Fig. 3. Stance duration as a function of speed. Values are means ± s.d. of individual horse mean data for lead and non-lead limbs (indicated by different symbols) and fore- and hindlimbs (red and blue, respectively) for the six horses for which complete data sets were available. Quadratic lines of best fit (P<0.001) are shown. These were estimated for the population using mean data. Coefficients: forelimb b₀=270.33, b₁=-19.1 and b₂=0.5047; hindlimb b₀=243.56, b₁=-17.426 and b₂=0.4591.
