By fine-tuning the center of gravity when pushing the table, the body is assisted to tighten inward more and more when turning. This is a 15-like principle of an eccentric wheel, when the center of gravity is not in the middle at the time of departure, the speed of the connecting body will be turned inward.

Of course, this is a theoretical thing, and it is quite complicated to say. It is to treat the human body as a complex structure, and the force is exerted through the muscles, and the bones attached by the muscles, other limbs other than the exerted parts, and so on.

Through subtle and precise control, you can make the body turn to the angle and inner power you want!

Yao Aijun jumped out, seemingly a little crooked, but he unbelievably maintained an extremely stable self-rotation in the air.

One week, two weeks, two and a half weeks –

The slight difference in the center of gravity brings a better turning effect, the rotating part in the air is incredibly compact, and when turning from the turning body to the tumbling, a slightly offset center of gravity also makes the transition action extremely smooth.

Incredible, simply incredible!

Why does a pedaling platform with a shifted center of gravity not bring about a positioning error?!

I'm afraid that Coach Zhang and Lu Hang, who trained together, will know what the problem is!

At the beginning, when the coach asked Yao Aijun to go to 6245, Yao Aijun was very unhappy.

Although he can jump with such difficulty as an arm stand, it doesn't mean that he can jump well at the moment!

The reason why any difficult movement is difficult is that it challenges the human body. At this stage, for Yao Aijun, he can train hard and study by himself, but he doesn't want to leave hidden dangers in his body that is still developing!

The twists and somerds of 6245 are all emitted from the way the arm stands off the stage, and the motor muscles involved are all the upper limb strength that is still developing in the adolescence, which can easily lead to contusions in the shoulder, hand and even waist.

It's not a level of difficulty that's appropriate at this stage.

Coach Zhang: They are used to having some minor injuries and illnesses in training, which is inevitable in traditional training. In the coach's view, Yao Aijun is far from being such a "squeamish" person, and a little difficulty is the correct "tapping" of potential for him.

This philosophy is here to stay even 10 years later! Man will win the day! This is an important magic weapon that our ancestors loved to use to exemplify the conquest of nature.

Yao Aijun has "experienced" the consequences of such training, and it is not only himself! Naturally, he refused to accept such a "digging" method.

But isn't it normal for athletes to be difficult?

Under the strong pressure of the coach, Yao Aijun couldn't say the reason why he was unwilling to mention the difficulty, so he could only go up.

In order not to burden the body, it is necessary to make the action structure more scientific and reduce the possibility of using "brute force".

How can we make the action more reasonable?

Yao Aijun thought of the semi-finished 5156b of Lu Airlines at the National Games at that time!

At that time, in order to allow himself to twist in the air for three weeks, he stepped on the edge of the platform when he took off, jumped in from the edge, and used the angle to exert force. This point was keenly captured by Chen Kangping, who was sitting below at the time, and greatly admired the way Lu Hang used his brain.

Chen Kangping knew, so he naturally told Yao Aijun to know.

The speaker has no intention, but the listener has the intention!

Yao Aijun, who was still in the provincial team at the time, deliberately found someone to get the video of the competition and watched it repeatedly. I contacted Lu Airlines again to inquire, and I probably figured it out.

It turns out that the deviation of the jump can be used in this way!

With the example confirmed, Yao Aijun wrote to Professor Xu for advice, using scientific methods to interpret the principle of action generation and so on.

Although the powerful Professor Xu does not know how to dive, he is an expert who has been immersed in the field of fundamental physics for many years! Just based on the description in Yao Aijun's letter, I captured the keyword!

Deviate? Revolve?

What else can connect these two words in physics?

This is a phenomenon of dynamic instability and dynamic stability!

In his reply, Professor Xu gave him a lot of explanations and examples on the stability, coordination, and unstable motion of moving objects.

It was like being turned on by someone to open a light, and following the guidance, Yao Aijun understood the movement mode of the eccentric wheel theory.

Although it is generally understood that the movement of the center of gravity may be more beneficial for rotating the piece, the difference between the human body and the object is huge.

In the subsequent training, Yao Aijun deliberately figured it out and kept it in his heart.

When Zhang Changqing wanted to make him difficult this time, he finally used this magic weapon!

Unlike last time, his own people are in Jianghuai, Lu Hang is in the national team, and Professor Xu is still far away. This time, Yao Aijun can be described as the right time, place, and people!

I caught Lu Hang's idea of splitting up his 5156b at that time and the reason for the formation of the action, and took the question to ask Professor Xu, and after taking it back, he was discussing it with Comrade Li Kuanfu.

Practice your ideas on the jumping platform over and over again.

Finally, he figured out how to precisely control himself into an "eccentric wheel" movement that leaps out of the jumping platform!

The 6 groups are arm standing and pushing the body out of the jump platform with their hands.

The only contact fulcrum is the hand!

The hand is one of the most sensitive senses of the human body, far more sensitive and flexible than the foot.

Going out through the trolley table allows for more detailed control.

Yao Aijun polished his movements again and again in practice. It has been a long process from jumping out of the 6245 for the first time to completing every jump.

In this process, Yao Aijun once again raised the level of control over his muscles, and this benefit was not only reflected in the action of 6245, but also improved the quality of all his other movements to a higher level!

That's why he did even more beautifully in the 109c later races! Because the least fancy action like 109c is the most basic skill, that smooth and delicate feeling is the effect that can only be brought about by the improvement of the overall level of the individual!

The 6245b jump of the Army Airlines started with a deviated jump, but ended with a beautiful finish.

In the diving arena, a scene of dynamic instability in the theoretical textbook is explained!

It is more powerful than the normal take-off, and the completion of the action is more smooth and clean than usual, and the whole set of movements seems to exude a natural atmosphere.

This "1-second action" that only lasted for a moment seemed to be invincible, and it should be so, telling everyone that this was not an accidental action, but an extremely stable result under a careful design!

Yes, it's the result!

is a no second possibility, the only outcome!

From Yao Aijun's center of gravity deviated from the jumping platform, such a perfect jump is the result! (To be continued.) )
