Distribution of Myosin Attachment Times Predicted from Viscoelastic Mechanics of Striated Muscle
Figure 7
Mean time of crossbridge attachment. (a) The mean time of crossbridge attachment using both models of demonstrated a longer for -MyHC and a prolongation in as MgATP was reduced. The two models agreed qualitatively in these respects, but did not agree quantitatively as estimates using the gamma distribution (GD) model were ~40% higher than those using the single exponential distribution model (SED). (b) Values for using the two models correlated strongly. Despite the relative differences in the estimates of , either model produces similar results for comparing the effects of isoform and MgATP. by -test between MyHC isoforms at same MgATP.
