Chapter 1994 asked, how strong are the yellow people with the most fast-twitch muscle fibers in the world?
"The fifth path."
"The only player who has a chance to threaten Su Shen."
"He is the world record holder in the men's 100 meters and 200 meters, the Black Lightning of Jamaica, Usain Bolt."
"Bolt is said to have come prepared for this competition. The interview before the competition made it very clear that he is not here to compete for second place. He is here to break the 60-meter myth of Su's invincibility."
"I originally thought that even if Bolt said this, there would be little feasibility. In the 60-meter field, Dongfang Su has always been the best."
"But Bolt's performance in the semifinals makes me feel hopeful again."
"He has already achieved extremely strong results."
"If all the semi-finals had not broken the world record, then it would have been Bolt's turn to hold the current 60-meter record."
"A difference of 0.01 seconds."
"Makes me feel like anything is possible."
"Just like Su said before—"
"The Myth of Athletics."
"It was meant to be broken."
"Then if Bolt comes to break it."
"It means that all the records of 60 meters, 100 meters, 150 meters and 200 meters are occupied by Bolt. Then Bolt's position as the first man in history will be unshakable."
The on-site commentator followed the camera and explained Bolt.
Bolt's mentality has been adjusted well now.
The spiritual coaching buff that Else gave him before the game was not in vain.
Although he had just felt that Su Shen's words and performance were very domineering, now was not the time to appreciate his opponent's domineering performance.
Bolt looks into the camera.
He also beat his chest and said, "Who is the legend?"
"It's me."
"Who is the king of sprinting?"
"It's me."
“Who is serious about being invincible?”
"It's me."
"100 meters, 150 meters, 200 meters, now..."
"It's 60 meters' turn."
After Bolt finished speaking, the crowd cheered.
Everyone was excited about Bolt's remarks.
It is no longer a battle between blacks and whites.
Now it has become a battle between Europeans and Americans and Easterners.
And from Jamaica on the Caribbean coast.
Now it is automatically planned to be included in the ranks of Europe and the United States.
It is to combat and suppress the rise of the Easterners.
After any behavior reaches a certain height.
In this society, there will be a certain degree of political overtones.
Bolt and Su Shen actually feel this.
But now two people have been pushed to this position.
None of them will let their opponents step on them easily.
Then you can only aim to defeat your opponent.
After Bolt finished speaking, he still looked at Su Shen, but this oriental face didn't have the slapstick look before, he just looked directly at him like this...
Do you think it’s strange?
People are just so weird.
Bolt obviously looks at others first.
At this time, because people looked directly at him without flinching, he felt annoyed.
On the contrary, the anger inside was rising.
It feels like...
When he looked at it, he had to bow his head and give in.
Don’t you give in?
That all lit the fire.
Naturally, Su Shen could no longer dodge.
It was true that my strength could not keep up before. I still need time and space to grow. If I force myself to be strong, I will only be at a disadvantage. There is no need to know that it is unwise to force yourself when you are at a disadvantage. It is easy to let yourself go.
Bringing humiliation to oneself.
Besides, Bolt has never been a merciful person. Before he has the strength, it is best to avoid his sharp edges and hide his strength and bide his time.
That has now ended.
He is about to start challenging Bolt head-on.
In fact, there have been signs since 2011.
Last year, this result was completely announced.
After the London Olympics.
He and Bolt have already entered into this kind of hostile relationship whether you like it or not.
Only one side admits defeat or falls down.
"Sixth Path Yohan Blake."
"He is the fastest 200-meter runner in the Olympic Games. If this was a 200-meter track, I would definitely force him to have a final showdown with Usain Bolt. But this is 60 meters. Bray, the 200-meter champion at last year's London Olympics
If you don't, you can only succumb to others."
"You can only go to the back."
"In this game, it may be difficult for him to enter the top three."
Blake didn't care either.
It's pretty much the same to him anyway.
Even in this game, in order to allow Bolt to be ranked on Su Shen's side, the rules of the draw were temporarily changed.
It means being fair, just and open.
But after competing for so many years.
How could Blake not know the twists and turns inside? It doesn't matter that it's difficult for him to get good results in the 60 meters. He just does what the competition organizing committee says, and it doesn't really mean anything.
His main battlefield is only 100 meters at most, and 60 meters is just for fun.
Besides, he wanted to see it too.
If Bolt evolves again this year, can he really challenge Su Shen on the 60 meters?
It's like the 100-meter Su Shen beat him hard.
"Seventh lane, American athlete, former Olympic champion, world championship champion, Justin Gatlin."
"Gatlin showed good competitive form last year, which further proves that although he is older, his condition is improving."
"It's just a pity that this is the 60-meter track."
Not enough for Gatlin.
Far from enough.
In such a large-scale dragon-slaying event, there is only one person left alive in the United States. He is still a veteran in his peak period, concentrated in the early 21st century.
I feel a little embarrassed to explain myself.
Is America's traditional sprint event going to change hands in the next few years?
Now you know why the TV stations in the United States didn’t broadcast this game at all, right?
There is no need to broadcast it.
And it’s hard to win a medal just by yourself on the stage, so why broadcast this game?
Anyway, Guy and the others are not participating.
It is better to handle this matter as coldly as possible.
Leave him alone for a while.
This chapter is not over yet, please click on the next page to continue reading! The heat will naturally dissipate.
What is flexibility?
The domestic media in the United States are well prepared for this. They know when to focus on reporting and when not to change it.
If you focus on reporting that our athletes are so stupid and miserable in their games, it will give ordinary viewers the impression that American sports have declined significantly.
Then it's better not to broadcast it.
Those who want to watch it can only watch it in Green's live broadcast room.
Now that Green has become bigger and stronger, naturally there are people who will broadcast live broadcasts of every game. He actually wishes that the official media here in the United States would not broadcast the game.
If you want people to watch these games, they will naturally flock to your live broadcast room.
Then this kind of popularity will increase.
His own advertising fees and traffic income will also rise together. Under the inducement of force, how could he not broadcast it? He must broadcast it! He must broadcast it more vigorously!
"The last one is the flower grower contestant, Wen."
"Although Wen is far behind Su in terms of strength, his personal 60-meter performance is not small at all. He has won two bronze medals at the World Indoor Championships."
"This is an honor that many people will never get in their lifetime."
"He is also known as the Little Dragon of the East in Europe."
"It's just that the real owner of this game, Su, is here."
"He can only take a back seat."
"His competitors in this game are people like Gatlin."
"It's not that he's not strong enough, it's just that the people who came today are too strong."
Wen Yongyi has nothing to say.
He knows that his strength is good among ordinary people, but when compared with these monsters...
That's still a bit worse.
As long as he can get a chance in the finals.
Just give it your all in the finals.
Try to push your Pb to the top before your peak is over.
That's enough.
As for medals, he really hadn't thought about this competition.
…
"Okay, ladies and gentlemen."
"The finals are about to begin."
"Let us hold our breath."
"Let's see if Bolt can break Su's 60-meter invincibility myth."
"Let's see if the Eastern Dragon will be defeated in this encirclement and suppression."
"Let's see who the dragon-slaying warrior ends up with."
"Let's see who's head will be hit in the end with a handicap of more than 1 billion US dollars."
"All the suspense will be fully revealed after this shot."
The narrator finished speaking.
Su Shen and others will also stand on their starting blocks again.
At this time, the small electronic speaker behind him also sounded, and the electronic password sounded——
on your marks.
Long-term training has resulted in a high degree of adaptability between Su Shen's nervous system and muscular system. Nerve impulses can be transmitted to the corresponding muscle fibers more quickly and accurately, prompting the muscles to contract rapidly and generate force. At the same time, the muscle fibers also pass through
Adaptive changes occur during training, such as changes in muscle fiber type.
That is, a certain proportion of slow-twitch muscle fibers is converted into fast-twitch muscle fibers and the cross-sectional area of the muscle is increased, allowing the muscle to produce greater force and faster contraction speed.
this……
Is it also trainable???
sure.
Just like height, although the proportion of nature is very large, the proportion of nurture is still not small.
If you are like Su Shen, you will make use of your hard work and nutritional training to make yourself taller.
What about the proportion of fast and slow twitch muscles?
That’s ok too.
It's like starting with nerve impulse transmission.
Long-term training can increase nerve conduction speed. At the synaptic neuromuscular junction between motor neurons and muscles, repeated training makes the release and reception of the neurotransmitter acetylcholine more efficient. The speed of nerve impulse conduction along the axon is accelerated, which
Involving the degree of myelination
Change. For example, long-term training can promote the thickening of the myelin sheath of nerve fibers and speed up the conduction of action potentials. It is like wrapping a thicker insulation layer on a wire, making the electrical signal nerve impulses transmit faster and more accurately.
, thereby allowing the muscles to receive contraction signals faster.
If we start with muscle contraction, the recruitment order and efficiency of a motor neuron and all the muscle fibers it controls changes. After training, the nervous system can more accurately recruit those motor units that can produce greater force and faster contraction speed first.
When explosive force is required, the brain can quickly direct the relevant fast-twitch motor units to participate in the work.
Once these are done, you can build your muscle fiber type according to a certain proportion.
For example, long-term strength or speed training can produce adaptive changes in muscle fiber types.
That's right.
Future scientific papers and the technology in the preface have proven that although there are indeed differences in speed and proportion between human races. The greatest feature of the human species is adaptability.
Start with adaptability.
It can change your original muscle fiber capacity to a certain extent.
Slow-twitch fibers are mainly involved in endurance activities. They contain many mitochondria, rich capillaries, and mainly rely on aerobic metabolism. Fast-twitch fibers contract quickly and are powerful, and mainly rely on anaerobic metabolism for energy. In long-term high-intensity, short-term explosive training
Under stimulation, some slow-twitch muscle fibers will move toward fast-twitch muscle fibers
Transformation is based on the metabolic enzyme system inside the muscle fiber and changes in the type of contractile proteins. For example, some enzymes related to anaerobic metabolism, such as phosphocreatine kinase activity, are higher in fast-twitch muscle fibers. After training, the activity of these enzymes in muscle fibers is higher.
Changes in distribution promote the transformation of muscle fiber types.
This alone is not enough.
A further change is the increase in muscle cross-sectional area.
Strength training will cause micro-damage to muscles and trigger the body's repair mechanism. During the repair process, muscle protein synthesis increases, and the number and thickness of myofibrils increase, causing the muscle cross-sectional area to increase. This type of muscle hypertrophy is mainly through
This is achieved through the activation of satellite cells. Satellite cells
Satellite cells are a kind of myogenic stem cells. After the muscle is stimulated by injury, satellite cells are activated, proliferate and fuse with the original muscle fibers, increasing the number of cell nuclei of the muscle fibers, thus providing more support for muscle protein synthesis and making the muscles become
It is stronger and can produce greater power.
And the younger you start training, the greater your probability and proportion of transformation will be.
Yellow people versus black people and white people.
It also has its own particularities.
That is to say, the overall functions are relatively balanced.
All skills are relatively balanced, which means:
The plasticity is also higher.
As long as you train properly, you can transform yourself into any aspect.
This is a characteristic that black and white people do not possess.
But first you have to learn how to transform.
How to scientifically transform.
Of course the former Su Shen couldn't do it.
No one taught him this.
Coupled with the extremely backward track and field, scientific concepts and training concepts in the country, Su Shen was already very old when he came into contact with him and was about to retire.
Fortunately, it's different now.
He has been paying attention to this aspect almost since he was a child.
Since childhood, I have paid attention to the adaptation of my fast and slow muscles and the transformation of the ratio of fast and slow muscles.
In other words, he changed his body adaptability and muscle adaptability to sprinting from the beginning.
It’s not like you start doing this from a young age. If you want to change it later as an adult, it will become more and more difficult.
Plasticity will also become lower and lower.
This is because, although it is possible to convert muscle fibers to a certain extent, the difficulty is certainly not low.
Muscle fiber type transformation is a complex physiological process.
Under normal circumstances, human muscle fibers are mainly divided into slow-twitch muscle fiber type 1 and fast-twitch muscle fiber type 2, of which type 2 can be subdivided into subtypes such as 2a and 2x. The transformation from slow-twitch muscle fibers to fast-twitch muscle fibers mainly involves the following aspects:
The first is the change in metabolic characteristics. Slow-twitch muscle fibers mainly rely on aerobic metabolism and are rich in mitochondria and capillaries to use oxygen to produce energy. Under the stimulation of long-term strength or speed training, the metabolic pathways in the cells change. Compared with anaerobic metabolism
The activity of related enzymes, such as phosphocreatine kinase, will gradually increase. These enzymes participate in the process of rapid energy supply, making muscle fibers more adaptable to anaerobic metabolism, which is an important metabolic sign of transformation into fast-twitch muscle fibers.
The second is the change of contractile proteins. The contraction of muscle fibers depends on the interaction of actin and myosin. The isoforms of these contractile proteins in fast muscle fibers and slow muscle fibers are different. During the transformation process, the gene expression inside the muscle fibers changes.
, causing the composition of contractile proteins to gradually change to the characteristic proteins of fast muscle fibers, resulting in accelerated contraction speed.
In addition, changes in innervation also play a key role. Motor neurons have a nutrient effect on muscle fibers, and changes in nerve activity patterns, such as long-term high-frequency stimulation, will affect the characteristics of muscle fibers. High-frequency nerve impulse stimulation prompts muscle fibers to adapt to this
The rapid contraction signal is also a factor that induces the transformation of slow-twitch muscle fibers into fast-twitch muscle fibers.
At the same time, supplement creatine, beta-amino acids, and branched-chain amino acids.
Creatine is a substance naturally found in muscles that can help muscle cells store more energy. Supplementing creatine can increase the muscles' creatine phosphate reserves, which is very important for high-intensity, short-term exercise. When performing bursts
During sexual exercise, creatine phosphate can quickly provide energy and promote the function of fast-twitch muscle fibers. Long-term use may indirectly prompt the body to adapt to this energy demand pattern, thereby facilitating the transformation of slow-twitch muscle fibers into fast-twitch muscle fibers to a certain extent.
Beta-amino acid is a non-essential amino acid. Beta-alanine can combine with histidine to form carnosine. Carnosine mainly exists in muscle tissue and is an important intracellular buffer.
During high-intensity exercise, muscles will produce a large amount of hydrogen ions, which will acidify the muscles. Carnosine can help buffer these hydrogen ions and delay the onset of muscle fatigue. This helps improve the ability of high-intensity exercise and creates conditions for muscle fiber type transformation.
, especially has a positive effect on the functional strengthening of fast twitch muscle fibers.
Branched-chain amino acids, including leucine, isoleucine and valine. Leucine is particularly important because it can activate the mammalian target of rapamycin (mTOR) signaling pathway, which is critical for protein synthesis.
important.
Promoting muscle protein synthesis can help muscles recover and grow better after training, and may have a positive impact on the conversion of muscle fiber types in the long term, helping to increase muscle strength and power, which is related to the fast-twitch muscle fibers.
Functional features are consistent.
Therefore a scientific supplement to complete the conversion helps you convert an important model.
This kind of thing didn't exist before.
There isn't even a concept related to this.
Naturally, nothing can be done.
First of all, you need to know these things in order to carry out scientific proportions and scientific intakes to help you complete scientific conversions.
at this point.
Su Shen is a person who will come decades in the future.
Know all about these things.
He also knows what should be done to better complete the conversion.
He is 23 years old this year.
After 10 years of hard training, all the functional indicators of his body have finally begun to reach their absolute peak.
In addition to the technical system, major changes such as changing the feet were completed last year.
This year he.
He is the one who really wants to show his ability.
This time.
The proportion of fast and slow twitch muscles in his body.
It has reached its highest peak since reopening.
Usain.
Asafa.
Youhan.
And Tyson Gay, who is not here, etc.
Even coaches like Mills Francis.
You've never seen yellow people with truly developed fast and slow muscles, have you?
