Bar graphs of comparisons between the mean (+ standard error) experimental and predicted peak forces (a, c, e, and g) and force-time integrals (b, d, f, and h) of six subjects used for validation of the isovelocity model. Responses to CFTs with interpulse intervals of 10, 30, 50, 70, and 100 ms (C10, C30, C50, C70, C100), responses to VFTs with interpulse intervals of 20, 30, 50, 70, 80, 100 ms (V20, V30, V50, V70, V80, and V100), and responses to DFTs with interpulse intervals of 30, 50, 70, 100 ms (D30, D50, D70, and D100) at shortening velocities of -25°/s (a and b), -75°/s (c and d), -125°/s (e and f), and -200°/s (g and h) are shown. * = p ≤ 0.05 (see text for details). It should be noted that the experimental data in the figure are means of two trails. Also, note the difference in scaling of the y-axis between panels a, b, c, and d and panels e, f, g, and h.
