Fig. 2. Displacement range (A), minimum and maximum velocity (B) and minimum and
maximum acceleration (C) from 8 m s–1 to 12 m
s–1 for dorsoventral (left) and craniocaudal (right) movement
on the level (blue triangles) and incline (red circles) for the six horses.
For each speed category mean ± 1 s.e.m. (displacement) or median and
interquartile range (velocity and acceleration) are calculated from all
strides. A linear function was fitted to the data and is shown as a red solid
line (incline data) and a blue broken line (level data).
