Why diving is a dangerous sport? Diving is an exciting sport. According to the current competition rules, the men's take-off height is 23 to 28 meters, and the 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: scuba diving is an extreme sport. It only takes a few seconds to "fly" in the air, during which a series of waist twisting and turning movements are carried out. When it reaches the surface, the speed will be at least 60 miles per hour. When entering the pool, you must ensure that your feet "land" first, and your body must be absolutely nervous and straight. The huge impact force 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 reaching the water surface, the greater the impact on the water surface, and the greater the force on people or objects, so that the human body can not bear such a large force and be destroyed. Of course, it depends on your contact area with the water. The greater the contact area, for example, if you shoot horizontally, the greater the strength; If you plant it, the total strength will be small.
Can I dive in the swimming pool?
Diving is not allowed in the general swimming pool, but it is inevitable that some people like diving 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. This kind of diving has great security risks.
But on the surface, it is not feasible. There are many people in the public swimming pool, so divers can easily bump into other swimmers, which will not only hurt others, but also make them feel uncomfortable in the hospital for months. If someone is killed, you will lose your life. Don't try for the safety of yourself and others.
Danger of diving
Divers are prone to danger if they are not professionally trained;
1, corneal injury
When diving, your eyes will be impacted, because divers are trained for a long time, so they don't wear swimming glasses. As for inexperienced people, I remind you to wear swimming glasses safely to avoid corneal damage.
2. Spleen rupture
Divers often have incorrect postures, and it is easy for their abdomen to hit the water first, which may hurt internal organs and even lead to fatal consequences such as spleen rupture.
3. Cervical spine injury
Most cervical 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 it is hit by a swimmer when entering the water. In addition, the swimming pool water is too shallow (less than 2 meters) is also one of the reasons.
If diving in rivers and lakes, obstacles such as wooden stakes and stones in shallow river bottom or water are the main causes of cervical spine injury. Every summer, when the diving head hits the river bottom or obstacles, it will cause the head and neck to be twisted, leading to the fracture and dislocation of the cervical spine.
4, concussion
If the diver's head falls into the pool first, it will cause a serious concussion, and even meet skull fracture's bad luck, which may lead to his death on the spot.
5, cramp cramp
When divers touch the water, due to the great influence of gravity on their bodies, they often encounter spasms and spasms, and a large amount of adrenaline will flow into blood vessels.
6. Casualties
Especially remind swimmers that it is more dangerous for people who swim wild in natural waters to dive. This is because the underwater conditions of rivers, lakes and reservoirs are complicated, and there are many weeds and stones, so diving rashly is easy to cause casualties.
Diving without professional training is a very dangerous thing. If you can't stand your temper, you can go to a professional diving institution to study, so that your safety can be guaranteed.
Why diving is a dangerous sport? Without professional training, you are more likely to face danger.
Ryan, a 22-year-old man from New England in the United States, loves cliff jumping. He jumped from a cliff about 34 meters high into a dark pool below, causing tears in his knee ligaments and tendons and had to be hospitalized. Regarding this "extremely unreal" dangerous experience, Ryan said with regret: "I often practice gymnastics and running.
I also tried jumping off cliffs and diving. I was injured when I jumped off a cliff before. This time I stood on the edge of a cliff, and many people around me encouraged me to jump, so I really jumped. As a result, now that my injured leg can't support my body, I realize that I really did something wrong, and I totally deserve it. "
Zhou, aged 35, now lives in Qingdao. Because I lived by the sea since I was a child, I was very watery. Later, after professional training and study, he became a high-platform diving enthusiast 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 no history of heart disease, no fear of heights, good balance and so on. 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 have the correct posture in actual operation, there will be no problem. 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 also gave some advice to beginners: strengthen safety education and emphasize the technical essentials of diving and diving. People without professional training can't control their posture, and the consequences are very dangerous. There are so many people in the public swimming pool that divers can easily bump into others and cause injuries. Before practicing diving, you must be fully prepared and fully move your limbs, back, head and neck and joints.
Don't try diving blindly because you are good at swimming.
Some people think that if you are good at swimming, you can try diving, but this is not the case. Swimming and diving are two completely different sports. Swimming is a mass fitness exercise, and both children and the elderly can try it. Diving is very professional, and good swimming is not necessarily good diving.
Shen Bin, a 29-year-old Shanghai swimmer, usually takes time off at noon to go to the swimming pool near his company to 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, and they are very excited when they see the water. "This diving is very dangerous, and it is easy to get hurt if you don't jump well.
Sprains and abrasions 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 pool 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 lower than the standard of professional diving. "
Regarding diving, Shen Bin said: "I began to learn to swim when I was very young. Because I was curious, I tried diving under the guidance of my teacher. But without professional training, I just jumped off the springboard with my feet down. That's it. I feel very uncomfortable after jumping. Diving is really a dangerous sport. Without professional guidance and training, it is 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 who suffers from heart disease, hypertension, lung disease, hepatitis, bad cold, eye disease, infectious disease, otitis media, recovery from serious illness and female physiological period is not suitable for diving.
2. It is not advisable to dive when you are full and on an empty stomach.
Diving usually takes place about an hour after a meal. Diving just after eating 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. Prepare for the activity.
The preparatory activities before diving must be sufficient, and the limbs, back, head and neck and joints must be fully active.
Why diving is a dangerous sport. Methods to prevent diving injuries.
For beginners, first of all, we should strengthen safety education, emphasize the technical essentials of diving and entering the water, and don't dive in shallow swimming pools or rivers and lakes with unclear information. Before practicing diving, you must be fully prepared and fully move your limbs, back, head and neck and joints. In addition, when you go into the water to save people or are eager to salvage drowning items, you should take the posture of stepping on the water with your feet, and don't take the diving posture with your head down and your feet high.
When rescuing patients, ambulance personnel should be calm, try to hold the patient's head during the rescue process, and don't let it swing, bend or overstretch the head and neck, and don't massage at will to prevent nerve damage.
Lay the patient flat on the ground. If you have difficulty breathing, you must immediately remove the oral contents, keep the respiratory tract unobstructed, and give emergency treatment such as artificial respiration. When transporting patients with cervical spine injury, wooden stretchers should be selected, and the patients should be slowly rolled onto the board by rolling method, and someone should hold the patient's mandible and neck with both hands to keep the cervical spine from being stretched and flexed.
The danger of high-altitude diving
Diving at high altitude is a very thrilling diving sport. Athletes take off from a very high cliff or a specially-made ultra-high platform, complete aerial movements and then enter the water. The time of "flying" in the air is only a few seconds, during which a series of waist twisting and turning movements are carried out. When it reaches the surface, the speed will be at least 60 miles per hour. When entering the pool, you must ensure that your feet "land" first, and your body must be absolutely nervous and straight. The huge impact force 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 reaching the water surface, the greater the impact on the water surface, and the greater the force on people or objects, so that the human body can not bear such a large force and be destroyed. Of course, it depends on your contact area with the water. The larger the contact area, for example, if you shoot horizontally, the greater the force. If you plant it, the total strength will be small.
