Fig. 4. Individual stride data of three typical horses for craniocaudal (x, blue), mediolateral (y, green) and dorsoventral (z, red) displacement (A), velocity (B) and acceleration (C) of the estimated CoM. Data presented are individual strides between 11.5 m s^-1 and 12.5 m s^-1 at gallop. The grey shaded area indicates the measured aerial time with the alignment being based on the assumption that vertical kinetic and potential energy is constant during the aerial phase (see Materials and methods; Fig. 1).
