Bad posture can be affected by almost anything, and it is the role
of ergonomics to design equipment and design tasks that fit the capabilities
and stature of the human body. Asking a man of 5 feet to place a heavy
object on a high shelf repetitively for a long time is going to result
in a bad posture. Asking a person to sit in a chair that is too small
for them is going to result in poor posture.
Despite what our teachers said about putting in maximum effort, when
it comes to our posture, we should be performing tasks with the minimum
effort.
What makes good posture?
A NEUTRAL/RELAXED POSTURE
When the body is relaxed, with all
the muscles and tendons in a resting state, then it could be said
to be a good posture. But can we ever achieve a neutral posture when
we are working? Unfortunately not. Whether involved in hard physical
labour, or sitting at a computer, our muscles are always working,
even if they are not moving. This 'work' exerts force and strain on
our musculoskeleton, and it is the extent of strain that determines
the effects on the body.
What can be done to improve posture?
