Hi 112toGuru!
If you're going to do this I recommend switching up between a ball and a desk chair gradually until you get acclimated. Too much of anything too soon is not beneficial.
Also, here are some tid bits of info in case you're interested!
Type of Ball
Purchase an anti-burst ball. These balls are designed to slowly deflate rather than bursting suddenly.This minimizes the risk of injury if your ball punctures.
Size
For Fitness: When purchasing a stability for fitness purposes, find the proper ball size by sitting on the ball. When you sit on a stability ball, your knees and hips should align at 90-degree angles. If your knees sit higher than your hips, the ball is too small, and if your knees sit lower than your hips, the ball is too big.
For chair use: To find the proper stability ball size for use as a chair, measure the seat height of your current chair. Purchase a ball with a maximum diameter that is at least 4 inches greater than your current chair height. You will need the extra size as the stability ball sinks some when you sit on it.
Considerations
Just as with regular desk chairs, people have different preferences when using a stability ball as a chair. You may like to sit higher and closer to the desk while your co-worker prefers to sit lower. You may like a firm stability ball for a chair, as opposed to a softer ball. The height of your desk will also affect what size stability ball works best.
An FYI:
Not all fitness experts agree that using a stability ball as a chair is a good idea. The most common issue is the potential for back injury. Some experts suggest that since your core is contracting while you sit on the ball, and contraction equals shortening of the muscle, this shortening results in increased compression on the intervertebral discs. This sustained compression is not good for the spine and could result in back discomfort or injury. There is also the chance that the unstable stability ball could roll out from under you resulting in possible injury.
I personally don't recommend doing this for more than 3 hours a day
Hope this helps!
would your boss let you use replace you desk chair with a stability ball?
Unprofessional? too weird? Would he/she want the whole gang to get them?
I saw a story a while ago about a teacher who did this in her classroom, they were kids but it had a positive effect, the kids liked them, and they had all kinds of benefits
Would it work the same for adults?
