Force redevelopment following length release.

<p>(A) Representative traces of force after length release for a perfused fiber activated by pCa4.5 solution including varying concentrations of added Pi. The force recovery transients were analyzed by single exponential fits (dotted lines) to determine the rate constant of force redevelopment. (B) The rate constant of force redevelopment for perfused (•; n = 7), ischemic (▵; n = 10) and ischemia-reperfused (□; n = 7) fibers. Data presented are average ± S.E.M. * <i>P</i><0.016 compared to perfused.
