  Almost 60 years ago Andrew Huxley with his seminal paper \cite{Huxley1957}
laid the foundation of modern muscle modeling, linking chemical events to
mechanical performance. He described mechanics and energetics of muscle
contraction through the cyclical attachment and detachment of myosin motors to
the actin filament with ad hoc assumptions on the dependence of the rate
constants on the strain of the myosin motors. That relatively simple hypothesis
is still present in recent models, even though with several modifications to
adapt the model to the different experimental constraints which became
subsequently available. However, already in that paper, one controversial
aspect of the model became clear. Relatively high attachment and detachment
rates of myosin to the actin filament were needed to simulate the high power
output at intermediate velocity of contraction. However, these rates were
incompatible with the relatively slow rise in tension after activation, despite
the rise should be generated by the same rate functions. This discrepancy has
not been fully solved till today, despite several hypotheses have been
forwarded to reconcile the two aspects. Here, using a conventional muscle
model, we show that the recently revealed mechanosensing mechanism of
recruitment of myosin motors \cite{Linarietal2015} can solve this long standing
problem without any further ad-hoc hypotheses.
