Age-related pattern for relative maximal speed in Canis familiaris, Equus caballus, and Homo sapiens. The Moore function is adjusted to the maximal speed performances by age in H sapiens for 100-m track and field International Association of Athletics Federations (IAAF) main events (dark full line (yellow line online), R2 = .99), in E caballus for racing thoroughbred 1.200-m turf events (dark dotted line (green dotted line online), R2 = .99) and in C familiaris for racing greyhound 480-m events (light full line (blue line online), R2 = .99).
