Why four legged animals are better sprinters?

Many four-legged mammals can reach considerably higher running speeds than two-legged humans. Animals perfectly adapted to sprinting, such as cheetahs or antelopes, are characterized by a slender body shape, long legs, and a particularly mobile spine to achieve very high speeds when running.

What would increase the mass of animals?

Animals could get bigger either by (1) modifying the material properties of their bones and muscles, (2) changing the geometric shape of their bones, (3) changing the way their bones are loaded, (4) modifying the architecture of their skeletal muscles, or (5) suffering decreases in locomotor performance and simply …
