Figure 9From: Development of a mathematical model for predicting electrically elicited quadriceps femoris muscle forces during isovelocity knee joint motionPlots of force-time integrals (a, c, e, and g) and peak forces (b, d, f, and h) of experimental versus predicted forces for six subjects 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). Solid lines in (a)-(e) are the identity lines. R2 values were calculated.Back to article page
