...

You will understand this result as soon as you come out.

The overall sprint level this year has declined compared with last year's Olympic year.

And the decline is not a little bit.

Xie Zhengye, an emotional person before the game, would blow everyone up.

Where can I know?

It was really fulfilled.

And he also achieved the best results in his personal career.

You can't even run out of the 0.9-meter wind speed.

There is nothing we can do about it.

These people looked at Xie Zhengye who was dissatisfied with them.

I was a little embarrassed and speechless for a moment.

Don't know what to say.

Or shouldn't say it.

The momentum in the waiting area.

It was already in front of Xie Zhengye's achievements.

He was beaten into pieces.

The rooster can't even lift its head.

It was the turn of the final 100-meter battle.

First of all, the woman is a hundred meters.

Chen Juan and Wei Yongli played together.

It was just a Taoist priest in the middle, and the other was on the ninth road here.

This is nothing to do.

After winning the Olympic medal, Chen Juan earned herself a strong position in the circle.

As a new Olympic medalist, he was the top three strongman last year.

It's okay to arrange it in the central position.

Wei Yongli had no choice but to be by the side.

However, she had known this problem for a long time, and everything had to be fought for by her own strength.

She has basically made no achievements internationally now.

The arrangements there are very reasonable here.

Anyway, our Asian-level achievements are not enough on the international stage.

It's useless to take it seriously.

You need others to take you seriously.

Otherwise, no matter how good or more you get in Asia, you won’t have much competition on the international stage.

This question.

Chen Juan said it very early, Wei Yongli said it.

Because this is all Chen Juan's own empathy back then.

Although Chen Juan has come to this position now, she has not lost any of these experiences at the beginning.

Taste all.

The first step is Schilloni Calvert Powell.

The second leg was Jessica Young Warren.

The third Jamaican Brown.

The fourth story is Chen Juan.

The fifth road Arlene Bailey.

The sixth way Mikel Barber.

The seventh way Lake Isa Lawson.

The eighth Dotiana Bartoletta.

The ninth Way Wei Yongli.

Similar to the situation at 200 meters.

They are all the same, either American or Jamaican.

This has been like this for so many years.

Only.

I don't know when it starts.

In these melee between Jamaica and the United States, some yellow figures gradually added.

At first, everyone was definitely not used to it.

But it's been several years.

In addition, Chen Juan won the bronze medal in 100 meters in London last year.

Even Amika's audience now.

The so-called noble American viewer.

They are also slowly adapting to this.

Whether it is active or passive.

All have to adapt.

"Okay, we can see that Team USA has not sent out their strongest seed players."

"It seems that after the Olympic Year, everyone is resting fully."

"This is also a very normal situation, especially track and field sports, which will cause a lot of damage to the body. It is usually very normal to choose to relax the body after the Olympic year and give time to recover."

"Of course, the United States is still very strong."

"It can be seen that many people can still be drawn to participate in the competition."

"If nothing unexpected happens, the champion should be decided between Chen Juan and Brown."

"Chen Juan always has a tradition of winning the game against Brown."

"I wonder if this time it can be copied."

Brown himself is not willing to listen to what Yang Jian said.

Because such video jokes and dynamic screenshots on the Internet can be said to be common.

After the arrival of the mobile Internet era.

The number of people using the network can be said to have increased geometrically compared to before.

That's about all kinds of second-creation productions.

It will also soar straight.

The scene of Brown being killed by Chen Juan's chest.

It's really classic and funny.

And that's for Brown himself.

No less than secondary damage.

It was depressing enough to lose the game and be killed.

As a result, I will see it on the Internet when I look back.

People joked that they lost because their breasts were not big enough.

Tell me.

This damn track and field rules.

Why just look at the torso?

Then my breasts can only develop so big, I blame myself.

Do you think Brown doesn't want to grow bigger?

Don't have this ability, do you know?

And girls compare this.

It's somewhat disgraceful.

The key is to lose to an Oriental.

I don’t know if Brown won the championship in 200 meters or if there are other reasons...

It's really the same as the original historical line.

It was announced that the game was abandoned before the game.

This made Chen Juan, who was warming up, confused.

Not sisters.

Why didn't you run away?

I just saw that you have no problem yet?

Chen Juan saw Brown raise his hand to withdraw from the competition, walked over and wanted to care, and asked Brown if he had suffered a pain in his chest?

But at this time.

"Breast", the word.

It's like a sensitive forbidden word.

I felt a little shocked when I heard about Brown.

He left with a dark face.

He didn't even lose a word.

Of course she was already dark enough.

Chen Juan:???

What's the situation?

Why does it seem like I have offended her if I care about it?

well.

These European and American sisters.

It's really difficult to deal with.

Brown quit the game, that's just a small episode, and the game won't stop because of someone.

After the referee announced that Brown had withdrawn from the game.

The rest were ready on the runway.

A battle between 8 people.

Get ready to start again.

set.

Bang----------

Jamaica's Schilloni Calvert Powell's instantaneous explosion was amazing, with a rear pedal angle of about 45 degrees, which could efficiently convert strength into an initial speed forward. He pushed his hands off the ground with his hands and lowered his head and leaned forward angle moderately.

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! Her teammate Arlene Bailey took a safe and sound approach of moderate force when starting. After pushing his hands off the ground, his body leans forward angle and enters the acceleration stage smoothly.

American player Mikel Barber responded with a quick response when starting, with only 0.135 seconds. Then he pushed his feet straight and his hands off the ground quickly, and his body leaned forward in time.

Get a faster initial speed from the beginning.

She wanted to build enough advantages from the beginning.

Give yourself a buffer space.

pity……

There is a Chen Juan here.

Chen Juan, who has mastered the bent arm start.

Unless it's Fraser here.

otherwise.

None of these people are enemies of one unity.

This year's winter training, there was enough time. She started to snag her arms and started to snatch it again.

She really found a lot of feelings...

The structural characteristics of the body, including women, determine that their center of gravity is relatively low and closer to the central axis of the body.

Focusing on the point, the entire team began to upgrade their technology.

From an anatomical perspective, compared with men, the pelvis is relatively wide, and the skeletal structure of the lower limbs also has differences in morphology and proportion, which makes the center of gravity of the female body relatively lower and closer to the central axis of the body when the female is naturally standing.

This center of gravity distribution is determined by the physiological structure of women. During exercise, especially in the starting stage of short running, it will have an important impact on the stability of the body and the transmission of strength.

This shows that compared with men, women's characteristics need to be modified.

Then, based on this basis, according to the principle of center of gravity stability in mechanics, the lower the center of gravity, the higher the stability of the object.

Then at the start moment, the lower center of gravity of a woman can provide a greater stable torque.

This makes it less likely that the body will be instable such as excessive forward leaning or rolling when it is subjected to strong rear pedal force and forward impulse at the start.

This can lay a solid foundation for this to follow-up acceleration process and reduce energy loss and velocity losses caused by unstable center of gravity.

Based on these scientific points, you can get the fine adjustment and changes of technology.

Compared with the previous bent arm start, Chen Juan has made adjustments before starting, such as before the bent arm starts, her arms bent and her elbows are closer to both sides of her body than last season!

This posture reduces the swing radius of the arm, so that it can swing faster at the start, and the direction and force of the swing are easier to control.

It is not easy to do it, first of all, high-speed camera analysis is required.

This is also the primary habit of modern track and field.

Like the previous empiricism, it will only become more and more backward.

In other words, during Chen Juan's training and competition, he used a high-speed camera to shoot the starting process from multiple angles, including front, side, and top-down.

The frame rate is set to 1000fps to accurately capture the details of the starting posture and the dynamic process of arm swing.

In conjunction with electromyography signal monitoring - that is, using a surface electromyography instrument, attach electrodes to Chen Juan's anterior, middle, posterior, chest and arms, such as biceps, triceps and other related muscle parts, collecting electromyography signals during the start process, and the sampling frequency is 2000Hz to analyze the activation degree and force characteristics of the muscles.

Then, a force plate launched by Sushen Laboratory was installed below the starting device to measure the force, direction and action time of Chen Juan's feet when she started. The sampling frequency of the force plate was 1000Hz, thereby evaluating the force effect of the lower limbs at the start and its synergy with the upper limb movements.

According to high-speed camera data analysis, this is because the elbows are closer to both sides of the body, which significantly reduces the moment of inertia of the arm.

Then through calculations, we can know... the moment of inertia of the arm is reduced by about 25% compared to last season!

Based on the simplified human arm model calculation, assuming that the arm is a uniform thin rod and the rotational moment of inertia formula, the reduction of the rotational moment of inertia allows the arm to obtain a larger angular acceleration and thus achieve a faster swing speed.

In conjunction with electromyography signal analysis, the average electromyography amplitude of the deltoid anterior bundle of Chen Juan when she started to adjust this way reached 4.8mV, an increase of 14.29% compared with 4.2mV last season; the average electromyography amplitude of the pectoralis major muscle increased from 3.5mV to 4.1mV, an increase of 17.14%.

This shows that the adjustment of the elbow allows the relevant muscles to be activated and synergistically effective at starting.

Due to the reduced swing radius of the arm, the stroke of muscle contraction is relatively shortened. The muscles can achieve the maximum contraction force faster within the same time, thereby improving the muscle's force efficiency.

At the same time, the direction of muscle force exertion and the direction of arm swing are better consistent, reducing the decomposition and loss of strength, allowing more muscle strength to be directly used to push the body forward.

The force plate test data shows that Chen Juan's average level component force when she kicked the ground with her feet increased by 8.33%; the average acceleration in the first 10 meters after the start increased by 8.57%.

This proves that the increase in arm swing speed and strength forms a more effective synergy with the lower limb pushing action.

The rapid and powerful swing of the upper limbs can generate a forward and upward pulling force, which cooperates with the forward and downward thrust generated by the lower limbs pushing the ground through the body's musculoskeletal conduction system.

This makes the direction of the combined force the body is subjected to when starting is closer to the horizontal, thereby further improving the acceleration performance of the starting.

Then after rigorously analyzing the data, you can draw a conclusion-

Through scientific analysis of Chen Juan's starting posture adjustment, it can be seen that the change of the arms bent before starting and the elbows are closer to both sides of the body has brought significant improvements in the swing speed of the arm, muscle activation and force, and starting acceleration performance.

The structural characteristics of a woman's body determine the argument that her center of gravity is relatively low and closer to the central axis of the body.

This chapter is not over, please click on the next page to continue reading! That's what you see now.

When activated, the arm bends and the rotation radius r decreases. With the same muscle force, a greater angular acceleration can be obtained!

This allows the arm to swing more quickly!

Provides greater initial acceleration for the start!

Immediately after going out.

Four steps of gold.

During the start stage of starting, the female body structure with a low center of gravity combined with the starting of a bent arm can achieve efficient transmission of strength.

When Chen Juan pushes the ground with her feet to produce a back pedal force, the low center of gravity allows the body to more stably transmit this force along the central axis of the body.

at the same time.

The rapid swing of the curved arm can generate a forward and upward pulling force, which cooperates with the pushing force of the lower limbs to form a more coordinated joint force direction.

This direction of force is closer to the direction of the body's movement, reducing the decomposition and loss of force during the transmission process.

Enables more power to be effectively used to push the body forward.

Of course it's faster!

At the same time, there is an additional discovery, that is, the posture of low center of gravity and the starting movement of the bent arm require specific neuromuscular control modes.

In a research report at Sushen Laboratory, it is stated-

In this case, the nervous system can more accurately activate the muscle groups involved in the starting lineup.

Including the quadriceps femoris, gluteus maximus, upper limb deltoid muscles, pectoralis major muscles, etc.

Under the coordinated control of nerves, these muscle groups can contract in a more coordinated order and force.

Improves muscle productivity.

This will generate greater explosive power at the moment of starting.

Enable the body to quickly get rid of the state of static.

Obtain a faster initial speed.

That……

How can you not be happy?

There is really no opponent in the country.

It is difficult to get along well in actual combat.

Finally moved to the international competition.

Chen Juan can show her skills!

After going out ten meters.

It's the acceleration zone.

Taking advantage of the female body structural characteristics, the gender characteristic of its relatively low center of gravity and closer to the central axis of the body.

More than just startup.

Acceleration zone.

It will also be more powerful and outstanding.

Like this one you see now.

Bang bang bang bang bang bang bang.

Chen Juan took advantage of the advantages of low center of gravity and curved arm starting in the acceleration stage to continue the effect.

After entering the acceleration phase, the advantages of low center of gravity and bent arm start are still significant.

A low center of gravity can continuously maintain the stability of the body, allowing athletes to better control their body posture during the acceleration process and avoid excessive fluctuations or deviations in the center of gravity caused by increased speed.

At the same time, the kinetic energy brought by the curved arm can provide the body with additional forward thrust, and through reasonable adjustment of the rhythm and amplitude of the swing arm, it maintains good synchronization with the acceleration and thrust movement of the lower limbs.

This coordinated cooperation between upper and lower limbs can effectively maintain the body's acceleration and enable the speed to be continuously and rapidly increased.

Bang bang bang bang bang bang bang.

"Chen is too fast?! Is this the startup acceleration that a big-size girl should have?"

"She's like a big-size fighter!"

This explanation is very beautiful.

But some people are dissatisfied with it after hearing it.

"Large size girl?"

"Your whole family is a big size girl!"

"My sister Juan is called tall and thin!"

"I know nothing!"

This was naturally what Zhou Bing said.

His current ability to protect his calf.

Not ordinary.

Chen Juan continued to accelerate.

Twenty meters later.

From the perspective of energy metabolism!

The combination of low center of gravity and curved arm start can also help optimize energy consumption.

A low center of gravity reduces unnecessary ups and downs of the body in the vertical direction.

Reduces the energy consumed to overcome gravity.

The optimization of the movement also reduces the distance of the arm swing and air resistance, thereby reducing the waste of energy.

This allows Chen Juan to use more energy to accelerate the body during the acceleration process.

The energy utilization efficiency is improved, and maintaining high-speed running provides energy and is also guaranteed.

That……

How can you not be happy?

Bang bang bang bang bang bang bang.

Shooting on the way.

Chen Juan's overall speed surged.

When running on the way, the center of gravity of your body is stable.

The stride is always kept in a large state, and the pace is light and elastic.

Bang bang bang bang bang bang bang.

Speed ​​zone.

Chen Juan can move forward efficiently with the reaction force of the runway every step.

All parts of the body cooperate with each other.

Just like a precision instrument running at a high speed, it can continue to run at a stable and high speed state.

Don't give your opponent any chance to overtake.

Firmly control the rhythm of the game.

Entering the second half of the speed stage.

Further explore the potential of leg muscles.

The power to push the ground has reached a higher level.

The arm swinging movement is more rapid and powerful, driving the overall speed of the body to a higher peak.

During this stage, Chen Juan continued to consolidate her lead.

Leave the other players far behind.

Step steadily towards the throne of champion.

No Brown.

No Fraser.

Jetel, the number one sister who does not have Amika.

It's really running.

That was so relaxed and pleasant.

The air is fresh.

The person behind.

I haven't known where I've been.

No one wants it.

A year after the Olympics.

Some people are so fierce as soon as they come up.

...

"Chen Juan has established a huge lead. If you don't know, you think this is some domestic competition!"

"Chen Juan has a bright smile!"

"Easy to cross the finish line!"

“Not even pressing the line!”

“10.85!!!”

"Another result within 10.90!!!"

"Chen Juan's second career score of less than 10.90s was achieved!"

"Looking at how she can still cross the line with a smile on her face in the end, can we conclude that she actually has enough energy?"

"I'm really looking forward to her game later this year."

How can it not be strong?

You have to know the wind of this game.

Only 0.4 meters per second.

in this case.

Her results in this shot may not be weaker than the one she won the bronze medal in the Olympics.

Because the wind speed of that shot was as high as 1.5 meters per second.

As for the rest.

I'll just say something to you like this.

Jamaican Arlene Bailey, the women's 100m champion in this Diamond League in history.

The only result in winning the championship...

11 seconds 37.

Think about the rest yourself.

On the sidelines.

"Hey."

"Look, another champion."

"We are no longer spectators in the Diamond League."

"turn out to be……"

"It feels like watching your athletes harvest various championships in international competitions, especially the harvest of multiple events."

"It's so good."

"Who said no?"

Yuan Guoqiang was also a big-mouthed girl, and he was about to come out.

"The feeling of waiting for a champion until the end of the day is already a thing of the past."

“This year is like what Xiaotian said.”

"we."

"Be the champion reaper."

“Medal harvester for major competitions.”

This is said before the winter training.

It's somewhat exaggerated.

A strong project is only 100 meters.

If you want to be a harvester, a project is not strong enough.

If you want to show your face in the Diamond League, you have multiple events to win the championship.

Let's see now.

The time difference is just right.

The champions were harvested one by one.

Athletes gain both fame and fortune.

These are the coaching team members.

The same is true.

2013.

Flower Planter Track and Field Team.

Start tasting for the first time.

The pleasure of harvesting in international competitions.

Has the first time.

People will want to have a second time.

Su Shen wanted to cultivate such inertia.

In that way, there will be a steady stream of good results.

Break through this zero.

1~100.

It's often much easier.
