Testing continues.
Next is the biggest highlight.
It is also what everyone loves to watch in recent years.
Because Su Shen and Zhao Haohuan no longer participate, then working and resting with Zhang Peimeng has become the focus of competition.
These two people have been fighting fiercely.
Every time they are facing each other.
However, last year, I lost a lot of work and rest, and eventually I did not qualify for the individual competition to go to the Olympics.
I could only watch Zhang Peimeng shine and heat up on it.
Break through yourself.
This made him feel very sorry.
In addition, he feels that he has "not much time" now, although he is the latest in the first team in Ersha Island.
But in fact, he is the oldest.
Do you think he will feel time tight?
In this urgent environment.
Working and resting have already put myself in full force.
I'm just waiting for another battle with Zhang Peiming this year.
While I am still at the peak.
Although this year is not as cruel as last year's Olympics.
Ersha Island has already obtained a wild card.
Both of them can go.
but.
I also want to make a sigh of relief when I work and rest.
When he returned to winter training, because there was no help from a doctor like Hu Kai, he also privately found Su Shen.
Seeing his somewhat entangled look, Su Shen smiled and made some analysis for him-
First of all, work and rest should be more important than strengthening the body.
It's been so long, and it's too late to change it.
And it's not necessary.
Just Su Shen seems to be a very suitable way to work and rest.
So how to solve it?
Su Shen proposed a point here.
That is the common problem of work and rest.
The straightness of the running is not enough.
This is also because he has a very long stride running method.
This problem will naturally occur.
Then we need to carry out targeted reinforcement.
And at this point, we must do it more meticulously and scientifically.
"How to do it?" Lao Yi asked Su Shen this question.
He himself knows this problem.
His team knows it too.
But want to do better.
How easy is it?
He has optimized it once.
Optimize to the degree of optimization.
Neither he nor his team have any confidence.
Then came to find Su Shen.
Su Shen simply wrote on a whiteboard—
The core muscles are distributed around the center of gravity of the body.
Then strengthening the core muscles through training can allow the body to more effectively control the center of gravity.
This is easy to understand, so what’s next.
When running, the stability of the body's center of gravity is the key to maintaining linear movement. For example, transverse abdomen muscle contraction can increase intra-abdominal pressure, like a natural "belt", which stabilizes and supports the spine, thereby reducing left and right swings caused by center of gravity offset.
"Belt?" I was stunned.
Some don't know what this means?
"We all know that the core muscles play a key role in maintaining body balance. In the one-legged support stage, that is, there is a lot of one-legged support time during the sprint. A strong core can keep the body balanced during the dynamic process. For example, the abductor muscles such as the gluteus medius and gluteus minimus on the hips coordinate with the core muscles to stabilize the pelvis and prevent excessive pelvic tilt and body rolling."
"So……"
"The power chain integration." Su Shendao: "Human body movement follows the principle of the power chain, and the core is the key link of this power chain. A powerful core can optimize the power chain to ensure that the movement chain from the feet is stable and coordinated through the legs, hips, spine to the head. In this way, the whole body is like a train running along the track. Under the stable control of the core, all parts work together to keep running in a straight line."
"The power chain...integration???"
"Yes." Su Shen smiled and said, "Power chain integration."
"Big Niu, look at the composition and core position of the power chain." Su Shen drew a map on the whiteboard and said: "The power chain of the 100-meter sprint starts from the foot, goes upward through the calf, thigh, hip, through the core area, and then extends to the spine, upper limbs and head. The core is located in the center of the power chain, playing a key role in connecting the upper and lower levels. It connects the powerful propulsion generated by the lower limbs and the swinging power of the upper limbs, and is the hub for power transmission."
Nodded with rest.
He has also been on Ersha Island for so long.
I have also known a lot of basic muscle distribution and basic exercise science. I won’t know the same as the beginning, and I can only understand it at a glance.
"You're optimistic." Su Shen began to continue painting: "When starting, pushing the ground with both feet is the starting power of the power chain. When the athlete hears the starting signal, the leg muscles, quadriceps, hamstrings, etc., it contracts strongly, producing a pushing force behind and downward. At this time, this force is transmitted upward through the ankle, knee and hip joints."
"The hip muscles, gluteus maximus, hip flexors, etc. in the core muscles are quickly activated, gathering and initially integrating the forces from the lower limbs. At the same time, the core anterior muscle rectus abdomen muscles, posterior muscles, erection spinal muscles, etc. work together to stabilize the pelvis and spine, ensuring that the strength can be effectively transmitted upward along the central axis of the body. This integration avoids the dispersion of strength in the initial stage and lays the foundation for subsequent acceleration."
"This is the power activation and transmission."
"Then the moment of starting, the upper limbs also began to swing, and the arm movements were driven by the contraction of muscles such as the deltoid muscle and pectoralis major muscles. The core acts as a bridge connecting the upper and lower limbs to coordinate the swing of the upper limbs and the force of the pushing of the lower limbs. When the right arm swings forward, the core muscles such as the oblique abdomen and latissimus dorsi on the left side of the body will contract appropriately, coupling the force of the swing of the upper limbs with the force of the pushing of the lower limbs, forming a joint force to push the body forward and upward to quickly rush out. In this process, the stability and power transmission of the core ensure the accuracy and linearity of the starting direction."
"This is the linkage between the upper limbs and the core."
"As the running speed increases, the force of pushing the ground with the lower limbs gradually increases. The force generated by each push is transmitted upward through the bones and muscles of the leg. The muscles, transverse abdomen, polyfiss muscles, etc. in the core area bear and transmit this powerful force through equal length contraction. These muscles are like "shock absorbers", cushioning the force while ensuring that they are transmitted along the central axis of the power chain to prevent the force from being dispersed to both sides of the body."
"The core also plays a role in adjusting stride and stride frequency. This should be utilized. By controlling the rotation and forward angle of the pelvis, the core muscle group helps athletes find the best stride and stride frequency combination. When the core muscle coordinates the pelvis to tilt moderately, it can increase the effective work distance of the lower limbs, thereby increasing strides while maintaining body balance and linear acceleration."
"This step is called strength enhancement and conduction optimization."
Su Shen continued to draw: "Then during the acceleration process, all links of the power chain are closely coordinated. The rapid thrust of the lower limbs, the stable transmission of the core and the powerful swing of the upper limbs form an organic whole. The core is controlled by neuromuscles to keep the rhythm of the upper limbs consistent. After the core perceives the change in the frequency of the lower limbs, it will adjust the speed of the swing of the upper limbs to match it, ensuring that the body moves along a straight line during the acceleration process, and avoid left and right swings caused by incoordination of the upper and lower limbs."
"This can also accelerate the progression along the straight line during the process to avoid the swaying left and right caused by the incoordination of upper and lower limbs?" Lao Yi was stunned when he heard this and asked, "Can this still happen?"
"Of course." Su Shen smiled and said, "It only takes the coordinated promotion of all links of the power chain."
"But it's hard to maintain this." Lao Yi scratched his head and said.
"This is the point." Su Shendao, his hands were not idle, continued to draw: "The speed of the running stage has reached a high level on the way, and the stability of the power chain is crucial. The core muscles continue to work to maintain the body's posture. Muscles such as rectus abdomen, oblique abdomen and other muscles ensure the stability of the pelvis and spine in the horizontal and vertical directions by controlling the body's rolling and torsion. This allows the power chain to continuously and efficiently transmit strength, avoiding the loss of strength caused by changes in the body's posture."
"How to do that?"
"From a mechanical perspective, the body is subjected to a greater air resistance and ground reaction force when running on the way. The core stabilizes the power chain, so that the body maintains a good streamlined posture and reduces air resistance. At the same time, the ground reaction force is effectively converted into forward propulsion force to ensure that athletes can keep running at high speed in a straight line."
"Maintaining the stability and efficiency of the dynamic chain is the secret."
After listening to it, I felt that there were so many places to improve and optimize.
It's ridiculous that I thought...
It's over.
There is no way to continue to make progress.
"Then even during the running stage, the athlete's body may deviate slightly from the straight line, which may be caused by factors such as fatigue, wind, uneven tracks or slight changes in their own movements."
"What should I do? The core proprioceptors can perceive these changes keenly, and then activate the corresponding muscles for fine-tuning through the neuromuscular control system."
"Give me an example of you."
Su Shen made an action and asked Daniu: "Can you see what to do with this action? How to improve it?"
I thought about it after work and rest.
Shake your head.
His comprehension in this regard is indeed not as good as that of Zhang Peimeng and others.
But it doesn't matter.
Everyone has their own strengths.
Being able to understand with your body and learning during training is also another mode.
Su Shen will not deny any model.
"Look at it, big bull." Su Shen began to analyze it step by step: "When the body shifts slightly to the left, the core muscles on the right, such as the right gluteus medius, oblique abdomen, etc., will quickly contract, pulling the center of gravity of the body back to the straight line. What will happen?"
"In this way... can I ensure that my body runs more straight while running at high speed?"
"Opportune." Su Shen smiled and said, "Ensure the normal operation of the power chain and the straight running of the body."
"It's this function. Use the integration of your power chain to achieve the effect of correcting slight deviations and keeping a straight line."
"What's the end? Brother Tian, ​​I always can't do it well in the end, especially when my body starts to get tired, and I start unconsciously and fall into a sway." The problem of work and rest has been troubled for a long time, and I have been trying to find a way to break through but I can't break through it.
"This is normal." Su Shin said: "In the sprint stage, athletes need to exert their maximum strength to cross the finish line. At this time, the integration of the power chain reaches the highest strength. The core muscles will shrink with all their strength, closely combining the final explosive force of the lower limbs with the sprint swing force of the upper limbs."
"What should I do?"
Su Shen made an example: "Look, when you sprint, will you feel that your entire waist and abdomen are soft?"
"Well, it's a bit." Lao Yi said: "But I don't know how to solve it. The team tried a lot of methods, but the results were not good."
"Then try integrating the power chain, use muscles such as rectus abdominal muscle and erection spinal muscle to stabilize the spine and allow the body to withstand the huge impact of force during sprinting. At the same time, ensure that the force is transmitted along the straight line and achieve the final acceleration."
"Can this work?" Lao Yi said.
"Can do it." Su Shen nodded: "The core is crucial to maintain a straight sprint during the sprint stage. Due to fatigue and full-strength sprint, the body is more likely to have posture changes. The core prevents the body from swaying left and right or deviating from the straight line in the final stage by strengthening control of various parts of the body."
"As long as you work hard to integrate the power and maintain your posture, you can ensure a straight sprint in front of the finish line."
I digested these mind maps and Su Shen's words for a long time.
Su Shen didn't urge him either.
Waited for a long time.
Then he spoke slowly.
"But Brother Tian, ​​just looking at these principles, I still don't know how to do it."
"Am I too stupid?"
I feel a little embarrassed to talk about this.
He actually knew that Su Shen was a busy man.
He has too many things to do.
Most people on Ersha Island will not deliberately waste too much time. They already feel a little sad about their work and rest. Especially after Su Shen had already told him these things, he still couldn't figure it out and felt even more ashamed.
This chapter is not over, please click on the next page to continue reading! "Haha." Su Shen almost felt cute when he worked and rested. He smiled and said, "It's normal for you to not understand. It's normal for you not to know how to do it, because I haven't talked about how to do it yet."
I was stunned by work and rest.
Only then did I recover.
He had always felt that he had asked Su Shen to speak so much but couldn't understand it at all. He was so ashamed.
When I heard this, I immediately felt that my psychological burden was much more relaxed.
"I don't understand what it means?" Lao Yi asked after thinking about it.
"What I can't understand means..."
“It’s not just that you can’t understand.”
"He doesn't understand even if he changes his person."
"Why? Brother Gou Huan, Pei Meng and others can't understand?"
"It's definitely not OK just listen to it."
"Why?" I really don't understand why, because these people are people with great brains and strong comprehension in his heart.
"It's very simple..."
"I'll ask you, have you never heard of these things before?"
"yes."
"Did Randy not tell you and your team?"
"yes."
"Because."
"No one knows this thing except me."
"I just researched it and haven't published it yet."
"Then how could they know, you said?"
I was confused by work and rest.
Seeing this, Su Shen couldn't help it and said loudly: "I just used it myself. How about there are many unstable and bad places?"
"Do you dare to be a guinea pig with me?"
"I... dared." I also reminisced about it.
Nod your head hard.
In his eyes.
Even Su Shen dares.
What dares you not to?
Such a good opportunity.
If you miss it, you will be gone.
Must dare
You must dare to fail.
"That's good."
Su Shen chuckled softly, "Then I will tell you the remaining specific operation methods."
"But it's not that simple. You're very busy with winter training."
"Don't worry, Brother Tian." Lao Yi said seriously: "Even if I don't sleep, I will practice it well!"
"How can you not sleep? A good rest is the foundation for practicing well."
"Pay attention to the quality of training and don't delay rest time."
"good."
When I said this, I almost burst into tears.
...
Recalling this paragraph.
Standing at the starting line with work and rest.
Full of confidence.
Do you think you have some reservations?
Pei Meng.
