From: Operating length and velocity of human vastus lateralis muscle during walking and running
Operating length and velocity of vastus lateralis muscle fascicles during the active state of the stance phase during walking and running onto the normalised force-length and force-velocity curve (mean and standard deviation; n = 15). Force is normalised to the maximum force obtained during the maximal isometric knee extension contractions, fascicle length to the experimentally-determined optimal fascicle length and fascicle velocity to the estimated maximum shortening velocity. *Statistically significant differences between walking and running (p < 0.05).
