Kinematic parameters of the center of mass (COM) at the instant of take-off from experimental data and from the nominal simulation. Parameters d and α describe the position of the COM with respect to the toe, and v and θ, respectively, describe the magnitude and direction of the COM velocity vector. Horita [23] and Wakai [24] reported results using the mean and standard deviation (Mean ± SD); Ashby [22] reported results using least squared mean and a 95% confidence interval (LSM ± 95% CI). Results that were not reported are denoted by NR.
