Why Humans Can’t Run Cheetah Speeds (70mph) and How We Could | WIRED



Why is it that cheetahs can run so fast? How can humans get to be that fast? Cheetah biologist Adrienne Crosier and orthopedic surgeon Dr. Chris Raynor explain why cheetahs are so quick and why humans and limited comparatively.

Adrienne Crosier is a biologist and manager of the cheetah reproductive and research program at the Smithsonian Conservation Biology Institute. SCBI plays a leading role in the Smithsonian’s global efforts to save wildlife species from extinction and train future generations of conservationists. https://nationalzoo.si.edu/conservation

  1. That cheetah human was lame. All you did was make the muscles bigger. It looked like a 5 year old drawing. Without addressing other issues such as bigger lungs. Also what to do because a cheetah runs with four legs and humans have two.

  2. Sorry to be boring… But, the force created by the cheetahs 2 rear legs unsurprisingly creates more than double the force generated by one of the human's legs when it strikes the ground, and likewise with the pulling action of the front legs. Sprinting is all about the force created on impact, and leg cadence somewhat. The human running style would have to evolve so that the upper body is leaning more forward, and an adjusted centre of gravity created, and the ankle joint would need to be fixed in the extended position and not flexing on impact.
    Nerd I know!

  3. But you won't force a cheetah to do physics.
    We are different species, we can't run as fast as a cheetah, but we also won't expect cheetah to do something such as studying, working or something else.
