Competitive human sprinters are built like cheetahs and greyhounds, a study has found. Bones in the front portion of their feet are longer than those of non-sprinters, research has shown. Their ankle joints also rotate differently due to a shorter plantarflexor moment arm (pfMA), a measurement of leverage.
