Maximal force was obtained by activating muscle at pCa 4.5 before plotting of the force-pCa curve at each condition.

^aP < 0.05 compared with the corresponding values for control PLV (before thin filament reconstitution or PP1 treatment).

^bP < 0.05 compared with the corresponding values for thin filament reconstitution or PP1 treatment (before PKA treatment).
