Abstract

Whether humans minimize metabolic energy in gait is unknown.
Gradient-based optimization could be used to predict gait without using
walking data but requires a twice differentiable metabolic energy model.
Therefore, the metabolic energy model of Umberger et al. was adapted
to be twice differentiable. Predictive simulations of a reaching task
and gait were solved using this continuous model and by minimizing
effort. The reaching task simulation showed that energy minimization
predicts unrealistic movements when compared to effort minimization. The
predictive gait simulations showed that objectives other than metabolic
energy are also important in gait.
