Because their leg muscles are very developed, the forelimbs are shorter than the hind limbs, and the slender hindlimbs are usually folded up, and when they want to move, they stretch hard and bounce out, which is very similar to springs, and the function of the forelimbs is like the shock absorber of a car.
The same is the impact used to land after a slow jump.
Frogs have four legs underneath their bodies, short front legs, long hind legs, and webbed between their toes. The webbing opens when kicking, just like a fan, inciting the air, it produces force, and the effect of force is mutual, so that the frog can make up for it when jumping, and it can jump high and far. Frogs are slimmer and are more good swimmers.
The neck is inconspicuous and has no ribs. The ulna and radius of the forelimbs.
Healing, tibia and fibula of the hind limbs.
heals, so the claws do not rotate flexibly, but the limbs are muscular. The most primitive frogs began to evolve in the early Triassic. The first frogs to jump appeared in the Jurassic period.
Because frogs are known to insects and other invertebrates.
It is a staple food, so it must inhabit the water's edge. There are about 130 species of frogs in China, and almost all of them are experts at eradicating pests in forests and farmlands. When they squat, their curled hind leg bones are on the same bevel as their protruding vertebrae.
The angle of leaning forward also limits the angle at which they can jump - they cannot jump vertically upwards.
When jumping forward, a closer look reveals that its hind legs are straight when it is in the air. In this way, the frog in the air is big in front and small in the back, like the tail of a comet. From the frog dissection experiment, it can be seen that the leg bones of the frog's hind legs are not thick, but the muscles of its thighs are abnormally developed, and there are no muscles at its knee joints, but all white "tendons".
Compared to humans, its thigh muscles are much more developed than ours. It should be its shape that reduces air resistance.
The muscles and tendons in its legs provide it with explosive power, so it jumps far.
-
Those long legs, those muscles, in this case, the bouncing power is comparable to that of people? And the frog is so small, it is easy to jump.
-
According to my observation, people with long legs generally run fast and jump far, and frogs have long legs and so many muscles, it is difficult not to jump far.
-
Naturally active legs, born for bouncing.
-
Muscular, long legs, born with good genes, no way, excellent bodybuilder in the animal kingdom.
-
Frogs have well-developed leg muscles, which is what makes them very flexible both on the ground and underwater.
-
The legs are muscular and have a strong bouncing power.
-
The legs are muscular, and the forefoot grip is strong and shock absorbed.
-
Frogs are particularly muscular, especially the gastrocnemius muscles in the legs.
-
The well-developed muscles of the legs of the frog No. 1 are also.

Jump jump.
The frog body can be divided into 3 parts: head, trunk, and limbs. Frogs have four toes on their front feet and five toes on their hind feet, as well as webbed. On either side of the frog's head are two small bags that bulge slightly.
That's its eardrum, through which the frog can hear sounds. The frog's back is green, smooth, soft, and patterned, and its belly is white.
You can hide it in the grass, make it easier to catch pests, and you can also protect yourself. It's also helps it breathe. Its air sacs are only found by male frogs. Frogs prey on their tongues, which have mucus on their tongues.
Limbs. The forelimbs are short and consist of 5 parts: upper arm, forearm, wrist, palm, and fingers. 4 fingers, no webbing between fingers.
During the reproductive season, there is a bulging protrusion on the inside of the base of the first finger of the male frog, which is called a marital tumor, which is used for holding the right. The hindlimbs are long and well-developed, and are divided into 5 parts: femoral, tibial, tarsus, metatarsus, and toes. 5 toes, webbed between the toes.
There is a stiffer keratinized distance on the inside of the first toe.
The nerve cells of the frog retina are divided into five categories, one only responds to color, and the other four only responds to a certain feature of the moving target, and can transmit the decomposed feature signal to the visual center of the brain, the optic parietal cover. There are four layers of nerve cells on the optic parietal cover, the first of which responds to the contrast of the moving target.

Most frogs and toads have much longer hind legs than their front legs. The hind legs of frogs are usually powerful and are used for jumping.
It straightens its hind legs with the powerful muscles of its thighs and pushes itself through the air with a hard kick.
This jump can reach up to 20 times the length of its own body.
Also use the front legs when the frog walks on the ground. The front legs are not straight when jumping.
-
When the frog jumps, it kicks the ground with its back legs and jumps instantly.
-
As for how to jump frogs, I suggest that we don't need to be so professional. Frogs are more developed muscles on their hind legs, which can kick the ground and pick them up, and then land on the ground. If you haven't seen it, you can look it up online**! Then you will understand: "I see. ”

**V's lonely my hair I math forehead feel feelings.

Frogs aren't the world's best jumpers like copepods, but they're just as good at jumping. In the frog family, some smaller members can jump up to 10 times their body length.
According to a recent study published in the Proceedings of the Royal Society, the secret to the frog's powerful jumping ability lies within its leg muscles, which are far more flexible than those of mammals. Before jumping, the frog challenges the laws of physics by putting itself in a crouching position while stretching its hind limb muscles. This stretching allows the frog to generate incredible mechanical energy and strength, and finally escapes a potential threat with a stunning leap.
-
Don't look at the frog as stupid as it looks, it's smart! It has bulging eyes, a triangular head, and a sluggish crawling movement, but its bouncing power is top-notch. As soon as you get closer, they will jump, up to 20 times their length.
And he's also a master swimmer, because we learned the breaststroke in swimming from others. Sometimes, animals are the best teachers of humans.
-
Now we will discuss the jumping of a frog. Suppose its take-off angle is and its take-off speed is, just ask how high it can jump.
Solution: Substitute into the question. Therefore, when the frog takes off at the initial velocity and the angle of take-off, the maximum height it will reach is meters.
-
There are many varieties of frogs, and the jumping ability of different varieties of frogs is different, and the average frog can only jump 1-2 meters away. Although it doesn't seem to be particularly far, the frogs themselves are not very large, and they can be said to be ten or even dozens of times the length of their bodies so far away, which shows that their jumping ability is very strong. There are also frogs that are very good at jumping and can jump up to 3 meters or even further.
Frogs are an animal that can be seen in daily life, they are amphibians and often inhabit the water's edge. When the frog is moving, it jumps. Moreover, they can jump high and far every time.
Specifically, frogs contain many species, and the differences between varieties are very significant, and the height that these frogs can jump at is not exactly the same. The average frog can only reach 1-2 meters per jump. Although it doesn't seem particularly far, it needs to be taken into account that the size of the frog itself is relatively small, 1-2 meters is already ten or even dozens of times the size of their body.
However, there are also frogs that are better at jumping, and they can jump a little farther, reaching 3 meters or more. For example, bullfrogs are one of the types of frogs that are very good at long jumps and can jump very far.
As mentioned above, frogs are very capable of jumping, and they can even jump ten or even dozens of times the length of their own bodies. The fact that frogs are able to jump so far has a lot to do with their well-developed legs. The leg muscles of frogs are very well developed and very flexible, much stronger than those of mammals.
Before the frogs jump, they squat down and try to stretch their leg muscles so that they can use the strength of their leg muscles to jump very far. In fact, frogs don't just jump far, they also jump higher.

1.What is Frog Jump?
Frog jumping is an act of frogs. Frogs belong to amphibians, and jumping locust rulers is one of their main ways of locomotion. Frogs move their bodies by bouncing on their hind limbs, and the distance and height of the jump vary from breed to breed.
2.The principle of frog jumping.
The principle of frog jumping is to use bones, muscles, and elasticity. Before jumping, the frog accumulates the potential energy of the muscles to the limit by bending its hind legs downward, and then releases the energy to produce a fast, powerful jump.
3.The meaning of frog jumping.
Frog jumping is one of the keys to the survival of frogs in nature. It can help frogs escape, catch food, and find mates. On warm, humid nights, the frog's call can attract the opposite sex, allowing for successful offspring.
4.The Frog Jump Difference.
Different varieties of frogs have their differences when it comes to jumping. Blue-bellied frogs and tree frogs are able to jump taller, while bullfrogs are able to jump farther and higher. In addition, some frogs use rollers to jump, and their bodies rotate like a merry-go-round during the jump, which is very interesting.
5.Fun facts about frog jumping.
Frog jumping also has its anecdote in the animal world. In ancient Egypt, frogs were seen as a symbol of life, believing that they could represent water and the revival of life. Japanese samurai used to use the technique of frog jumping in horseback riding competitions to challenge themselves and show their strength.
6.How to play frog jump.
Frog jumping can also be used as a form of recreation. One can make a small frog by placing it at a certain height, and the player needs to bounce the little frog to the target area by stretching and releasing a rubber band. This gameplay combines the principle of frog jumping, which not only exercises the player's patience and hands-on ability, but also increases the entertainment.
7.How to protect frogs.
Frogs play a very important role in the ecosystem, but their numbers are constantly decreasing. In order to protect these adorable animals, we should take measures to limit environmental pollution and maintain the integrity of the wetland environment. In addition, frogs should not be caught or killed indiscriminately, and frogs should not be disturbed as much as possible to live and reproduce.
8.Epilogue.
Frog jumping is a unique way of behaving for frogs and is key to their survival in nature. We should learn about and protect these animals as much as possible so that they can play a greater role in our ecosystem. At the same time, we can also make frog jumping an easy and fun activity in innovative ways.

Frog jumping is a form of lower limb exercise that belongs to aerobic exercise. Frog jump needs to spread the feet apart, and half-squat, the upper body is slightly tilted, the hands are placed behind the body to prepare, when jumping, the two feet are pushed and extended, fully straightening the hips, knees, and ankles, and at the same time the arms swing forward quickly, the body jumps forward and upward, and then lands with the balls of the feet, and bends the knees to cushion, and the hands are re-arranged into a preparatory position.
Frog jumping is an exercise that develops the strength of the thigh muscles and hip joints, improves leg strength, and requires relaxation activities after frog jumping.
Since frog jumping is a vigorous lower limb exercise, the impact on the lower limbs is very large, so when frog jumping training, you need to pay attention not to overdo it, otherwise it will be easy to be injured, such as causing fatigue fracture of the lower medullary bone, or broken cartilage plate of the meniscus of the knee joint.
If you are not yet an adult or are still growing your body, you should be cautious about this frog jump, as it may affect the growth and development of bones.
