...) from 40 to 80% of stance, where it averaged 50 deg for dogs without added mass ( Fig. 3 ). Maximum propulsive force and propulsive impulse were both greatest in HW trials and lowest in NW trials ( Table 2 ; Figs 4 , 5 ). Table 2. Ground force parameters During the later part...

... compare rapid acceleration with high-speed galloping in dogs to investigate the ways in which body and limb posture and ground forces are altered to produce effective acceleration. Seven dogs were videotaped at 250 Hz as they performed `maximum effort' accelerations,starting in a standing position...
