Prolonged Sitting Not Healthy

Excerpts from ABC Health and Wellbeing

Our sedentary lifestyles defy the usual health recommendations of exercising for 30 minutes on most days is supposed to keep you in good health.

If you sit most of your working day - research shows this is not enough.


If you are meeting - or even exceeding - the Australian Government's physical activity recommendations you still need to move more.

Why is sitting so bad?


Researchers are still trying to understand exactly why it is that sitting has such a deleterious effect on our health.

But Thorp says it appears to be related to the enzymes that help to regulate blood fats and sugars, which are released as certain muscles contract when you stand.

"Muscle contraction is a major contributor to many of the body's regulatory processes, such as breaking down glucose, and when we sit our leg muscles are essentially inactive," she says.

"Loss of local muscle contraction during prolonged sitting is shown to 'slow down' the production and activities of key enzymes involved in removing fats from the blood and exercising won't prevent this 'slowing down' from occurring.

"It is also shown to reduce the uptake of glucose from the blood stream into skeletal muscle."

However, you only need to stand up or take a short walk in order for your leg muscles to contract, which can help prevent those key enzymes from being switched off.

"Our group recently reported that breaking up prolonged sitting every 20 minutes with a two-minute walking break ameliorates the adverse effects," she says.

Try getting out of your chair every 30 minutes

To prevent the detrimental effects of sitting all day try getting out of your chair regularly.
For example you could set a timer for every 30 minutes.
Every time there is a phone call use that opportunity to move around. (May even counter balance any detrimental effects of wireless technology.)
