The Su God of the Reopening of the Sports Arena

Chapter 2216: Extreme Explosion! The code for the extreme speed explosion on the curve!!!

Xie Zhengye is here.

After the starting gun sounds, the brain quickly transmits signals to the relevant muscles, causing the muscles to contract rapidly.

At the same time, when starting with bent arms, the flexors and extensors of the arms coordinate with the muscles of the legs under neural control, so that the arm swing is synchronized with the leg extension movement, improving the coordination and efficiency of the overall movement.

When starting, the leg muscles contract rapidly, and the force is transferred to the ground through the rapid extension of the hip, knee and ankle joints.

After three points and one line.

Because the center of gravity moves forward and the feet press against the starting blocks in the preparatory position, a greater reaction force can be generated at this time, pushing the body forward and accelerating.

The arm bending movement is coordinated with the leg pushing off the ground, and the upper body is driven to rotate through the swing of the arms, which increases the stability of pushing off the ground and the effectiveness of force transfer.

Bang bang bang.

Cut into the curve.

At this moment, Xie Zhengye bent his elbows and swung his arms back and forth quickly and forcefully.

Bend your elbows appropriately when swinging forward, and fully extend your shoulders when swinging back.

The arm swinging movement can not only maintain the body's balance, but also drive the change of the body's rotational inertia through the swing of the arms, provide assistance for the legs to push off the ground, and at the same time speed up the forward movement of the body's center of gravity.

Help the body quickly get rid of the static state and enter the acceleration running stage.

After accelerating, Xie Zhengye gradually raised his body. This was to gradually adjust his body posture while maintaining forward momentum, in preparation for entering the mid-run.

As the speed increases, the body needs to be gradually upright to reduce air resistance and make the movement of the body's center of gravity more stable.

The arm swing plays a role in balancing the body and assisting in lifting the body during this process. The body posture and center of gravity are adjusted through the swing of the arms.

There is no problem at all.

The gradual adjustment of stride length and cadence is also very good.

On the one hand, gradually increase the stride length, and through further stretching of the leg muscles and active forward movement of the hip joints, gradually increase the span of each step.

If you know how to look at the forward extension number, you will find that he has already widened the gap with Zhou Bing.

On the other hand, this is also the key point.

His pace also gradually increased.

Much faster than Zhou Bing's side.

The contraction and relaxation speeds of the leg muscles are increased accordingly, which speeds up the frequency of leg alternation.

He runs with a typical flexed-arm start cadence pattern.

The swing of bent arms is coordinated with the adjustment of step length and frequency. The rapid swing of the arms drives the rhythm of the body and promotes changes in the frequency and amplitude of leg movements.

Keep the body in a coordinated state of movement during acceleration.

During the acceleration phase, the coordination between "pushing" and "swinging" is closer and more efficient.

With every step, one leg pushes the ground backwards while the other leg swings forward. The pushing leg fully extends its hip, knee and ankle joints, generating a strong reaction force that propels the body forward.

Ten meters, twenty meters, thirty meters.

At the same time, Xie Zhengye swung his legs quickly and forcefully forward and upward, actively driving the hip joint forward.

Provide greater supporting force for the backward kicking leg and increase the speed of pushing off the ground, and actively press down with the swinging leg to create conditions for "digging the ground in a curve".

The entire arm swing echoes the leg kicking action. The arm swing amplitude and speed match the leg movement, which together push the body forward and accelerate.

Doing better than before.

It's also much smoother than at the beginning of the season.

It can be seen that the team's condition is getting better and better after entering the middle of the season.

Break through Pb in front.

That's the obvious result.

Enter the bend.

Accelerate around the curve.

Xie Zhengye consciously leaned his body inward to overcome the centrifugal force of the curve.

The body's tilt angle is adjusted according to the curve radius and running speed. Generally speaking, the smaller the radius and the faster the speed, the greater the tilt angle.

At this time, the energy generated by the arm flexion plays an important role in maintaining the balance of the body's tilt.

Xie Zhengye's outer arm swings larger, while his inner arm swings smaller.

The large swing of the outer arm helps the body to generate a reaction force of centrifugal force outward, keeping the body balanced on the curve.

At the same time, it provides more centripetal force to the body, allowing you to run more smoothly on the curve.

When accelerating on a curve, Xie Zhengye needs to flexibly adjust his pace according to the curvature of the curve and his own speed.

And start to adjust the cadence appropriately.

In terms of details, due to the centripetal force of the curve, the stride of the outer leg will be relatively large, and the stride of the inner leg will be relatively small.

To adapt to the curved movement of the bend.

At the same time, the cadence will remain stable or increase appropriately depending on the need for acceleration.

The arm swing and step adjustment are coordinated with each other.

The swinging rhythm of the arms drives the rhythm of the legs.

Make the adjustment of your pace more coordinated and natural.

It helps you maintain a higher speed and accelerate on curves.

None of this is a problem.

Zhou Bing also did a good job.

When accelerating on a curve, the action of pushing off the ground is different from Xie Zhengye's.

But also absolutely superb.

In China, there are only Su Shen and Xie Zhengye.

There is no one better than him.

of course.

This condition applies to the whole of Asia.

That's about right.

I saw that when he kicked back, he used the inner side of the sole of his right leg to exert force.

Use the outside of the ball of your left foot to push.

To generate inward centripetal force.

Helps the body to better follow the curve.

And start to use the centripetal force of the curve to stretch your arm swing. Why? Of course, it is to increase the stride length and open up the stride length.

He is a stride type bent arm start.

The swing of the arms is naturally also special.

Except the outside arm swings a lot.

In addition to a smaller swing range for the inner arm, the direction of the arm swing will also change slightly.

The inward swing of the outside arm will increase appropriately.

The extent of the inside arm's outward swing will also be adjusted accordingly.

To better coordinate with the body's inclination and changes in pace, maintain body balance and provide forward momentum.

When he just started, his center of gravity was higher than Xie Zhengye, just like Zhao Haohuan was also higher than Su Shen when he started with his arms bent.

Then lift your hips slightly above your shoulders.

Make your body like a compressed spring.

Stores elastic potential energy.

Provide a good potential energy foundation for starting the race.

Precise control of the forward lean angle is one of the keys to Zhou Bing's current 200-meter starting technique.

It requires athletes to have good proprioception and balance. Zhou Bing has formed muscle memory through long-term training, allowing himself to maintain a larger forward lean angle every time he starts running.

In this way, when he bends his arms and starts running, the flexors and extensors of his arms and the muscles of his legs can better coordinate under neural control.

Synchronize the swing of your arms with the extension of your legs.

Improve the coordination and efficiency of overall movements.

Increase your starting stride.

This neuromuscular coordination is a complex process that requires athletes to continuously conduct special training to improve the nervous system's ability to control muscles, thereby achieving quick response and efficient movements at the start.

Zhou Bing has done such a good job here, which is enough to explain it.

He really trained hard.

No laziness.

Accelerating into the curve.

During the acceleration process, the movement of various parts of Zhou Bing's body follows strict biomechanical principles.

Taking the bent-arm start as an example, the flexion of his arms at the elbow can generate greater angular acceleration at the moment of starting.

According to the law of rotation, angular acceleration is proportional to the torque and inversely proportional to the moment of inertia.

When the elbow is bent, the arm's moment of inertia decreases, and under the same muscle strength, it can produce a greater angular acceleration, allowing the arm to swing faster and drive the body to start faster.

During the acceleration phase of a curve, the centripetal force generated by the body's inward leaning is the key to maintaining the curve.

This is also done very well.

According to the centripetal force formula F = mv/r, the faster the speed and the smaller the curve radius, the greater the centripetal force required.

By adjusting the body's inclination angle and the ground-pushing and arm-swinging movements, you can cleverly use the reaction force of the ground and your own muscle strength to provide sufficient centripetal force.

Ensure high-speed and stable running on curves.

Zhou Bing seemed to be telling everyone this.

For so many years.

I am in the Su Shen Department.

I am on Ersha Island.

I'm not a vegetarian either.

me too.

Read a book.

I read the newspaper. Good kid who studied Su Shen's paper!
pity.

They all did a great job.

But still.

And the Su Shen in front.

The difference is obvious.

It was mainly Su Shen’s shot.

It is really.

A bit too fast!

Especially when running on the middle of a bend, Su Shen's experience from both lives combined made him like a peerless master, opening up his Ren and Du meridians, and truly understanding what "corner talent" meant.

Him now.

This is the real Crescent Moon Scimitar.

The kind without the quotes.

Bang bang bang.

Accelerate around the curve.

Lower limb extensor muscles, stretch!
The front of the quadriceps and the back of the hamstrings form a "stretch-contraction cycle".

The hamstrings passively stretch to store elastic potential energy. At the moment of starting, the quadriceps contract rapidly concentrically. At the same time, the hamstrings cooperate to brake the excessive extension of the knee joint, forming an "elastic coupling" effect, which increases the power of pushing off the ground.

Bang bang bang.

Accelerate around the curve.

When the forefoot pushes off and lands, the tibialis anterior and peroneus longus form a "torque balance" at the ankle joint to prevent the foot from everting or varus and ensure that force is transmitted vertically along the tibia-femur-hip joint.

Bang bang bang.

Keep accelerating.

The forward swing of the deltoid muscle and the backward swing of the latissimus dorsi form antagonistic muscle coordination.

The biceps elbow flexion and triceps elbow extension are in the "isometric contraction preparation state".

Every time Su Shen takes a single step, his triceps contract quickly and concentrically to push his forearms backward.

At the same time, the serratus anterior pulls the scapula forward.

The arm swing amplitude increases by 15°-20° compared to the straight-arm start, which is called the change in the coronal plane angle of the shoulder joint.

coming.

Speed zone.

coming soon.

Su Shen did this mainly to give it a try.

Make the curve explode and be more powerful.

After all, the six-second burst on the straight road has stabilized the third stage, and even reached a new peak in the third stage.

We are going very fast on the curve, so we can’t fall behind, right?
Specific activation of unilateral muscle groups during cornering acceleration!
Fight against centrifugal force!
Lower limb joint division of labor!

The tibialis posterior and flexor digitorum longus of the inner leg are dominant.

Pushing the ground with the inner side of the arch generates an inward horizontal component of force, which offsets the lateral displacement of the centrifugal force.

Contraction of the anterior bundle of the gluteus medius internally rotates the hip joint, assisting the body in tilting inward.

The speed is further improved.

But not enough.

And more.

The peroneus brevis and peroneus longus of the outer leg exert force, and the outer side of the foot pushes against the ground to produce an outward reaction force.

Form a "torque pair" with the inside leg.

Keep your body moving along the tangent line of the curve.

It's faster.

but……

not enough.

Even faster!

Synergy of the trunk rotators!
The internal and external obliques form a "stabilizing spiral".

When running on a curve, the right internal oblique muscle and the left external oblique muscle contract synchronously, causing the trunk to rotate to the left about 8°-12° relative to the sagittal plane, reducing the shear force of the centrifugal force on the spine.

At the same time, it provides core support for the arm swing movement.

not enough.

almost.

But not enough!

Want more!

The power of Su Shen's push off the ground is transmitted through the rigid chain of "foot-calf-thigh-hip joint-torso".

The arm swinging posture keeps the scapula fixed, and the serratus anterior and rhomboid muscles contract, forming a rigid connection between the upper limb and the trunk, thus preventing energy from dissipating to the upper limb.

Then use the core spiral fascia chain to lock it and prevent it from collapsing.

If it is theoretically speaking.

At this time, the efficiency of transmitting the ground reaction force through the lower limbs to the torso can reach... 92%!

The spiral fascia chain's cornering and steering synergy!

You all have come up with new personal models for Corner Speed.

Could it be.

Su Shen.

Is that not the case?

just now.

It’s time to meet you all!
The three-dimensional integration mechanism of nerves, fascia and mechanics for extreme speed in corners!
Establish a new closed-loop control system of bent-arm start-fascia activation-center of gravity regulation!
Neural drive layer! Activate!
The bent-arm posture activates the tension receptors of the anterior superficial fascia chain through proprioceptors, transmitting "appropriate tension" signals to the central nervous system, thereby inhibiting postural compensation for excessively low center of gravity.

Fascial conduction layer! Activate!
The elastic recovery energy of the rear fascia chain and the torque transmission of the spiral chain cooperate with the angular momentum of the curved arm and the swing arm to form a multi-directional dynamic coupling, reducing the energy consumption of center of gravity control by more than 25%.

Mechanics output layer! Activated!
The angular momentum of the bent arm swing is superimposed on the elastic potential energy of the fascia chain.

Increases the horizontal impulse during the startup phase to 112% of the normal value.

The centripetal force reserve when cornering is increased by 30%.

After everything is done, use the low center of gravity in front to enter the curve.

Cooperate with the venue buff!

Su Shen seemed to have found something.

Bang!
The three-dimensional integration mechanism of nerves, fascia and mechanics for extreme speed in corners!
activation!!!
The direct effect of this is...

Six-second burst in the corner.

Phase 3!

liberation!

and.

Still that kind.

Touching the switch button is liberating!

A huge amount of energy seemed to be rising inside Su Shen's body!
It's like high explosives, exploding one after another inside the body!

Su Shen’s whole heart was roaring.

A joyful roar.

This feeling...

Flying!
fundamental.

I just can't help it!
Can't control it!!!
