Chapter 186 The concept of time and space! The most important technical system for sprinting
Su Shen touched his butt. It may be far different from before the reopening, but it can still be regarded as a "small butt".
Although the maximum weight is not done, the sub-maximum weight is used to increase height, and it is also used to increase muscle, strength and explosion.
So.
Some things will also start to be put on the agenda.
For example, the actual use of the buttocks, how to use the buttocks to increase the strength and intensity of the hip delivery technique.
Current thinking places too much emphasis on using only leg muscles to lift the hips. Well, actually, this is still a big deal.
Because the fact is...our country currently does not have a truly scientific and systematic "hip transplantation technology".
They are still pieced together here and there, or some "private secrets" that the coach himself has learned, and provide "passing on" type of teaching.
Such behavior will cause a large information bias.
In severe cases, it may even leave some people with huge potential injuries.
For example, Zhao Haohuan is a typical example.
Although the coach initially asked him to practice the "hip sending technique", it is definitely a good thing with advanced concepts.
However, Zhao Haohuan's hip mobility and flexibility issues were not taken into consideration.
Coupled with the "three from one" principle of being strict, being difficult, starting from actual combat and exercising a lot, not only did Zhao Haohuan not improve, but the more he practiced, the more mistakes he made. In the end, his performance declined, he was plagued by injuries, and he retired early.
Su Shen wants to make it very clear here. "Hip transplantation technology" is definitely an advanced technical concept, but how to "transfer" it and how to "transfer it" scientifically is a scientific issue.
Fortunately, this is not a difficult matter for Su Shen.
He has mastered the best method, and it is naturally much easier to work backwards from the results.
Not to mention, he himself is a professional researcher and the "head" of Sushen Dash Laboratory.
Su Shen has decided to fine-tune his technique during the winter training period.
After the reopening, the time here was too tight, and there were too many goals and competitions to prepare for. As a result, this large technical system could only be put on hold for the time being, and the most urgent parts were done first.
Now that the National Games is over, winter training is about to begin, which will take a long time.
Some of the longest professional winter training courses even last for several months or even a hundred days.
Therefore, Su Shen finally had time to polish other technical details.
for example.
There are several major problems with the basic "hip delivery" of our country's sprinters -
The front pedal distance is too close.
The supporting legs have poor cushioning.
The front pedal angle is too large.
After Su Shen told everyone about this problem, everyone was "shocked" again.
Here it comes again and again.
Su Shen’s “Small Classroom” has started again.
Although everyone has gradually become accustomed to it, Su Shen discovered new knowledge and new arguments in books, papers, and journals at every turn, but... you can use it right away. This is too scary for you.
Even a fool knows that this is not something ordinary people can do.
Can you "create inventions" just by reading books and information? If it were so easy, human beings would have advanced in all walks of life for a thousand years.
so.
between.
Is this the brain of a genius?
Some of the good friends below have the urge to open Su Shen’s head and take a closer look.
…
"So many questions?" Zhou Bing asked doubtfully, "Does it mean that Gou Huan is as strong as him?"
"Of course." Su Shen nodded and said, "If he can do this well, his strength will make a big leap forward."
"Same for you."
Ningdebao recorded these problems, opened his mouth and asked: "Then Xiaotian, how should we solve it?"
"First of all, everyone knows where the hip is." Su Shen saw everyone nodding and was very pleased. Because there are too many athletes in the country, if you tell him about these places, they won't even know where they are.
In that case, how can we make precise and rapid improvements?
"The hip is the part where the trunk and the legs are connected. It allows your trunk and legs to move forward, backward and sideways independently. So what are the specific parts of this part?" Ningdebao found out, and Su Shen seemed to go smoothly.
Being able to step into this role of "teacher" is as if he is more skilled than her, as if he has been a teacher before.
This feels weird.
Can't tell exactly why.
But it really gave Ningdebao such an "illusion".
It can only be understood that Su Shen may be born to "teach and educate people" and impart this professional knowledge.
If he is not an athlete, maybe he would be good as a "teacher".
…
"I know, Brother Tim, the hip is composed of the lumbar spine, sacrum, ilium, gluteus maximus, piriformis, rectus abdominis, etc. It is a collective term composed of many parts." Chen Juan replied, seemingly
She has already memorized this knowledge by heart.
"Okay, let's take a look at the hip joint." Su Shen took out the diagram he had drawn long ago, hung it on the wall, and said: "The hip joint is composed of the femoral head and the acetabulum. It is a ball and socket joint. It is a typical
The femoral joint surface occupies 2/3 of the head area and is embedded in the acetabulum. The lunate surface of the acetabulum surrounds the acetabular fossa, which is filled with fat, and the acetabular labrum is attached to the acetabular rim to increase the depth of the acetabulum."
"It has three axes, namely the coronal axis, the sagittal axis, and the vertical axis. The thigh can produce flexion, extension, adduction, abduction, and circular motion at the hip joint. Since the hip joint has to bear the weight, it must also remain standing.
, walking, jumping, running, and a series of sports actions, so it has four ligaments to stabilize it. They are the hip ligament, the pubic ligament, the ischial ligament, and the femoral head ligament." Su Shen glanced at Zhao Haohuan and said: "
Because of this, the joint capsule of the hip joint is thick and tight, which actually hinders the body's range of motion and motor function. Therefore, when training, we must pay attention to the flexibility and flexibility of the hip joint, etc."
"Similar to Gou Huan's previous problem, the problem is that his hip joints are naturally tight. Without flexibility training and more hip opening training, it will only cause more and more side effects."
Zhao Haohuan watched carefully.
After all, this injury has tortured him a lot.
It was even almost scrapped.
"Then why does our country's hip transplantation technology have these big problems?" Su Shen took out another written piece of paper, sucked it on the wall, and said, "Because our ideas are too scattered."
"These are the five mainstream hip transplant techniques in China that I have summarized. You can take a look and see what the differences are."
Zhao Haohuan and others took a closer look, and saw five big dots written on the white paper——
1. The theory of triaxial movement of the pelvis.
2. Swing your legs and bring your hips together.
3. Pushing on the ground and sending your hips forward.
4. Central axis motion theory.
5. The pelvis is forward.
Each one also comes with detailed explanation and analysis.
This really makes everyone admire and feel that the gap between people is so big...
I thought it was there before, but it's not so obvious yet.
The more I get in touch now, the more I realize... people are really different from each other.
Even Ningdebao.
If I hadn't seen it in advance, I would probably have the same expression as them now.
…
"Mine is this kind, so that's it, it turns out that I have this kind of hip-transfer technique." Zhao Haohuan quickly found his own kind in it, and his own coach couldn't tell the specific name and reason.
"Send hip technology".
"But in fact, I think these methods all have merits and shortcomings. This is the disadvantage of no system and chaotic teaching at the moment." Su Shen said: "If we can focus on these things earlier, maybe we can
Enter a new stage early.”
This is a fact. Japan can produce results so quickly because everything is studied together by the whole country.
For example, in the case of our hybrid rice, if Grandpa Yuan hadn't taken the initiative to release the technology and let professionals from all over the country study it together, he himself said he didn't know how many more years it would have been used.
Running technique is naturally similar.
If we cannot integrate them, even though we have never lacked smart people, we still have no power to use them all at the same time.
Fortunately, it has reopened now.
It is easy to integrate them, take the essence and discard the dross, and combine them with scientific theories.
…
"Then let's look for what these five domestic mainstream theories have in common." Su Shendao: "That is the hip delivery technique in sprinting, which includes 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 filled with various graphics, sucked it on the front again, and said: "Add an object without any constraints, you can interact with it.
Translating and rotating on three axes, it has six degrees of freedom of motion. The free object at the other end only has three degrees of freedom of motion, so what happens?"
Su Shen entered "Professor Su Mode" and began to take the initiative to ask questions.
The result is naturally that the person below is confused and doesn't know what to say.
"Didn't you understand? Didn't I explain it carefully enough?" Su Shen was a little confused, but he soon realized...
These people are not the graduate students who were later brought up by themselves.
These people are still underage children.
And this time point is in 2005... You said this, let alone a minor, even if the industry leader took it, he would probably have an expression of "I haven't given up on learning yet".
"It's okay. This may be a bit complicated for you now, so I'll make it simpler." Su Shen said naturally, but the people listening didn't think so.
They all began to have a further sense of "admiration" for Su Shen's head.
This will be true "worship".
Humanity's most primitive worship and reverence for knowledge.
"...In other words, it is impossible to produce translational motion. It can only rotate around the three coordinate axes."
"...When the hip joint formed by the acetabulum and femoral head serves as the relative fixed point of the pelvis, the pelvic motion has only three degrees of freedom."
"So, do you all know what the real hip transplantation technique is?" Su Shen asked, looking at everyone.
The people below were all shaking their little heads as fast as a rattle.
"To put it simply, the hip delivery technique refers to the movement process in which the human pelvis actively rotates around the parallel axis of the body under the control of the central nervous system during running. This movement runs through every movement in running.
Each action stage of the cycle, and the performance in each action stage is different." After Su Shen finished speaking, he looked at everyone and said, "You understand this time."
Understand? You understand what you understand?
Teacher Su, we don’t understand.
Especially at this time, Su Shen added: "By the way, this is just a rough description. If the professional is more scientific, it should be explained from the three aspects of anatomy, kinematics, and biomechanics."
Everyone:......
At this point in the class, even Ningdebao, a female college student majoring in the class, is a little overwhelmed.
Although Su Shen made it so simple, in fact Ningdebao's own feeling is that "this lesson" includes the extraction of information, the screening of information, the integration of information, the elimination of false information and the preservation of true information, and the commonality of information.
Finally, there is the secondary creation of information or personal research to derive new information.
Being able to do all the steps was simply terrifying in the 2005 era when the Internet was still underdeveloped.
I don’t know if Fighting to the Sky is currently being serialized, otherwise I could really use one sentence——
This boy is so terrifying.
Just talking about these five points, how many people in China can integrate them so comprehensively? Put them clearly in front of you and analyze them one by one.
monster.
This guy is a monster.
From this aspect, Ningdebao felt that Su Shen's brain was probably even more exaggerated than his sprinting talent.
He alone can now outperform half of the professionals in the country.
or.
He is everything.
Thinking of this, Ningdebao finally understood how some history books described the "unparalleled monsters" of that year in that way.
I thought it was exaggerated before.
That's entirely because I haven't seen such a person before.
This chapter is not over yet, please click on the next page to continue reading the exciting content! When such a person is in front of you.
Only then did she realize how big the gap was.
She even doubted for a moment...that the speed of knowledge absorption by people like her was not as fast as the "creation" speed of other people's knowledge.
Someone once said that the gap between people is sometimes greater than that between people and dogs.
Now she feels it deeply.
Indeed, it is not on the same level.
Fortunately, she has been in contact with Su Shen for so long, and she has gradually gained some immunity to some "out of line" things.
Otherwise, I really won’t be able to close my mouth.
Su Shen was still talking above:
"...These are some of the benefits of hip delivery technology. We can split it into a system, so there is no need to run in individual projects separately."
"...Correct hip delivery technique can easily change the stride frequency, stride length, kickback, coordination, and...the acceleration and explosive power of the first three to five."
Especially the latter argument was discovered almost after 2015.
The real push time in China is July 2017.
This is also the thing that Su Shen brought into "Super Time and Space", and it is deeply hidden among the technologies that everyone can see now.
"Going back to the three domestic hip problems at the beginning, the front pedaling distance is too close, the supporting leg has poor cushioning, and the front pedaling angle is too large." Su Shen said patiently and meticulously: "The traditional view emphasizes the development of the knee extensor muscles.
.The latest view now emphasizes the strength of the hip, hamstring and calf muscles, as well as the development of hip strength.”
Especially the addition of the buttocks, this concept will not be launched until 2020, and it is considered one of the top researches.
Su Shen joined here in advance so that everyone can receive targeted reinforcement and training more than ten years earlier than others.
Because the "hip sending technique" is one of the core techniques of sprinting, it requires adjustment and modification and will accompany you throughout your sports career.
Therefore, this technique is not as simple as the "six-second rule", "crank-arm start" and "full-hand arm swing". It involves too many things and requires the entire winter training. Normally, there is no such time and energy.
.
After Su Shen finished this "small class", everyone breathed a sigh of relief.
There are too many things crammed into it.
When Zhou Bing heard this, he felt like his head was buzzing.
Even Zhao Haohuan, who has always had outstanding sprint comprehension ability, is looking at these things with his eyes in a daze.
I feel a little "skeptical about life".
However, Su Shen did not intend to let them understand it all at once. After all, the "hip technique" is a technical system that affects the whole body.
Just set a correct direction for them first, and then start working hard.
This will not disappoint those domestic pioneers who took one step early and were the first to see the problem.
"Okay, everyone, relax, let's start training the gluteus maximus muscles." Su Shen stood up. He hadn't felt it before. After hearing Su Shen emphasize the role of the gluteus maximus muscles, everyone now looked at it.
Holding Su Shen's ass, he thought to himself——
Never discovered it before.
His ass is so shapely.
Everyone couldn't help but touch their butts again, and suddenly looked frustrated——
It's flat and small.
PS: The big chapter has arrived, and I still owe the leader five chapters, so pay it off as soon as possible~~~
So Su Shen asked: Has everyone learned today’s little knowledge? (*^▽^*)~~~
