Comparison of the intersection point’s frequency-dependence from: a Human experimental data (reproduced from [11] with permission) and b Simulation data with best-fit parameters. c The mean of the best-fit simulation data overlaid on the median of the human data from [11]. Within the frequency band from 1.2 to 2.6 Hz for the human data, there was no significant difference (with 95% confidence) between the mean of the intersection point height and the center of mass height. This frequency band is marked by the shaded region. The high-frequency asymptote (3–8 Hz range) of the intersection point was \(0.479 \pm 0.028\) and \(0.468 \pm 0.021\) for the human and simulation data, respectively (with 95% confidence)
