Figure 3. Fast tension recovery.

Simulations and experimental data for a small and fast length step, , applied to a muscle fiber in isometric contraction. The simulated tensions after the imposed step, (red triangles), and after actomyosin re-equilibration, (blue triangles), are shown and compared to the experimental results (circles; data from [33]). All tensions are normalized with respect to isometric tension . Simulated Tension vs. Time traces are shown in the insert at different , is estimated by the tangent method [41]. Mean valuesstandard deviation over 11 trials are shown. Where error bars are not visible, errors are smaller than the symbol width.
