The human foot and heel-sole-toe walking strategy: a mechanism enabling an inverted pendular gait with low isometric muscle force?

We discussed how the inverted pendulum model doesn't describe ground reaction forces observed in-vivo during human walking in 2010 here: http://www.podiatry-arena.com/podiatry-forum/showthread.php?t=47277

I should be interested to hear if this new model achieves similar energetic fluctuations along with ground reaction forces observed in-vivo. "The human foot and heel-sole-toe walking strategy: a mechanism enabling an inverted pendular gait with low isometric muscle force?" Nope, it's a bipedal-spring mass model of walking in which the leg stiffness is modulated within the step.

You still prefer an inverted pendulum model of walking, Kevin?;)

 

Yes, Simon, I do prefer an inverted pendulum model of walking to model the energetics of walking versus running, and still use it in all my lectures on walking vs. running biomechanics.

Energetic Consequences of Walking Like an Inverted Pendulum: Step to Step Transitions

 

Do you include compliant leg behaviour in your walking model?

 

Not specifically in reference to the energetics of walking.

 

OK, so your only using the inverted pendulum model to explain energetics and not reaction forces etc.

 

Correct.
