Fig 1.
Schematic of the experimental set-up at the push-track (top) and on the indoor track (bottom).
The marker-based and markerless cameras are denoted in black and green, respectively. The capture volume at the push-track was ~10 m long and was centred ~10-m from the block (red dashed area). On the indoor track, a ~10 m volume was captured across multiple trials with three different starting positions. This allowed a 0–30 m section to be reconstructed (red dashed area).

Step characteristics during sprinting (red) and pushing (blue) shown as a function of step velocity.
Fig 3.
Paired step characteristic differences for inside and outside leg during pushing (left column) and the corresponding leg during sprinting (right column).
The paired Cohen’s d is plotted on floating axes on the right as a bootstrap sampling distribution. The Cohen’s d effect size is depicted as a dot; the 95% confidence interval is indicated by the ends of the vertical error bar. Top row—SL, centre row—SF, bottom row—SV.
