Fig. 7. Stride data (mean ± s.e.m. as shading) of changes in total linear mechanical energy ME_lin(CoM) 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). For illustrative purposes the minimum total energy has been subtracted from external mechanical energy. Estimated aerial phase (vertical grey bar); 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).
