TABLE 2.

Architectural gearing ratios during various phases of ground contact for the preferred and non-preferred leg.

Values are medians [25% quartile 75% quartile] (means ± SD) for the top row on which a statistical analysis was performed and means ± SD for all other rows. An architectural gearing ratio > 1 means faster longitudinal muscle velocity than fascicle velocity. To make a fair comparison, for parameters with N lower than 9, only the participants that could be compared between preferred and non-preferred and between series-elastic element shortening and series-elastic element lengthening phases were included, resulting in N = 5 for phases of high longitudinal muscle shortening velocities (gray panel). The p-values in the gray panel are for the comparison between preferred and non-preferred leg. Only three athletes had phases during which the aponeurosis was lengthening at high velocities (white panel). Of these three athletes only one athlete had high longitudinal muscle lengthening velocities during both the series-elastic element lengthening and series-elastic element shortening.
