Rabbit psoas (+cTn) | 1.9 | ∼0 | 137.61 ± 8.67b (167.24 ± 13.15b) | 5.66 ± 0.04a | 2.97 ± 0.34a | |

Passive force was obtained at the steady state. Numbers in parentheses indicate maximal force values obtained prior to cTn reconstitution (P < 0.05 compared with corresponding values obtained after cTn reconstitution). nH decreased upon cTn reconstitution (see Table I), consistent with previous studies (Piroddi et al., 2003; de Tombe et al., 2007).
P < 0.05 compared with corresponding values for control rabbit psoas muscle (Table I).
P < 0.05 compared with corresponding values for control PLV (Table I;).
