<< You have to remember that the COP is nothing more than an "average" point
of
force. It seems as if you are making it into something more. If you chose
to walk on your heels the COP would be only under your heels. Is this
abnormal? When the COP is on the heel and posterior to the ankle joint,
ground reactive force will be trying to plantarflex the ankle joint.
Whether
or not the ankle joint plantar flexes is dependent on how hard the anterior
tibial muscle is working. COP tells us what the ground is trying to do to
the foot. It does not necessarily tell us what the foot is doing. >>
Your second sentence is the pertinent one. What I am saying is the opposite.
The CoP has some use but it is limited because it is nothing more than an
average point.
