Figure 8
Mean (SD) change in force magnitude characteristics per parameter increment for three muscle models. The linear model (left column), the 2nd Order Nonlinear model (middle column), and the Hill Huxley nonlinear model (right column) are shown at 5, 10, and 20 Hz. Peak force (PF) and force time integral (FTI) for the constant frequency trains (CT) are shown in rows 1 and 2, respectively. Relative doublet (Dblt) to twitch (Tw) PF and FTI, (DT-CT)/Tw, are shown in rows 3 and 4. Significant (p < 0.05) parameter influences (for 5, 10, and 20 Hz inclusive) are indicated by an asterisk (*).
