Figure 3

Mean values of required COF, speed, and step length by age group for the five gait conditions tested. Solid brackets compared between age groups within each gait condition. Dotted brackets compared between Slow-Constrained and Fast-Constrained conditions to investigate the independent effect of speed on required COF. Dashed brackets compared between Fast and Fast-Constrained conditions to investigate the independent effect of step length on required COF. * = statistically significant (p≤0.05). n.s. = not statistically significant. O = Older group. Y = young group.
