There’s been a flurry of articles of late about how sitting in a chair on a daily basis can cause long-term damage to our health. It turns out that sitting on an exercise ball isn’t much better. From the New York Times:
When Dr. Callaghan and his colleagues had healthy young volunteers sit alternately on a ball, an office chair, and a backless stool while machines measured muscle activity in their abdomens and lower backs, they found no meaningful differences in the seating options; sitting on a ball did not provide a mini-workout for the midsection.
There was one (very) slight benefit.
Workers on balls burned marginally more calories — about 4 per hour — than those on chairs.
It seems the only way to counter the health implications of sitting all day is to make sure you spend more of your time, well, not sitting.
