GRFs on individual Asian elephant limbs, normalized to body weight in Newtons (BW), for normal walking (A) and running (B) at dimensionless speeds [= v (g l)−0.5, where v is velocity in ms−1, g = 9.81 s−2, and l is hip height] of 0.30–0.35 and 0.75–1.3 (n = 6 individuals, 48 strides) and velocities of ~1.2 and 2.9–4.8 ms−1, respectively. GRF traces begin with hindlimb contact (compare Fig. 4) and are for the horizontal (Fx: positive, propulsive; open purple squares, forelimb; blue circles, hindlimb) and vertical (Fy: light-green diamonds, forelimb; dark-green triangles, hindlimb) components.
