Cardiac Length Dependence of Force and Force Redevelopment Kinetics with Altered Cross-Bridge Cycling

We examined the influence of cross-bridge cycling kinetics on the length dependence of steady-state force and the rate of force redevelopment (k(tr)) during Ca(2+)-activation at sarcomere lengths (SL) of 2.0 and 2.3 μm in skinned rat cardiac trabeculae. Cross-bridge kinetics were altered by either r...
