Su Shen touched his butt, perhaps far from being before reopening, but at least he was a "little butt".

Although the limit is not used to increase the weight, the sub-limit is used to increase the height, and is also used to increase muscle and strength and increase the explosion.

So.

Some things are also going to be put on the agenda.

For example, when it comes to the real use of the buttocks, how to use the buttocks to increase the strength and strength of the hip-sending technique.

Nowadays, I emphasize using only leg muscles to send hips. Well, this is actually a big deal.

Because the fact is... my country now has no truly scientific and systematic "hip delivery technology".

They are all just pieced together, or some "private secrets" that the coach has learned by himself, and teaches "transmitting skills" type.

Such behavior will cause great information deviation.

If it is serious, it will even leave some people with huge potential for injury.

For example, Zhao Haohuan is a typical example.

Although the coach asked him to practice "hip delivery technique" at the beginning, it was definitely a good thing with advanced concepts.

But Zhao Haohuan's hip joint mobility and flexibility were not taken into account.

In addition, strictness, difficulty, and actual combat. The principle of "three after one big" in large exercise will not only not improve Zhao Haohuan, but the more he practices, the more he has problems, and in the end, his grades have declined, and he is suffering from injuries, and he retires early.

Su Shen has to make it clear here. "Hip-delivery technology" is definitely an advanced technical concept, but how to "delivery" and how to "delivery" scientifically is a scientific issue.

Fortunately, this is not a very difficult thing for Su Shen.

He has mastered the best way, and it is naturally much easier to turn it back from the results.

Not to mention, he himself is a professional researcher and the "head of Sushen Sprint Laboratory.

Su Shen has decided to adjust his technology during the winter training period.

After the reopening, the time was too tight, and there were too many goals and competitions to prepare for, which resulted in the large technical system being able to be temporarily stranded and the most urgent part was temporarily done.

Now that the National Games are over, the winter training is about to begin, and there will be a long time.

Some of the longest professional winter training can last for several months or even one hundred days.

So, Su Shen finally had time to polish other technical details.

for example.

Several major problems of "hip delivery" for Chinese sprinters now-

The front pedal distance is close.

Support legs give way to buffer.

The front pedal angle is too large.

After Su Shen talked about this issue to everyone, everyone was "shocked" again.

It's coming again.

Su Shen’s “small classroom” is starting again.

Although everyone has gradually gotten used to it, Su Shen often discovers new knowledge and new arguments in books, papers, journals, but... you can use it immediately, you are so scary.

Even fools know that this is not something that ordinary people can do.

Can you "create and invent" just by reading books and materials? It's so easy. Human beings have been moving forward for a thousand years in all walks of life.

so.

between.

Is this the brain of a genius?

Some of the good friends below all had the urge to open Su Shen’s head and take a closer look.

...

"Do you have so many questions?" Zhou Bing said in confusion: "Is Gou Huan so strong, too?"

"Of course." Su Shen nodded and said, "If he can do this well, his strength can also make a big leap."

"Same for you."

Ning Debao recorded these problems and opened his mouth and asked, "Why should Xiaotian solve it?"

"First of all, everyone knows where the hips are." Su Shen nodded and was very pleased when he saw everyone. Because there are too many athletes in China, people can't even figure out where they are when you tell him about these places.

In that case, how can we make accurate and rapid improvements and improvements?

"The hip is the part connecting the torso and legs, which can enable your torso and legs to move forward, back and side by side independently. So what specific parts are there?" Ning Debao discovered that Su Shen seemed to be able to enter this role of "teacher" smoothly, as if he was more skilled than her, as if he had been a teacher before.

This feels strange.

I can't say why.

But it really gave Ning Debao such an "illusion".

It can only be understood that Su Shen may be born to be suitable for "teaching and educating people" and imparting knowledge in this professional field.

If he doesn't become an athlete, maybe he's not good enough to be a "teacher".

...

"I know, Brother Tian, ​​the hip is composed of lumbar spine, sacrum, iliac bone, gluteus maximus, piriformis, rectus abdominis, etc., and is a collective name composed of many parts." Chen Juan replied, and it seems that she had already memorized these knowledge.

"Okay, then we're looking at the hip joint." Su Shen took out the picture he had drawn long ago and sucked it on the wall, saying: "The hip joint is composed of the femoral head and acetabulum, belonging to the ball joint, and is a typical pestle and mortar joint. The femoral joint surface accounts for 2/3 of the head area and is embedded in the acetabulum. The lunar surface of the mortar surrounds the acetabulum fossa, which is filled with fat, and the acetabulum lip attaches to the edge of the mortar to increase the depth of the mortar."

"It has three axes, namely the coronal axis, the sagittal axis, and the vertical axis. The thighs can produce flexion, extension, adduction, abduction, and annular movements at the hip joints. Since the hip joint needs to bear weight and maintain a series of movements such as standing, walking, jumping, running, etc., it has four more tenacities that bring stability. They are hip ligament, pubic ligament, sciatic ligament, and femoral head ligament." Su Shen looked at Zhao Haohuan and said, "Because of this, the joint capsule of the hip joint is thick and tight, which actually has an hindering effect on the body's movement amplitude and motor function. Therefore, when we are training, we must pay attention to the flexibility and flexibility of the hip joints, etc."

"Similar to the previous problem of Gou Huan, it's here that his hip joint is born tighter. Without flexibility training and more hip opening training, it will only cause more and more side effects."

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! Zhao Haohuan looked at it carefully.

After all, this injury has tortured him a lot.

It was almost ruined.

"So why does my country's hip-sending technology have the above major problems?" Su Shen took out another written paper and sucked it on the wall, saying, "Because our philosophy is too scattered."

"These are five mainstream hip-sending technologies in China that I have summarized. You can see what the difference is."

Zhao Haohuan and others approached and looked at it. Five big dots were written on the white paper.

1. The theory of triaxial movement of the pelvis.

2. Swing your legs and hips.

3. Tap the ground and send the hips to say.

4. Central axis motion theory.

5. Pelvic front talk.

Each also comes with detailed explanations and analysis.

This really makes everyone admire and feel that the gap between people is so big.

I thought there was, but it wasn't that obvious yet.

Now the more you come into contact with each other, the more you realize... people are really different.

Even Ning Debao.

If I hadn't seen it in advance, I would probably have the same expression as them now.

...

"Mine is this, so that's it. It turns out that I have such a hip-sending technique." Zhao Haohuan quickly found his own "hip-sending technique" in it, and his coach could not tell the specific name and reason.

"But I think these methods are both desirable and deficient. This is the disadvantage of the lack of system and chaotic teaching at the moment." Su Shen said: "If we could concentrate these things together to study them early, we might also enter a new stage early."

This is a fact. It is because Japan can produce results so quickly because the whole country is working together to study the world.

For example, if Grandpa Yuan hadn’t taken the initiative to release the technology and let professionals across the country study it, he himself said he wouldn’t know how many years would be used.

The running technique is naturally similar.

If we cannot integrate, even if we never lack smart people, we still have strength and cannot use it in one place.

Fortunately, I reopened it myself now.

It is easy to integrate it, take the essence and remove the dross, and combine it with scientific theories.

...

"Then let's find the common points of these five mainstream domestic theories." Su Shen said: "That is the hip-sending technique in sprinting, which contains the rotation of the pelvis during running."

"Let's take a look at the detailed motion analysis diagram." Su Shen took out another piece of paper covered with various figures, sucked it in front again, and said: "Add an object is not subject to any constraints. It can be translated and rotated relative to the three axis, and has six degrees of freedom of movement. The free object is on the other end and has only three degrees of freedom of movement. So what happens?"

Su Shen entered the "Professor Su mode" and began to ask questions on his own initiative.

The result was naturally that the lower body was confused and didn't know what to say.

"Didn't you understand? Did I not explain it carefully enough?" Su Shen was a little confused, but soon he realized...
