The Su God of the Reopening of the Sports Arena

Chapter 2096: Champions meet again! The era of spectators... is over

Xie Zhengye 19.83s.

the first.

Warren Weir 20 seconds.

second.

Edward 20.38s.

third.

American athlete Jeremy Dodson ran 20.68s.

fourth.

Ramon McKenzie of Jamaica 20.77s.

fifth.

Curtis Mitchell 20.77s.

sixth.

……

You will understand once the results come out.

The overall level of sprinting this year has declined compared to last Olympic year.

And the decline is not just a little bit.

Before the game, Xie Zhengye was so excited that he wanted to blow up all the opponents.

How do you know?

It really came true.

He also ran a personal career best.

With a wind speed of 0.9 meters, I wish you couldn't escape.

There's nothing we can do about it.

These people looked at Xie Zhengye who seemed somewhat dissatisfied.

For a moment, I was so embarrassed that I couldn't speak.

I don’t know what to say.

Or it shouldn't be said.

The atmosphere in the waiting area.

Long before Xie Zhengye's achievements.

He was beaten to pieces.

The rooster couldn't even lift his head.

Then it was time for the final 100-meter race to begin.

First up is the women's 100 meters.

Chen Juan and Wei Yongli took the stage together.

There is just a Taoist priest in the middle and the ninth one on this side.

There is no way around this.

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

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

It's fine to place it in the center.

Wei Yongli had no choice but to stay on the sidelines.

However, she already knew the answer to this question, and she knew that she had to rely on her own strength to achieve everything.

She has basically achieved nothing internationally now.

It's very reasonable to arrange it here.

Anyway, our Asian-level results are simply not good enough on the international stage.

There's no point in taking yourself too seriously.

You need others to take you seriously.

Otherwise, no matter how good or how many achievements you achieve in Asia, you won't have much presence on the international stage.

this problem.

Wei Yongli had said this to Chen Juan a long time ago.

Because these were all Chen Juan’s own feelings back then.

Even though Chen Juan has reached this position now, she has gone through all of these experiences.

Taste them all.

First course: Sironi Calvert-Powell.

The second one is Jessica Young Warren.

The third course is Jamaican Brown.

The fourth one is Chen Juan.

Fifth Lane Arlene Bailey.

Lane 6 Mikel Barber.

The seventh is Lakeisa Lawson.

The eighth is Tiana Bartoletta.

The ninth one is Wei Yongli.

The situation is similar to the 200-meter one.

They are all the same, either American or Jamaican players.

It has been like this for many years.

Only.

Don't know when it started.

In these melees between the Jamaican and American teams, more and more yellow figures gradually appeared.

Everyone will definitely not be used to it at the beginning.

But it's been several years.

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

Now even America's audience.

The so-called noble American spectators.

We are slowly adapting to this.

Whether active or passive.

Everyone has to adapt.

"Well, we can see that the American team did not send out their strongest seeded players."

"It seems that after the Olympic year, everyone is taking a good rest and recuperation."

"This is also very normal, especially in track and field sports, which are very physically demanding. After the Olympic year, it is normal to let the body relax and take time to recover."

"Of course the U.S. team is still very strong."

“We can see that we can still attract a lot of people 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 making a buzzer beater against Brown."

“I wonder if it can be replicated this time.”

In fact, Brown himself didn't want to hear what Yang Jian said.

Because such video clips and dynamic screenshots are very common on the Internet.

With the advent of the mobile Internet era.

The number of people using the Internet has increased exponentially compared to before.

That's about various secondary creations.

It will also soar.

The scene where Brown was killed by Chen Juan's breast.

The screenshot is both classic and funny.

And this for Brown himself.

It's no less than secondary injury.

Losing the game and being defeated was depressing enough.

The results will be seen on the Internet.

People joked that she lost because her breasts were not big enough.

What do you think.

Damn the rules of athletics.

Why only look at the torso?

My breasts can only grow this big, so it’s my own fault.

You think Brown doesn't want to grow bigger?

You don’t have this ability, you know?

And girls use this for comparison.

It's somewhat embarrassing.

The key point is that we lost to an Oriental.

I don’t know if it was enough for Brown to win the 200m championship, or if there were other reasons…

It is actually the same as the original historical line.

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

This stunned Chen Juan who was warming up.

Not sisters.

Why don't you run away?

I saw you were fine just now, weren't you?

When Chen Juan saw Brown raising his hand to withdraw from the competition, she walked over to show some concern and asked Brown if he had caught a cold because of the chest pain.

But this time.

"Chest", this word.

It's like a sensitive taboo word.

Brown felt a chill when he heard it.

He left with a dark face.

Not a word was lost.

Of course she was dark enough.

Chen Juan: ???

What's happening here?

Why does it seem like I've offended her by showing my good intentions and concern for her?

Ugh.

These European and American sisters.

It's really difficult.

Brown's withdrawal from the game is just a minor episode. The game will not stop because of one person.

After the referee called the game Brown was out.

The rest of the group got ready again on the runway.

A battle of 8 people.

Get ready to start again.

set.

boom----------

Jamaica's Shiloni Calvert-Powell has amazing explosive power when she pushes off the ground with both feet. The angle of her push back is about 45 degrees, which can efficiently convert force into initial forward velocity. She pushes her hands off the ground cleanly, lowers her head, and leans forward at a moderate angle.

Her teammate Arlene Bailey takes a safe approach by pushing the ground with both feet with moderate force when starting. After pushing her hands off the ground, she leans forward at a reasonable angle and smoothly enters the acceleration phase.

American athlete Mikel Barber had a very quick reaction time at the start, with a reaction time of only 0.135 seconds, and then he pushed off the ground with both feet cleanly, pushed his hands off the ground quickly, and leaned forward in time.

Get a faster initial velocity right from the start.

She wanted to establish a strong advantage right from the start.

Give yourself some buffer space.

pity……

There is a Chen Juan here.

Chen Juan has mastered the bent-arm start.

Unless Fraser is here.

otherwise.

These people are not evenly matched with my enemy.

During this year's winter training, she had plenty of time, so she started the bent-arm start again.

She really found a lot of feelings...

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

Around this point, the entire team began to upgrade the technology.

From an anatomical point of view, women have relatively wider pelvises than men, and the skeletal structure of their lower limbs also differs in shape and proportion, which makes the center of gravity of women relatively lower and closer to the central axis of the body when they are standing naturally.

This center of gravity distribution characteristic is determined by the physiological structure of women. During exercise, especially at the start of a sprint, it will have an important impact on the body's stability and force transfer.

This means that the distribution of the center of gravity needs to be modified to suit women's characteristics compared to men.

Then based on this, 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 moment of starting, women's lower center of gravity can provide greater stabilizing torque.

This makes it less likely for the body to experience instability such as excessive forward leaning or sideways when it is subjected to the strong backward force and forward momentum at the start.

This can lay a solid foundation for the subsequent acceleration process, reducing energy loss and speed loss caused by unstable center of gravity.

Based on these scientific points, we can start to fine-tune and change the technology.

Compared with the previous bent-arm start, Chen Juan now makes adjustments before starting. For example, before the bent-arm start, she bends her arms and keeps her elbows closer to the sides of her body than last season!

This posture reduces the arm swing radius, allowing the arm to swing faster when starting, and the direction and strength of the swing are easier to control.

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

This is also the primary habit of modern athletics.

If we continue to rely on empiricism as before, we will only fall further and further behind.

In other words - during Chen Juan's training and competition, high-speed cameras were used to film her starting process from multiple angles, including the front, side, and overhead.

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

In conjunction with electromyographic signal monitoring, which uses a surface electromyograph (SEM), electrodes were attached to the anterior, middle and posterior bundles of Chen Juan's deltoid muscles, as well as her chest and arms, such as the biceps and triceps. The electromyographic signals during the starting process were collected with a sampling frequency of 2000Hz to analyze the degree of muscle activation and force characteristics.

Then, a force plate launched by Su Shen Laboratory was installed under the starting block to measure the force, direction and duration of Chen Juan's feet pushing the ground when she started. The sampling frequency of the force plate was 1000Hz, so as to evaluate the force effect of the lower limbs at the start and its coordinated relationship with the upper limb movements.

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

Then through calculation, we can find out that...the moment of inertia of the arm when starting in this way is reduced by about 25% compared to last season!

Calculations based on a simplified human arm model, assuming that the arm is a uniform thin rod, use the moment of inertia formula. When the muscle torque output remains unchanged, the reduction in moment of inertia enables the arm to obtain a greater angular acceleration, thereby achieving a faster swing speed.

Combined with the electromyographic signal analysis, the average electromyographic amplitude of the anterior deltoid muscle of Chen Juan's shoulder reached 4.8mV when she started the race, which was an increase of 4.2% compared with 14.29mV last season; the average electromyographic amplitude of the pectoralis major muscle increased from 3.5mV to 4.1mV, an increase of 17.14%.

This indicates that the adjustment of the elbow enables the relevant muscles to be activated and work together more effectively when starting. As the arm swing radius is reduced, the muscle contraction stroke is relatively shortened, and the muscle can reach the maximum contraction force faster in the same time, thereby improving the muscle's force efficiency.

At the same time, the direction of muscle force and the direction of arm swing are more consistent, which reduces the decomposition and loss of force and allows more muscle strength to be directly used to push the body forward.

The force plate test data showed that Chen Juan's average horizontal force component when pushing off the ground with both 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 swinging of the upper limbs can generate a forward and upward pulling force, which, through the body's musculoskeletal conduction system, cooperates with the forward and downward thrust generated by the lower limbs pushing off the ground.

This makes the direction of the resultant force acting on the body at the start closer to horizontal and forward, thereby further improving the acceleration performance at the start.

After rigorous analysis of the data, we can draw the following conclusion:

Scientific research analysis of Chen Juan's adjustment of her starting posture showed that the change of bending her arms and bringing her elbows closer to the sides of her body before the bent-arm start brought significant improvements in arm swing speed, muscle activation and force, and starting acceleration performance.

This is consistent with the argument that the characteristics of women's body structure determine that their center of gravity is relatively low and closer to the central axis of the body.

That is what you see now.

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

This allows the arms to swing faster!

Provide greater initial acceleration for starting!

Immediately after going out.

The four golden steps.

During the starting phase of a race, women's low center of gravity body structure combined with the bent-arm start can achieve efficient transfer of force.

When Chen Juan pushes the ground with her feet to generate backward force, the low center of gravity allows the body to more stably transmit this force upward along the central axis of the body.

Simultaneously.

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

The direction of this combined force is closer to the direction of body movement, reducing the decomposition and loss of force during the transmission process.

This allows more force to be effectively used to propel the body forward.

Of course it’s faster!

An additional finding was that the low center of gravity posture and bent-arm start movement require specific neuromuscular control patterns.

According to the research report of Su Shen Laboratory:

In this case, the nervous system is able to more precisely activate the muscle groups involved in the start.

Including the quadriceps and gluteus maximus of the legs and the deltoid and pectoralis major of the upper limbs.

These muscle groups, under the coordinated control of the nerves, are able to contract in a more coordinated sequence and force.

Improves muscle working efficiency.

This will generate greater explosive power at the start moment.

Enables the body to quickly get out of a static state.

Get a faster initial velocity.

that……

How can it not be fast?

There is really no rival in the country.

It is difficult to perform well in actual combat.

Finally, it was time for an international competition.

Chen Juan can now show her skills!

After ten meters.

It's the acceleration zone.

The female body structure characteristics determine that her center of gravity is relatively low and closer to the central axis of the body, which is a gender characteristic.

More than just startup.

Acceleration zone.

It will also be more powerful and outstanding.

Just like what you see now.

Bang bang bang bang bang.

Chen Juan took advantage of the low center of gravity and bent-arm start to maintain the advantages during the acceleration phase.

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 acceleration and avoid excessive fluctuations or shifts in the center of gravity caused by increased speed.

At the same time, the kinetic energy brought by the bent arms can provide additional forward thrust for the body, and through reasonable adjustment of the arm swing rhythm and amplitude, it can maintain good synchronization with the accelerated ground-pushing action of the lower limbs.

This coordination between the upper and lower limbs can effectively maintain the body's acceleration, allowing the speed to continue to increase rapidly.

Bang bang bang bang bang.

"Chen is too fast?! Is this the starting acceleration a plus-size girl should have?"

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

This explanation is very American.

But some people were not satisfied after hearing it.

“Plus size girls?”

“Your whole family is made up of plus-size girls!”

"My sister Juan is tall and skinny!"

"You know nothing!"

These words were naturally said by Zhou Bing.

He now has the ability to protect his children.

Not ordinary.

Chen Juan continued to accelerate.

Twenty meters later.

From the perspective of energy metabolism!

The combination of a low center of gravity and a bent-arm start can also help optimize energy expenditure.

A low center of gravity reduces unnecessary vertical movement of the body.

Reduces the energy consumed to overcome gravity.

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

This allows Chen Juan to use more energy for horizontal acceleration of her body during the acceleration process.

The efficiency of energy utilization is improved, and the energy provided to maintain high-speed running is also guaranteed.

that……

How can it not be fast?

Bang bang bang bang bang.

Taken on the way.

Chen Juan's speed increased rapidly.

When running, keep your body's center of gravity stable.

The stride is always kept large, and the steps are light and elastic.

Bang bang bang bang bang.

Speed ​​zone.

It seemed as if Chen Juan could use the reaction force of the runway to move forward efficiently with every step.

All parts of the body work in perfect harmony.

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

Don't give the opponent any chance to overtake.

Firmly control the rhythm of the game.

Entering the second half of the extreme speed stage.

Further tap the potential of your leg muscles.

The power of pushing off the ground is taken to a new level.

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

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

Leaving other players far behind.

Steadily moving towards the championship throne.

No Brown.

No Frasier.

There is no Amelica's sister Jeter.

Really running.

It was such a relaxing and enjoyable experience.

The air is fresh.

The person behind.

I don't know where it went.

No one could have imagined it.

The year after the Olympics.

Some people are so fierce right from the start.

……

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

"Chen Juan with a bright smile!"

“Cross the finish line with ease!”

“It didn’t even touch the line!”

"10.85!!!"

“Another score under 10.90!!!”

"Chen Juan achieved her second time under 10.90 seconds in her career!"

“Since she was able to cross the finish line with a smile on her face, can we conclude that she still has some energy left?”

“I’m really looking forward to her competition later this year.”

How could it not be fierce?

You have to know the wind of this game.

Only 0.4 meters per second.

under these circumstances.

Her result with this shot is probably not worse than the one that won her the bronze medal in the Olympics.

Because the wind speed of that shot was as high as 1 meters per second.

As for the rest.

Just saying this to you.

The champion of the women's 100m in the Diamond League in history is Jamaican Arlene Bailey.

The only winning result is...

11 seconds 37.

The rest is up to you to figure out.

On the sidelines.

"Hey."

"Look, another champion."

"Diamond League, we are not spectators anymore."

"turn out to be……"

“It feels great to see our athletes win various championships in international competitions, especially in multiple events.”

“It’s so cool.”

"Who says it isn't?"

Yuan Guoqiang also had big teeth, and they were about to show out.

"The feeling of waiting forever for a championship is a thing of the past."

“This year is just like what Xiao Tian said.”

"we."

"To be the champion harvester."

“A medal winner in all major competitions.”

This was said before winter training.

It's somewhat exaggerated.

The only strong event is the 100 meters.

If you want to be a reaper, being strong in one project is not enough.

If you want to make a name for yourself in the Diamond League, you should at least win multiple events.

Let’s look at it now.

The time difference is just right.

Champions were harvested one by one.

Athletes gain both fame and fortune.

They are the coaching staff.

The same is true.

2013 years.

The Flower Planters Track and Field Team.

Started tasting for the first time.

The thrill of reaping all the rewards in international competitions.

There was the first time.

People will want to have a second time.

Su Shen wants to cultivate this kind of inertia.

Then good results will start to appear in a steady stream.

Breaking through this zero.

1~100.

It is often much easier.

ps: More updates added!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Please give me votes, hehe!!! ...

Big guys, charge! ! ! ! ! ! ! ! ! ! !
