Fig. 9. Mean peak values over the stance phase of the measured and calculated vertical ground reaction forces on the individual limbs (F_Ry,i) at trot and at walk. Calculated results were obtained from distal limb lengths, using the force–length relationships of the distal limbs determined with the help of calculated values of F_Ry,i and limb lengths at trot. For each horse there are four data points, but some of these are hidden by others. The dotted line is the line of identity.
