new YORK (Reuters Health) – take a rest to

walk every 20 minutes instead of sitting during

hours helps to reduce the levels of glucose and insulin after

eat, said a study in the last sample of the dangers

of the long periods of inactivity.

Although the results, published in Diabetes Care, not

show if these reductions have lasting benefits on

health, experience peak levels of glucose and insulin

after a meal it is linked to an increased risk of disease

cardiac and diabetes.

“When we sit, our muscles are disused

“

and not are shrinking and helping our body to regulate

“

many of the metabolic processes of the body”, said David

Dunstan, Professor Baker heart and Diabetes Institute

IDI in Melbourne, Australia.

Dunstan and his colleagues have reported previously that the

most people who watch TV four hours or more to the

day are at risk of early death. With this study,

experimented with how stay sitting for a long time

could affect the response to food intake.

After a meal, the blood glucose levels rise,

and then there is an increase in insulin, which helps to the

cells use sugar as energy or store it. Then,

levels start to decline.

In people with type 2 diabetes, this process no is

done correctly because the body does not respond

properly to insulin. After a meal, levels of

sugar and insulin in the blood remain high.

The Group of Dunstan continued to 19 adults overweight than not

upheld it by are they actually much, requesting that they entered the laboratory

and they lay for seven hours while took them

samples of blood every hour.

After the first two hours, ate a drink of 763

rich in sugar and fat calories and sat during other

five hours.

Each person was subjected to three days of experimentation, and

each date was separated by a week or two.

One day, they sat all the time, taking only

breaks to go to the bathroom. Other, they rose and took two

minute break to walk 20 minutes after intake,

and another day, had similar breaks, but with physical activity

stronger.

The days in which they remained sitting without interruption

they resulted in an increase in the levels of blood in the hour

after the intake of about 90 milligrams per deciliter

(mg/dl) to about 144 mg/dl.

In the days that were lifted every 20 minutes, the

blood levels ranged between 90 mg/dl and over 125 mg/dl.

In general, get up and do a light activity reduced

the total glucose of average 24 percent, increase

front of the Group remained seated. This difference was of

nearly 30 percent with moderate or intense activity.

The results were similar with respect to the

insulin. The levels reached its peak about two hours

after the intake, but grew more when people

remained seated.

“What surprises me of these studies is not good to

“”

are the breaks, but how bad is sitting”, said Barry

Braun, Professor of the University of Massachusetts at Amherst,

did not participate in the study.

Added that a good guideline is to try to get up every

fifteen minutes, although only is to give one back in the

room.

What is not clear is whether the reduction of 30 per cent of

glucose and insulin levels will lead to benefits

for health.

“Only studied for one day.” “The next question is whether

can that reduction result in reductions in the

arteriosclerosis”, said Dunstan, whose group is working in

today in an experiment to longer-term.
