The Su God of the Reopening of the Sports Arena

Chapter 2242 New Technology Support! Dual-Phase Drive

Except Su Shen.

Zhang Peimeng wants to enter the finals and is doing his best.

There's nothing I can do, this group is too complicated.

It's so uncomfortably rolled.

Zhang Peimeng has a clear judgment of his own strength, knowing that he will definitely not be able to enter the top four. If he wants to enter the finals, he must perform at a superb level.

Because their group only consists of Su Shen, Guy, Blake Carter.

There is a high probability that he cannot defeat any of them.

Then he must secure fifth place.

Only then can you win small q.

Although the 5th place in the previous group.

It’s Rogers with a time of 9 seconds.

Theoretically, as long as you exceed 9 seconds, you have a chance. But the problem is that the people in this group are not here to watch the show, and Zhang Peimeng understands that you only need to exceed 97 seconds.

People also understand.

What if this shot leads to a bloody fight?
That's the problem athletes of his level suffer from.

His hard power and on-the-spot performance may be better than the other three.

The problem is that if he tries too hard on this shot, then it won’t matter whether he makes it to the finals or not.

Because I no longer have the ability or condition to get another good result.

But what if this shot is not full strength?
That is also very difficult.

If you don't try your best.

There is a high possibility that they will be stopped halfway by people like them who are ready to sprint all out and reach the finals as the sign of success.

So this is Zhang Peimeng’s biggest worry right now.

But he is also a veteran who has experienced many battles.

I saw that Lao Yi, my direct competitor for many years, had already made it to the finals.

Zhang Peimeng was not willing to be outdone.

I thought I had to go in no matter what.

Standing on the playing field.

He set his goals very clearly.

Just get fifth place.

Get the fifth place with the best possible result.

Then enter the finals.

Zhang Peimeng had no choice but to take a gamble to complete the new skills he had learned during winter training.

It's called dual-phase drive technology.

In the traditional starting technique, athletes usually push off the ground with both their left and right limbs at the same time. Although this method of exerting force can generate greater force in an instant, it has obvious disadvantages.

According to the torque principle in mechanics, when the left and right limbs exert force at the same time, since the human body structure is not absolutely symmetrical, slight differences in the force points will cause unnecessary rotational torque to the torso.

This rotational torque not only consumes some of the energy that could have been used for forward propulsion, but also causes the athlete to deviate from the direction at the moment of starting, affecting the linearity and efficiency of the start.

The dual-phase drive technology builds a new mechanical balance system by allowing the left and right limbs to exert force to form a 180° phase difference.

Taking Zhang Peimeng's starting process as an example, when the left leg begins to push off the ground, the strong force acts on the starting block through the sole of the foot. According to Newton's third law, the starting block will give the human body an equal and opposite reaction force.

At this time, the right leg is in the preparation stage for swinging, and its muscles are in a relatively relaxed state, preparing for the subsequent force.

When the left leg's push-off action is nearing the end, the right leg quickly starts to push off the ground, and the left leg enters the swing phase.

This alternating method of applying force allows the ground reaction force to always act more concentratedly in the direction of the body's forward movement, converting more energy into forward momentum.

Research data from Su Shen's laboratory shows that by using dual-phase drive technology, the proportion of the athlete's horizontal component force in the total ground reaction force during the starting phase can be increased by about 8-12% compared to traditional technology.

Greatly improves the acceleration efficiency of the start.

However, the dual-phase drive technology places extremely high demands on the control ability of the human nervous system.

As the "commander" of human movement, the nervous system needs to accurately control the timing, intensity and sequence of contraction of the muscles of the left and right limbs in a very short time.

In the moment before the starting gun sounds, Zhang Peimeng's nervous system will enter a highly tense "standby" state. At this time, the cerebral cortex will send instructions to the spinal cord, and the spinal cord will then accurately transmit the nerve impulses to the various muscle groups of the lower limbs.

Specifically, 0.05 to 0.1 seconds before the gunshot, the quadriceps femoris, gluteus maximus and other muscle groups responsible for left leg extension are the first to receive nerve impulses and enter the isometric contraction pre-activation state.

This pre-activated state enables the muscles to reach maximum contraction intensity faster when they actually exert force, shortening reaction time.

When the gunshot sounded, the nerve signal activated the left leg muscles as fast as lightning, causing them to contract quickly and generate strong pushing force. At the same time, the nervous system immediately started the signal switching mechanism, and when the left leg pushed the ground to a certain extent, it quickly sent activation signals to the swinging and stretching muscles of the right leg.

Make sure that the right leg exerts force in time to form a continuous power output.

This process involves complex neural reflex arcs and neurotransmitter transmission in the nervous system.

For example, in the process of nerve impulse transmission, acetylcholine, as an important neurotransmitter, is responsible for transmitting signals at the neuromuscular junction to induce muscle contraction.

The dual-phase drive technology requires the nervous system to accurately control the amount and timing of acetylcholine release in order to achieve orderly activation of the muscles of the left and right limbs.

In addition, proprioceptive nerves also play a key role in this process, providing real-time feedback on muscle length, tension and other information.

Help the nervous system adjust the muscle contraction state according to actual conditions.

Ensure the accuracy and stability of force.

and so……

It's not easy to master.

Zhang Peimeng can master it.

It also took a lot of effort.

And the control is not very good at the moment.

I was thinking about polishing it for a while, but now it seems like it will be eliminated soon...

Zhang Pei took a deep breath and decided to use the technical points that he had not yet mastered.

See if you can help yourself break the current situation.

bang——

After the gunshot, Zhang Peimeng still tasted the familiar taste and the familiar recipe.

Start in third gear.

Bang bang bang.

Four points connected.

then.

During the start, the upper limb arm swing action is closely coordinated with the dual-phase drive technology of the lower limb.

Together they affect the starting effect.

According to the principles of sports biomechanics, the upper limb swinging movement can generate a torque opposite to the lower limb movement, which helps maintain the body's balance and coordination.

When the left leg pushes off the ground, the right arm will swing forward quickly and the left arm will swing backward.

The torque generated by this arm swinging method can effectively offset the body rotation tendency that may occur when the left leg pushes off the ground, allowing the body to maintain a stable forward leaning posture.

At the same time, the speed and strength of arm swing can also promote the force of lower limbs.

When the right arm swings forward quickly, the inertial force it generates will be transmitted to the lower limbs through the shoulders and torso, enhancing the ground-pushing power of the lower limbs to a certain extent.

When Zhang Peimeng starts running using dual-phase drive technology, he accurately adjusts the speed and amplitude of his arm swings according to the force rhythm of his left and right limbs.

For example, during the starting phase, at the moment the right leg pushes off the ground, the left arm will swing forward at a faster speed, synergizing with the force of the right leg to further enhance the explosive power of the start.

Even Su Shen Laboratory found that the combination of reasonable arm swing and dual-phase drive technology can increase the overall power output at the starting stage by about 5-8%.

Good start.

At least in the beginning I just couldn’t outrun those great players.

Acceleration zone.

The effective implementation of the dual-phase drive technique requires a strong and stable core muscle group.

The core muscles include many muscle groups in the abdomen, waist, buttocks and other parts. They are like the "central axis" of the body and play a key role in maintaining body posture and transmitting force during the starting process.

Especially the gluteus maximus.

This is also what Zhang Peimeng has been training for many years.

Now comes the key role.

In the process of alternating force between the left and right limbs, the center of gravity of the body will continue to shift. At this time, the core muscles need to respond quickly, adjust the body posture through contraction and relaxation, and maintain balance.

Bang bang bang bang bang.

Twenty meters.

Just as Zhang Peimeng kicked the ground with his left leg.

His body weight will shift to the left and forward.

The core muscles on the right side, such as the external oblique muscles and erector spinae, will immediately contract, generating a torque to the right to prevent the body from tilting excessively to the left.

At the same time, the core muscles are also responsible for transmitting the force generated by the lower limbs pushing off the ground upward to the trunk and upper limbs, so that the whole body forms a coordinated power chain.

If the core muscles are not strong enough or have poor stability, the body will easily shake and twist during the dual-phase drive process, resulting in reduced force transfer efficiency and affecting the starting speed.

The data provided by Su Shen Laboratory shows that for every 10% increase in core muscle strength, the power transfer efficiency when starting can be increased by about 6-9% using dual-phase drive technology.

Do these well.

The technological advantages will be reflected.

By alternating the force of the left and right limbs, energy loss and body rotation are effectively reduced, so that more energy can be used for forward acceleration. Compared with the original starting technique, a higher speed gain can be obtained after the start.

Sports wearable device data shows:

Athletes using dual-phase drive technology have an average speed of about 5 - 0.2m/s faster in the first 0.3 meters than those using the original technology.

Don’t underestimate it.

But the race is not five metres.

Accumulate.

It's not simple anymore.

Bang bang bang bang bang.

The next ten meters.

Zhang Peimeng immediately switched to a force mode with a 180° phase difference.

This allows the body to maintain better balance and straightness during the start.

The risk of wasting time due to direction deviation is reduced.

It helps you to establish a good race rhythm at the start.

And there is...

Reduce energy consumption.

In this startup acceleration technology posture.

The alternating force exerted by the left and right limbs allows Zhang Peimeng's muscles to have a short rest and adjustment time.

This avoids rapid muscle fatigue due to simultaneous high-intensity contraction, which is beneficial for the subsequent acceleration running stage.

The main reason why it was not used before was that the dual-phase drive technology requires extremely high nerve coordination and muscle control ability of the athletes, and it requires long-term special training and a lot of practice to master it.

Zhang Peimeng was not very confident about converting it into an effective display at first.

During the winter training period, Zhang Peimeng not only had to learn to accurately control the timing and intensity of the force of his left and right limbs, but also had to form a good coordination with movements such as upper limb arm swing and core muscle control. The training process was complex and challenging.

The most important thing is that this move...

The psychological requirements are extremely high.

Because the stability of this technology in the game is greatly affected by psychological factors.

If you feel nervous, anxious, or other emotions during a game, it may disrupt the rhythm of your left and right limbs.

This causes technical movements to be deformed and affects the starting effect.

Therefore, athletes who use dual-phase drive technology need to have stronger psychological qualities and the ability to withstand competition pressure.

After reading so much, you will understand why Zhang Peimeng has been reluctant to release it.

Indeed.

It's not easy to do.

And it's very psychological.

He is not Su Shen.

I don't have absolute confidence in this aspect.

But now, the competition is approaching.

There was no time to hesitate.

I can only make up my mind.

just start.

Bang bang bang bang bang.

When the left leg is extended, the right leg has completed the forward swing and entered the knee-bent folding state.

Use inertia to tilt the pelvis forward and shorten the support time.

Bang bang bang bang bang.

When the right leg extends, the left leg swings forward quickly, forming a continuous "whipping" force through the alternating rhythm of hip flexion and extension, reducing energy loss during the ground support period.

Although Zhang Peimeng's acceleration zone was no match for Su Shen and his group, he still had the fastest reaction in the game...

Pretty good.

Among all people, he is second only to Su Shen and Carter, and even faster than Blake.

of course.

Blake is in the back entirely because...

He didn't put in much effort in the preliminaries.

Otherwise he wouldn't be that bad now.

At least I won’t speed up and finish the run without going up.

Bang bang bang bang bang.

Run on the way.

Compared with the original technology, the dual-phase drive now adopted increases the cadence during the acceleration phase by 3-5%.

The efficiency of the support leg extension is improved by about 10%.

Because the direction of force is different from before...

More focused on the forward axis.

During the acceleration running and switching process, the forward leaning angle of the body gradually decreases.

Transition from about 45° at the start to 15-20° during the run.

The symmetry of the swingarm of the Dual-Phase Drive reduces air resistance.

Bang bang bang bang bang.

At this time, Zhang Peimeng's right arm swung forward, causing his shoulder to rotate.

Together with the extension of the left leg, it creates an anti-torsional moment in the trunk.

Keep your upper body stable and leaning forward.

Reduce the additional resistance caused by lateral sway.

At this time, Blake and Guy actually started to exert their strength.

His advantage was soon gone.

However, Zhang Peimeng remained unmoved.

Because he knows.

These two people are ahead.

That's a matter of time.

The core of this technology is...

Don't let your mind get in a mess.

The psychological quality must be strong enough.

Otherwise it will collapse all of a sudden.

That means it really collapsed.

He can be called the flower-grower version of Powell.

Hold still.

call.

Hold still.

call.

Hold still.

Zhang Peimeng began to try the speed energy inertia brought by the dual-phase drive and continued to move forward.

Speed ​​zone.

break out.

The men in front of him exploded.

And they are all higher than his explosive energy.

So……

You can use less energy to propel your body forward.

Alternating force pattern engages the antagonist muscles!

Quadriceps and hamstrings…take turns resting.

Reduce overall energy consumption!
Zhang Peimeng also began to certify more advanced technical systems.

He is worthy of being the man who can reach ten seconds using the traditional training method.

The man who almost took away the first place in the top ten of the yellow race of Su Shen.

This talent is really top.

The technical savvy is beyond reproach.

Especially the use of technology.

Some old system foundations come into play.

The problem has been explained.

Zhang Peimeng is really talented in this area.

In traditional techniques, exerting force on both legs at the same time will cause the antagonistic muscle groups to contract synchronously.

For example, when stretching, the abdominal muscles and back muscles are tense at the same time.

The dual-phase drive adopts the separation mode of single-leg support + single-leg swing.

Briefly relax the non-supporting leg muscles to reduce ATP consumption.

Increase your own… Phosphagen system load is reduced by about 15%.

In fact, the "intermittent high-intensity" mode of dual-phase drive can delay the occurrence of lactic acid peak and prolong the time of high-speed running.

But Zhang Peimeng is now...

Just do your best to help.

Bi-Phase Driven Neuromuscular Memory Strengthens Athletes' Innate Rhythm Perception!
He was surpassed when he was surpassed.

Never mind that!

Just be yourself!
Seventy meters.

Eighty meters.

Ninety meters.

Now it’s time for the later stages, which is Zhang Peimeng’s weakest part.

But one of the reasons he practiced this mechanism was to improve his later stages.

Just like what Su Shen did.

The ultimate prospect players can improve significantly.

With such a good goal and role model ahead, why would I give up?
There is no reason to give up.

Core transformation.

The core muscles shift from "posture maintenance" to "energy conduction hub".

During sprinting, the core muscles are regulated by intra-abdominal pressure.

The rhythm of holding your breath → exhaling.

Stabilize your torso.

The force of pushing off the ground by the lower limbs is transmitted to the arm swinging action through the lumbar spine-thoracic spine-scapula chain, forming a closed-loop power chain linking the upper and lower limbs.

This is when the advantages of new technologies begin to emerge.

It's not just about starting up and accelerating.

There are also dual-phase drive pre-training exercises that can enhance the endurance of deep stabilizer muscles such as the multifidus and transverse abdominis.

Reduce the "butt sitting" phenomenon caused by core relaxation while running.

That is, the body leans back and the angle of pushing off the ground becomes larger.

Although tired, I am still very tired.

But it is still tiring, but the speed can be increased.

because.

Lean back less.

because.

The local angle did not continue to expand rapidly as before.

With these, the speed will be sufficient later.

95 meters, 96 meters, 97 meters, 98 meters, 99...

Press the line.

Pressing the line is a must.

This is also the skill that Su Shen required him to master over the years.

He didn't understand it at the beginning, but now he has mastered it.

He would have done the same without Su Shen telling him.

finally……

Of course, Su Shen came first with 9 seconds, surpassing everyone else.

No one in this group can compare to him.

Blake finished second in this group.

The final score was 9 seconds.

Guy's result was third, and the final time was 9 seconds.

Carter finished fourth with a score of 9.88.

Zhang Peimeng finished fifth...

The time was 9 seconds.

Sixth place was Ashmid with a score of 9.95.

Seventh place was Collins with a score of 9.97.

Thompson is eighth.

As the third place in the 08 Olympics.

Now it's showing signs of aging.

His score didn't even open 10 seconds.

In the end, he only managed to achieve a time of 10 seconds on the small plateau in Lausanne.

The person who could compete with Su Shen for the title of Starting King in the Bird's Nest.

It has now completely lost its former charm.

This is the cruelty and charm of competitive sports.

In the end, Zhang Peimeng got the small Q as he wished.

Rogers was knocked out.

Qualified to the finals as ninth place.

Perhaps in the eyes of others, he spent so much money to squeeze into the finals but he is not competitive.

But for the parties themselves.

But it is an extremely rare opportunity.

Especially with Moscow just around the corner.

Zhang Peimeng.

You can feel it.

I've been in good shape recently.

Better than expected.

And it's much better.

A lot better.
