Data are means ± SEM. T_min, T_max, pCa₅₀, and n_H represent fit parameters to a four-parameter Hill equation for the absolute tension versus pCa relationship: $T (p C a) = (T_{\max} / [1 + 10^{n_{H} (p C a - p C a_{50})}]) + T_{\min} .$

P < 0.05, effect of SL within the AP- or MLCK-treated group.
