Fig. 7. Individual stride data of three typical horses for roll (blue), pitch (green) and heading (red) displacement (A), velocity (B) and acceleration (C) of the estimated CoM. Data presented are individual strides between 14.5 m s^-1 and 15.5 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).
