Going to the late stage.

Going to the high point of your career.

The more you can feel it.

How strong are these so-called basic tasks that Su Shen helped her do?

Here on Ersha Island.

No core is bad.

Especially small teams.

The worst Zhou Bing.

His core abilities are actually better than the other first-team players in the previous quarter.

Only the main core is stable can continue the following work.

It reached the last 20 meters.

Chen Juan also needs to show her real skills.

It should be known that the twisting movement of the shoulder is mainly completed by multiple groups of muscles.

The deltoid muscle is one of the main muscles of the shoulder. It is divided into three bundles, one middle and one back. The contraction of different bundles can cause the shoulder to move in different directions.

During the shoulder twisting process, the anterior and posterior deltoid muscle bundles cooperate with each other to achieve the twisting movement of the shoulder.

At this time, the pectoralis major and latsimum dorsi are also involved. When the pectoralis major contracts, the shoulders can be adducted and rotated, while the latissimum dorsi can be contracted and rotated. When the pectoralis major contracts, the latissimum dorsi helps shoulder abduction and rotation.

In addition, small muscle groups on the shoulder, such as the supraspinatus, infraspinatus, teresmis and subscapularis, play an important role in maintaining shoulder stability and precisely controlling shoulder movement.

These small muscle groups can fine-tune the position and angle of the shoulders to ensure that the shoulder joints remain stable during shoulder twisting.

This is the first step.

It is called shoulder muscle coordination in the sprint area.

Then there is the second step.

The shoulder joint is one of the most flexible joints in the human body. It consists of the scapula, clavicle and humerus, connected together by a variety of ligaments and muscles.

This complex structure allows the shoulder to perform a wide range of movements, including forward flexion, posterior extension, abduction, adduction, internal rotation and external rotation.

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! In the process of the shoulder producing stable torsional force, the structure of the shoulder joint plays an important supporting role.

The ball and socket structure of the shoulder joint allows the humerus to rotate freely within the glenoid, providing a broad range of motion for the twisting of the shoulder.

At the same time, the ligaments and muscles around the joints can limit excessive movement of the shoulders and ensure the stability of the shoulders during torsion.

Just like the glenohumeral ligament can prevent excessive anterior and posterior dislocation of the humerus.

The corosaurus ligament can limit excessive abduction of the shoulder.

These ligaments and muscles work together to ensure that the shoulder maintains normal motion trajectory and stability when generating torsional forces.

Those.

What can it bring?

Can bring...

Action coordination and frequency acceleration!

Bang bang bang bang bang bang bang.

Eighty-five meters!

During the 100-meter rear and sprint stages, the athlete's physical fatigue gradually increases, and it becomes more difficult to maintain high stride frequency.

The stable torsional force generated by the shoulder can help athletes maintain the correct running rhythm and improve pace by coordinating with lower limb movements.

I saw that when Chen Juan used her shoulders to steadily twist, it would drive her body to rotate at the same time.

This rotation forms a synergistic effect with the pushing and swinging movements of the lower limbs.

Chen Juan knew that there were countless experts in this game.

She can only use her as much as possible to have some hope.

Hope what is of course...

To win the championship.

Even the opponent is Fraser.

Even if the opponent is Brown or Ocabarre, there are others.

All……

It doesn't matter.

At least this shows Chen Juan’s current mentality.

There has been a huge change.

Even under the pressure of this lineup.

She thought first now.

Yes, how, win.

Is there a chance to win?

This is the cognitive change that gradually accumulates through the honors of the competition.

If it was placed in the track and field environment in China in the past, I'm afraid she wouldn't dare to think about it if you tell Chen Juan what she thought.

If she hadn't won so many honors in these 10 years, she would have made continuous breakthroughs in the international arena.

Then she probably won't, or she doesn't dare to think so.

Bang bang bang bang bang bang bang.

When one side of the shoulder twists forward.

The hip joint on the same side of Chen Juan will also rotate forward accordingly, driving the lower limbs to swing forward faster, thereby increasing the pace frequency.

This coordination effect allows athletes to maintain a high pace frequency when they are tired!

Provides strong power support for sprints.

Afterwards.

That is, the twisting movement of the shoulder not only involves physical movements of muscles and joints, but also produces feedback and regulation through the nervous system, further affecting the pace frequency.

When the shoulder twists, the muscles and joint receptors of the shoulder will send signals to the brain. After the brain receives these signals, it will adjust the nerve control of the lower limb muscles according to the body's movement state and target speed.

It is necessary to use this feedback regulation mechanism to enable lower limb muscles to contract and relax more quickly and accurately, thereby increasing the pace frequency.

It's like entering the sprint stage.

When Chen Juan increased the twisting range of her shoulders.

The nervous system will receive stronger signals, prompting the lower limb muscles to contract faster and achieve the improvement of pace frequency.

this.

If you don't understand kinematics and neurology, and the connection between these two people.

It is impossible for you to understand this point.

I can't understand it anymore, so it is naturally impossible to train and improve targetedly.

Bang bang bang bang bang bang bang.

Ninety meters.

At this time, Okabarre also felt something was wrong, Chen Juan, how to go ahead...

So powerful?

It’s not that I look down on Chen Juan.

It's just in the past cognition.

Although Chen Juan's future is amazing.

But then we have to see who we compare with.

Compare with yourself...

It's undoubtedly a little bit short.

Then, Chen Juan hasn't stopped yet.

Does she mean to stop?!

No.

She has to rely on the stable torsion force of her shoulders to increase the rotation range of her body.

Provides more space for leg extension.
