If you're looking for a
seating alternative you may have learned about the yoga ball chair. The
thought is that if sitting on an exercise ball chair for 10 minutes is
good, then sitting on an exercise ball chair for 4 hours is better.
Unfortunately,
although there are benefits from sitting on a ball chair such as
stabilizer muscle recruitment and strengthening, it's just too
difficult to sustain that kind of muscle activity for very long periods
of time such as that required at work.
It may be beneficial
however to sit on a stability ball chair for shorter interrupted
periods of time. Perhaps at your desk at home, or in your kids room for
doing homework.
If
you have a history of back pain or disc injury it is best to consult
your family physician or physical therapist prior to purchasing a yoga
ball chair. A fitness ball may be recommended by a physical therapist
to treat a condition. In these cases the use of the ball as seating
should be prescribed in a treatment or rehabilitation plan, along with
recommendations about the duration of use and any other treatments
provided.
A
1992 study done amongst 310 children aged 8 and 12 used muscle testing
and balance testing to determine if using a yoga ball chair throughout
the school year would have a positive effect. Results of this research
suggest a possible effect of the seating on the back and abdominal
muscles.
Another
study done in 2006 examined muscle activation in 14 muscles amongst a
group of 15 men sitting on a stability ball versus a wooden stool.
Muscle activity and spine position were used to model spine load and
stability. They found no difference in muscle activation profiles of
each of the 14 muscles between sitting on the stool and ball. They
conclude that prolonged sitting on a dynamic, unstable seat surface
does not significantly affect the magnitudes of muscle activation,
spine posture, spine loads or overall spine stability.
A
study using children with attention deficit hyperactivity disorder
found that using a an exercise ball chair resulted in better in seat
behaviour and improved productivity of legible writing
We can conclude that using an exercise ball chair in the class room is beneficial in terms of the following:
