Cheetahs on the Edge — Director's Cut

Filmed by Gregory Wilson with a Phantom Flex camera at 1,200 frames per second in 2012. Licensed under CC BY 3.0.

This high-speed video clip of a cheetah running, filmed with a Phantom Flex camera at 1,200 frames per second, shows how fast the cheetah can move by revealing how much ground it covers each second.

A cheetah can reach speeds of 97-113 kilometers per hour (60-70 miles per hour) because of several special features. They have strong, flexible muscles and a very stretchy spine that help them make long, fast strides. Their light, streamlined body reduces air resistance, and their long legs help them run faster.

Cheetahs also have large nasal passages and lungs that take in and use oxygen very efficiently, which is essential for running at high speeds. Unlike other big cats, their claws do not retract and provide constant grip, while their specialized foot pads prevent slipping. Their long, flexible tail helps them balance and make sharp turns.

These features allow cheetahs to speed up from a complete stop to 97 kilometers per hour (60 miles per hour) in just 3 to 4 seconds. However, they can only keep up this amazing speed for about 20-30 seconds because it uses a lot of energy and generates a lot of heat.
