10-15-12: These studies are coming out fast and furious, which I think is great because it gives us more ammo in the fight against hypokinetic disease!!!
A meta-analysis (18 studies and
included a total of 794,577 participants) showed that your risk of
diabetes, heart disease, and death were increased 2x if you sat for long
periods of time.
What's even more disturbing (and
backs up what other previous studies have found) is that this increased
risk is INDEPENDENT of the amount of moderate-to-vigorous PA one gets,
so even if you meet the PA guidelines, you are still at risk if you sit for long periods of time throughout the day.
can you do to protect yourself? Don't sit for long periods of time!!!
Office workers, college students, and other occupations that require you
to sit for long periods of time are at risk so try and take small
breaks every hour or so. Get up and move around, step in place, walk
around your building or block, go up and down the stairs, etc. You could
even play some active video games and have fun while you're
taking a break! It only need be a few minutes to break it up, so active
video games would be a great option for this kind of break.
Just because you get your PA for an hour a day doesn't mean you're safe to sit on your bum for the other 23 hours of the day!!!
