People who have been engaged in a certain occupation for a long time often have a variety of occupational diseases. For example, clerks can cause cervical reflexion, lumbar disc herniation, mouse elbow, and people who have been engaged in gas welding, mines, scientific research, etc., often have cardiopulmonary weakness or even lesions due to harmful substances.

Athletes who represent the "stronger, higher, and farther" functions of the human body are not as healthy as everyone understands, and they will also be forced to operate in a professional position for a long time, resulting in continuous compression of local tissues and organs and causing lesions, and occupational diseases exclusive to athletes.

As far as diving is concerned, this sport of constantly falling vertically from high altitude to the water surface has brought high-intensity body impact. Professional divers often wear a variety of sports tapes to help immobilize and heal strained muscles. From the waist and legs to the shoulders and elbows and neck, it is very common, because the muscles involved in diving are so rich.

Yao Aijun is very concerned about this. After being reborn, he also designed his training to be more protective of his body, and would not cause excessive strain to this still developing body. But muscle protection can be strengthened with control exercises, and the eyes are a bit more difficult.

Physiologically, the protective muscles of the eyes are very weak. In addition to the connection of the eye socket, only a thin layer of eyelids shields the external impact, and behind the eyelids is a puddle of "water" wrapped in fragile membranous structures such as the cornea, sclera, retina, and choroid, infiltrated by the tear glands, and the naked eye becomes a window to communicate with the world.

It's just too fragile, and there's no way to strengthen it better.

After Yao Aijun was reminded to "open his eyes and enter the water", he suddenly thought of a lot. In my previous athletic career, I did seem to have encountered such examples, but they were far less striking than muscle strain, and they were often unaware. There used to be talented team members, but in the process of growing up, they suddenly disappeared like meteors, as if it was because of the habitual detachment of the retina.

Yao Aijun thought about the consequences of his damaged eyes for a while, and suddenly a cold wind penetrated into his heart in the winter.

Really, it's horrible.

After the training, Yao Aijun went home with a stomach full of doubts, until he lay in bed in the evening after finishing his homework and washing. There is still a long way to go, and I have to stand longer and longer in this arena, what should I do in such a situation?

It is rare that Yao Aijun, who has a super good sleep quality, did not fall asleep until most of the night with his eyes open.

Yao Aijun, who had some insomnia, turned over and took out the tape of the competition from his collection and put it away. After his financial situation improved, he couldn't wait to buy the video recorder, a "luxury of the times", although he knew that it would be replaced by various VCDs, DVDs and computers in the near future, but at this time it was still the only small household appliance that could play images.

For later generations who are accustomed to watching high-definition, the picture released by the video recorder tape is really picturesque, fortunately, these competition tapes of Yao Aijun are all turned out of the TV station by the trustee, relatively speaking, it is already a boutique that can be found. Live videos of sports are hard to find on the market.

As the contestants in the video jumped up from the jumping platform or springboard, the churning figures and the blue waves seemed to have amazing charm, which made Yao Aijun's uneasy mood settle down little by little.

So many players, so many people, all fascinated by the same event, day in and day out.

I don't know how long I watched it, the boxes of the videotapes were scattered and stacked in a pile around him, and Yao Aijun suddenly stared at the screen and smiled. The screen shows an acquaintance, and his figure appears no less than ten times in the pile of tapes on the ground. The future veteran is still quite young, but Yao remembers that he held on the platform for 25 years.

In addition to him, there are many famous players at home and abroad, all of whom have a sports cycle of more than ten years or even more than twenty years. My current worries seem to be a bit mediocre, even when I walked to the world stage in my last life, didn't my eyes be good......

However, the mentality of adults is always more responsible for their own bodies, and since doctors have issued such warnings, the harm of occupational diseases is bound to exist. Panic is not necessary, but it is necessary to face up to the possibility of a potential threat to your career.

After figuring it out, Yao Aijun turned off the video recorder, cleaned up the mess, and went to make up for sleep with peace of mind.

In the days that followed, there was one more exchange of letters between Yao Aijun and Professor Xu, who was far away in Beijing.

When empirical means are not enough to help oneself, turn to scientific means. This is what Yao Aijun learned in his former national team.

Sports are not simply a competition between athletes and coaches, and the competition between countries is increasingly a competition of scientific research content.

For example, do you remember the banned use of "shark skin"? One-piece windproof sportswear in athletics...... Even the so-called "anti-doping agencies" of various countries, how can you react without first researching......

Professor Xu is engaged in theoretical research, and his field of expertise is in the direction of fluid mechanics. Although he is usually very busy with work, his correspondence with Yao Aijun has always maintained a stable frequency. He enjoyed the correspondence with Yao Aijun, and in his opinion, this young student always had all kinds of whimsical ideas to tell him the direction of theoretical application in the field of sports.

The question Yao Aijun asked this time was a bit beyond the scope of his discipline. Professor Xu interestingly passed the letter to a friend he knew who was doing biology research, which he had promised Yao Aijun to help him contact teachers in other disciplines if needed.

After Yao Aijun had been thinking about it for more than a month, he received feedback from Professor Xu. The biology professor gave me the solution – do you close your eyes when you enter the water......

Well? Close? Close......

When Yao Aijun received this answer, he couldn't cry or laugh. It's really a solution that anyone can think of.

The professor's reply letter was also very detailed, for fear that Yao Aijun would not be able to understand it, so he used very popular expressions. At this stage, unless you wear protective gear, the eye structure is very difficult to exercise, because its own physiological structure determines that the eye organ cannot be strengthened from birth.

And the equipment of the diving event has no other protective gear except for swimsuits and swim trunks, and no one will wear even a swimming cap - the impact of jumping off the high platform, the swimming cap has long been unknown where to fly, and the loose swimming trunks can be washed off, okay?

In this case, the only thing that can protect the eye area is the eyelids. So the best solution, young man, is to close your eyes!

The professor, who was very interested in communicating with the young students, also drew a huge eye structure diagram in the letter, and wrote the words "close your eyes" on the side. What a childlike professor......

Although the feedback he received was a bit beyond expectations, Yao Aijun still wrote back to the person very seriously, thanking them for their help in their busy schedules, and piggybacking on some ideas for other sports injuries that he usually has. Professor Xu has opened a door for himself, isn't this a good way to get to know him?

After getting the theoretical analysis data, Yao Aijun thought about whether to study the improvement of the technical standard of "opening his eyes to water"? Since you can't adapt to the technology by strengthening the body, what you can do is to improve the technical solution. Whether it's for yourself or for the young players who will be engaged in this sport in the future, such as Dabao Xiaobao, it is always good to reduce injuries.

Chen Kangping has recently been keen to take the young students of the new swimming interest class, and he is very relieved to let Yao Aijun practice by himself on the side.

But can anyone tell me what's going on these days? After teaching the new team members the basic movements, he looked up and saw that Yao Aijun's training in the water was simply terrible! Obviously, the movements after the jump are very standard, how can they be slapped on the water as soon as they enter the water, just like a new team member who has just learned to enter the water!
