Chapter 1628 You, you know again? Another new technology is born!
[London florist’s guess about 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 candidate for the Olympic flag bearer of the Chinese Legion has 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 will have a chance to win in July.
On the 27th, the bright five-star red flag was raised, marking the beginning of our country's march towards the London Olympics.
The selection of Olympic flag bearers seems 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,
The men's basketball team members 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 have regarded winning the gold medal 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
, he fully meets the standards of an Olympic flag bearer.
Su Shen also has this in him. He made a sensation in Daegu last year, breaking the record of Asians with yellow skin being unable to win the OW. He also created the first historic gold medal for yellow people in the 100 meters. He also has this qualification.
Whether it is 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 finally elected,
It 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, and 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 body coordination is incredible, which is not unrelated to the fact that he practiced gymnastics before turning into a hurdler. Similarly, Merritt's slender thighs also make up for his incredible performance in the field.
Height disadvantage.
Coach Merritt admitted frankly that the first 5 hurdles were his shortcomings, but they have now been resolved, so he can focus on strength training to ensure that the last 5 hurdles maintain the original speed in the game. Currently, in the world men's 110 meters
Americans occupy 6 of the top 10 hurdles rankings. Therefore, Merritt believes that the National Olympic Trials are more difficult than the Olympic Games. Only the top 3 people will have the opportunity to participate in the Olympics, and he himself has a very good chance of being 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 13.09 seconds set in 2007.
Still, Behm is confident in Merritt. "We haven't run an outdoor race yet, but all signs point to 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, we would all watch TV, at least watching the performance of domestic athletes.
In Ersha Island, Su Shen is making adjustments and technical changes in the later stages.
"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 happen sooner or later.
matter.
He now has no doubts about Su Shen's ability to understand 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 may have thought that Su Shen was the world's president.
level of technical understanding, so after this winter training, Randy no longer thinks so. He now feels that Su Shen is not Presidential Mountain...
How old is this technically gifted "president" who has no "mountain"?
His ability in this area is already the same as Bolt's track and field body, which completely sets him apart 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 it has been 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 its peak strength, it is still not good enough and is still far from excellent data.
"
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "Well... the essence of human body movement 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 a combination of gravity, inertia force and muscle contraction force. When the gastrocnemius muscle contracts near a fixed point, due to the fixed rotation axis of the ankle joint, the heel is subjected to a pulling force along the direction of the calf and at the same time, the fulcrum
It is also subject to a backward thrust in the opposite direction, and the reaction force of this backward thrust is 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 he still said the same sentence
Well, Su Shen had said before that he asked Randy to come here mainly to help him find problems from the perspective of a bystander that were difficult to find from his own first-hand 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 Su Shen aside and said in astonishment: "This, you know this again???"
I was looking at this data feedback and was still thinking about the source of the problem, but someone just took a look at it and reported the answer directly?
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 extending too far 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 strength.”
"So……"
"Let's use an analogy."
Su Shen took out a pen and wrote on the whiteboard placed next to him:
"For example, two athletes A and B have a back-pedaling force F of 100kg, A's back-pedaling angle is 47°, and B's back-pedaling angle is 55°, then: A: Fx=Fcos47°=68.2kg, Fy=Fsin47°
=73.1kg.”
"B: Fx=Fcos55°=57.4kg, Fy=Fsin55°=81.9kg."
"Comparing the two, the answer comes out. B's Fx is only 84.2% of A's, while Fy is 112% 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 component increases the horizontal displacement speed of the human body, which is beneficial to increasing 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 is also used to waiting for Randy to see if what Randy wants to say is the same as what he thinks.
If the same.
It just introduces a new technical concept.
"That is, even the angle can be done well, but what about the matching of strength and angle? There is also the position of the torso, the position of the hip, especially how to make 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."
