Relative isometric force and stiffness after 1000 ms of active shortening. (a) Mean relative isometric forces after active shortening were lower than pure isometric force (HSD, p < 0.05). The fastest active shortening velocity produced a larger mean relative force than the slowest active shortening velocity (HSD, p < 0.05), demonstrating less residual force depression in the fastest active shortening velocity than in the slowest active shortening velocity. (b) Mean relative muscle stiffness after active shortening did not differ significantly among shortening velocities (ANOVA, F = 0.37, p < 0.77). Bars with the same letter are not significantly different (HSD, p > 0.05).
