The Su God of the Reopening of the Sports Arena

Chapter 2261: Frontal Kill! The name of lightning... is red!!!

Actually behind.

at this moment.

They all became spectators in front.

Even these players who are competing.

In fact, they all want to know what the outcome of this game will be.

Who will have the last laugh between the two lightning bolts?
It's Bolt copying Eugene's legend.

Or maybe Suarez finally worked hard this season and defeated Bolt.

Take the first blood of this season.

To gain a victory before the Battle of Moscow.

The last five meters.

Su Shen is also not vague here.

The body's functions have indeed reached a limit.

But now he has another system to assist him.

All the training throughout the season is for now.

It allows you to apply this system in actual combat.

Give yourself an additional layer of the most powerful plug-in.

otherwise.

A monster like Bolt.

Don't give yourself some cheats.

It seems to be difficult to deal with.

Even if it's using science to cheat.

That's also a hang.

Usain.

Please enjoy it.

Today's shot.

It will be a turning point between the two of us.

starting today.

The winning rate between you and me will no longer be one-sided!
By this time.

Su Shen's neck was a little stiff.

Your neck determines the positioning of your head while you run.

It also has a huge impact on the performance of short-distance running.

If you don't have a brain.

Then you go faster.

It can't be used.

Just fall down.

Embarrassed.

Compensation strategies for neck muscle imbalance!
When the neck muscles, such as the sternocleidomastoid and splenius cervicis, become out of control due to fatigue, Su Shen's parallel control system will link the core and upper limbs to compensate.

First, activate the deep neck flexors, longus capitis and longus colli, to stabilize the cervical curvature and ensure that the head is in a neutral position.

At the same time, the rectus abdominis and erector spinae muscles of the trunk enhance their coordinated contraction, helping to maintain head balance by adjusting the forward tilt angle of the trunk.

In addition, the arm swing muscles of the contralateral upper limb will synchronously adjust the force intensity, using the principle of force balance to offset the torque generated by the neck imbalance. When the strength of the neck muscles decreases by 20%, the abnormal swing amplitude of the head can still be controlled within 3°, ensuring the smoothness of the overall power chain.

such.

The power chain has not completely collapsed.

And put it before.

When it reaches this position, the power chain has basically collapsed.

And it was broken beyond recognition.

Even the last time of 9 seconds was the same.

The last 10 meters completely collapsed.

otherwise.

No particularly good technology is required.

Just need to go along smoothly.

That is.

New realm.

Su Shen himself knows this.

It's already his second life, and he knows this better.

This problem is a stubborn problem in his mind.

I've always wanted to find a way to overcome this.

If we say Bolt's biggest problem is the first 10 meters of the start.

So that’s Su Shen’s biggest problem.

It’s the last ten meters.

This problem can be said to be a chronic disease that Su Shen has in any game.

Just get this problem solved.

He can make great improvements in any game.

This life.

this problem.

It's time to solve this problem.

At least it should be improved.

A problem that has not been improved after two lifetimes.

Su Shen finally waited for the opportunity to improve.

That is.

just now!

Lack of biceps strength?

When the biceps femoris fatigues during the back-pedal phase of running, resulting in a decrease in the ability to flex the knee and extend the hip…

The parallel control path quickly initiates compensation.

Compensation is turned on.

On the one hand, the semitendinosus and semimembranosus muscles are activated to enhance their contraction, share the knee flexion task of the biceps femoris, and maintain the speed and amplitude of the calf's posterior swing.

On the other hand, the gluteus maximus and erector spinae muscles work together to compensate for the loss of lower limb posterior push-off force by strengthening the hip extension and forward tilt of the trunk.

When the biceps femoris force decreases by 30%, this compensatory mechanism can control the decrease in back-pedaling efficiency to within 12%.

enough?

not enough.

The scalene muscle function is weakened again at this time.

If the scalene muscles become fatigued, they will not be able to effectively assist the inhalation action.

But now.

The parallel control system is activated.

The other respiratory muscles compensate.

First, the contraction intensity of the diaphragm increases, and the volume of the chest cavity is increased by increasing the amplitude of descent; at the same time, auxiliary respiratory muscles such as the pectoralis major and pectoralis minor participate in the coordinated contraction to help lift the ribs and expand the chest cavity.

In addition, the rectus abdominis and external oblique muscles strengthen their contraction during the exhalation phase, speeding up the discharge of waste gas and ensuring efficient gas exchange during running.

Even if the scalene muscle function decreases by 40%, this compensatory mechanism can still maintain respiratory rate fluctuations within 15% of the normal state.

enough?

not enough.

Tibialis anterior muscle strength is insufficient.

Nothing.

Keep doing him.

Parallel control paths continue to provide a safety net.

When the tibialis anterior muscle is unable to effectively complete the dorsiflexion of the foot.

This will cause the cushioning ability of Su Shen's feet to decrease when he lands.

Parallel control path, at this time, multi-joint linkage will be started.

After linkage.

The early activation of the peroneus longus and peroneus brevis will assist in completing the dorsiflexion of the foot while reducing the burden on the tibialis anterior muscle.

The knee and hip joints increase their flexion angle, which also prolongs the cushioning time and reduces the impact force on the ground.

In addition, the Su Shen plantar intrinsic muscles enhance contraction and further buffer pressure by adjusting the elasticity of the arch.

When the tibialis anterior muscle force decreases by 35%, this compensatory strategy can reduce the peak impact force at landing by 20%.

Quadratus lumborum synergism insufficiency?
If the quadratus lumborum muscle is fatigued, it will lead to a decrease in the lateral flexion and stability of the trunk, and the parallel control mechanism will coordinate multiple muscle groups to supplement their functions.

The transverse abdominal muscles and internal oblique muscles increase their contraction, maintaining trunk stability by increasing abdominal pressure.

At the same time, the erector spinae and gluteus medius muscles on the opposite side work together to adjust the pelvic tilt angle and correct the trunk deviation.

In addition, the upper limb arm swing muscles synchronously adjust the amplitude and speed, using the principle of force couple balance to help maintain body balance.

Flexor pollicis longus weakness?

When the flexor hallucis longus is unable to effectively complete the big toe grip, the parallel control pathway will activate other toe muscles and calf muscles.

The flexor digitorum longus and lumbrical muscles increase their contraction, replacing the flexor hallucis longus to complete the gripping action and maintain effective contact between the forefoot and the ground.

The calf triceps work in advance to enhance the plantar flexion of the ankle joint and compensate for the loss of propulsion caused by insufficient grip of the big toe.

The tibialis posterior muscles contract synergistically to maintain arch height and stability.

When the force of the flexor pollicis longus decreases by 40%, this compensatory mechanism can still keep the push-off efficiency from decreasing by no more than 18%.

enough?

not enough.

Su Shen is here.

It is to compete with Bolt.

previous games.

It’s okay to lose.

But this one.

He came here to win.

Because of preparation.

Already in place.

It's time to produce results.

Iliopsoas muscle weakness?
When the iliopsoas muscle fatigues during the forward swing phase of running, causing the hip joint to have reduced flexion ability.

Su Shen's parallel control system quickly launches a multi-level compensation strategy.

First, the sartorius and rectus femoris assist in the forward swing of the thigh by increasing the frequency and intensity of contraction, ensuring that the stride length is not significantly affected.

Then the tensor fasciae latae and the anterior bundle of the gluteus medius work together to further enhance the forward driving force of the lower limbs by increasing the anterior tilt angle of the pelvis.

In addition, in order to maintain the continuity of the kinetic chain between the trunk and lower limbs, the contralateral erector spinae and latissimus dorsi muscles adjust their tension synchronously to optimize the trunk posture through the reverse pulling effect.

When the power of the iliopsoas muscle decreases by 35%, this compensatory mechanism can control the step frequency fluctuation within 8%, while keeping the forward swing efficiency reduction within 15%.

Decreased levator scapulae function? Continue to use parallel control mechanisms.

If the levator scapulae muscles cannot effectively stabilize the scapula due to fatigue, the arm swing efficiency will be reduced.

Parallel control pathways will activate the co-compensatory mechanisms of the upper limbs and trunk.

The contraction force of the upper trapezius and rhomboid muscles is enhanced, maintaining shoulder stability by elevating and adducting the scapula.

The serratus anterior contracts strongly, helping to protrude the scapula to optimize the arm swing path.

In addition, the pectoralis minor and subclavius ​​muscles participate in synergistic action, reducing the compensatory tension of the shoulder by adjusting the micro-movement of the sternoclavicular joint. In order to maintain the overall dynamic balance, the ipsilateral external oblique muscles and latissimus dorsi increase the frequency of cross-contraction during the arm swing process, using the trunk rotation force to assist the upper limb movement.

When the levator scapulae function decreases by 40%, this compensatory system can control the arm swing power loss within 12%.

It can ensure the efficiency of energy transfer when running.

That last little bit of extra energy.

Will bring it.

Different effects.

Piriformis dyssynergia?
When the piriformis muscle becomes fatigued, resulting in insufficient external rotation and stabilization of the hip joint.

The parallel control system initiates a multi-dimensional compensation scheme.

The posterior bundle of the gluteus minimus and the obturator internus muscle strengthen their contraction, sharing the external rotation function of the piriformis muscle and preventing the lower limbs from buckling inward and affecting the running posture.

The quadratus femoris and gemelli muscles work together to strengthen the stability of the proximal femur and reduce the risk of abnormal knee torsion.

In addition, in order to maintain the coordination of the pelvis-lower limb power chain, the contralateral quadratus lumborum and transverse abdominal muscles dynamically adjust their tension, and Su Shen corrects gait deviation by controlling the pelvic tilt angle.

Biomechanical analysis shows that when the piriformis muscle force decreases by 30%, this compensatory mechanism can control the abnormal rotation angle of the hip joint within 3° and increase the speed maintenance.

Weak extensor digitorum brevis?

The extensor digitorum brevis muscle cannot effectively complete the toe dorsiflexion and gripping movements due to fatigue.

Nothing.

The parallel control pathway will activate the joint compensation mechanism of the foot and lower leg.

The extensor digitorum longus and peroneus tertiary muscles exert force in advance to enhance the dorsiflexion of the foot and ensure that the forefoot leaves the ground smoothly.

At the same time, the interosseous muscles and lumbrical muscles strengthen their contraction and maintain grip stability by adjusting the angle of the toe joints.

To compensate for the loss of propulsion force, the anterior calf muscles and the posterior tibialis muscles form an antagonistic contraction, optimizing the ground pushing efficiency by adjusting the elasticity of the arch.

When the force of the extensor digitorum brevis decreases by 45%, this compensatory strategy can control the reduction in peak push-off force to within 18%, while keeping the step frequency fluctuation within 10%.

Then comes the preparation work for pressing the line.

Compensatory strategies for sternocleidomastoid muscle fatigue.

Su Shen adopts the parallel control system to activate the overall compensatory mechanism mode of the head-neck-trunk when the sternocleidomastoid muscle is unable to effectively participate in the stabilization of the head and neck due to fatigue.

The splenius and cervicis muscles increase their contraction, maintaining a stable line of sight by extending and flexing the head.

The scalene muscles and levator scapulae muscles work together to adjust tension and help maintain the physiological curvature of the cervical spine.

In addition, to avoid overcompensation of the neck, the deep cervical flexors work in conjunction with the rectus abdominis muscles to indirectly reduce the load on the neck by increasing abdominal pressure and reacting to the trunk.

When the function of the sternocleidomastoid muscle decreases by 35%, this compensatory mechanism can control the abnormal head deviation angle within 2.5°, ensuring the accuracy of visual positioning and posture control during running.

And this is all pressure line.

A very critical point.

Why is the final choice the compensation of the sternocleidomastoid muscle?
The sprint finish line action seems to be completed in an instant, but it is actually a highly coordinated and complex movement process.

From a biomechanical perspective, the essence of sprinting is to precisely control the body's posture and the movements of various parts of the body so that a specific part of the torso, usually the chest, touches the finish line first at the fastest speed.

Chen Juan’s big breasts were a killer before.

Is typical.

The second is.

When pressing the line, the fatigue level is already very high.

When approaching the finish line, you need to quickly adjust the torso angle from the forward leaning state to a more horizontal posture so that the chest can reach the finish line in the shortest way. This process requires the core muscles, neck muscles, etc. to work together to maintain body balance and posture stability.

In addition, you still need to maintain a relatively high running speed at the moment of crossing the line to avoid a sharp drop in speed due to movement adjustments.

This relies on the continuous exertion of the lower limb muscles and the upper limb swing to assist in maintaining speed.

It is very important to accurately judge the timing of the line. If you press the line too early or too late, it will affect the final score. You need to rely on good spatial perception and movement coordination to complete the line action in the best position of the body.

These are known as the three elements of pressure.

They are control posture.

Speed ​​maintained.

And the timing of action.

Want to be satisfied.

I am currently in a state of high fatigue.

This is the most important step to take.

The sternocleidomastoid muscle is an important muscle in the neck. Its main functions include:
1. Head movement control: Unilateral contraction can make the head bend to the same side and turn to the opposite side, and bilateral contraction can make the head tilt back. During sprinting, the contraction and relaxation of the sternocleidomastoid muscle can maintain a stable head posture, ensure that the line of sight is forward, and provide correct visual guidance for running.

2. Neck stability: The sternocleidomastoid muscle works with other neck muscles to maintain the physiological curvature and stability of the cervical spine, prevent excessive shaking of the neck due to inertia and other factors during high-speed movement, and reduce energy loss.

3. Participation in the power chain: There is a mechanical relationship between the sternocleidomastoid muscle and the muscles of the trunk. The force generated by its contraction can be transmitted to the trunk through the neck, and to a certain extent, it participates in the overall power balance and movement coordination of the body.

For example, during the arm swing process of running, the change in tension of the sternocleidomastoid muscle helps maintain the relative stability of the head and torso, ensuring smooth upper limb movements.

In high-intensity sprint competitions, the sternocleidomastoid muscle is prone to fatigue due to continuous load. When the sternocleidomastoid muscle is fatigued, its normal function will be affected, which will in turn have a series of adverse effects on the sprint line.

For example, the head posture is out of control: the fatigue of the sternocleidomastoid muscle leads to a decrease in its ability to control head movement, and it may be difficult to maintain a stable head posture. When approaching the finish line, the head may shake or deviate involuntarily, affecting the accuracy of the line of sight, making it difficult for athletes to accurately judge the position of the finish line and miss the best time to cross the line.

For example, the stability of the neck is reduced: the stability of the neck depends on the coordinated action of multiple muscles such as the sternocleidomastoid muscle. After the sternocleidomastoid muscle is fatigued, the stability of the neck is reduced. During the process of adjusting the body posture when pressing the line, it may cause excessive flexion and extension or lateral tilt of the neck, interfering with the adjustment of the overall posture of the torso, making it impossible for the chest to touch the finish line at the most favorable angle and position.

For example, the power chain conduction is blocked: the sternocleidomastoid muscle is involved in the body's power chain, and its fatigue will destroy the integrity and smoothness of the power chain. When pressing the line, the power transmission of the upper limb swing may be blocked due to the poor condition of the neck muscles, affecting the overall coordination and speed maintenance ability of the body, causing Su Shen to slow down at the moment of pressing the line, reducing the efficiency of pressing the line.

These three points coincide with the main functions of the sternocleidomastoid muscle mentioned above.

So finally.

It’s the specific operation.

The last ten meters or even five meters.

The splenius capitis and splenius cervicis muscles strengthen their contraction, maintaining a stable line of sight by extending and flexing the head.

The splenius capitis and splenius cervicis are important muscles at the back of the neck. Their contraction can provide additional force to control the movement of the head when the sternocleidomastoid muscle is insufficient.

During a sprint, you need to keep an eye on the finish line. The compensatory contraction of these two muscles can ensure that the head does not shake randomly due to fatigue of the sternocleidomastoid muscles, ensuring that your sight always accurately locks on the finish line, providing a guarantee for accurately judging the timing of crossing the finish line.

The scalene muscles and levator scapulae muscles work together to adjust tension and help maintain the physiological curvature of the cervical spine.

The scalene muscles are mainly involved in the lateral flexion and flexion of the neck, while the levator scapulae can lift the shoulder blade and assist in lateral flexion of the neck. When the sternocleidomastoid muscle is fatigued, these two muscles compensate for the deficiency of the sternocleidomastoid muscle in maintaining cervical stability by adjusting the tension.

Moreover, before preparing to press the line, the stable physiological curvature of the cervical spine helps to maintain the relative position of the head and torso, allowing Su Shen to adjust the torso posture more smoothly and complete the pressing line action at the appropriate angle.

The last step is to mobilize the linkage between the deep cervical flexors and the rectus abdominis!
To avoid overcompensation of the neck, the deep cervical flexors work in conjunction with the rectus abdominis to indirectly reduce the load on the neck by increasing abdominal pressure and reacting to the trunk.

The deep cervical flexors stabilize the anterior cervical spine, while the rectus abdominis increases intra-abdominal pressure when contracted.

During the sprint, this linkage mechanism can optimize the body's overall mechanical structure. On the one hand, the increased abdominal pressure can provide support for the trunk, helping Su Shen to better control his body posture.

On the other hand, reducing the load on the neck can avoid stiff movements caused by excessive neck force, allowing the head and neck to maintain a certain degree of flexibility during the compensation process, making it easier to fine-tune the pressing action at the last moment.

The final details.

The last ten meters.

Su Shen knew that it was the key to his success or failure.

The goal is just ahead.

I can already see clearly.

Su God!

Improve your sight stability!
Su God!

Optimized torso posture adjustment!
Su God!

Maintain body coordination!!!
Ninety-six meters.

Ninety-seven meters.

Ninety-eight meters.

By this time Bolt was also approaching.

The last 10 meters should have been where he successfully overtook.

却。

Suddenly, it felt like I was taking a breath.

The whole person paused for half a second.

Bolt was also surprised.

He doesn't understand.

Why in the end...

Such a situation arises.

in this situation.

It was completely beyond his expectations.

Therefore, I could only look at Su Shen.

Look, it’s still ahead.

The red silhouette so close at hand.

Open your hands.

Swing your arms.

Whipping.

Bury your head.

Cross the finish line.

Scientific wind control technology.

It was also pushed to the maximum value at this moment.

Try your best to the maximum.

call------------

There was a gust of wind blowing past my ears.

And this time.

Unlike Eugene.

It is not at the last node.

By a dark shadow.

Flashed past.

So……

Su Shen already felt it when he crossed the finish line.

Then there was a huge cheer from the audience.

Includes live commentator.

At the mountaintop stadium in Lausanne.

Shouted out a string of numbers that he couldn't believe -

"9..."

“9.47??????????”

“9.47!!!!!!!!!!!!!!!!!!!!!”

"World...world record!"

“A new world record is born!!!”

"It's Sue!"

“CREATE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!”

ps: A new world record is born! ! ! ! ! ! ! ! !

The first effective 9.50 breakthrough in human history is born!!! ...
I wonder if anyone has guessed this result?
How to do this? I wonder if any big guys have predicted it in advance?
Xiao Zi will continue working first and come back to continue writing in the evening!
