In Christopher McDougall's book about running, which I think launched the chia pudding trend, he has a story about a researcher whose theory is that bipedal motion separates breathing rhythm from gait when running. A quadruped has to breathe in time with their gait, because internal organs push forward into the diaphragm when the front feet land. According to the researcher, this is my jogging humans can stay cool while chasing quadruped prey, which are pushed to overheating and exhaustion.

I once heard that a springbok is a much better long-distance runner than other animals because it breathes automatically while it runs. The running motion directly powers the breathing motion, making it use less energy.

I can't find a quick source to back this up, though.
