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
