    Actually came across this researching information for a discussion in my A&P class. Thank you for the information that helped me pass my assignment! :]

    Thanks jonmatthis for the very nice point made. I know the work that you quote and there are many papers that clarify this point. The audience was extremely general and this is only one of very many simplifications that I made! With best wishes.

    Great talk, but at around 1:55, you say that "if we walked with straight legs, their COM would move up and down, which... is a waste of energy." In fact, the COM during walking DOES follow a regular up and down, sinusoidal path with each step. A person walking with straight legs mimics the dynamics of an inverted pendulum, which is energetically lossless. In fact, walking with a flat COM path costs MORE energy than walking with a sinusoidal one (See Kuo, Human Movement Science, 2007 for more).
