Before revision:  We show, by means of numerical simulations, that the proposed models correctly predict the main features of force generation, including the steady-state force-calcium and force-length relationships, the tension-dependent prolongation of twitches  , the force-velocity relationship.
After revision:  We show, by means of numerical simulations, that the proposed models correctly predict the main features of force generation, including the steady-state force-calcium and force-length relationships, the tension-dependent prolongation of twitches and increase of peak force , the force-velocity relationship.
