Chapter 2019 Power chain integration! I am the only person in the world who knows about it!
Testing continues.
Next comes the biggest highlight.
It’s also everyone’s favorite in recent years.
Because Su Shen and Zhao Haohuan did not participate, then Lao Yi and Zhang Peimeng became the focus of competition.
These two have always been at each other's throats.
It's tit-for-tat every time.
It's just that last year, Lao Yi lost a chance and ultimately failed to qualify for the individual events in the Olympics.
I can only watch Zhang Peimeng shining brightly on it.
Break through yourself.
This made him feel very sorry.
In addition, Lao Yi now feels that his "time is running out", even though he is the latest to enter the first team of Ersha Island.
But in fact, he is the oldest.
Do you think he will feel pressed for time?
In this urgent environment.
Lao Yi has already wound himself up.
I'm just waiting to fight Zhang Peimeng again this year.
While you are still at your peak.
Although this year's Olympics is not as cruel as last year's Olympics.
Ersha Island has already received a wild card.
Both people can go.
but.
Lao Yi also wanted to speak out for himself.
Back during the winter training, because Lao Yi didn't have a doctor like Hu Kai to help him, he also approached Su Shen privately.
Su Shen looked at him looking a little confused, smiled and gave him some analysis——
First of all, during work and leisure, we should focus more on strengthening the body.
It's been so long, it's too late to change it.
And it's not necessary.
It seems to Su Shen that this is a very suitable way for work and rest.
So how to solve it?
Su Shen raised a point here.
That's the problem with work and rest.
The running straightness is not enough.
This is also the reason why he can run with a long stride despite his height.
This problem naturally occurs.
Then targeted strengthening is necessary.
And at this point, we need to do it more meticulously and scientifically.
"Then how to do it?" Lao Yi asked Su Shen this question.
He himself knows this problem.
His team knows it too.
But I want to do better.
Easier said than done?
He has already optimized it once.
Optimize further to the extent of optimization.
Neither he nor his team has much confidence.
Then I came over to find Su Shen.
Su Shen simply wrote on a whiteboard——
The core muscles are distributed around the body's center of gravity.
Then strengthening the core muscles through training can allow the body to control the position of the center of gravity more effectively.
This is easy to understand, so what’s the next step?
When running, the stability of the body's center of gravity is the key to maintaining straight movement. For example, contraction of the transversus abdominis muscle can increase intra-abdominal pressure, acting like a natural "belt" to stabilize and support the spine, thereby reducing the risk of damage caused by the shift of the center of gravity.
The resulting left and right sway.
"Belt???" Lao Yi was stunned.
Some don’t know what this means?
"We all know that the core muscles play a key role in maintaining body balance. During the single-leg support phase, that is, there is a lot of single-foot support time during sprinting, a strong core can keep the body balanced during the dynamic process. For example,
The gluteus medius, gluteus minimus and other abductor muscles of the buttocks work with the core muscles to stabilize the pelvis when one leg is on the ground, preventing excessive pelvic tilt and body sideways tilt."
"So……"
"Kinetic chain integration." Su Shendao: "Human body movement follows the principle of kinetic chain, and the core is the key link of this kinetic chain. A strong core can optimize the kinetic chain, ensuring that force is exerted from the feet, through the legs, hips, spine, and
The kinetic chain of the head remains stable and coordinated. In this way, the entire 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."
"Power chain... integration???"
"Yes." Su Shen smiled and said, "Power chain integration."
"Daniu, look at the composition and core position of the kinetic chain." Su Shen drew a map on the whiteboard and said: "The kinetic chain of the 100-meter sprint starts from the feet, goes up through the calves, thighs, hips, and passes through
The core area extends to the spine, upper limbs and head. The core is located at the center of the power chain and plays a key role in connecting the upper limbs and the lower limbs. It connects the powerful propulsion force generated by the lower limbs and the swing assistance of the upper limbs, and is the hub of power transmission. "
Lao Yi nodded.
He also stayed on Ersha Island for so long.
I already know a lot about basic muscle distribution and basic sports science. It won’t be the same as at the beginning, where I can barely understand it at first glance.
"Look at it." Su Shen continued to draw: "When starting, pushing the ground with both feet is the starting force of the power chain. When the athlete hears the starting signal, the leg muscles, quadriceps, and hamstrings
Wait, strong contraction produces a pushing force backward and downward. At this time, this force is transmitted upward through the ankle joint, knee joint and hip joint."
"The hip muscles, gluteus maximus, hip flexors, etc. in the core muscle group are quickly activated to gather and initially integrate the power from the lower limbs. At the same time, the front muscles of the core, the rectus abdominis and the posterior muscles, the erector spine
The muscles and other muscles work together to stabilize the pelvis and spine, ensuring that force can be effectively transmitted upward along the central axis of the body. This integration avoids the dispersion of force in the initial stage and lays the foundation for subsequent acceleration."
"This is the activation and transmission of power."
"Then at the moment of starting, the upper limbs also begin to swing, and the contraction of the deltoid, pectoralis major and other muscles drives the arm movements. The core acts as a bridge connecting the upper and lower limbs, coordinating the power of the upper limb swing and the lower limb kicking. When the right arm swings forward,
, the obliques and latissimus dorsi on the left side of the body
When the core muscles will contract appropriately, the power of the swing of the upper limbs and the power of the lower limbs on the ground will be coupled together to form a combined force to push the body forward and upward quickly. In this process, the stability and power transmission of the core ensure the starting direction.
accuracy and linearity.”
"It's the upper body and core connection."
"As the running speed increases, the power of lower limbs pushing off the ground gradually increases. The force generated by each push on the ground is conducted upward through the bones and muscles of the legs. The muscles in the core area, transversus abdominis, multifidus, etc., through isometric contraction
To withstand and transmit this powerful force. These muscles are like "shock absorbers", buffering the force while ensuring that it is transmitted along the central axis of the power chain, preventing the force from being dispersed to both sides of the body."
This chapter is not over yet, please click on the next page to continue reading the exciting content! "The core also plays a role in regulating stride length and cadence. You should take advantage of this, Daniel. By controlling the rotation and forward tilt angle of the pelvis,
The core muscles help athletes find the best combination of stride length and stride frequency. When the core muscles coordinate the pelvis to tilt forward appropriately, they can increase the effective work distance of the lower limbs, thereby increasing the stride length while maintaining the body's balance and linear acceleration."
"This step is called strength enhancement and conduction optimization."
Su Shen went on to draw: "Then during the acceleration process, all links of the power chain work closely together. The rapid kicking and extension 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, making the upper limbs
The movement rhythm of the lower limbs remains consistent. After the core senses the change in the frequency of the lower limbs pushing on the ground, it will adjust the swing speed of the upper limbs to match it to ensure that the body moves in a straight line during acceleration and avoids swaying caused by uncoordinated upper and lower limbs.
.”
"This can also be used to advance in a straight line during acceleration to avoid swaying caused by uncoordinated upper and lower limbs?" Lao Yi was stunned when he heard this, and asked: "Can it still be like this?"
"Of course you can." Su Shen said with a smile: "It just needs to be coordinated by all links in the power chain."
"But it's hard to maintain like this," Lao Yi said, scratching his head.
"This is the key point." Su Shendao, his hands not idle, continued to draw: "The speed has reached a high level during the running stage, and the stability of the dynamic chain is crucial. The core muscles continue to work to maintain the posture of the body.
Stability. Muscles such as the rectus abdominis and oblique muscles ensure the stability of the pelvis and spine in the horizontal and vertical directions by controlling the side tilt and twist of the body. This allows the kinetic chain to transmit force continuously and efficiently, avoiding injuries caused by changes in body posture.
loss of strength.”
"Then how to do it?"
"From a mechanical point of view, the air resistance and ground reaction force experienced by the body during running are relatively large. By stabilizing the power chain, the core allows the body to maintain a good streamlined posture and reduce air resistance. At the same time, the ground reaction force is effectively converted into
The forward propulsion ensures that athletes can run at high speed in a straight line."
"Maintaining the stability and efficiency of the power chain is the secret."
After listening to it, I realized that there are so many areas that can be improved and optimized.
It's funny that I thought before...
It's over.
There is no way to continue to progress.
"Then even during the running phase, the athlete's body may deviate slightly from the straight line, which may be caused by factors such as fatigue, wind, uneven track or small changes in their own movements."
"So what should we do? The core proprioceptors can keenly sense these changes, and then activate the corresponding muscles to make fine adjustments through the neuromuscular control system."
"Let me give you an analogy."
Su Shen made a move and asked Daniel: "Can you see what should be done with this move? How can it be improved?"
Lao Yi thought for a while.
Shake his head.
In this regard, his understanding is indeed not as good as Zhang Peimeng's.
But it doesn't matter.
Everyone has their own strengths.
Being able to use your body to understand and learn during the training process is another model.
Su Shen will not deny any model.
"Look at it, Daniel." Su Shen started to help him analyze: "When the body shifts slightly to the left, the core muscles on the right side, such as the right gluteus medius, abdominal obliques, etc., will rapidly contract, pulling the body
If the center of gravity is pulled back to the straight line, what will happen?"
"This...can it ensure that the body runs in a straighter line during high-speed running?"
"My enemy." Su Shen said with a smile: "Ensure the normal operation of the power chain and the straight running of the body."
"That's it. Use the integration of your power chain to achieve the effect of correcting small deviations and maintaining a straight line."
"What about the end? Brother Tim, I always fail to do well in the end, especially when my body starts to get tired, and I start to sway unconsciously." This problem of work and rest has been bothering me for a long time, and I have been trying to find a way to break through it, but I can't make a breakthrough.
"This is normal." Su Shen said: "During the sprint phase, athletes need to use their maximum strength to cross the finish line. At this time, the integration of the power chain reaches the highest intensity. The core muscles will contract with all their strength, combining the final explosive power of the lower limbs with the upper limbs.
The thrust swing power is tightly combined.”
"Then what should be done."
Su Shen made an analogy: "Look, when you sprint, do you feel that your entire waist and abdomen are loose?"
"Well, it's a bit." Lao Yi said: "But I don't know how to solve it. The team has tried many methods, but the effect is not good."
"Then you try to integrate the kinetic chain and use muscles such as the rectus abdominis and erector spinae to exert more force to stabilize the spine so that the body can withstand the huge force impact during sprinting. At the same time, ensure that the force is transmitted in a straight direction.
Achieve final acceleration.”
"Is this possible?" Lao Yi asked.
"It can be done." Su Shen nodded and said: "The core is very important to maintain a straight sprint during the sprint phase. Due to fatigue and the state of full sprint, the body is more prone to posture changes. The core strengthens the control of various parts of the body to prevent the body from
In the final stage, it appears to sway side to side or deviate from the straight line.”
“As long as we fully integrate power and maintain posture, we can ensure a straight sprint to the finish line.”
Lao Yi spent a long time digesting these mind maps and what Su Shen had just said.
Su Shen didn't rush either.
Waited for a while.
Lao Yi slowly spoke.
"But Brother Tian, just looking at these principles, I still don't know how to do it."
"Am I too stupid?"
Lao Yi felt a little embarrassed when he said this.
He actually knew that Su Shen was a busy man.
He has too much to do.
Most people on Ersha Island would not deliberately waste too much of his time. Lao Yi already felt a little guilty. Especially after Su Shen had told him these things, he was still a little confused, and even more felt that
I feel ashamed.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "Haha." Su Shen almost felt that Lao Yi was cute. He smiled and said, "It's normal that you don't understand. You don't know why.
It’s normal to do it, because I haven’t explained how to do it yet.”
Lao Yi was stunned for a moment.
Only then did he regain his composure.
He had always felt that he was too embarrassed when he asked Su Shen to explain it in such detail but could not understand it at all.
After hearing this, I immediately felt that my psychological burden was relieved a lot.
"Then what do you mean you don't understand?" Lao Yi asked after thinking for a while.
"What I don't understand means..."
"It's not just that you don't understand."
"Anyone else wouldn't be able to understand."
"Why? Brother Gou Huan, Pei Meng and the others can't understand?"
"Just listening to it once is definitely not enough."
"Why?" Lao Yi really didn't understand why, because in his mind these people were all bright-minded people with strong comprehension abilities.
"It's very simple..."
"Let me 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 except me."
"I just researched it and haven't published it yet."
"Then how could they possibly know?"
Lao Yi was confused.
Su Shen couldn't help it when he saw this, and said loudly: "I have just used it myself. There may be many unstable and bad places, how about it?"
"Do you dare to be a guinea pig with me?"
"I...of course I dare." Lao Yi also thought about it.
Nod vigorously.
In his eyes.
Even Su Shen dares.
What don't you dare to do?
Such a good opportunity.
If you miss it, it will be gone.
Must dare
Dare to fail.
"That's good."
Su Shen chuckled and said: "Then I will tell you the remaining specific operation methods."
"But it's not that simple. You are very busy during winter training."
"Don't worry, Brother Tian." Lao Yi said seriously, "I have to practice it well even if I don't sleep!"
"How can you not sleep? A good rest is the foundation for good practice."
"Pay attention to the quality of training and don't waste your rest time."
"good."
Lao Yi almost burst into tears when he said this.
…
Think back to this paragraph.
Lao Yi stood at the starting line.
Full of confidence.
Do you think you are the only one who has reservations?
