Single muscle fibres absolute force, specific force and myosin in vitro motility speed and force. Single muscle fibre absolute force measured at fixed sarcomeric length (A), and specific force (B) in soleus fibres in response to exposure to the ICU condition and BGP‐15 treatment for 5, 8 and 10 d. Single muscle fibre absolute force measured at fixed sarcomeric length (C), and specific force (D) in diaphragm fibres in response to exposure to the ICU condition and BGP‐15 treatment for 5 d. In vitro motility speed (E), force index (F) and efficiency (G) of myosin extracted from soleus single muscle fibre segments expressing the type I MyHC in rats exposed to the ICU condition for 5 d with and without BGP‐15 treatment. Values are represented as means + SEM. *P < .05; **P < .01; ***P < .001
