Force and rate constant of force development following 8-Br-cAMP treatment.

<p>(A) The rate constant of force redevelopment at various [Pi] for perfused (circles) and ischemic (triangles) fibers, with (open symbols) and without (closed symbols) 8-Br-cAMP treatment. * <i>P</i><0.05 compared to the control perfused condition. (B) The change in the force per cross-sectional area for perfused and ischemic fibers treated with 8-Br-cAMP. Data presented are average ± S.E.M. * <i>P</i><0.05 compared to untreated ischemic fibers.
