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

a

P < 0.05 compared with the corresponding values for control RP (before thin filament reconstitution).

b

P < 0.05 compared with the corresponding values for thin filament reconstitution (before PKA treatment).

c

P < 0.05 compared with the corresponding values for PKA treatment (before sTn reconstitution).
