Fig. 4. Mean peak values of the measured and calculated total vertical ground reaction force (F_Ry,total) at walk and trot. Each point is the average of the peak values of F_Ry,total obtained in several individual stance phases of one horse (15 at trot, nine at walk). Left forelimb stance phases were processed separately from right forelimb stance phases, hence each horse contributed two points at walk and two at trot. The dotted line is the line of identity.
