Chapter 1629 His eyes are beacons! A new era is about to begin!
Randy never thought that he would actually need to know Chinese before he knew the technical words in English.
This has never happened before in his teaching career.
This is also a novel experience.
"Semi-folding technology?" Randy thought for a while: "What exactly is it?"
"Many people in China want to fold too actively, which will cause the calves to turn too fast to increase the cadence, but there are many such problems." Su Shen replied patiently: "Then when you are flying in the air
In terms of time, there will be problems.”
"Not folding???" Randy was confused for a moment. The joke was about to get bigger now. This was no less than the previous theory of bombing. After all, the whole world is vigorously promoting folding. This
Didn't you say you want to challenge the whole world?
"No, no, no." Su Shen immediately shook his head and said, "That's not it. It's not that it doesn't fold. Our laboratory has recently proven a problem, that is, if you want the foot on the ground to reach the ground quickly, the other foot cannot be too hooked.
stand up."
"Then how to get there?" Randy asked in astonishment.
"Go from this place." Su Shen used his body as an analogy, passing his hand closer to the bottom of his knee, and said: "Then stretch the other leg up, otherwise your speed will slow down."
"this……"
"But how to get there?" Randy still couldn't figure it out, and Su Shen started to put forward another concept at this time.
"Low Heel Recovery."
"Low-heel recovery???" Randy said in astonishment: "What new term is this? What is its English name?"
When I'm with Su Shen, I really feel like I'm hearing new things every day. The difficulty of innovation seems to be non-existent with him.
"Temporarily called Low-Hell-Recovery."
"Low-Hell-Recovery?" Randy repeated, feeling that he had learned a lot of new terms today.
The amount of information is a bit large.
"That's it." Su Shen added a line to his running on the computer. This line was not high and was lower than his knees.
Then let Randy read it.
After reading it several times, Su Shen asked: "Did you see anything?"
"This..." Randy looked at it carefully a few times. After thinking about it, he frowned and said, "It seems to be running in the air..."
"Your ankle never crossed this line?"
"That's right." Su Shen snapped his fingers. As expected of Randy, he understood these details easily.
"That is, the angle that will occur when the ankle of the back leg crosses the knee of the front leg. Currently, 82 to 87 degrees is an ideal state, and relative to an individual, bigger is better, and the bigger the better.
Close to the ground, the explosion and operation will be better. Of course, it must be matched with other technical details. All technologies are for actual service, otherwise it will be meaningless."
Randy looked at the computer, thought for a moment, and seemed to suddenly think of something. He looked at Su Shen and suddenly said: "No, it's not, you guys..."
"Have you solved the biggest problem by keeping silent?"
The reason why Randy is like this is because in the process of switching from rear side technology to front side technology (note that technology is not mechanics), there is a system problem that is difficult to solve, that is, the front and rear side technology is actually in the running process.
, in fact, it has always existed.
There is no pure front technology or pure rear technology.
It just depends on the two ratios.
If someone says that he only has front-side skills and no back-side skills, he must be an outsider and is trying to fool you into not knowing his skills.
In fact, an excellent athlete will have both front and rear skills when running. This is the normal running line.
Otherwise, only the front side will fall, and only the back side will bite.
So here comes the question. The reason why Randy is so stunned, even more stunned than before, is mainly due to the front and rear side technologies. So far, there is no particularly good solution to truly integrate and match. Moreover, the technical concepts of the front and rear sides belong to
It’s such a novel thing, but many people haven’t figured it out yet after researching it. Why do you still ask them to match it?
That is simply a difficult task for a strong person, even more difficult than asking a sumo wrestler to run a marathon.
What Su Shen meant by this was that he had discovered one of the nodes connecting the two technologies.
"The straight line distance between two points is the shortest. I believe everyone knows this, so how to reduce the swing time?" Su Shen tapped the English words on the whiteboard with his hand and said with a smile: "This is one of the answers to the puzzle."
"If it can be done well."
"Then the process of switching from back-side technique back to front-side technique, and from back-side technique back to front-side technique...the swing time will be greatly reduced and reduced."
"In this way, the mutual use of rear-side technology and front-side technology will be more smooth and smooth, and the proportions will be more harmonious. Moreover... this can also better match the front-side mechanics and combine the front-side mechanics.
The advantages can be further exploited and developed.”
"Then..." Randy looked at the smiling Su Shen, opened his mouth and said a few words, then held back a few words before asking the last question: "Where is the key point? Have you found it?"
If you don’t know the key points, you’ll still be stuck in theory and won’t be able to put it into practice right away.
That may have great significance for the future, but it doesn't mean much for the present.
Especially now that everyone is preparing for the Olympics, there really is no time to waste.
"Yes, I found it." Su Shen nodded and said, "TD and COG."
"What, what do you mean?" Randy really felt that his brain was a little exhausted today. He kept saying "what do you mean" every time. He even thought it was a bit funny. He had never seen such a situation in all his years of coaching.
It totally feels like being a primary school student.
However, he is also very thirsty for knowledge. When he sees something new, he never fails to ask for an explanation.
After all, he has devoted his whole life to track and field and has not even gotten married.
This chapter is not over yet, please click on the next page to continue reading! If he let this go, he would still be "sick and scratching".
"Touch-Down."
"COG-Distance."
Especially the latter, which means the distance between the projection point of our body's center of gravity and the landing point at the moment of bottoming out.
"As long as we link these key points, we can always place our center of gravity projection point in front of the landing point. In this way, the TRF, which is the ground reaction force, will not be so far back, and the braking force will be further
Reduced. And the reaction force on my body from the ground can be moved further forward."
"In this case, the TRF will be shortened, and the front side mechanics can naturally be better exerted." Randy didn't even wait for Su Shen to finish speaking, and said to himself: "Wonderful, wonderful! Why didn't I think that it could be like this?
?”
"It's just that it may not be easy to implement."
That's certainly not easy.
Su Shen said in his heart that participating in the indoor competition in 2018 means that he and Coleman have reached excellence.
The rest of the people are all not up to par.
Therefore, if you want to do this, you still need talent and technical understanding, which is not that simple.
However, his knowledge system extends to decades later, and he has a better solution to this problem than he does now.
It can also better bring out the standard technical points of front side mechanics.
"If everything goes well..." Randy started by staring at the running screen on the screen and kept saying: "The back kicking stage is from the vertical support of the body until the toes kick off the ground. The back kicking force of the back kicking legs accelerates the movement.
When the human body is running, the fluctuation of the center of gravity should be small and the forward horizontal component should be large. The forward horizontal component is mainly determined by the back pedaling force and the back pedaling angle. According to the mechanical principles of human body movement, the power of human body movement is
The muscle contraction of the back kicking leg produces muscle tension and the ground produces a back kicking force. At the same time, the ground provides an equal and opposite supporting reaction force to the human body..."
"Therefore, the back kicking angle of the bent back kicking technique and the forward inclination angle of the calf can be smaller than the angle of the "traditional back kicking" technique. The smaller the back kicking angle, the greater the support reaction force generated by the contraction of the back kicking leg muscles.
The component force will naturally be larger, which will also naturally increase the horizontal displacement speed of the human body and reduce the fluctuation difference of the center of gravity."
"In this way, everything is cleared up. The technical difficulties and technical connection nodes of the entire system have been described in a relatively complete manner. When the time comes, there will be no need to cross the river by feeling the stones, and we can just follow the steps step by step."
As he spoke, Randy's eyes became excited, showing a genuine excitement about track and field knowledge.
"No wonder you and Ralph attach so much importance to the development and research in this area during this period. Once solved, the key to back-pedaling technology in actual running, that is, it is the source of forward power, will be broken through. If you deliberately
Flexing the back kicking leg is necessary to affect the effect of the back kicking force, but on the contrary, it affects the effect of the front swing. Therefore... the "flexed kicking style" back kicking technique should be regarded as the concept of kicking timing: 'the kicking leg has not yet
Quick folding technology before lifting off the ground and even better half folding technology'."
"This allows the back kicking leg to maintain a certain degree of flexion, while also achieving the purpose of rapid folding naturally and effortlessly."
"It is no longer necessary to actively engage in folding and rely more on folding, as is the case with the current mainstream research on O&M."
"Even in the future..."
"Folding technology may be completely outdated or even backward."
"You'll know then, Mr. Randy."
Su Shen looked at Randy, his eyes seemed to carry the light of the future, and said: "Compared with this kind of folding running method that is now popular in Omi, the work time will seem too long. As long as this theory can be transformed into actual combat
Among them, combined with other technical adjustments in place..."
"The new system, new mainstream, and new era of sprinting are already beginning to beckon."
"And we..."
"He is the initiator and pioneer of a new era."
Randy has always believed that the lighthouse's sports research and light are the brightest.
This is not arrogance, just fact.
but now……
He noticed the young man in front of him and the light in his eyes.
Maybe not the brightest one.
But it might be.
The farthest one.
…
The days are passing day by day.
The world's track and field field is preparing intensively for competition.
News about the Olympics is also progressing steadily.
Firstly, the Olympic Organizing Committee has also begun to announce venue information and competition events. Secondly, London's recent tax exemption policy has also begun to appear.
This is to avoid the previous situation where big-name athletes were unable to come because the tax rate was too high.
Although it will only return to normal after the Olympics.
But this year, most of the time, we will definitely be in the "athlete tax exemption" state.
This is undoubtedly good news for big-name athletes around the world.
Otherwise, all the money earned will be used to work for the government of Kitty Hawk, which no one can bear.
Secondly, yesterday, major betting companies gave the latest winning odds for Olympic track and field events. Taking the 110-meter hurdles as an example, the defending champion Robles topped the list, followed by Liu Xiang in second, American players Richardson and
Oliver ranked third.
There is still no trace of Merritt, because he has only achieved good results in indoor races and has not proven it in outdoor races. It is normal to give odds like this. But Su Shen knows that Merritt’s odds will be
Showing rocket speed this year.
Su Shen also came out in the 100 meters. There is no doubt that Bolt is first, Gay is second, Powell is third, Su Shen is fourth, and Blake is fifth. Su Shen ranks so low, mainly because of him
Compared with his 60-meter state and his peak period, there is a slight gap in performance, and he is still recognized as an extremely promising type.
Naturally, it’s not surprising that he ranks at the back.
This time it's not really "hard black", it's just "black" in a natural way.
Domestic news has also begun to be announced. The first is the short span. In the 110-meter hurdles, five domestic athletes have reached the Olympic A standard. This is a historic event that may not even allow Asia's second-biggest brother Shi Dongpeng to have a chance to continue competing.
In the 100-meter race, there are more than six or seven people who have reached the standard so far. There are only three places in the Olympics, and there is no wild card support. This year's 100-meter race trials have already been declared to be the most "bloody and cruel" in domestic history.
" once.
Even the top ten masters are not stable this time.
If you are not careful, you will stumble and lose the battle.
This resulted in tickets for this year's Olympic trials starting to be snapped up as soon as they came out.
Even track and field fans don’t want to miss this wonderful historical moment.
In such a golden age, who knows when the next one will be?
If you can't watch the Olympic Games live, it's good to watch your own people's peak showdown in China.
At present, except for North America, even the 100-meter race in Europe is not as good as our own "infighting".
As the intensity of competition increases, naturally more people will be willing to pay.
This is a perfectly relevant example.
The atmosphere inside Ersha Island is becoming more and more tense day by day.
This is a visible "tension".
Especially those who want to sprint for a spot are doing their best to step on the accelerator for the final stage of their winter training.
At this time, Jamaica has begun to take the lead in outdoor competitions.
Yohan Blake achieved a good result of 9.85s in one breath at the Kingston Invitational. Although the wind speed was not bad, the result was solid.
During the interview, Blake also said: "I'm just setting an example for everyone."
"9.85s is definitely just an ordinary result this year, just a passing mark."
"I will also go all out for the Olympics this year."
After Blake opened the hole, Guy also came out for 9.85s, and the wind speed was smaller.
Gatlin also made a strong comeback. He actually ran a time of 9.85s, which was a strong announcement...
Return yourself to the position of being a strong person.
He also has to have a hand in this year's Olympics.
Powell ran a time of 9.88s in light wind conditions. In terms of hard power, he might actually be better than them, but it had to be no worse.
After these people started to produce good results continuously, track and field fans all over the world also received some kind of signal————
This year’s results of 9.80 are expected to be endless.
An even more intense season year.
About to start.
The only top runners who are not running now are Bolt and Su Shen who have not exerted their strength yet.
worldwide.
They were also staring at these two brothers.
PS: I don’t know why. I have a fever and cough. It may be mycoplasma pneumonia or influenza A. Alas, it’s really difficult.
Today is not good, I’ll just go get an injection tomorrow, alas, o(╥﹏╥)o~~~~~~~~~~~~~~~
