Why is diving a dangerous sport

Why is diving a dangerous sport? Diving is a thrilling sport. The prevailing competition rules require that men's take-off height is 23 to 28 meters and women's take-off height is 18 to 23 meters. Let's see why diving is a dangerous sport. Why diving is a dangerous sport 1

Diving from high altitude is dangerous because the impact is too great.

Detailed explanation: High-altitude diving is an extreme sport. It takes only a few seconds to "fly" in the air, during which a series of waist twisting and turning movements are performed. When it reaches the surface, the speed will be at least as high as 6 miles per hour. When you fall into the pool, you must ensure that your feet "land" first, and your body must remain absolutely nervous and straight. The huge impact is almost similar to falling on the concrete floor. If you are not careful, the diver may break his skull and die on the spot.

There is a gravitational acceleration under the gravity of the earth. The higher the height, the greater the speed when it reaches the water surface, the greater the impact force on the water surface, and the greater the force on people or objects, so that the human body can't bear such a large force and be destroyed. Of course, it depends on the contact area between you and the water surface. The larger the contact area, for example, if you shoot it horizontally, the greater the force; If you plant it, the total force will be small.

Can you dive in the swimming pool?

Diving is not allowed in general swimming pools, but it is inevitable that some people like to dive in the swimming pool. Some adventurous divers in the swimming pool imitate divers flying off the platform, while others imitate swimmers jumping into the water from the pool. Such diving has great security risks.

But on the surface, it's not feasible. There are so many people in the public swimming pool that divers can easily hit other swimmers, which will not only hurt others, but also make them feel uncomfortable in the hospital for several months. If someone is killed, you will lose your life. For the safety of yourself and others, don't try.

Danger of diving

Divers are prone to danger if they are not professionally trained:

1. Corneal injury

When diving, eyes will be impacted, because divers have been trained for a long time, so they don't wear swimming glasses. As for inexperienced people, I remind you to wear your swimming glasses safely to avoid corneal injury.

2. Spleen rupture

People who dive often have incorrect postures, and it is easy for their stomachs to hit the water first, which may hurt their internal organs and even lead to fatal consequences such as spleen rupture.

3. Cervical spine injury

Most cervical spine injuries in diving are caused by improper diving. For example, when jumping from the starting platform, the platform is weak, or the entry point is too close, or the hip joint is not straight when stepping on the platform, or the entry angle is too large, or the swimmer is hit when entering the water, and so on. In addition, the swimming pool water is too shallow (less than 2 meters) is also one of the reasons.

If you dive in rivers and lakes, the shallow river bottom or obstacles such as stakes and stones in the water are the main causes of cervical spine injury. Every summer, when the diving head hits the bottom of the river or obstacles, it causes the head and neck to twist, resulting in cervical fracture and dislocation accidents from time to time.

4. Concussion

If the diver's head falls into the pool first, it will lead to a serious concussion, or even a broken skull, which may lead to his death on the spot.

5. Spasms and cramps

When divers touch the water surface, they often encounter spasms and cramps due to the great influence of gravity, and a large amount of adrenaline will flow into the blood vessels.

6. Casualties

Especially remind swimmers that it is more dangerous for those who swim wild in natural waters to dive. This is because the underwater conditions in rivers, lakes and reservoirs are complicated, and there are many water plants and stones, so it is easy to cause casualties when diving rashly.

diving without professional training is a very dangerous thing. If you can't bear your temper, you can go to a professional diving institution to learn, so that your safety can be guaranteed. Why diving is a dangerous sport 2

Without professional training, it is easier to face danger

Ryan, a 22-year-old man from New England, USA, loved cliff jumping, and jumped into a dark pool below from a cliff about 34 meters high, causing tears in his knee ligaments and tendons and had to be hospitalized. Regarding this "extremely unreal" dangerous experience, Ryan said with chagrin, "I often practice gymnastics and running, and < P > I have also tried jumping off cliffs and diving. I was bruised when I jumped off a cliff before. This time I stood on the edge of the cliff, and many people around me encouraged me to jump, so I really jumped. As a result, now that my injured leg can no longer support my body, I realize that I really did something wrong, and I totally deserve it. "

Zhou Fuwei, who now lives in Qingdao, is 35 years old. Because he lived by the sea since he was a child, he is very watery. Later, after professional training and study, he became a fan of high-platform diving for many years. He said: "Diving is a dangerous sport, which requires professional technical guidance, a series of land training and water training. In addition, diving requires high physical fitness, such as not having a history of heart disease, not being afraid of heights, and having good balance ability. It is best not to have any old injuries, such as fractures."

Sports injuries are often inevitable. If you have received professional technical guidance and strict training, mastered relevant skills, and the posture is correct in actual operation, there will be no problems. However, if the movements are not completed in place and the posture is wrong, even professional athletes will inevitably get hurt, and not everyone can try.

Zhou Fuwei also gave some advice to beginners: to strengthen safety education and emphasize the technical essentials of diving and diving, people who have not been trained professionally can't control their posture, and the consequences are very dangerous. There are many people in the public swimming pool, so divers can easily hit others and cause injuries. Before practicing diving, the preparatory activities must be sufficient, and the limbs, back, head and neck and joints must be fully moved.

Don't try diving blindly just because you are good at swimming

Some people think that you can try diving if you are good at swimming, but this is not the case. Swimming and diving are two completely different sports. Swimming is a mass fitness exercise, which can be tried by children and the elderly. Diving is very professional, so swimming well is not necessarily good at diving.

Shen Bin, a 29-year-old swimmer in Shanghai, usually takes time off at noon to go to the swimming pool near the company for exercise. Swimming is for him to keep fit and relieve the pressure of work. He said that some people like to jump into the water from the pool, especially many children, who are very excited when they see the water. "This kind of diving is dangerous. If you don't jump well, you will easily get hurt.

Sprains and bruises are common. If you have a head injury or fracture, you will be in trouble. I remember my swimming coach told me that the depth of professional diving pools is generally more than 5 meters, and some even reach 6 meters. Only this depth can ensure the safety of divers. At present, the water level and facilities of swimming venues that are generally open to the public are mostly below the standard of professional diving. "

As for diving, Shen Bin said, "I began to learn to swim when I was very young. I tried diving under the guidance of my teacher because I was curious, but because I didn't have professional training, I just jumped off the springboard with my feet down. That's it. I felt very uncomfortable after jumping. Diving is really a dangerous sport. Without professional guidance and training, it's best not to do it easily.

Precautions for diving

1. Have a health check in advance.

you should have a physical examination before diving. Anyone suffering from heart disease, hypertension, lung disease, hepatitis, bad cold, eye disease, infectious disease, otitis media, recovery from serious illness and women's physiological period should not dive.

2. It is not advisable to dive when you are full and on an empty stomach.

generally speaking, it is better to dive about an hour after a meal. Diving just after eating a full meal is easy to cause indigestion; Diving on an empty stomach, due to low blood sugar, is easy to cause dizziness and other diseases, leading to accidents.

3. Make preparations.

Before diving, the warm-up activities must be sufficient, and the limbs, back, head, neck and joints must be fully moved. Why diving is a dangerous sport 3

Methods to prevent diving injuries

For beginners, first of all, we should strengthen safety education and emphasize the technical essentials of diving and entering the water. We should not dive in shallow swimming pools or rivers and lakes without knowing the bottom situation. Before practicing diving, the preparatory activities must be sufficient, and the limbs, back, head and neck and joints must be fully moved. In addition, when you go into the water to save people or are eager to salvage drowning articles, you should take the posture of treading water with both feet, and don't take the diving posture with your head low and your feet high.

When rescuing patients, rescuers should be calm, try to hold the patient's head as much as possible during the rescue process, and don't let it swing, bend or stretch the head and neck, and don't massage at will to prevent nerve damage.

Put the patient flat on the ground. If it is difficult to breathe, the contents of the mouth must be removed immediately to keep the respiratory tract unobstructed, and emergency treatment such as artificial respiration should be given. When transporting patients with cervical spine injury, a wooden stretcher should be selected, and the patient should be slowly rolled onto the board by rolling, and someone should hold the patient's mandible and neck with both hands to keep the cervical spine neither stretched nor flexed.

The danger of high-altitude diving

High-altitude diving is a very thrilling diving sport. Athletes take off from a very high cliff or a specially-made ultra-high platform and enter the water after completing aerial movements. The time of "flying" in the air is only a few seconds, during which a series of waist twisting and turning movements are performed. When it reaches the surface, the speed will be at least 6 miles per hour. When you fall into the pool, you must ensure that your feet "land" first, and your body must remain absolutely nervous and straight. The huge impact is almost similar to falling on the concrete floor. If you are not careful, the diver may break his skull and die on the spot.
