<i>In vitro</i> specific maximal force production obtained at pCa 4.5 from GAS (A) and EDL (B) skinned muscle fibers at optimal sarcomere length.

<p>Maximal isometric steady-state force generation was significantly lower in Tg(<i>TPM3</i>)^Met9Arg (○) as compared to WT fibers (•) for both GAS (n = 49 for WT and n = 50 for Tg(<i>TPM3</i>)^Met9Arg) and EDL muscles (n = for 50 WT and n = 48 for Tg(<i>TPM3</i>)^Met9Arg). Values are presented as the mean ± SEM. Significantly different between groups *<i>P</i><0.05.
