Figure 4


Fig. 4. Stride data (mean ± s.e.m. as shading, N=6) of the sum of the vertical kinetic (KEdv) and linear potential energy (PE) during level (blue broken line) and incline (red solid line) galloping at a mean speed of (A) 10 m s–1 (n level=56 and n incline=60) and (B) 12 m s–1 (n level=60 and n incline=28). Presented data are averages of all strides from all horses within the speed range. Aerial phases (vertical grey bar) were estimated to be during the time when the curve was approximately constant. Stance phases of individual feet are presented for illustrative purposes as black bars in the lower panels. LF=lead fore; NLF=non-lead fore; LH=non-lead hind; NLH=non-lead hind.
