Don't make these mistakes when swimming. Swimming is a very good aerobic exercise for people who love fitness. It can not only exercise our bodies, but also keep in good shape. The following is the information I compiled for you about not making these mistakes when swimming.

Don't make these mistakes when swimming 1 1, as long as you can swim, it doesn't matter.

At present, several internationally recognized standard swimming strokes are breaststroke, butterfly, backstroke and freestyle. However, many citizens have not received professional training, and they have formed a nondescript swimming posture, thinking that they can swim as long as they can swim. This is a misunderstanding, swimming posture will determine whether a person is prone to drowning accidents. If the swimming posture is not standardized, it will consume a lot of physical strength in a short time, and it is likely to be dangerous because of lack of physical strength, such as dog crawling and pole swimming. If you want to learn swimming, you'd better go to a professional swimming training institution and learn the standard swimming strokes, so that they can calmly cope with all kinds of unexpected situations that may occur during swimming and avoid unnecessary troubles.

2. Inflatable swimming ring is very safe.

Most people swim with inflatable swimming rings, which is considered foolproof. But the inflatable swimming ring is just a toy, which is mostly used in swimming pools and shallow waters to assist in learning to swim. If you swim by the river or the seaside, once you encounter rocks or sharp objects in the water, the inflatable swimming ring is easy to leak, which has great safety hazards, and a slight carelessness may lead to drowning accidents. Comparatively speaking, foam swimming rings are the safest. Nowadays, most professional swimming rings are made of foam material, which can bear the weight of one or two hundred kilograms, without leakage or damage, and has high safety. Therefore, when choosing a swimming ring, it is best to choose a foam swimming ring.

3. Those with good physical strength can swim far.

Some swimmers are blind and confident, thinking that if they can swim and have good physical strength, they can swim faster and farther than others. In fact, water is more likely to cause physical loss, so we should start training from short-distance swimming at first, and then slowly extend the swimming distance. Long-distance swimming requires long-term continuous training, which is gradual and cannot be accomplished overnight.

4. How easy it is to get infectious diseases.

Swimming pool is the most exposed public place. Therefore, whether skin diseases mainly transmitted through physical contact can spread in swimming pools has become the most concerned issue. Some experts believe that although the possibility of infectious diseases and skin diseases in swimming pools cannot be completely ruled out, this possibility is very small and there is no need to worry too much. Because disinfectants are usually put into swimming pools for disinfection, when the secretions of patients with skin diseases come into contact with healthy people through water flow, most germs will be killed, so the possibility of infection is not great. However, patients with beriberi and folliculitis should not go to the swimming pool, actively prevent the spread of germs, and at the same time prevent others' germs from aggravating their own diseases.

5, pool water disinfection does not protect skin.

After swimming, many people are used to using strong alkaline lotion in order to achieve disinfection effect. But during swimming, on the one hand, water will degrease the skin to make it look dry, on the other hand, the disinfectant contained in the water will also dry the skin. At this time, if strong alkaline emulsion is used, it will cause harm to the skin. Therefore, it is best to choose some mild bath products and apply moisturizing cream to keep your skin moist.

Don't make these mistakes when swimming. How many swimming positions are there?

improvisational theatre

One of the swimming events. 1896 1 The Olympic Games began to be listed as an official event. Freestyle is not limited by any posture, crawl is the fastest, and crawl has become the only posture of freestyle. Climbing is like climbing, that is, paddling alternately with your arms and kicking alternately with your legs. This swimming posture has reasonable structure, small resistance and even speed, and is the fastest and most labor-saving swimming posture in the world at present.

The basic technical feature of freestyle is that the human body is prone in the water, and the head and shoulders are slightly higher than the water. When swimming in, the trunk rolls around the longitudinal axis of the body properly, and the arms take turns paddling to push the body forward. After the hand enters the water, the paddling route is S-shaped, and the breathing and paddling movements are coordinated. When the arm is paddling hard, use the water flow to inhale in the valley formed on both sides of the head.

breaststroke

Breaststroke is an ancient swimming style. According to records, as early as 2000 ~ 4000 years ago, China, Rome and ancient Egypt had similar swimming styles. 1875 On August 24th, the famous swimmer M weber swam across the English Channel by breaststroke, which lasted 2 1 hour for 45 minutes. /kloc-At the beginning of the 9th century, breaststroke was the earliest posture adopted in swimming competitions. However, due to the slow speed of breaststroke, there are more and more side strokes, crawl strokes and breaststroke. It was not until the 3rd Olympic Games in 1904 that breaststroke was separated from other postures.

butterfly stroke

During the period of 1924 ~ 1936, the biggest innovation of breaststroke was that the arm did not move forward from the water after paddling, but the arm moved in the air but the leg was still clamped by breaststroke, resulting in the deformation of breaststroke-butterfly stroke. In butterfly stroke, the body lies prone in the water, and relies on the powerful arm stroke and leg wave stroke to push the body forward. There is no fixed body posture.

backstroke

One of the swimming events. 1900 The second Olympic Games began to be listed as an official event. Backstroke includes backstroke and crawl. Reverse breaststroke is the earliest backstroke, which is similar to breaststroke and has the opposite posture. That is, the human body lies on its back on the water, and the arm paddles backwards from the head to the side. In previous Olympic Games, backstroke was an anti-breaststroke posture. In backstroke, the body lies almost horizontally in the water, the chest naturally stretches in line with the abdomen, the head is submerged in the water, and the face is exposed to the water. When swimming in, the head always maintains an upright posture, and the trunk naturally rotates around the longitudinal axis due to the alternating paddling action of the two arms.
