Chapter 1592: Flexural technology! Its better to use it with front side mechanics!
After three steps out.
Quick connection and acceleration run.
There are two aspects of acceleration running that mainly affect the connection and follow-up, mainly manifested in rapid and active force swing, followed by the impact on the body's center of gravity.
The swing is the blessing of the swing arm link. Su Shen has been doing well, and the swing arm in the acceleration zone is very fast.
This requires you to wait until the subsequent ability continues to recover before adjusting it.
The second is the technical movements of the lower body. If you want to exert more standard system capabilities in frontal mechanics, then in addition to the golden three steps, the forward angle of the torso must be done in place, and then the subsequent techniques must be made.
For example, flexing and pedaling technology.
This is the latest track and field achievement that is popular in the United States now. Of course, the Su Shen system has already arranged it, but if you want to achieve this technique, it is the same as starting with the floor... the athletes need to have strong physical strength.
If you can't do it, you will only run inappropriately.
Therefore, the threshold for real learning is not low.
The proposal of this technology was actually when the Soviet Union was about to collapse in the 1990s, Chuba and others in the former Soviet Union proved that when the knee joint stretched from 164° to 168° to 180° during the back pedal, the distance between the hip and ankle joint not only did not increase, but instead decreased by 8 mm. This is because when the tibial joint slides towards the femoral joint surface, the curvature increases, while the length and working distance of the legs do not increase, which is not conducive to the performance of speed.
Therefore, when the knee joint is within 164°, the angle of the knee joint is small, the distance between the hip joint and the ankle joint is small, and the radius of the forward swing of the legs is small, which is conducive to speeding up the forward swing. If the knee joint extends from 164° to 168° to 180°, additional work of muscles will inevitably occur. In order to reduce the inertia force of the forward swing of the thigh after pushing the ground and speed up the forward swing, there is no need to fully stretch the knee joint when pushing the back.
It’s just that theories have come out, and it’s just a theory. Why Randy and the others highly valued Su Shen? It’s mainly because Su Shen can not only propose theory, but how to apply theoretical things to the competition in combination with reality and transform them into special technologies. This is the real difficulty.
Generally speaking, a theory needs to be transformed from practical application to ten years or even longer. If you study it thoroughly and bloom more, it will take decades. This is what Su Shen feels like to be "terrifying" in scientific research.
Otherwise, just proposing various cutting-edge theories is just awesome, and it has not yet reached the God of Niu.
Doing so can quickly transform the theory, and this is the real awesome god.
Although the force rate of the hip flexor muscles is always greater than that of the rear pedal muscle group, this does not mean that the rear pedal muscle group and the rear pedal technology are no longer important. This technology is a typical example. At this stage, the rear pedal is only behind the hip flexor, and it is no longer the same as before the 1990s. As the dominant one, it is not just not important.
Especially the flexing and pedaling technology has the advantage that the flexural degree of the knee joint is increased, which prompts the movement amplitude of the hip joint to be greater than the movement amplitude of the knee joint, which makes the center of gravity move through the fulcrum relatively faster, and makes a certain gravity moment value match the reaction force generated by the maximum rear pedal, so that the technology of moving the body forward is more economical and effective.
Therefore, if you do a good job of flexing and pedaling, your center of gravity will be greatly controlled.
The second impact of acceleration running is quite consistent.
Therefore, after Su Shen reopened, because he wanted to use this body to rebuild the front side mechanics system, he must have to cooperate with the flex pedal-type technology of the rear pedal. After all, in the acceleration stage of the sprint start and the acceleration run after the start, the rear pedal power is one of the important factors in improving the running speed.
In order to achieve the entire future, Su Shen focused more on the strength rate of hip flexor muscles.
In fact, if you have to say this, you will suppress the rear pedal muscle group and even develop unbalancedly.
This time the rhythm has been completely rebuilt, and Su Shen must pursue as balance as possible after changing his feet.
Combining the force rate of the hip flexor muscle with the force rate of the back pedal muscle group.
Pair with an optimal value.
Instead of being the same as before, the force rate of the hip flexor muscle is placed in an absolute suppression position.
Of course, the most critical factor for him to do this is.
Although the flex-pitching technology is developing now and the United States is basically doing this, they do not understand that in fact, the flex-pitching technology is a key point in doing a good job in front-side mechanics.
If this point can be done well.
Your front mechanics will also be more perfect and perfect, and there will be fewer flaws and loopholes.
But now, not many people understand that the front mechanics was officially launched by Ralph Mann and Su Shen at the end of the year. Now the United States is still under research. If you want to combine it, even if Su Shen and his friends are in front of them, you have to think carefully about how many years will you get started.
Not to mention how to do front side mechanics, and match those technical counterweights to perform better.
All of these take time to experiment and collect data.
Unlike Su Shen, he knows exactly what to do and what direction to go.
Therefore, he never was confused or confused in his choice of these directions.
One of the reasonable indicators for measuring the 100-meter technology is to see whether its movement technology is effective, which is mainly reflected in whether it can "fast forward". The rear pedal stage is supported vertically from the body until the toes are pushed off the ground. Because the rear pedal leg produces a rear pedal force to accelerate movement. When the human body is running, the center of gravity is required to fluctuate small, and the forward horizontal component must be large.
The forward horizontal component is mainly determined by the back pedal force and the back pedal angle. Therefore, according to the mechanics of human body movement, it can be seen that the power of human body movement is caused by the contraction of the muscles of the back pedal legs to produce muscle tension and the ground to produce back pedal force. At the same time, the ground provides the support reaction force of the human body with the opposite direction in the same magnitude.
Then the advantage of the rear pedal angle of adopting the "flexive pedal" rear pedal technology is that... the forward inclination angle of the calf is smaller than that of the "traditional rear pedal" technology. The smaller the rear pedal angle, the horizontal component of the support reaction force generated by the contraction of the rear pedal leg muscle will naturally increase, which will also increase the horizontal displacement speed of the human body and reduce the fluctuation difference in the center of gravity of the falling step.
This chapter is not finished yet, please click on the next page to continue reading the exciting content later! In this way, you can be more "forward" by speeding up.
In this way, the running posture will naturally be more in line with the model requirements of front side mechanics.
Bang, bang, bang, bang, bang.
After Su Shen did this, he found that in the semi-finals, there was still some of Kakarara's golden three-step connection acceleration running, immediately...
Get smoother.
This unobstructed feeling made Randy feel like she was watching from the side...
Damn it.
I just asked something wrong and found a problem, but...
I haven't fully figured out how to solve it.
In the end, asking questions and solving them is not the same thing.
result……
Su Shen only needs to ask a question, and he, an athlete, can be responsible for solving it.
Solve various problems.
Solve various difficult and complicated diseases.
It seemed as if it was in his hands, it was all up and down, clean and crisp, without any delay.
This is this.
What kind of monster is this?
Randy was shocked by Su Shen's operation again. Only experts can understand how scary this is.
He, a science coach who believes that he is the world's leading science coach, even if he sees a problem, needs to spend a lot of time verifying it, proposing to solve the hypothesis, verify the hypothesis, and trial and error, and then he can give athletes a solution to the problem.
Especially for such athletes who are already at the peak of humanity, coaches need to be careful.
No sloppy at all.
Otherwise, coaches don’t like athletes to make technical changes easily.
Even Liu Xiang's mentor Sun Haiping was the one who opposed it at the beginning.
It is because the more advanced the athlete is, you have to help him change his technical skills. As a coach and team, the pressure will be high.
Even the pressure on this aspect will be greater, because generally speaking, athletes only need to execute the training plan formulated by the coach and the team, and do not need to be too brain-wrenching in this regard.
Since Colandi worked with Su Shen and since he arrived at Ersha Island, he seems to have never had such troubles.
No matter what questions you ask.
It seems that there will be people who will solve it quickly, and the answer given is almost perfect.
There is basically no need for trial and error.
Now it seems that the same is true for him. When Randy was still studying and scrutinizing the new front-side mechanics system, Su Shen was already quick and he found the optimal solution to the problem.
This made Randy feel that he had saved the coach's most troublesome link. Is it a bit embarrassed and a little hot to get so many beautiful knives?
But for Su Shen himself, it is...
Isn’t it just a foot change, and the front side mechanics are the problem that the connection between the start and acceleration is not good enough?
No big problem.
As long as you show me where the problem is, please help me ask where the problem is.
That's fine.
This money is worth spending.
After all, he is still alone. Many times he needs others to see the problem and think about the points he has not noticed.
Randy couldn't do this better.
Double salary is worth it.
There is absolutely no intention of Randy being passive and taking advantage of it.
Without a master coach like Randy, helping me keep changing the game model and studying video problems, even if I can discover it, it will take a lot of extra time, which is not worth the effort.
But I just didn't do well in the semi-finals and preliminaries, or I lacked a link.
Since Randy proposed it last night.
Then I have to adjust it for him and find a way to solve it.
This will allow Randy to continue to discover other new problems and continue to solve them.
After all, the London Olympics are just this year, and he doesn't have time to drag it.
Now he.
I'm also in a hurry.
But there is no time to waste.
Bang, bang, bang, bang, bang.
Su Shen’s few moves.
Immediately, I quickly rushed up from the position.
He was immediately with Liangta, Kuangshishan County, Jianglikou, who was still in a clear lead.
Run side by side.
No.
Look at this posture.
I'm afraid it will be over immediately.
"Su Shen's activation is slightly behind, but...it's very fast!?"
"Soon Su will adjust and catch up!"
"Even...completed the overtake!!!"
On the field, Kuangshi, Jianglikou next to Su Shen, was a little shocked by Su Shen.
It is obvious that you are running very badly here in the preliminaries and semi-finals.
Why is it so good all of a sudden?
Is the connection so smooth?
You said you just adjusted it overnight?
Why don’t I believe this?!
I see……
Teacher Su.
That's why you want me to do my best before the game.
Actually you...
It has recovered a lot, so I have been hiding my weaknesses in front of me.
I.
I understand!
Su Shen:...
If he knew what Jianglikou Kuangshi was thinking, he would definitely complain:
I really adjusted this that night and it was still very warm.
