Very large
animals have more «fast twitch» muscle fibers needed during a sprint and can in theory accelerate for longer periods, but those tissues soon run out of oxygen and thus reach max
performance long before supermassive creatures
ever reach their theoretical maximum speed.
Unprejudiced and positive tests are therefore greatly needed, and these can only be found in show and trials under judges who have the common interest so keenly in view that they will allow neither friendship nor personal bias to control the awards; men who will bear
ever in mind that upon their decision will greatly depend the future reputation of the
animal in the stud, and who will therefore examine carefully each specimen before them, giving due credit to beauty and blood, but in all cases where possible requiring also
performance were they pronounce a favorable verdict».
