Chapter 2020 Are you cheating on Su Shen? I can do it too!!!
Lao Yi vs Zhang Peimeng.
This is the focus of today's test.
Both of them fought with all their strength.
"Everyone take your place."
The two people looked at each other and said nothing.
Start working directly.
Over the years, the two have developed a tacit understanding in their fights.
"preparation."
Today’s surprises and superb skills come one after another.
Everyone is looking forward to it.
What will be the outcome of this final battle?
Is it just work and rest, or is Zhang Peimeng continuing to maintain his advantage?
Bang——
Gunfire rang out.
Two people rushed out at the same time.
In an instant, everyone's attention was attracted by these two people.
It takes energy.
In terms of initiating reactions, Zhang Peimeng is naturally better. Needless to say, having the talent to initiate reactions is one of Zhang Peimeng's original talents.
Even Su Shen carries out scientific training in various aspects.
It doesn't even reach this level.
He can hold his head down in this place.
throughout the history of Asia.
Maybe it’s just the gun-crazy guy, Ryota Yamagata.
The first step is to go out and land.
Standard four points and one line.
Ankles, knees, hips and shoulders.
Integrate into one.
first step.
The tibialis posterior muscle is the first to exert force. When it contracts, it can help the ankle to produce internal rotation. This is like installing a precise steering device on the ankle, laying the foundation for the reasonable transmission of subsequent force and the smoothness of foot movements.
So that the first step can have the appropriate angle and direction of force.
The key lies in the preparation of force at the ankle.
Zhang Peimeng did this three points better than last year.
This shows that even though he made a breakthrough last year, he still hasn't slacked off at all. After so many years on Ersha Island, he is no longer the same person in the original timeline.
Things like being careless, having fun, and enjoying life are no longer relevant to him now.
He has been completely polished into a professional-level world athlete with a tough and steady mind.
At the same time, the peroneus longus muscle contracts to help the ankle produce external rotation, and cooperates with the internal rotation of the tibialis posterior muscle to allow the ankle to flexibly adjust its posture and adapt to the instantaneous force changes and body balance needs when starting.
Then, the flexor digitorum longus muscle is also contracting at this time. Its important role is to maintain the shape of the arch and stabilize the foot structure, just like building a stable "foundation" to ensure that force can be effectively transmitted upward from the sole of the foot.
As for the situation where strength is lost or the foot support is unstable.
Su Shen looked at it and nodded silently.
The function of the first step is - the ankle movement and stability at the beginning of the start. It is the starting point for subsequent acceleration. Good ankle force generation and posture control can make a good start for the entire starting acceleration process and transfer the subsequent force to the legs.
Create favorable conditions in other parts of the department.
Zhang Peimeng did a very good job.
Even how he looks.
The same is true.
Step two.
The gastrocnemius begins to play a key role.
It contracts to provide strong propulsion force for the ankle. This force pushes the body to move forward quickly, as if a powerful "booster" is installed on the body.
On the basis that the tibialis posterior, peroneus longus, and flexor digitorum longus muscles have prepared the ankle, the gastrocnemius further amplifies and converts the force into forward propulsion, allowing the speed to be quickly increased and the start from the start to be achieved.
The gradual transition from state to accelerated state.
In the traditional four golden steps, the second step requires enough strength to get the body out of stillness and quickly gain forward speed. The propulsive force provided by the gastrocnemius is the key to achieving this goal. It takes over the previous
The force prepared by the various muscle groups at the ankle is transformed into actual acceleration power, pushing the body to accelerate forward in just a few meters.
Step three.
With the ankle as the center, the force generated by the four major muscle groups at the ankle begins to spread and stimulate the surrounding four major muscle groups.
At this point, the quadriceps muscles begin to contract.
The quadriceps femoris is the most important extensor muscle of the knee joint. Its main function is to straighten the knee joint. During active isometric contraction, it can help stabilize and protect the knee joint to ensure that the knee joint does not appear during high-speed running.
Unnecessary shaking or uneven force ensures the forward continuity and stability of the body.
Starting from the third step, the body's requirements for the stability of the knee joint are getting higher and higher, and the quadriceps muscles stabilize the knee joint through isometric contraction, allowing the body to maintain a good force-generating posture during continuous acceleration and avoid knee joints.
Joint instability may lead to strength loss or risk of injury, thus ensuring further speed improvement.
Step 4.
The eccentric contraction function of the quadriceps becomes particularly important. When it contracts eccentrically, it can control the speed of the body's descent.
This helps to adjust the body posture when the acceleration is about to begin, to better cope with the connection between landing and kicking off each step, and to ensure that every force exerted can be efficiently converted into forward momentum.
Let the speed increase more smoothly in the final stage of startup.
It can be seen that Zhang Peimeng should have strengthened his quadriceps eccentric contraction ability through winter training.
This can accurately control the body posture and release force during the sprint phase. The eccentric contraction ability of the quadriceps can exactly meet this demand, so that the entire first 10 meters of the start can be ended in the best condition, helping Zhang Peimeng to start in the best condition.
phase to gain the greatest possible speed advantage.
Zhang Peimeng's golden four steps fully utilize the four-point connection. Compared with when he first mastered it last year,
It is more based on the scientific laws of human body movement. From the feet to the legs, each muscle group functions in sequence and cooperates with each other.
Together, they push the body to quickly enter a high-speed sprint state from a standstill.
Every stage is indispensable.
The force-generating characteristics and functions of each muscle group are closely related to the efficiency and quality of starting acceleration.
Zhang Peimeng's character has indeed been tempered.
will be stronger.
His talent.
Never have any doubt.
When the wind speed is not too high, you can bring out your best on the stage of the World Series and almost open for 10 seconds. This is already a traditional system, although the water and wood system is not so completely traditional, but in
Comparing it with the real scientific system, it still seems not advanced enough.
Even with this background, he is still one of the strongest performers in China many years later, even no worse than those young people who have undergone scientific training.
Just hone your character.
Zhang Peimeng’s talent.
Su Shen really never worries much.
Then cooperate with your own unique second gear start.
Zhang Peimeng is ten meters tall.
It is bound to put aside a lot of work and rest!
Work and Yi will definitely be suppressed this year and completely thrown away!
that is……
the development of things.
It was not as beautiful as Zhang Peimeng thought.
It's not as beautiful as Hu Kai thought.
Because of this voice behind me...
Remind him all the time.
People are right behind you.
He was not thrown away quickly.
"How could it be?" Hu Kai looked at it, his expression slightly frozen. He knew that Zhang Peimeng had improved again this year.
Startup has never been Lai Yi’s strong point.
How is it possible that Zhang Peimeng has made great progress here this year, but still hasn't given up, working too much and resting too much?
This is so unreasonable.
In fact, there is nothing unreasonable.
If you still remember the optimization done by Work and Yi last year, you will know. Last year, Work and Yi actually slightly suppressed the rhythm of the entire future for the sake of the overall rhythm and distribution of work and Yi. This is also to allow for better top speed and top speed maintenance.
, the latter has more room for impact.
Bang, bang, bang, bang, bang.
Bang, bang, bang, bang, bang.
Acceleration zone.
Zhang Pei started driving at a fierce speed and started more powerfully. Of course, this place will have faster acceleration and enter the acceleration zone.
He didn't know how to work and rest.
He doesn't care how.
Because starting is just a beginning for yourself.
Your start will become more powerful, and you will definitely make your acceleration zone run faster in the future.
Sprinting is a holistic event.
If the front is faster, it will also have an impact on the back.
It's not something that is divided.
My own accelerated running will definitely suppress my fatigue.
Hu Kai thinks so too.
Last year, when Zhang Peimeng and Lao Yi faced off in the winter test, Lao Yi followed him because he was distracted. This time, Zhang Peimeng did not make this mistake again.
He took the game seriously the whole time.
Concentrate on completing your own technical processes.
But ten meters later.
Another ten meters.
Bang, bang, bang, bang, bang.
Bang, bang, bang, bang, bang.
I have been running very smoothly, and I feel worthy of what I want.
But.
The sound of spikes behind me.
It doesn't seem to have reduced much either.
Zhang Peimeng frowned slightly.
Even when running at high speed, faced with such a situation, his expression began to operate uncontrollably.
"Why? It's wrong, it shouldn't be."
Hu Kai saw that the start was over, and Zhang Peimeng failed to establish the advantage he imagined.
Then let’s go to the acceleration zone.
You can also create an acceleration zone.
The accelerator area has not been established yet.
Hu Kai also felt a little stunned.
He clearly felt it.
What is the technology of never stopping work and rest?
It's not like Zhang Peimeng, who he led, who made a lot of technical improvements and overcame various technical difficulties.
Lao Yi couldn't even connect the four points.
But there's a problem.
Many people actually fail to connect the four points.
That doesn't stop him from getting good results.
Look at the players on Team USA.
Aren’t all of them connected by three points?
Why can people run so fast?
In the development of technology, there are naturally advantages and disadvantages, advanced and unadvanced. But for the people who use it, there is a difference between what is suitable and what is not suitable, between what is suitable and what is not suitable, between what is used well and what is not.
Bad difference.
Rest here.
There is no technical stream.
Of course, the so-called "not following the technical flow" here means not passing the obvious technical hurdles.
It's not that he can run so fast now without technological advancement.
Control over the body.
It is a basic skill in any competitive sport.
As long as this basic technology is done well.
It can also reach a certain height.
Technology is prioritized, but application is not.
Which one can develop his or her body to its limits?
Which one can achieve better results and is more comfortable to use?
Then which one can be used.
What's more, I have already reached this age.
There's nothing you can't try.
Last year, we used a strong core to support and counteract the excessive flexion of the rectus thigh, especially when the iliopsoas muscle is stressed too much and too frequently, and the hip flexion function will be reduced. At this time, the rectus femoris will overcompensate for flexion.
Hip, as time goes by, there is an obvious muscle pulling on the front of the thigh, which will cause the stretch reaction to slide down and down, almost being blocked.
It even enhances the body's stretch response to increase the body's driving force.
Is it the same this year?
Of course not.
What he wants to take out now is what Su Shen is using now.
It’s called power chain integration!
"As the central structure of the body, the stability of the pelvis directly affects running posture. The gluteus maximus, gluteus medius, gluteus minimus and pelvic floor muscles in the core muscle group work together to stabilize the pelvis. The gluteus medius and minimus are
This muscle is mainly responsible for controlling the lateral balance of the pelvis when supporting on one foot, preventing the pelvis from tilting excessively to one side and avoiding Trendelenburg gait."
"This kind of gait is an abnormal gait in which the pelvis is tilted and the body is swaying from side to side due to weakness of the abductor muscles. Athletes happen to have this problem due to too much training intensity or too much sprinting, which leads to weakness in this area.
Condition."
"First we have to get rid of this gait."
“During running, especially when running in curves or when accelerating and changing directions, whether the pelvis is stable or not has a great influence on keeping the body running in a straight line. A stable pelvis can make the lower limbs exert more reasonable force and ensure that the body advances in the expected straight direction.
.”
"How?"
"The first thing is to balance on one foot."
"During sprinting, the single-leg support phase is a moment when the body's balance is easily broken. At this time, the core muscles need to adjust quickly to maintain balance."
This chapter is not finished yet, please click on the next page to continue reading the exciting content!...
This is what Lao Yi is here. Starting from balancing on one foot, you can see that the moment one foot touches the ground, the ground reaction force transmitted from the sole of the foot begins to be transmitted to the core area and core muscles through the legs and hips.
Then through isometric contraction, a contraction method in which the muscle length remains unchanged but the tension increases, this force is buffered and the body posture is adjusted so that the center of gravity falls stably above the supporting foot.
Then use the three joints of the ankle, knee, and hip as support points, and rely on core control to keep the body in a straight line during the short period of single-leg support and avoid tipping to the left and right sides.
So what are the prerequisites or preconditions for doing this?
Of course... strong core capabilities.
When excellent sprinters run at high speeds, although the support time of one foot is short, their body will hardly sway significantly due to their strong core balance ability.
This is the first step to reduction.
Why can't others?
It is because others do not have such core abilities, so Su Shen told them that it is meaningless to ask them to do it. The only people in Ersha Island who can do this are those who have perfected the quality of their movements every time and never complained.
It's called tired work and rest.
Of course there are more advanced ones.
It's called dynamic balance adjustment.
Let’s not mention this for now.
Afterwards, Yi Yi coordinated the upper and lower limbs and began to change the power transmission path.
In sprinting, the swing of the upper limbs and the kicking of the lower limbs are two key movements that cooperate with each other. The core muscles are between the two and play a connecting role.
Everyone knows this.
The question is how to optimize it to a straight line?
This is how work and rest work. From the perspective of the lower limbs, when the leg muscles, quadriceps, hamstrings, and triceps exert force to push off the ground, the force generated will be transmitted upward along the bones and pass through the hips.
.
At this time, the hip flexors, extensors, etc. in the core muscle group will participate to integrate and regulate the force, and then continue to transmit it upward to the spine and trunk.
Then the force generated by the swing of the upper limbs will also be transferred through the core area.
Then, when swinging the arms, the strength of the latissimus dorsi, pectoralis major, etc. merges with the force of the lower limbs through the core to form a resultant force around the central axis of the body.
Push your body forward in a straight line to accelerate!
So what are the prerequisites for doing this?
It is still an extremely powerful and high-quality steel core.
If the core strength is insufficient, there will be a "break point" in this power transmission.
As a result, the strength is dispersed and the body posture becomes easily unbalanced.
Swaying from side to side in an attempt to regain balance.
There is nothing wrong with what Lao Yi does here.
It was exactly as Su Shen expected.
This is for work and leisure.
Not a problem at all.
Secondly, adopt the muscle synergy mode.
Originally, there is a specific synergistic contraction pattern between the core muscles and the muscles of the upper and lower limbs.
Take the just starting stage as an example.
After hearing the gunshot, Yi Yi's lower limbs quickly stretch. At the same time, the rectus abdominis and oblique muscles in the core muscle group will contract synergistically with the deltoid muscles, biceps brachii, etc. of the upper limbs.
Allows the body to quickly get out of a static state.
And rush forward in a straight line.
acceleration stage.
As cadence and stride length stabilize, this synergistic contraction pattern continues to function.
As long as you maintain the balanced output and reasonable transmission of force in all parts of the body, you can avoid breaking the body's motion state due to too much or too little strength in a certain part.
You can still maintain a better straight line of motion!
These specific body controls function.
Each item points directly to the core issues that need to be improved in work and rest.
Allowing him to reduce left and right deviations during running.
Further maintain the straight line of motion.
As long as you run sprints, even if you are a sports student, you should know that the more you swing from side to side, the greater your actual running distance will be.
The best position is always a straight line.
The shortest distance is always a straight line.
How to make your body better stable on this straight line?
You can get the best sprint route and distance for yourself.
Sprinting.
Especially at the elite level.
The battle is 0.01 seconds.
Lao Yi made physical changes to this place.
Make his sprinting route straighter.
Reduces left and right swing waste.
Naturally.
The speed increased.
that's why.
Zhang Peimeng obviously started to react faster.
It is clear that the four-point and one-line technology is more accurate than last year.
But it's still in the startup and acceleration area.
There is no reason to get rid of work and rest.
This guy...
affim.
I found Su Shen!
This was Zhang Peimeng's first instinct after reacting.
Why would he think so.
Because he thinks that if it were him,
I encountered these and got stuck.
Wouldn’t he also use this trick?
Have a question?
Find Su Shen.
so……
You thought.
You just started the small stove.
Are you the only one who would ask the GM for the password?
