2. Below is plot of the vertical and fore-aft horizontal ground reaction forces during steady state running. Write an equation showing the relationship between the fore-aft ground reaction force and forward velocity of the mass center (2 points). At what points in the gait cycle does forward velocity reach a maximum? Mark these on the plot (2 points). 2.5- Ground reaction forces / Bodyweight -0.5 Right leg vertical Right leg horizontal Left leg horizontal Left leg vertical 0% 50% 100% Gait cycle Figure 1: Vertical and fore-aft GRF during one gait cycle of steady state running
