The hips are delivered stably in conjunction with the hips, and the amplitude of each step is about 10 degrees to 15 degrees.

This force was like a surging undercurrent, rushing towards the hips.

The hip muscles respond quickly under the guidance of the curved arms, and use the hip joint as the axis to start the exquisite hip-sending action.

Is the bending arm burst used to improve the lack of force in a woman's hip delivery?

It's a good idea.

Su Shen looked at it.

Nodded silently.

Seeing Chen Juan's initial hip delivery, it was like a mechanical gear accurately biting. The hips were slightly erected and raised upwards. Although the amplitude was small, it was extremely critical. It fitted closely with the rhythm of the swing of the bent arms, making the body's center of gravity jump forward and upwards smoothly.

The leg muscles are linked by this, and the force of the rear kick is like a rocket boost, strong and efficient.

The torsional moment generated by the bending arm burst acts accurately on the hip joint complex through the conduction and integration of the core muscles of the body.

For example, now, when the curved arm bursts and pushes the body, at about 45 degrees behind, the hips start to move hips along the direction of the center of gravity shifting in the front and upper direction under the power transmission of the core muscle group.

At this moment, the swing acceleration of the bent arm gradually increases, forming a dynamic enhancement effect on the hip-sending action.

When the bent arms start, the arms bend to form a shorter force arm. According to the principle that the moment is equal to the force multiplied by the force arm, when the muscle strength is certain, the shorter force arm can make the shoulder and upper limb related muscles, such as the deltoid muscle, biceps and triceps brachii, more efficiently generate larger moments, thereby providing a considerable initial rotational power for the start.

This rotational power can be transmitted and integrated through structures such as the core muscle groups and fascial chains of the body.

Among female athletes, due to the physiological structure and muscle strength distribution characteristics, it is difficult to generate sufficiently strong initial propulsion force alone at the start of the hip.

The rotational power generated by the starting of the bent arm can be transmitted to the pelvis and hip areas, which can greatly solve the problems of this century.

It can provide additional power supplements for hip-sending actions, allowing them to overcome greater static inertia at the beginning of the start.

What a smart combination.

Su Shen looked at him and became more and more appreciative.

You have to know these, but Chen Juan’s own team and herself explored the direction. She just showed Su Shen when she made the final decision, hoping that he would determine whether the direction was correct.

The rest were done by Chen Juan and her team themselves.

You can think of using technological breakthroughs to drive the improvement and development of other technologies, especially to supplement your own shortcomings.

This shows that Chen Juan’s team and his own thoughts are gradually maturing.

This idea is absolutely fine.

There is a relationship between Su Shen setting the direction.

Chen Juan’s entire team doesn’t have to think too much about doing it, and doesn’t have to think that the whole direction is wrong and start over.

Just devote yourself to it.

They found that from the analysis of the principle of muscle movement, the contraction timing and synergistic method of upper limb muscles when the bent arm starts help the concentrated burst and transmission of energy.

After asking Sushen Laboratory, I confirmed a little bit—

The upper limb muscles quickly contract in a specific order, for example, the deltoid muscles first start to stabilize the shoulder joints, and then the biceps and triceps brachii contract together to generate the force of the bent arm swing.

This ordered contraction mode can quickly convert muscle elastic potential energy into kinetic energy and transmit it to the lower limbs and hips through the body's dynamic chain.

For female athletes, the activation degree and power output rate of their hip-related muscles such as the gluteus maximus, gluteus medius, etc. at the start are relatively slow.

The additional power input from the upper limbs provided by the curved arm start can fill the shortage of initial power supply of hips, allowing the overall body to run in a closer-to-ideal power output mode during the starting stage, thereby optimizing the starting effect.

Significantly increase the starting speed and lay a good foundation in the subsequent acceleration process.

Not to mention that starting a bent arm can activate more neuromuscular units to participate in the starting movement. Compared to relying solely on the activation of lower limbs and hip muscles, the bent arm involves complex upper limb neuromuscular control networks.

At the moment of starting, the exercise instructions issued by the brain activate the related muscle groups of the upper and lower limbs at the same time, causing more muscle fibers to be recruited.

For female athletes, the hip-sending neuromuscular control may be relatively inaccurate and efficient at starting, and the widespread neuromuscular activation brought about by bent arm start can make up for this deficiency.

That is to say, by increasing the excitement and coordination of the overall neuromuscle, the hip-sending movements are better started and performed, and the propulsion force is enhanced at the start.

therefore……

Chen Juan is actually trying to beat Fraser here!

Nothing at all.

This is not the Fraser who was not in a very online state before. After all, even Fraser still ran for more than 11 seconds.

Actually, today's situation...

She is very good.

In Su Shen's impression, it should be 0 wind speed.

It ran to 10 seconds 93.

Do you think it's strong?

This is the first appearance of the season.

Fraser 10 meters in front, but many athletes who were in the back-range stage could not withstand it.

How terrible you say.

I didn't expect to be here.

It was actually caused by Chen Juan who was so tall.

Frontal hard work.

Even Fraser has not reached the best of the season yet, which is really terrible.

This height.

No matter how many times it comes.

All shocked Fraser.

It made her want to have a glimpse into the beginning of the bent arm.

Compared to these two people.

Ocabare.

It's not on the same level at all.

Even worse than Wei Yongli, who was the first one.

Ocabarre's start-up is the woman's start-up speed for a real big athlete.

In fact, Chen Juan had some similarities before.

But now.

She has gradually begun to overcome it.

Start here.

It is impossible for Ocabarre to catch up with her again.

Of course, the future is not a joke, but only the future is only 100 meters.

Don't believe it.

If you don’t believe me, look at Su Shen.

What is surprising is.

Jetel is in an average state.

Starting very slowly.

There were still 10.70 last year, and this year it was not as good as before.

This year is even her last peak tail.

However, many people will choose to let go of a year after the Olympics. When everyone confirms that the streets have completely declined, they will not count from next year or even the year after the competition year.

In fact, she ran a 10 seconds 95 in the last game.

The Cayman Invitational race in Georgetown was a great one.

But I have said before, what is the initial performance of a super athlete starting to aging? It is not a sudden decline, nor is it lacks highlight performance.

But...

Begins to be unstable.

Remember this and you will discover the true meaning of all athletes going downhill.

This is the beginning of Jetel's instability.

She can no longer maintain good form at the beginning of the season, nor can she continue to produce good results.

I only had a good result in the last game, but I immediately couldn't recover from this game.

The state is exhausted.

In the first three duels, she was the first person to fall behind.

The entire game became a two-player showdown between Chen Juan and Frazer.

Acceleration zone.

Fraser's thigh tensile fascia lata muscles coordinate with the quadriceps and other muscles to maintain the stability of the leg movements, and the calf muscles work quickly and alternately.
