Figure 2. Accumulated (n = 12) length-force plots constructed from the releases imposed on dephospho- (•) and thiophospho-rigor (○) bladder strips.

The initial 40 % of decrease of force in both plots was approximated by linear regression and data are shown together with their confidence limits (P < 0.05). The inset shows the results of fitting of the experimental data to simulated length-force relationships, describing total elasticity of the rigor strip as that consisting of linear in-series with exponential components. Confidence limits for both types of rigor were calculated by varying total stiffness(es) within the limit of ± s.e.m.
