[pct-l] Foot, ankle, leg pain, shin splints, etc.

[Yoshihiro Murakami]

The American people seems to dislike science, therefore I post briefly.

This is an simple illustration of human walking models: Six determinants of
gait and Inverted pendulum models.

The six determinants gait model was believed to be true for a long time
without evidence. If we walks as like this model, the energy consumption
becomes very large, therefore this model is not true.

The inverted pendulum model was recently revised and believed to be true,
because the energy consumption of human walking fits to this model.

The energy consumption of walking increase proportionally to the  body
weight ( + pack weight ), therefore, at first, the body weight should be
lightened.

Generally speaking, the American people has huge muscles, which was not
needed for walking. The huge muscles contributes only to energy consumption.

I have posted the video of passive walking robot  last year.
