Characteristics of the experimental data. A: Onset of the double support phase and the thrust phase as a percentage of the time span between subsequent hindlimb midstance events. B: % Congruity was used to differentiate between trials with vaulting mechanics (< 50% congruity) and trials with bouncing mechanics (> 50% congruity). Boxes represent range between first and third quartiles (i.e.. 50% of the data), the line within the box represents the median and the length of each whisker corresponds to the lowest datum within 1.5 IQR (interquartile range) of the lower and 1.5 IQR of the upper quartile, respectively; outliers (more than 1.5 IQR) depicted as open circles; **: significant at the p = 0.01 level; ***: significant at p = 0.001 level; d: Cohen’s d (effect size).
