Fig. 7. Predicted peak vertical force, normalised to total mass of subject
(including mass of horse, riding tack and rider) as a function of speed
(N=9). Values are means ± s.d. of individual horse mean data
for fore- and hindlimbs (red and blue, respectively). Quadratic lines of best
fit (P<0.001) are shown for the population. These were calculated
for fore- and hindlimbs separately using mean data. Coefficients: forelimb
b0=-2.778, b1=2.1376 and
b2=-0.0535; hindlimb b0=1.3249,
b1=1.5444 and b2=-0.041.
