The Su God of the Reopening of the Sports Arena

Chapter 1634 You, you know again? Another new technology is born!

[London florist’s guess for the Olympic flag bearer: men’s basketball tradition, track and field new talent. 】

Less than half a year before the opening of the London Olympics, according to usual practice, the candidates for the Olympic flag bearer of the Chinese Legion have become the focus of attention from the outside world. After Yao Ming missed the London Olympics, it was difficult to find a cross-field and cross-era leader in the domestic delegation. Olympic qualifications, athletic performance, and international influence are the three main factors that determine whether you can become an Olympic flag-bearer. Whether it is Yi Jianlian, Wang Zhizhi, Li Na, Liu Xiang, or Su Shen, everyone has the opportunity to raise the bright five-star red flag on July 3, marking the beginning of our country's march towards the London Olympics.

Zhonghua's candidates for Olympic flag bearers seem to have always favored men's basketball players: starting from the 1984 Los Angeles Olympics, Wang, Song, Liu Yu and Yao have been the flag bearers of the Chinese delegation for seven consecutive Olympic Games. Compared with athletes in other sports, men's basketball players are uniquely qualified to serve as flag bearers. They are tall, handsome, and have strong fighting spirit. By having them serve as flag-bearers, they can better reflect the spirit and momentum of the Chinese delegation.

The possibility of Li is relatively small, and the track and field army may suddenly emerge.

In the London Olympics, Liu Xiang must regard winning gold as his only goal. There is a sense of revenge and the idea of ​​​​breaking through himself. In addition, there are many netizens who recommend Liu Xiang as the Olympic flag bearer. No matter what, Liu Xiang has proven with his strength that he is fully qualified to be the Olympic flag bearer.

Su Shen also has this self. He made a blockbuster success in Daegu last year, breaking the record of Asians with yellow skin unable to win the OW title. He created the first historic gold medal for the entire yellow race in the 100 meters, and he also has this qualification.

Whether it's Alian, Li Na, Liu Xiang or Su Shen, their good public image, strong international influence and outstanding sports performance are enough to make them worthy of the honor of flag bearer. No matter who is ultimately elected, they will leave a mark in the history of our country’s Olympic campaign.

[As the Olympic Games approach, various Olympic medal prediction lists have been released. Among them, the "Virtual Olympic Medal List" produced by the Dutch company Infostrada Sports has attracted the attention of European and American mainstream media. 】

The authoritative data website Infostrada Sports has been engaged in event data analysis and statistics for many years. They calculated the data elements of a total of 302 events in the London Olympics, used supercomputers to calculate the dynamic rankings of the top eight players, and updated the list every month.

Su Shen is currently ranked third, and Liu Xiang is temporarily ranked second.

[Rival coach Liu Xiang made rapid progress after eight improvements and seven improvements: Breaking 13 seconds this year]

Merritt's coach Behm believes that Merritt's physical coordination is incredible, which is not unrelated to the fact that he practiced gymnastics before turning into a hurdler. Likewise, Merritt's long thighs made up for his height disadvantage.

Coach Merritt admitted that the first five hurdles were his shortcomings, but they have now been resolved, so he can focus on strength training to ensure that the last five hurdles maintain his original speed during the game. Currently, Americans occupy 5 of the top 5 men's 110-meter hurdles rankings in the world. Therefore, Merritt believes that the National Olympic Trials are more difficult than the Olympic Games. Only the top three people will have the opportunity to participate in the Olympics, and he himself There is a very good chance to be selected for the national team. But if he wants to be among the best in the world, he must improve on his personal best of 10 seconds set in 6.

Still, Bem has full confidence in Merritt. "We haven't run an outdoor race yet, but all signs are that Merritt should break the 13-second mark this year," he said.

……

News about the Olympic Games began to increase gradually.

The Olympic Games, held every four years, are also a grand event around the world, not just for sports fans, but also for many people who don't usually watch games.

At this time, everyone will watch the TV, at least to see the performance of domestic athletes.

In Ersha Island, Su Shen is making adjustments and technical changes in the later stage.

"The force of the back kick is relatively small, but it greatly increases the speed of the back kick, shortens the support time of the back kick, and accordingly shortens the airborne time, making it easier to coordinate the swinging movements of the two legs... In this way, it will actually The ability to increase the cadence." Randy looked at Su Shen's training courses. The last few training sessions have indeed been much better than before. Although the technical points have not been connected yet, as long as it can be considered effective, it will be sooner or later. matter.

He now has no doubts about Su Shen's ability to understand the technical points.

If it was all "little troubles" before, then this year's large-scale technical changes and foot changes have completely refreshed Randy's judgment on Su Shen's technical ability and talent. In the past, he might have thought that Su Shen had a level of technical understanding at the level of President Mountain in the world. But after this winter training, Randy no longer thinks so. He now feels that Su Shen is not President Mountain...

How old is this technically gifted "president" without a "mountain"?

His ability in this area is already the same as Bolt's track and field body, which completely separates him from the rest.

Not on the same level at all.

"So now I think you can further increase the cadence. If you want to improve further, the stride length must also increase again." Randy said: "Your recent physical condition is getting better and better. I think before London, Your physical condition and muscle condition should be able to return to the level of Daegu last year. But now that you have changed to front-side mechanical drive, and your cadence has improved, I think..."

Randy looked at the 3D data feedback of the "Champion Model", touched his chin and stared at the screen, raised his head on the right side of his mouth, and said: "I now think your stride length is not matching enough, and the calculated data is not golden enough."

"Although your stride length will not be bad after you switch to the bent-pedal back-pedaling technique, and you may be able to win even more after your body returns to peak strength, it is still not good enough, and you are still far from excellent data. "

"Well... the essence of the movement of the human body is the forefoot as the support point, the calf as the lever, and the weight is added to the ankle joint through the calf bone. The support reaction force experienced by the human body at this time is composed of gravity, inertial force and muscle The contraction force is synthesized when the gastrocnemius muscle contracts near a fixed position. Due to the fixed rotation axis of the ankle joint, while the heel is subjected to a pulling force along the direction of the calf, the fulcrum is also subjected to a backward push force in the opposite direction. The reaction force of this push force is It's also part of the support reaction force, so..." Randy was still staring at the model feedback on the screen, constantly thinking about how to improve it, but again, Su Shen had said it before. He asked Randy to come over, mainly. It is to help you discover problems from the perspective of a bystander that are difficult to find from your first perspective.

Therefore, as long as the problem can be discovered, the remaining part can be completed by Su Shen with his super-era knowledge.

"If the angle between the calf and the ground can be reduced, the angle between the support reaction force and the ground will also be reduced." When Su Shen came over to drink water, he glanced at the screen and followed Randy's words.

"Yes, if the angle between the calf and the ground can be reduced, the angle between the support reaction force and the ground will also be reduced. It is indeed possible, huh???" Randy said, Su Shen suddenly turned to look at the side and said in astonishment: "This, you know this again???" Looking at the data feedback, he was still thinking about the source of the problem, but they just took a look and reported it directly. Answer?

And when talking to Randy, a master-level coach, you definitely can't give just one answer.

In addition to the answer, you also need to provide a process and an argument that Randy can be convinced of.

Otherwise, for such a master-level figure, if you want to give him a standard answer like in ordinary urban novels, people will accept him and worship him. That is absolutely impossible to happen in reality.

Process, how to break down the process of how to get the answer.

That's what really convinces people.

And this is often the most difficult point.

However, this was not difficult for Su Shen. He wiped his sweat and said casually: "From the analysis of running technical movements, during the back pedaling stage, preventing the knee joint from excessively extending backward can keep the calf and the ground relatively close. Small angle. However, the traditional "back-pedaling" technique overemphasizes the full extension of the knee joint when pedaling, resulting in a large pedaling angle, a small forward lean of the calf, and a large angle with the ground, which is not conducive to improving the linearity of running. and forwardness. Although the size of the horizontal force component of the human body during jumping is determined by the back-pedaling force and the back-pedaling angle, when the back-pedaling force is constant, the determining factor depends on the size of the back-pedaling angle, not the back-pedaling angle. Kick for power.”

"So……"

"For example."

Su Shen took out a pen and wrote on the whiteboard placed next to him:

“如甲乙两个运动员，后蹬力量F均为100kg，甲的后蹬角为47°，乙的后蹬角为55°，则有：甲：Fx=Fcos47°=68．2kg、Fy=Fsin47°=73．1kg。”

“乙：Fx=Fcos55°=57．4kg、Fy=Fsin55°=81．9kg。”

"Comparing the two, the answer comes out. B's Fx is only 84% of A's, while Fy is 2% of A's. Obviously, A's forwardness when running is better than B's."

Su Shen finished writing on the whiteboard, then put down the pen and said: "This shows that the "traditional back-pedaling" technology is superior to the "straight-pedaling" technology. During the back-pedaling, the supporting leg is not required to push hard and stretch too early, but Wait until the center of gravity has moved far beyond the support point before kicking back. In this way, the calf tilts forward greatly, the back kicking angle is small, and the body's center of gravity fluctuates slightly when running. This increases the forward horizontal component and reduces the upward vertical movement of the human body. The force distribution increases the horizontal displacement speed of the human body, which is beneficial to the improvement of running speed."

Randy stared at it for a while before continuing to ask: "Then there is a problem here, and I think it is still unresolved."

Randy is indeed a master. He will "get to the bottom of everything" when looking at a problem. It doesn't mean that you can just look at something and fool him if you don't understand.

Su Shen was also used to waiting for Randy to see if what Randy was going to say was the same as what he thought.

If the same.

It just brings out a new technical concept.

"That is, even the angle can be done well, but what about the matching of strength and angle? And how to make the torso position, hip position, and especially the previous transition smooth and easy? The variables here are probably not small, Su .”

"And how to make the folding work properly during exercise is still not solved."

After hearing this, Su Shen smiled with satisfaction and said: "Yes, if you want to use the curled pedal to increase the stride length, of course it will not be that simple. A new technical concept needs to be applied here as a connection point. Let me name it: "

"Half-folding technology."

"Semi-folding technology? Su, did you create it yourself? Then... what should it be called in English?"

Randy never imagined that one day he would ask someone what the English translation of new technology was.

Su Shen smiled and said: "No, this is a new thing that Mr. Ralph Mann and I studied together. It is used to supplement some new technical points of front side mechanics. In English, let me think about it..."

"It's called..."

"Low heel."
