How Fast Can a Human Run Amazing Science Fact Videos - Pushing The Limits Ep -01

How fast can a human run Pushing the Limits Series Episode -01. The limit to how fast human can run is 9.48 seconds for the 100-meter race, 0.10 seconds faster than Usain Bolt's current world record, according to Stanford biologist Mark Denny.

Another expert in human locomotion, Weyand says the primary factor influencing speed is how much force sprinters hit the ground with their feet.

When athletes run at a constant speed, they use their limbs like pogo sticks, Weyand says. Once a sprinter hits the ground, his limb compresses and

gets him ready to rebound. When he's in the air, the feet get ready to hit the ground again.

When a runner hits the ground, 90 percent of the force goes vertically to push him up again, while only 5 percent propels him horizontally. In that regard, sprinters behave a lot like a super ball. "What they do is they bounce a lot," he says.

Science and technology are changing the limits to human running speed. Athletes nowadays can take hormone doses to change the mechanical properties of muscles, and scientists have succeeded in tweaking mice's DNAs to alter their muscle fibers.

That speed still won't allow us to outrun an adult cheetah, the fastest land mammal, which can cover 100 meters in less than 6 seconds.
