Why can't cheetahs run for a long time?

Lead: The relationship between cheetahs and human beings is profound and complicated, because cheetahs have been respected, domesticated and used throughout human history. Cheetahs can't run for long, so everyone knows why cheetahs can't run for long. Why can't cheetahs run for long? The following is what I collected for your appreciation. I hope you like it.

Why can't cheetahs run for a long time?

First, cheetahs belong to cats, and they have no sweat glands. They can only pass through meat pads, tongue, nose, lips and anus, so we can observe that cats' paws are often wet in hot summer.

Second, because cheetahs generate a lot of heat when they run, these heat must be excreted in time. If the body's heat continues to accumulate, the cheetah will collapse due to overheating. Sweating and exhaling can dissipate heat, but they can't dissipate heat in time and quickly, so they must be stopped at the right time.

A cheetah can only run at high speed for about 3 minutes when hunting, but it can always solve the battle within 1 minute. If it doesn't succeed within this time, it will choose to continue or give up according to the situation, instead of blindly consuming its own physical strength.

Introduction to cheetah

Cheetah is a carnivorous cat and the only species under cheetah. It is divided into 5 subspecies and 1 variety. North African subspecies is the largest, with adult males weighing 29-7 1 kg, with an average weight of 45 kg and adult females weighing 2 1-63 kg, with an average weight of 38 kg. The adult weight of the other four subspecies is generally below 35 kg. Because it looks like a leopard and runs very fast, it is called a cheetah. Cheetah has a unique body structure: flexible spine, semi-retractable claws, small round head, short kiss, slender body and long legs. The hair on the back neck is very long, like a short mane. There are white spots on the eyes, and there are obvious black lines on both sides of the nose and mouth and nose in the inner corner of the eye. The coat is yellowish brown or light yellow, and the snout, chin, chest, abdomen and inner limbs are white; The body surface is covered with black spots, smaller than leopard print, and all are solid. There is a black ring pattern at the third end of the tail.

Habitat in temperate and tropical grasslands, including semi-desert and savanna with sparse trees and bare rocks. Specialized muscles can make limbs swing more, thus increasing acceleration. It is the fastest land animal in the world, and it only takes three seconds to reach the speed of 1 10 km per hour. At the highest speed, their stride is as long as 7 meters. It is a carnivore and its main food is all kinds of antelopes. Wild populations are now distributed in Africa and Iran.

How fast can a cheetah run?

Cheetah is known as the "king of speed", and its speed has long been world-renowned, but no one has ever measured the specific data of cheetah running speed. Until 1957, a photographer named Kurt Ceverin designed an experiment to test the speed of cheetahs. He put a modified bicycle upside down on the ground. A very strong and long fishing line is connected to the wheel of the bicycle, and a bag of meat is tightly tied to the end of the fishing line. People turn the wheel, the wheel drives the meat bag to move, and the cheetah will follow the meat bag.

The experiment began. As soon as the starting gun rang, people began to turn the wheel with all their strength (the speed of turning the wheel was almost to the limit), then the cheetah ran after the meat bag and the stopwatch began to time. After intense experiments, people calculated that the average speed of cheetahs reached 7 1 mile per hour, which was equivalent to about 1 10 km per hour. The test results are published in the newspaper, so people all over the world know that the speed of cheetah has reached 1 10 km per hour. In the process of spreading, some people even say that the top speed of cheetah is 120 km.

With the development of science and technology and the in-depth study of cheetahs, some scientists began to doubt whether the speed of cheetahs is as high as the legend. In addition, the testing tools of 1957 are relatively simple (wheels, stopwatches, starting guns, etc. ), and the error may be large, so scientists intend to use a more scientific and accurate method to measure the speed of cheetahs.

After entering 2 1 century, researchers from Britain installed the most advanced GPS positioning system on 367 cheetahs. After hundreds of tests on cheetah hunting, it was found that the top speed of cheetah was only 93km-far lower than the original110km or120km.

However, despite this, cheetahs are still the fastest cats and animals on land. The reason why cheetah can run so fast is related to its streamlined body, long tail, strong heart and lungs, light bones and other factors.
