As the fastest-running feline, the speed of the cheetah has always been celebrated.

For decades, various sources have recorded that cheetahs can reach a maximum speed of 110 kilometers per hour.

So, who measured the 110 km/h speed? Is this data reliable? The time goes back to 1957.

Known as the king of speed, the cheetah has long been known worldwide for its speed, but no one has ever measured the specific data of the cheetah's running speed.

In 1957, a photographer named Kurt Severin designed an experiment to test the speed of cheetahs.

He placed a modified bicycle upside down on the ground.

The wheel of the bicycle was attached to a very strong and long piece of fishing line.

The end of the line was tied tightly to a bag of meat. People turn the wheel, the wheel drives the meat bag movement, and the cheetah will run after the bag.

The test begins. As soon as the starting gun goes off, the man begins to turn the wheel at full power.

Then the cheetah gave chase to the meat bags while the stopwatch started timing.

At the end of the intense test, people calculated that the average speed of the cheetah reached 71 miles per hour, which is equivalent to about 110 kilometers per hour.

The results of this test were published in the newspapers, so the whole world knew that the cheetah had reached a speed of 110 kilometers per hour.

In the process of spreading, some people also said that the maximum speed of the cheetah was 120 kilometers per hour.

With the development of science and the depth study of cheetahs, some scientists began to doubt whether the speed of cheetahs was as high as the record.

In addition, the test tool in 1957 was relatively simple, and the error might be larger.

So scientists intended to use a more scientific and accurate way to measure the speed of cheetahs.

As we enter the 21st century, researchers from the UK have given state-of-the-art GPS positioning systems.

After hundreds of tests on cheetah hunting operations, it was found that the maximum speed of cheetahs was only 93 kilometers per hour.

This is much lower than the original 110 km/h or 120 km/h that people were talking about.

However, despite this, the cheetah is still the fastest-running feline on land. If the world champion sprinters and cheetahs compete in a 100-meter race, the cheetahs can let the world champion run 60 meters first.

The cheetah's ability to run so fast is related to its streamlined body, long tail, powerful heart, and lungs.

Although the cheetah's speed is very fast, the distance it can run is very limited.

Because there is a limit to the energy of the cheetah. If the cheetah keeps running, it will die because of overheating of the body.

All cheetahs that are unsuccessful in five consecutive hunts are likely to be starved to death.

Because the cheetah has no more strength to hunt.

That's why cheetahs are so fast, they just don't want to waste their strength.
