Su Shen burst out quickly.

This place is the key point.

It can even be said that the key points of this test are here.

What else would Su Shen say?

This game.

Should it be a breakthrough attempt in mechanical code?

It's not a joke.

Even if it's a joke.

There is something real hidden in his jokes.

Just like now.

Biomechanical mechanism.

During the 8-shaped arm swing process, the force generated by the swing of the arm is transmitted to the lower limbs through the shoulders, trunk and other parts.

It helps maintain the body's balance during high-speed movement and reduces energy loss.

The coordination and coordination of the swing arm and lower limb movements can enable the ground reaction force to be converted into forward propulsion force more effectively.

This is called the transmission and balance of force!

at the same time.

The 8-shaped swing arm also changes the body's moment of inertia.

Increases the stability of the body during high-speed movement.

A reasonable moment of inertia distribution helps athletes better control their body posture.

Reduce the extra energy consumption caused by body shaking, thereby extending the extreme speed zone.

This is called moment of inertia and stability!

When the arm swings in an 8-shaped shape, the distribution of airflow around the body can be optimized to a certain extent and reduce air resistance.

Especially when moving at high speed, air resistance has a great impact on sports performance. The 8-shaped swing arm saves energy for athletes by improving aerodynamic performance and helps maintain high-speed motion.

This is called aerodynamic effect!

Especially after entering the extreme speed zone, the 8-shaped arm swing technology requires the nervous system to accurately control muscle contraction and dilation.

Long-term training can improve the coordination of neuromuscles, enhance the recruitment ability and contraction efficiency of muscles, allow muscles to generate strength more effectively during the swing, and at the same time reduce the accumulation of muscle fatigue, so that athletes can maintain high-intensity exercise output for a longer period of time.

this……

It happens to be Su Shen’s strength, right?

In this life, he has been controlling and polishing muscles.

So to say so.

Even if he gets talent again, he can't say that he is the best.

But for muscle polishing and body control.

He can say it confidently.

In this world.

Inside the sprinter.

No one can surpass himself.

Whether you are Bolt or Terbo.

All the same.

No difference.

This is his body polished by his super self-discipline that has been ahead of the technology for decades.

here.

He has more confidence than anyone else.

Step by step, he knows more than anyone else what he has paid for.

Neuromuscular regulation, no one controls better than I do!

If the neuromuscle regulation is in place, the appropriate arm swing technique can optimize the energy metabolism process.

Now, the 8-shaped swing arm may adjust the body's movement rhythm to make aerobic metabolism and anaerobic metabolism work better together and improve energy supply efficiency.

Ensure the continuous and stable supply of energy during movement in the extreme speed zone.

Not to mention that arm swinging exercise is closely related to cardiopulmonary function.

The 8-shaped swing arm can promote blood circulation to a certain extent and increase ventilation in the lungs.

Improve the efficiency of cardiopulmonary function.

Provides more oxygen and energy substances for muscle exercise, and supports athletes to maintain exercise for a long time in the extreme speed zone.

This is the result of the interaction between biomechanics and physiology.

Why do we need technological progress in all aspects to be better in the current sprint? It is because after entering the 21st century, all walks of life in society have become cross-influence industries.

If you only work in one industry, it is impossible for you to improve essentially again.

The same goes for sprinting.

For example, the biomechanics of the extended speed zone of the 8-shaped swing arm technology include physiological coupling mechanisms.

If you don't go into a deep analysis of the biomechanical-physiological coupling mechanism behind it.

By integrating multidisciplinary research methods and revealing the unique principles of 8-shaped swing arm in optimizing sports performance, it cannot provide a scientific basis for athletes' training and technical improvement.

There is no scientific basis.

Now it's a mess.

No guidance.

Don’t look at how smoothly Su Shen is doing now.

Even he was the one who was the one who was there.

I also put in a lot of effort to conquer.

This is not enough for you to know theories and principles.

Need practice.

Only practice can produce useful things.

Otherwise, theories will always be just theory.

For example, motion trajectory analysis—

The three-dimensional motion trajectory of the 8-shaped swing arm is accurately recorded using a high-speed camera and a motion capture system. The results show that the arm forms a continuous 8-shaped swing in the sagittal and coronal planes, which is significantly different from the traditional and circular front and rear swing arm methods.

Measure kinematic parameters such as frequency, amplitude and speed of the swing arm. Data are used to show that the frequency of the 8-shaped swing arm is slightly lower than that of the traditional swing arm, but the swing amplitude is larger and can generate greater angular momentum.

Through dynamic analysis, the magnitude and direction changes of the force generated by the 8-shaped swing arm at different stages were revealed.

The swing of the arm not only generates propulsion force in the horizontal direction, but also adjusts the ups and downs of the body's center of gravity through vertical direction components.

With the help of musculoskeletal model, we study the path of force transfer from the arms through the shoulders and trunk to the lower limbs. We found that the 8-shaped swing arm can more effectively transmit the upper limbs' strength to the lower limbs and enhance the pushing and stretching force of the lower limbs.

Can you handle these things behind closed doors?

There is no cross-research help for the rest of the disciplines.

You can't figure out why even if you have ten thousand years.

Bang bang bang bang bang bang bang.

After a rapid explosion.

Based on experimental data, the influence of the 8-shaped swing arm on the body's moment of inertia was analyzed.

The results show that by changing the way the arm swings, the body's moment of inertia is optimized during the movement, which helps maintain body balance and stability.

This is both a change in moment of inertia.

Another change in the balance control mechanism.

Discuss how 8-shaped swing arm can help athletes maintain physical balance during high-speed exercise.

Laboratory research has found that the reaction torque generated by the swing arm can offset the unbalanced torque generated by the body due to changes in speed.

If you don't know these principles.

I will never be able to touch the core veins in my life.

Then, using surface electromyography technology, the activation mode of the main muscle groups of the upper and lower limbs during the 8-shaped arm swing process is recorded. See the results to

The 8-shaped swing arm can activate muscle groups more evenly and improve the efficiency of muscles' collaborative work.

The nervous system's control strategy for the 8-shaped swing arm was studied. It was found that the brain achieved precise control of complex swing arm movements by adjusting the frequency and order of nerve impulses.

Indirect heat measurement method is used to measure the energy consumption during the movement of the 8-shaped swing arm.

The results show that at the same speed, the energy consumption of the 8-shaped swing arm is slightly lower than that of the traditional swing arm, indicating that it has higher energy utilization efficiency.

Monitor the changes in cardiopulmonary function indicators such as 8-shaped swing arm movement center rate, oxygen uptake and lung ventilation.

The 8-shaped swing arm was found to enable the heart and lung system to work more efficiently, providing the muscle with sufficient oxygen and energy substrate.

Just ask.

Does anyone know these?

Do other sports teams have this understanding?

In order to study this, Sushen Laboratory constructed a biomechanical-physiological coupling model of 8-shaped swing arm technology based on experimental data.

The model integrates multiple factors such as force transmission, muscle activation, energy metabolism and nerve control, and can fully describe the working principle of the 8-shaped arm swing technology.

Research has discovered the role of proprioceptors in the 8-shaped swing arm.

It was found that proprioceptive feedback can monitor the body's movement status in real time and feed back information to the nervous system to adjust arm swing movements and muscle activation patterns.

Then Su Shen is now.

You can consciously mobilize these aspects.

Make your own speed stronger, faster and more fierce!

At this time, the effect of a powerful laboratory is shown-

Comprehensive use of motion capture system.

Dynamic measurement platform.

High-end surface electromyography.

Advanced measurement technologies such as sprint indirect heat measuring instruments.

Wait and wait.

To obtain multi-dimensional experimental data.

There are no such devices.

So what if you know the principle?

How to switch to sprint?

How to convert it to athletes?

Still don't know anything.

With these data, discussing the angle of energy transmission and transformation has practical significance.

Just like Su Shen who is in the Speed ​​Zone now.

Using an 8-shaped swing arm can make the energy of upper limb movement more efficiently transmitted to the whole body.

When the arms swing, energy is transmitted to the lower limbs in a specific way through the synergy between the shoulders and the trunk.

This allows lower limbs to gain greater strength support when pushing the ground.

This increases the body's forward propulsion, which in turn helps maintain higher speeds.

During this energy transfer process, the contraction and dilation of muscles in various parts of the body are more coordinated, and the energy conversion efficiency between muscles is improved.

The 8-shaped swing arm allows muscles to better utilize the phosphogenic system, glycolysis system and aerobic oxidation system when working, providing the body with appropriate energy at different stages of exercise, reducing the loss of energy during the conversion process, and ensuring the continuous supply of energy during the extreme speed zone.

An 8-shaped swing arm requires the coordinated participation of muscles in multiple parts such as upper limbs, shoulders, back and core.

This arm swing method can enhance the ability of coordinated contraction between muscles, enable the body to maintain better posture stability and movement coherence during exercise, reduce the loss of strength and movement deformation caused by muscle inconsistency, and provide a stable power basis for maintaining extreme speed.

This is the biomechanical aspect.

The nervous system's precise control of the 8-shaped swing arm requires continuous feedback and adjustments based on the movement state.

In this process, the excitability and flexibility of the nervous system are improved, and the muscles can be issued more quickly, optimizing the muscles' reaction speed and contraction force.

At the same time, the nervous system can reasonably allocate muscle workload according to the body's fatigue degree and exercise needs to avoid premature fatigue of local muscles, thereby extending the body's exercise time in the extreme speed zone.

This is a physiological aspect.

Compared with traditional swing arms, the 8-shaped swing arms can change the distribution of air flow around the body during movement and reduce the impact of air resistance on the body.

When the arm moves in the 8-character trajectory, two small air flow guides are formed on both sides of the body, guiding the air flow through both sides of the body more smoothly, reducing the pressure on the front of the body, reducing the air resistance the body faces when moving forward, which is conducive to increasing and maintaining speed.

Due to the reduction of air resistance, the body does not need to consume too much energy when exercising to overcome air obstacles. This allows the cardiopulmonary system and muscle system to use more energy to generate propulsion and maintain the body's movement state, so that under the same energy reserve, it can maintain movement in the extreme speed zone for longer.

This is an aerodynamic angle.

You don’t know these, what are you going to study?

To teach athletes to make progress?

Sixty meters.

...

Su Shen had already felt that he had started to enter the maintenance zone at a rapid speed.

I saw his arms swinging continuously in 8 shapes on both sides of his body, and the front and back swing trajectories were connected to each other, forming a smooth cyclical movement.

During the swing, the arm stretching and bending are coordinated, and the shoulders are fully involved in driving arm movement.

Seventy meters.

When the arm swings, muscles contract and generate motivation.

Due to the complex trajectory of the 8-shaped swing arm, the direction and size of the muscles at different stages have rich changes, which can generate multi-dimensional force components and provide more comprehensive power support for the body.

Eighty meters.

The force generated by the swing arm is transmitted to the lower limbs through the shoulders and torso, which is coordinated with the force pushing the ground with the lower limbs. In the 8-shaped swing arm, the transmission of force is more coherent and directional, making the ground reaction force more efficiently converted into forward force and improving propulsion efficiency.

This is the previous question.

Enter the final sprint.

The better your physical fitness, the faster your

The higher your speed, the faster it will be

But there is another type that Su Shen does now-

The lower your lactic acid accumulation rate.

nature.

The faster it will be!

Ninety meters!

The 8-shaped swing arm changes the movement radius and mass distribution of the arm, thereby adjusting the body's rotational moment of inertia.

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! During the exercise, reasonable changes in moment of inertia can help maintain body stability and reduce energy loss caused by shaking.

Ninety-five meters!

When the body is affected by external interference or changes in its own movement during high-speed movement, the 8-shaped swing arm can adjust the swing amplitude and speed.

Generate corresponding reverse torque.

offset imbalance.

Maintain body balance.

Ensure stability and sustainability of movement.

Especially the more tired you are, the more unstable your body will be.

The more lactic acid rate is accumulated.

Su Shen found a new solution.

Use science.

Reduce your own accumulation rate.

Give yourself physical fitness.

Continuously strengthen and improve through science.

This path.

At least this timeline now.

Only Su Shen is doing it.

He is the only one who tried it.

The rest?

The rest of the team?

The rest of the coaches?

Sorry, it's not that they don't want to.

Such a complex mechanism, cross-fusion, tests their brains too much.

So, I didn't even think about this aspect.

Don't mention the actual conversion.

Only Su Shen.

Use science to cheat.

Use the knowledge system to make cheats.

Clear theories one by one.

Detailed data one by one.

Solid papers one by one.

A trace has come out.

It’s not just a path that can be taken by talent.

The rise of a genius can bring honor, but when this genius comes to an end, it has little impact on the improvement of the entire industry.

Because there is no way to make a detailed analysis of talent.

It is only a specialization of the individual.

But Su Shen like this.

Totally different.

He has paper support for every step.

Every time he makes progress, he will have new scientific theories as the basis.

Every time he improves, you can find out what changes he has made.

These things are sorted out then.

This is what really affects the entire track and field pattern of the flower family.

It's the real track and field world.

Priceless treasure.
