Plots of mechanical and chemical quantities over time for the simulation setup with fully active contraction (described in Sect. 3) at the marked node in Fig. 2b: a reaction rates $k_{1/6}$ and $k_{2/5}$; b fraction of attached myosin heads $n_{\text{C}}$ and $n_{\text{D}}$; c active stretch ${\lambda }_{\text{a}}$, elastic stretch ${\lambda }_{\text{e}}$ and total stretch $\lambda$ in fiber direction; d active stress $P_{\text{a}}$ and driving stress $P_{\text{c}}$
