisure time is spent standing, walking or engaging in other movement, said Dr. Suzanne Steinbaum, director of Women and Heart Disease at Lenox Hill Hospital in New York City and a spokesperson for the American Heart Association.

"Yes, you have to work, but when you go home it's so important you don't go back to sitting in front of the computer or television," Steinbaum said. "After the 8-hour mark, the risks go up exponentially. It's really about what you're doing in your leisure time and making the decision to move."

Several workplaces in Australia are testing sit-stand work stations, van der Ploeg said -- a generally well-received initiative that may be a future option for other offices. "Try ways to break up your sitting and add in more standing or walking where possible," she suggested.

While the study uncovered an association between total sitting hours and death risk, it did not prove a cause-and-effect relationship.

    Get yourself a PET. It's claimed that people with pets live longer. This may offset your sitting . Like anyother single study group, it only tells one story of a multi-facited life we enjoy. A person is more than a single study and has more than one necessary agenda to keep life, alive. A balanced diet in any field is the best scenario for healthy living.

    They are demonstrating the device and presenting ps3 controller studies about it during the Institute of Electrical and Electronics Engineers’ Haptics Symposium. Haptics deals with research about touch, just as optics deals with vision. A patent is pending on the device.The first haptic or touch feedback in game controllers came in 1997 with the Nintendo64 system’s “rumble pack” that makes the hands vibrate using an off-balance motor to simulate wii controller the feel of driving a race car on a gravel road, flying a jet or dueling with Star Wars light sabers, Provancher and colleagues write.His new controller does something additional: it delivers directional cues to the player by stretching the skin of the thumb tips in different directions.“We have developed feedback modes that enhance immersiveness and realism for gaming scenarios such as collision, recoil from a gun, the feeling of being pushed by ocean waves or crawling prone in a first-person shooter game,” Provancher says.The latest game controller prototype looks like controllers for Microsoft’s Xbox or Sony’s PlayStation but with an addition to the controller’s normal thumb joysticks, on which the thumbs are placed and moved in different directions to control the game. In the new controller, the middle of each ring-shaped thumb xbox controller stick has a round, red “tactor” that looks like the eraser-head-shaped IBM TrackPoint or pointing stick now found on a number of laptop computer brands. 8812abc09 0329
