new YORK (Reuters Health) – research conducted in
Australia revealed who spent much time sitting
front desk or television were more likely to
die for any cause for three years to persons who
a few hours a day were sedentary.
This suggests that replace some of that time in a wheelchair
with physical activity gentle, such as walking and doing the tasks of the
home, would have important benefits in the long run.
“when you tell people how much physical activity
“
should do too must talk about how reducing the
“
amount of hours per day that involves sitting”, said Hidde van der
Ploeg, of the University of Sydney.
Among more than 200,000 older than 45 years, the team of Van
der Ploeg noted that those who remained seated at least
11 hours a day were 40 percent more likely to
die during the study than those who did less than four
hours a day.
Even so, the complainant clarified that does not prove that be of hours
seated shorten life.
But the results are consistent with recent studies that
they suggested that many hours in a Chair
health consequences, said Mark Tremblay, expert
obesity and children Hospital, Ontario physical activity
East, Ottawa.
“sit or lay, especially in front of a screen,
“”
is bad for health regardless of age”, said Tremblay, to
did not participate in the study. He said that people tend to
think that they are fine if they carry out the daily “dose” of
exercise.
But “do 30 minutes of physical activity five days by
“”
week is not insurance against chronic disease”,
said.
The team of van der Ploeg surveyed 220,000 people of
New South Wales, in Australia, between 2006 and 2008. The
participants responded on their general State of health,
How many diseases had, if they smoked and how much time per day
they did exercise and were seated.
Then, the team checked records of mortality of
Australia for almost three years. In this period were killed 5,400
participants (2-3 per cent).
The authors found that the extra associated risk with the
time of sedentary lifestyle is maintained regardless of whether the
participants had normal weight or overweight, of the amount of
hours of work and if had previous illnesses or not, according to
publishes Archives of Internal Medicine.
The author explained that too long on a Chair
affect blood vessels and metabolism by increasing the
fats that circulate in the blood and lower cholesterol
“good”.
“when one is standing or walking, the muscles of the
“
legs are in constant activity, which helps to eliminate the
glucose and blood fats. “When you’re sitting, that
does not happen because muscles are inactive”, added.
