Body velocity, swing height and stance duration before and after the swing phase differ between short and long steps.

<p>The relative frequencies are shown for long (blue) and short (red) steps for each leg type (rows). A: The stance duration before swing is the stance phase immediately preceding the swing movement of the reference step. Stance durations were binned to 0.1 s and cut off at 2 s, with the percentage of longer stance phases given by the number to the upper right. B: Body velocity is the movement velocity of the body origin when a leg lifted off the ground. C: Swing height represents the height range of the tarsus during swing phase, binned to 1 mm bins. The total numbers of steps is given in C (n). D: Stance duration after swing is the stance phase immediately following touch-down.
