Chapter 1592: Kneeling technique! Combined with front side mechanics, its even better!
After taking three steps out.
Quickly connect and accelerate running.
There are two aspects of accelerating running that mainly affect the connection and follow-up. The main manifestation is the rapid and active active force swing, and the second is the impact on the center of gravity of the body.
The swing is the blessing of the arm swing link. Su Shen has always done a good job, and the circular arm swing in the acceleration zone enters very quickly.
This will have to be adjusted after subsequent abilities continue to recover.
The second is the technical movements of the lower body. If you want to use more of the standard system capabilities of front side mechanics, in addition to doing the golden three steps, the forward tilt of the trunk must be in place, and then the subsequent techniques must be developed.
For example, the kneeling technique.
This is the latest track and field achievement that is relatively popular in the United States. Of course, the Su Shen system has already arranged it, but if you want to achieve this technique and start from scratch... you need the athletes to have strong physical strength.
If you can't do that, you'll just run around in a nondescript manner.
So the threshold for truly learning well is not low.
This technology was actually proposed in the 1990s when the Soviet Union was about to disintegrate. Chuba and others from the former Soviet Union conducted research and proved that when back pedaling, the knee joint extended from 164° to 168° to 180°, but the distance between the hip joint and the ankle joint did not increase.
, but decreased by 8 mm. This is because when the tibial joint slides against the femoral joint surface, the curvature increases, but the length and working distance of the leg do not increase, which is not conducive to the development of speed.
Therefore, when the knee joint is within 164°, the knee joint angle is small, the distance between the hip joint and the ankle joint is small, and the radius of the leg swinging forward is small, which is conducive to speeding up the forward swing. If the knee joint is from 164°
° ~ 168° extending to 180°, there will inevitably be additional work of the muscles. In order to reduce the inertial force of the thigh swinging forward after pedaling and speed up the forward swing, it is not necessary to fully extend the knee joint when pedaling backward.
It's just a theory, and it's just a theory. Why Randy and the others admire Su Shen so much? The main reason is that Su Shen can not only put forward theories, but also how to combine theoretical things with practical applications into competitions and transform them into special technologies.
This is the real difficulty.
Generally speaking, it takes ten years or more for a theory to be put into practical application. If the research is thorough and more fruitful, it will take even more decades. This is what Su Shen thinks is "scary" in terms of scientific research.
Otherwise, just proposing various cutting-edge theories is still just awesome and has not yet reached the level of awesomeness.
In this way, the theory can be quickly transformed, which is the real brilliance above the brilliance.
Although the force generation rate of the hip flexor muscles is always greater than that of the back-pedaling muscles in the entire 100 meters, this does not mean that the retro-pedaling muscles and back-pedaling technology are not important now. This technology is a typical example. At this stage, it is only the back-pedaling muscle group.
Ranked behind hip flexion, it is no longer as dominant as it was before the 1990s, but it is not unimportant.
In particular, the advantage of the bent-pedal technique is that the flexion of the knee joint of the kicked-off leg is increased, which promotes the range of motion of the hip joint to be greater than the range of motion of the knee joint, makes the center of gravity move through the fulcrum relatively faster, and makes a certain gravity moment value
Matching the reaction force generated by the maximum back pedaling, the technology of moving the body forward is more economical and effective.
Therefore, if the bending technique is done well, your center of gravity will be greatly controlled.
Regarding the second impact of accelerating running, it is quite consistent.
Therefore, after Su Shen restarts, because he wants to re-use this body to build the front side mechanical system, he must cooperate with the back pedaling technique of the bending pedaling technique. After all, during the sprint start and the acceleration stage after the start, the back pedaling strength is to improve
One of the important factors of running speed.
In the past, Su Shen paid more attention to the force generation rate of the hip flexor muscles in order to perform well in the future.
This kind of continuous growth actually suppresses the rear pedal muscles and even leads to uneven development.
This time the rhythm has been completely re-created. After changing feet, Su Shen must pursue as much balance as possible.
Combine the force generation rate of the hip flexor muscles with the force generation rate of the kickback muscle group.
Match an optimal value.
It is no longer the same as before, that is, the force exertion rate of the hip flexor muscles is ranked in an absolutely suppressed position.
Of course, the most critical factor for him to do this is...
Although the pedaling technology is also developing now, and the United States is basically doing it, but they don't understand that actually doing the pedaling technology is a key point for doing good front side mechanics.
If this can be done well.
Your front side mechanics will also be more complete and perfect, and there will be fewer flaws and loopholes.
It’s just that not many people understand it now. After all, frontal mechanics was only officially published in a book by Ralph Mann and Su Shen at the end of the year. It is still being studied in the United States. If they want to combine it, even if Su
Even though they are very good at it, they still have to think hard for several years before they can get started.
Not to mention how to do the front side mechanics and match those technical weights to perform better.
These all take time to do experiments and collect data.
Unlike Su Shen, who knows exactly what to do and what direction to take.
Therefore, he was never confused or confused in choosing these directions.
One of the reasonable indicators to measure the 100-meter technique is to see whether the movement technique is effective, and the most important manifestation is whether it can "forward quickly". The back kicking stage is from the vertical support of the body until the toes kick off the ground. Because
The back kicking of the legs produces back kicking force to accelerate the movement. When the human body is running, the fluctuation of the center of gravity is required to be small and the forward horizontal component to be large.
The forward horizontal component is mainly determined by the force of the back kick and the angle of the back kick. Therefore, according to the mechanical principles of human movement, the power of human movement is the muscle tension generated by the contraction of the back kick leg and the back push force generated by the ground. At the same time,
The ground provides equal and opposite supporting reaction forces to the human body.
Then the advantage of using the back-pedaling angle of the "flexing-pedaling" back-pedaling technique is...the forward inclination angle of the calf is smaller than that of the "traditional back-pedaling" technique. The smaller the back-pedaling angle, the more support reaction produced by the contraction of the back-pedaling leg muscles.
The horizontal component of the force will naturally increase, which will also increase the horizontal displacement speed of the human body and reduce the fluctuation difference of the falling center of gravity.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! In this way, you can become more "forward" by speeding up your running.
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 a good job in this aspect, as expected, he had some of Carkarala's golden three-step acceleration just in the semi-finals, and immediately...
Get smoother.
This smooth feeling made Randy feel...
Damn it.
I just mentioned something wrong and found a problem, but...
I haven't fully figured out how to solve it yet.
After all, raising problems and solving problems are completely different things.
result……
Su Shen only needs you to raise a problem, and he himself can be responsible for solving it as an athlete.
Solve various problems.
Solve various difficult and complicated diseases.
It seems that when it comes to his hands, the knife is lifted and dropped, clean and crisp, without any sloppiness.
This, this, this.
What kind of monster is this?
Randy was once again shocked by Su Shen's operation. Only an expert can understand how scary this is.
As a scientific coach who considers himself to be the world's leading, even if he sees a problem, he needs to spend a lot of time to verify it, come up with solutions, verify the hypotheses, and go through trial and error before he can give the athletes a solution to the problem.
Especially this kind of athlete who is already at the pinnacle of humankind needs coaches to be cautious.
There's nothing careless about it.
Otherwise, coaches don’t like athletes to make technical changes easily.
Even Liu Xiang's mentor Sun Haiping was opposed to it at first.
This is because the more advanced an athlete is, the more you have to help him make technical changes. As a coach and a team, the pressure will be greater at the same time.
There will even be greater pressure in this aspect, because generally speaking, athletes only need to implement the training plan formulated by the coach and team, and there is no need to worry too much about this aspect.
But ever since Randy cooperated with Su Shen and since he came to Ersha Island, he seems to have never had such troubles at all.
No matter what questions you ask.
There seems to be someone who can solve the problem quickly, and the answer given is almost perfect.
Basically there is no need for trial and error.
Now, it seems to be the same in his own case. When Randy was still researching and deliberating on this problem when faced with the new front side mechanics system, Su Shen had already quickly found the optimal solution to the problem by himself.
This made Randy feel for a moment that he had avoided the most troublesome part of the coach's life. It was a little embarrassing and a little hot to handle so many beautiful knives.
But for Su Shen himself...
Isn't it just a problem that after changing the foot and switching to front-side mechanics, the connection between startup and acceleration is not good enough.
Not a big problem.
As long as you show me where the problem is, help me figure out where the problem is.
That's OK.
It's money well spent.
After all, he is still a person, and many times he needs others to see problems and think about points that he has not noticed.
Randy couldn't have done this any better.
Double salary is worth it.
I definitely didn’t feel that Randy was slacking off or taking advantage.
Without a master coach like Randy to keep an eye on him, help him constantly modify the game model, and study the video problems, even if he could find them, he would still have to spend a lot of extra time, which would be more than worth the gain.
But what I didn't do well in the semi-finals and preliminaries just now may be a missing link.
Since Randy brought it up last night.
Then you have to adjust it yourself and find a way to solve it.
Only in this way can Randy continue to discover other new problems and continue to solve them.
After all, the London Olympics was just this year, and he didn't have time to delay it.
Now he.
I'm also in a hurry.
But there's no time to waste.
Bang, bang, bang, bang, bang.
Su Shen, these few times.
He immediately rushed up from his fallen position.
All of a sudden, he and Liang Tai from Jiangliguang Kuangshishan County, who had just started and were still in the clear lead.
Let's keep pace.
No.
Look at this posture.
I'm afraid it will be exceeded soon.
"Su Shen is a little behind in starting, but... it's very fast!?"
"Su Shen will adjust and catch up soon!"
"Even... completed the overtake!!!"
On the playing field, Masashi Erikuchi, who was next to Su Shen, was a little stunned by Su Shen's move.
Obviously you did not perform well here in the preliminaries and semi-finals.
Why did it feel so good all of a sudden?
Is the connection so smooth?
You said you adjusted it in one night?
Why don’t I believe this?!
I see……
Teacher Su.
This is why you want me to go all out to fuck you before the game.
Actually you……
I've recovered quite a bit, so I'll keep hiding my weakness in the front.
I.
understood!
Su Shen:......
If he knew what Masashi Erikochi was thinking, he would definitely complain:
I really adjusted this that night, and it was still warm.
It really is...
What you think is impossible means.
