A Mathematical Model of Muscle Containing Heterogeneous Half-Sarcomeres Exhibits Residual Force Enhancement
Figure 5
Sensitivity of residual force enhancement to amount of half-sarcomere heterogeneity.
Residual force enhancement in a fiber composed of 50 half-sarcomeres in series as a function of α, the variation in half-sarcomere strength. Stretch magnitude was 8% of the final length. Note the logarithmic scale on the x-axis. As little as 2% variation in half-sarcomere strength produces 5% residual force enhancement following stretch.
