Comparison of experimental [29] (gray curve) and simulated (black curve) force profiles from maximally-activated muscle undergoing length changes of maximum amplitude $0.05$ (top), $0.1$, $0.25$, $0.5$, $1.0$, and $2.0\hspace{1em}\mathrm{mm}$ (bottom). The maximum isometric force used in the model was $f_{\mathrm{o}}^{\mathrm{M}}\hspace{1em}=\hspace{1em}1.27\hspace{1em}\mathrm{N}$ and the optimal fiber length was ${\ell }_{\mathrm{o}}^{\mathrm{M}}\hspace{1em}=\hspace{1em}17.1\hspace{1em}\mathrm{mm}$.
