Randy never thought that she had to know Chinese before she could know the technical words in English.

This has never happened in his counseling career.

This is also a novel experience.

"Semi-folding technology?" Randy thought for a while and said, "What exactly is it like?"

"Many people in China want to fold too actively, which will make the calf turn too fast to increase the pace frequency, but there will be many such problems." Su Shen replied patiently: "Then there will be problems in the time of vacancies."

"No folding?" Randy was stunned. The joke was going to be big. This was no smaller than the previous theory and bombing as an example. After all, the whole world is vigorously promoting folding. Do you think you want to challenge the whole world?

"No, no, no." Su Shen shook his head immediately and said, "No, it's not like this, it's not that it doesn't fold. Our laboratory has recently proved a problem, that is, the foot on the ground you want to slid the ground quickly, and the other foot cannot be hooked too much."

"How can I get over?" Randy said in shock.

"From this place." Su Shen used his body to make an example, and passed his hand closer to the lower position, and said, "Then stretch the other leg upwards, otherwise your speed will decrease."

"this……"

"But how to get over it?" Randy was still a little confused. Su Shen began to propose another concept at this time.

“Low heel recovery.”

"Low heel recovery?" Randy said in surprise: "What is this new noun? What is the English name?"

When I was with Su Shen, I really felt that I heard new things every day, and the difficulty of innovation seemed to be with him, and it did not exist at all.

"For the time being, it is called Low-Hell-Recovery."

"Low-Hell-Recovery?" Randy repeated it normally, feeling that she had learned a lot of new nouns 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 finish watching.

After reading it several times, Su Shen asked, "Did you see something?"

"This..." Randy looked at it carefully several times, and after thinking about it, she frowned and said, "It seems to be in the process of running in the air..."

"Your ankle has never crossed this line?"

"That's right." Su Shen snapped his fingers, worthy of being Randy, and it was indeed easy to understand these details.

"That is, the angle that will occur when you step back your ankle and cross the knee of the front leg. At present, 82~87 degrees is a relatively ideal state. And compared to individuals, it is bigger and better. The bigger the bigger it is, the closer it is to the ground, and the explosion and operation will be better. Of course, it should be combined with the remaining technical details. All technologies are for practical purposes, otherwise there will be no meaning."

Randy looked in front of the computer, thought for a moment, and seemed to have thought of something at once. He looked at Su Shen and suddenly said, "No, no, you..."

"Did you solve that biggest problem quietly?"

The reason why Randy is like this is because in the process of changing from back-side technology to front-side technology (note that it is technology, not mechanics), there is a systematic problem that is difficult to solve, that is, in fact, front-back-side technology actually exists all the time during the running process.

There is no only a simple front-side technology or a simple back-side technology.

It depends on two proportions.

If someone says that he is all front-side technology and has no back-side, he must be an outsider and you don’t know how to fool you.

In fact, an excellent athlete in running has both front and rear skills, which is the normal running line.

Otherwise, only the front side will fall, and only the back side will chew shit.

So the question is, why Randy is so shocked, even more stunned than just now, is mainly the front and back technology. So far, there is no particularly good solution to truly integrate and match. Moreover, the technical concepts of the front and back are all novel things. Many people have not figured it out in their research. Do you still ask them to match them?

That's simply a tough guy, and it's even harder than having a sumo wrestler run a marathon.

What Su Shen meant is that he had discovered one of the nodes connecting these two technologies.

"The two points have the shortest straight distance. I believe everyone knows this. So how to reduce the swing time?" Su Shen pointed the English words on the whiteboard with his hand and said with a smile: "This is one of the answer puzzles."

“If it can be done well.”

"Then the process of turning from the backside technology to the front side technology and restoring the front side technology from the backside technology... the swing time will be greatly reduced and reduced."

"In this way, the mutual use of the rear and front technologies will be smoother and more smooth, and the proportions can be more harmonized. Moreover... this can better match the front mechanics, and further utilize and develop the advantages of front mechanics."

"Then..." Randy looked at the smiling Su Shen, opened her mouth and said a few more times before asking the last question: "Where is that key point? Have you found it?"

If you don’t know the key points, then you will still stay in theory and cannot be put into practice immediately.

That may be of great significance to the future, but it does not mean much to the present.

Especially now that everyone is preparing for the Olympics, there is really no time to waste it.

"Well, I found it." Su Shen nodded and said, "TD and COG."

"What, what does it mean?" Randy really felt that his mind was not enough today. He said three words without saying "what does it mean". He himself felt a little funny. He had never seen such a situation after so many years of coaching.

It feels like a primary school student.

However, he was eager for knowledge and saw something new, so he couldn't send it to him to understand.

After all, he devoted himself to track and field all his life and did not even get married.

This chapter is not finished yet, please click on the next page to continue reading the exciting content behind! If this is missed, he will not be able to "grab the heart and lungs".

“Touch-Down.”

“COG-Distance.”

Especially the latter, which means the distance between the projection point of the center of gravity of our body and the landing point at the moment of bottoming out.

"As long as we link these key points, we can always put our center of gravity projection point before the landing point, so the reaction force of TRF, that is, the ground will not be so backward, and the braking force will be further reduced. Moreover, the reaction force of the ground on my body can also be further forward."

"In this way, the TRF will be shortened, and the front mechanics can naturally be better played." Randy said to herself before she could finish Su Shen's words: "Mire, wonderful! Why didn't I think this would be possible?"

"It's probably not easy to implement."

That certainly is not easy.

Su Shen thought in his heart that he and Coleman had achieved excellence in the indoor competition in 2018.

All the others did not meet the standards and were excellent.

Therefore, if you want to do this, you also need talent and technical understanding, which is not that simple.

However, after his knowledge system was extended to decades, he had a better solution to this problem than he is now.

It can also better exert this front side mechanical standard technical point.

"If that goes well..." Randy began to stare at the screen running, and kept saying: "The rear pedal stage is to support the body vertically until the toes are pushed off the ground. The rear pedal force is generated by the rear pedal force for acceleration. When the human body is running, the center of gravity fluctuates small, and the forward horizontal component must be large. The forward horizontal component is mainly determined by the rear pedal force and the rear pedal angle. 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 rear pedal legs and the muscle tension generated by the ground. At the same time, the ground gives the human body a support reaction force with the opposite direction... "

"Therefore, the rear pedal angle of the bent pedal-type rear pedal technology and the forward inclination angle of the calf can be smaller than that of the "traditional rear pedal-type" technology. The smaller the rear pedal angle, the higher the horizontal component of the support reaction force generated by the contraction of the rear pedal-leg muscles, and naturally increases the horizontal displacement speed of the human body and reduces the fluctuation difference in the center of gravity."

"In this way, everything will be understood. The technical difficulties and technical connection nodes of the entire system have a relatively complete expression. You don't need to cross the river by feeling the stones when you advance. You can just follow the steps."

As he spoke, Randy's eyes were excited, which was a kind of excitement about track and field knowledge from the bottom of his heart.

"No wonder you and Ralph attached so much importance to the development and research of this aspect during this period. Once solved, the key to the rear pedal technology in actual running, that is, it is the source of forward power, will be broken. If the rear pedal leg is deliberately bent, it will be necessary to affect the effect of the rear pedal force, and instead affect the effect of the forward swing. Therefore... the "flexive" rear pedal technology should be regarded as in the concept of the timing of the ground: 'The rapid folding technology before the ground leg is even a better semi-folding technology'."

"This can not only maintain a certain degree of bending and bending of the rear kick leg, but also naturally, and achieve the purpose of rapid folding without any effort."

"There is no longer a need to do this with the current mainstream research of Ome, and we have begun to actively work hard to fold and rely more on folding."

“Even in the future…”

"The folding technology may be completely outdated or even backward."

"You will know then, Mr. Randy."

Su Shen looked at Randy, and his eyes seemed to have the light of the future path, saying: "Compared with this type, the folding running method that Ome now is popular now, the work time will be too long. As long as this theory can be transformed into actual combat, and combined with other technologies to adjust it in place..."

"The new system, new mainstream, and new era of sprinting are already starting to wave."

"And we..."

"It is the pioneer and pioneer of the new era."

Randy has always believed that the sports research and light of the Lighthouse are the brightest.

This is not arrogance, it is just a fact.

But now...

He found the light in his eyes of the young man in front of him.

Maybe not the brightest one.

But it may be.

The farthest one.

...

Days pass by day.

The track and field are under intense preparations all over the world.

News about the Olympics is also going steadily.

First, the Olympic Organizing Committee has also begun to publish venue information and competition events, and secondly, London's recent tax exemption policy has also begun to appear.

It is to avoid the situation where big-name athletes cannot come due to the high tax rate before.

Although it will return to normal only after the Olympics.

But this year is definitely the most of the time, and it is in a state of "athletes are exempt from taxes".

This is undoubtedly good news for big-name athletes around the world.

Otherwise, the money earned would be given to the Little Eagle Government, and no one could stand it.

Secondly, major bookmakers gave the latest Olympic track and field championship odds. Taking the 110-meter hurdles as an example, Robles' defending champion ranked first, Liu Xiang followed second, with American athletes Richardson and Oliver ranked third.

Merritt still has no sign because he can only achieve a good result in indoor races and has not proven it in outdoor races. It is normal to give odds like this. However, Su Shen knew that Merritt's odds will increase in rocket speed this year.

The 100 meters on Su Shen's side have also come out. There is no doubt that Bolt is first, Guy is second, Powell is third, Su Shen is fourth, and Blake is fifth. Su Shen is ranked behind this, mainly because his 60-meter state is compared with his peak period, and his grades are somewhat different, and he is also recognized as an extreme future type.

It is not uncommon to be naturally ranked behind.

This time it was not considered a "hard black", it was just a natural "black".

Various news has also begun to be announced in China, first of all, the short span, and the 110-meter hurdles of the domestic five people reached the Olympic A standard. This historic one may not even give Asian second brother Shi Dongpeng the chance to continue competing.

This chapter is not over, please click on the next page to continue reading! In terms of the 100-meter, there are more than six or seven people who have met the standards so far, and there are only three places in the Olympics, and there is no support from wild card. This year's 100-meter battle selection competition has been called out, which will be the most "bloody and cruel" in domestic history.

Even if you break the ten masters, this time it is unstable.

Anyone who is not careful will lose his way and lose.

This has led to the tickets for this year's Olympic Trials being snatched 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, do you know when the next time will be?

It is also good to not be able to watch the Olympics scene, but to see the peak showdown of our own people in the country.

At present, except for North America, even the 100-meter race in Europe is not as good as our own "in-fight".

As the competition intensity increases, there are naturally more people willing to pay.

This is a most positively correlated example.

The atmosphere inside Ersha Island is getting more and more tense day by day.

This is a kind of "tension" that can be seen by the naked eye.

Especially those who want to sprint for the quota are doing their best to step on the accelerator for the final stage of their winter training.

At this moment, Jamaica had already begun to play in the outdoor competition first.

Yuhan Blake scored a good score of 9.85s in one breath at the Kingston Invitational. Although the wind speed was good, the results were also real.

During the interview, Blake also said, "I'm just giving you a sample."

"9.85s is definitely just a regular result this year, just a standard line."

"I will also do my best for the Olympics this year."

After Blake opened the hole, Guy also rushed for 9.85s, and the wind speed was smaller.

Gatlin also made a strong comeback, and he actually scored 9.85s, even if he was strong...

Return to the position of a strong man.

He also has to make a move at this year's Olympics.

Powell ran for 9.88s in the case of Xiaofeng. According to his hard strength, he might actually be better than them, so he had to be fine.

After these people began to produce good results in succession, track and field fans all over the world also received some signal———

This year's 9.80 results are expected to emerge one after another.

A more intense season.

It's about to begin.

And now the top experts who have not run are Bolt and Su Shen who have not yet exerted their strength.

worldwide.

They are 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 so difficult.

Today is not good, so I'll go for an injection tomorrow. Alas, o(╥﹏╥)o~~~~~~~~~~~~~~~~~~~~
