Why is it called backstroke? Why is it not recommended to learn backstroke

Backstroke, also known as backstroke, is a swimming position in which the human body lies supine in water. Backstroke includes reverse breaststroke and reverse crawl, because the face is on the water, it is easy to breathe, but swimmers cannot see that they are swimming towards **, and it is easy to go in the wrong direction.

As the name suggests, backstroke means to swim on the back, during the swimming process, the body lies on the water, because it is this back-facing form, so it is called backstroke, and backstroke is one of the easiest ways to swim with the least effort. That's the answer.

Backstroke. Backstroke, also known as backstroke, is a swimming style that lies on the surface of the water and is a swimming style set by FINA. There are mainly "anti-climbing" and "anti-breaststroke", and "anti-climbing" is used by athletes in competitions almost without exception because of its high speed.

During backstroke, the mouth and nose are always on the surface of the water, and it is easy to breathe, but it is impossible to look forward, and it is difficult to orient. In swimming, only the backstroke requires the athlete to start in the water, and all other swimming styles allow diving to start. Thus, in the individual medley, the backstroke is the second stroke, while in the relay medley it is the first.

Backstroke is a way of swimming face up with arm force propulsion, and it is called backstroke because the face is facing up. It is a name acquired by the posture of the swimming.

Because the backstroke is face-up, like a supine position, it is called a backstroke. It's like breaststroke is like a frog swimming.

Because the backstroke is different from other swimming strokes, the difference is that other swimming strokes are body downward, and backstroke is body up, so it is called backstroke.

Because the backstroke is a lying down swim, it is called that.

It's like breaststroke.

Swims like a frog.

Dog planers too. All through animal swimming positions.

The name that came from it.

Because his swimming position is facing the sky, it is called backstroke.

Yang, that is, facing upwards. In that swimming position, the head is up, which is naturally called backstroke.

Because it is a back-down, sky-facing swimming position, it is called backstroke, and it will be more intuitive to use this name.

Good backstroke because this position is that we are facing head up, and then facing back to the pool, which is to wave our arms in the pool, and then let us swim, because it is normal swimming with the face facing the bottom, so this is called.

Yang Yong, mainly because the face is similar to the supine nature, so the posture of swimming with high is called the backstroke.

Well, the backstroke should be used to keep it, so it's called the backstroke, as the name suggests, it's better, and you can also check it if you understand.

Backstroke is a posture of swimming, and there are several postures in swimming, such as freestyle, breaststroke, and Yang Yong, Yang Yong, who is facing the water with his face above the water and his body floating on the surface of the water, with his face facing the sky.

Swimming with your arms moving face up, or swimming directly on the surface of the water is called backstroke.

Because of the problem of swimming posture and the state of swimming, swimming is divided into various names, such as breaststroke is like a frog, and swimming backstroke is back.

The backstroke is a face-up style of swimming, so it is called the backstroke.

Swimming itself is divided into freestyle, backstroke and breaststroke are named according to the posture, breaststroke is like a frog, and backstroke is swimming on the back.

Speaking of backstroke, it is a position that we adopt when swimming, that is, a position with our face up and our back in the water.

Because the human body and face are all facing up, it is called backstroke.

But it is related to the posture at the time of swimming. Yang Yong got up while swimming in the pool.

Backstroke, as the name suggests, is to swim on your back, Yang Yong is a swimming style in swimming, he needs people to float on the water and lie flat. Push the person's body forward with their arms and feet.

The meaning of raising the head Yang Yong's words are that the head is still swimming like this every day, and the water is slippery and slippery, so it is called Yang Yongbei.

Swimming on your back is just facing up, so swimming on your back is just that.

That's because it's face-up, so it's a backstroke, and you can see that when you swim, it's backstroke with your face up.

Reasons why learning backstroke is not recommended:

The backstroke is the easiest stroke to learn after the breaststroke. The backstroke, as the name suggests, is swimming on the back, and the backstroke leg is also a type of whip leg and requires cross-whipping up and down. The backstroker takes turns swinging his hands like a windmill, and the straight arm moves directly to the top of the head to enter the water after the straight arm comes out of the water from the side of the hip, and then grabs, pulls, and pushes the water to the hip side for a cycle.

The disadvantage of the backstroke is that the speed of the backstroke is not as fast as that of the freestyle and butterfly, and it is not easy for beginners to master the balance of the backstroke, so the nose will often get into the water, which will choke on water, and for beginners, it will be uncomfortable to swim because there is no way to look forward.

The advantage of backstroke is that once you have mastered the balance of the backstroke, breathing is not a problem at all, and it is more efficient than breaststroke, and it can also do long-distance backstroke, and can be used as an aid for patients with low back diseases**.

Backstroke, also known as backstroke.

It is a swimming position in which the human body lies supine in water. The backstroke includes the reverse breaststroke and the reverse crawl.

Because the face is on the water, it is easy to breathe, but swimmers can't see that they are swimming towards **, and it is easy to go in the wrong direction. The backstroke is the only position in which an athlete starts in the water, the others jump into the water.

One of the competitive swimming competitions. When swimming, the body is lying on its back, there is no regular restriction on arm and leg movements, and alternate strokes and alternate kicks are used to cooperate with the technique. In the early backstroke, the two arms stroke at the same time and the legs at the same time were combined with water, which was called the reverse breaststroke.

Due to the poor coordination effect and slower swimming speed, by the time of the Fifth Olympic Games in 1912, the Americans hHebner perfected his technique and succeeded in alternating strokes with his arms and kicks with his legs, so that the reverse breaststroke lost its meaning.

Backstroke is a posture of the human body lying on its back in the water for swimming, the birth and development of backstroke technology has a long history, there is a record of backstroke technique in 1794, but until the beginning of the 19th century, the two arms are still used to stroke backwards at the same time when swimming backstroke, and the two legs do the breaststroke kicking action, that is, the present"Reverse breaststroke" 。

Since the advent of crawling in 1902, some people have begun to use crawling-like swimmers with their arms in turns to stroke backwards because of their reasonable and fast crawling techniques. However, it was not until 1921 that the current backstroke technique was first developed.

The backstroke technique makes it easier to breathe because the head is exposed to the water; Lying on the water is more labor-saving. Therefore, it is very popular among middle-aged and elderly people and people with weak constitution.

In 1900, the second Olympic Games began to be an official event. The backstroke includes the reverse breaststroke and the crawling backstroke. The reverse breaststroke is the earliest type of backstroke, which is similar to the breaststroke and the body posture is reversed.

That is, the human body lies on the surface of the water, and the arms are paddled back from the back of the head through the body. The backstroke at the first few Olympics was held in the reverse breaststroke.

At the 5th Olympic Games in 1912, American athlete H. Heebner won the 100-meter backstroke championship with a score of 1 21 2 using the backstroke technique of taking turns with both arms and hitting the water up and down with both legs, showing the superiority of the climbing backstroke technique, while the reverse breaststroke gradually lost its significance in competition.

We all call the dead man drifting in the backstroke, although it doesn't sound good, but it's quite decent!

It can be compared to a boat, and the hands are.

In fact, this question is very easy to explain, you can think of it this way, it is precisely because your question has a certain universality, so it is recommended that you go to Bilibili or other **** search for relevant tutorials, I believe you will find the answer you need soon, I hope mine is helpful to you, thank you.

Explanation of the backstroke.

backstroke]

Upward Facing Swimming Posture Detailed Explanation (1).One of the competitive swimming positions. Because the body lies on the surface of the water, hence the name.

As you swim in, you take turns moving your arms forward through the air to the front of your shoulders and into the water. Then the body is swiped sideways backwards; At the same time, stretch your legs flat and alternately hit the water up and down. (2).

One of the swimming competitions.

Word decomposition Explanation of Yang Yang ǎ face upward, as opposed to "tilt" : look up. Look up.

Admiration: Long admiration. Revere.

Dependence: Dependent. Lead leakage.

Rely on. Snort. Old-time official language language.

In the upper text, it is used before the words "please, pray, and earn" to express respect; In the following text, it indicates the command: Yang is respectful. 服下, refers to the explanation of swimming, which is rotten swim ǒ swim in the water:

Swim. Breaststroke. Backstroke.

Radical : 氵.

One up, one down, one after the other is the backstroke. Under the premise of the standard movement, the competitive acceleration state of the backstroke is about the same as that of the freestyle. Two strokes and six leg strokes, pay attention to the alternating stroke of the two arms and turn the shoulder angle, while the arms have been maintained at 180 degrees, that is, one up and down, one forward and one back.

The leg should also be rotated to match the rotation of the body to ensure the balance of the body.

The backstroke is the most balanced stroke, and in the process of learning backstroke, swimming crookedly is basically a must for everyone. There is no reference for swimming forward in the backstroke, so you must use both arms to stroke evenly and without obvious differences.

Backstroke fit technique

Two-arm coordination technique The two-arm coordination of the backstroke is connected, that is, when one arm stroke ends, the other arm has entered the water and starts to stroke; One arm is in the middle of the stroke and the other arm is halfway through the shift. During the entire arm movement, the arms are almost in the exact opposite position.

The breathing of the arm and breath is relatively simple, usually two strokes and one breath. That is, start inhaling when one arm moves, then do a short breath-hold, and exhale when the other arm moves. There is also a technique of one stroke and one breath when swimming at high speed, but the breathing should not be too frequent, otherwise it will cause insufficient breathing and cause movement disorder.

Arm and leg coordination technologyWhether the arm and leg fit is reasonable will affect the balance and coordination of the whole movement. During the stroke of the arm, the leg kick up and the downward pressure should avoid excessive rotation of the body, so as to maintain the balance and coordination of the body.

It takes a certain amount of skill to learn the backstroke, and here's how to do it:

1. Body posture.

In the backstroke, the body lies almost horizontally in the water, with the chest naturally stretched out in line with the abdomen, the head is submerged in the water, and the face is exposed to the water. As you swim in, your head remains in an upright position, and your torso rotates naturally around the longitudinal axis in response to alternate strokes between your arms.

2. Leg technique.

The movement of the legs in the backstroke has three functions: one is to push the body forward, the second is to maintain the balance of the body, and the third is to keep the body in a high level of posture. The amplitude of the leg hit is slightly larger than that of freestyle. When hitting water, use the hip joint as the fulcrum, and the thigh exerts force, driving the calf and foot to kick up hard.

3. Arm technology.

The technique of the arm is divided into several parts: entering the water, holding the water, paddling, exiting the water and moving the arm in the air, and several actions are carried out coherently. When entering the water, the arm is naturally straightened, and the little finger of the hand is facing down in front of the shoulder extension, and the arm is cut into the water. When the hand cuts into the water, slide outward, then hook the palm up and backward, while the shoulder is rotated inward, the elbow joint is led forward and down, the hand continues to be lifted, and the shoulder girdle muscles are pulled apart, so that the hand and forearm are aligned with the direction of the stroke.

4. Breathing and movement coordination.

Because the face is exposed to the water, breathing is more natural, generally inhaling when the right arm is out of the water, moving the arm to the vertical water surface when the inhalation ends, and then holding the breath, the hand into the water after the uniform exhalation, the hand will be out of the water to the end of the exhalation. The arm and leg coordination action is generally 1 stroke for each arm and 6 strokes for the legs.

Summary. Answer: Kiss hello one, exercise your back.

I think all of us have very high requirements for the body, and if we want to have a more aesthetic body, then we need to take into account the practice of many parts. When we are backstroke, the main force parts are our back and our arms, so if we want to shape a beautiful back, then we can insist on backstroke, which can give full play to the muscle strength of our back and arms, so that the lines of our back are more beautiful, and excess fat is removed. Second, adjust the cervical spine.

Many people have cervical spondylosis, in the backstroke we will feel their cervical spine and their lumbar spine and other parts fully stretched, the body will feel very comfortable, in addition, under the support of water, our cervical spine problems will be well alleviated. If we insist on backstroke for a long time, we will gradually find that we rarely have backache, and we will often feel refreshed. 

Second, the virtual cover adjusts the cervical vertebrae. Many people have cervical spondylosis, in the backstroke we will feel their cervical spine and their lumbar spine and other parts fully stretched, the body will feel very comfortable, in addition, under the support of water, our cervical spine problems will be well alleviated.

If we insist on backstroke for a long time, we will gradually find that we rarely have backache, and we will often feel refreshed. 

Kiss three, regulate endocrine. Many girls have dysmenorrhea problems, but we all know that in fact, backstroke is also helpful for relieving the state of endocrine and regulating dysmenorrhea, especially in summer, the underwater temperature will be much lower than body temperature, so it is more conducive to our fat burning, which can help blood circulation, at this time women's endocrine will change, and the problem of dysmenorrhea will be slowly relieved. Fourth, increase cardiopulmonary function.

When swimming, a very important skill that we all have to learn is to learn to hold our breath in the water, and to learn to control our breathing more flexibly, so people who often backstroke will have a stronger cardiopulmonary function before relieving. And when swimming, we all need a lot of oxygen**, so the heart's pumping ability will be strengthened, and people's life expectancy will be relatively extended. There are many swimming postures, and the backstroke is the most basic entry posture, so we must all lay a good foundation seriously, but although this action is basic, the benefits to us are also very great
