Fig. 7. (A) Plot of front:hind ratio of peak vertical ground reaction force (GRFz) versus peak forelimb GRFz, expressed as percentages. Data are shown for walk (red diamonds), trot (green triangles) and canter non-lead leg (filled blue circles). The linear regression line is fitted to all data (y=1.6198–0.0358x, r²=0.2722, P<0.0000). (B) Plot of front:hind vertical impulse ratio versus peak GRFz, expressed as percentages. Symbols are as for A. The horizontal red solid line shows the mean ratio across all speeds (1.33). The red broken lines indicate ± S.D., and the blue broken lines indicate the inter-quartile range.
