It is said that anyone who can practice the long jump well can master the knowledge of parabola.

So, is this a math problem or a physics problem?

When it comes to the trajectory of a parabola, in fact, this is not a simple college entrance examination question that can be solved.

It is also necessary for a graduate student majoring in pneumatics to conduct an analysis of the structure of the airflow, and then find out in what state and at what initial speed in order to obtain a longer jump distance.

Chen Mingliang has a professional coach to guide, now whether it is running, taking off, or the action after taking off, as well as the connection of various movements after landing, the coordinated movements that should have have been mastered well, and the only thing lacking now is the test of actual combat.

Athletes in the 100-meter sprint are talented in the long jump. Even if you haven't practiced once, it's easy to jump a distance of more than 6.5 meters, so just try to jump and cross 7 meters. x :/m.x/

The reason why so many track and field athletes don't practice the long jump is not because they can't practice well, but because the long jump is too niche.

It's even more niche than rice.

Generally, the speed ability of long jumpers is still good, and some members of the provincial relay team are mainly practicing long jump.

In fact, the direction of domestic training is a bit off, and the first choice of good seedlings with good speed ability and strong explosive power in China is not to practice track and field, but to practice weightlifting.

Add a little fierce material when training, and wait until the weightlifting results are domestically dominant, and it is not worthwhile to go internationally.

No matter how good track and field training is, you can't even dominate Asia.

Therefore, our good seedlings first went to practice weightlifting, then to practice shot put, then to practice long jump, and finally they really couldn't do it, so they would come back to practice track and field.

In the studio, sports enthusiast Liu Fei and CCTV host Yang Jian are discussing Chen Mingming's long jump performance.

Don't look at Liu Feiren's current major is hurdles, in fact, he practiced long jump when he was a child.

"What do you think of Chen Mingming's long jump ability?" Yang Jianzai and Liu Feiren sat there chatting.

"I think it should be very good, Chen Mingliang has always been not a sure fight, as the world's first sprinter, he has too much advantage over others in practicing long jump." x www.x m.x

"Do you think he can win the championship?"

"It's hard to say, there are not many good players in China, there are several players who have jumped 8 meters, and I was practicing long jump at that time and I really couldn't see hope, so I turned the hurdles."

。。。。。。

"Okay, now that Chen Mingliang has appeared, looking at his expression, he is full of confidence. Look at his action, he knows the routine very well, this is asking the audience to applaud. ......”

Chen Mingliang really shook his head and appeared, and he also measured his starting point with the number plate, looking like he was in trouble. The start begins!

"This running rhythm is so beautiful!." Liu Feiren couldn't help but praise.

Chen Mingming's running is really fantastic, first come back to a back, then take small broken steps, and then accelerate forward, the pace is faster and faster, and the speed is so fast that it flies.

He should run fast, after all, as the world record holder of the men's 100 meters, so in terms of instantaneous running speed, there are not many sincere people who can run faster than Chen Mingming.

Running is the basis of jumping, and without good speed ability, it is difficult to be able to jump far.

Chen Mingliang ran faster and faster, and his speed had increased to the fastest, and then he stepped on the pedal and took off!

"Look at this vacant height!" Liu Feiren is knowledgeable, and through this vacant height, you can judge Chen Mingliang's performance in this jump, which is obviously better than others!

Chen Mingming's movements after taking off are also very chic, which is the so-called air walk.

After taking a few steps, he made a gesture of landing with his legs as far forward as he could.

After completing a set of movements, Chen Mingliang landed at the very end of the speed, and then his body fell forward.

"Chen Mingliang jumped so far, is this over the 9-meter line! Is this over the 9-meter line? From the TV broadcast camera, we seem to see that Chen Mingming's final landing point has passed 9 meters, could it be that his first jump went to the world record, which is also incredible! Yang Jian spoke incoherently excitedly.

"It's amazing, it's amazing!" Liu Feiren also exclaimed again and again.

The audience at the scene was also excited, some people had a better vision, and they could see that Chen Mingliang jumped a long distance, which is too good!

As soon as Chen Mingliang finished jumping, the audience suddenly "Wow! There was applause, and there was the sound of a whistle.

Then, at this moment, the referee who came out of the springboard raised a small red flag, "Foul on the line!" -->>

[Reading updates load slowly, there are ads, chapters are incomplete, please exit Reading and read!] 】

”

"Alas", there was another sigh from the scene.

Even the referee couldn't bear to miss such a good result, so he still asked the staff to take a tape measure and measure it, and the result was 9.02 meters, which was really over 9 meters!

At this time, the TV also gave slow motion, and the slow motion showed: Chen Mingliang stepped on the line at the moment of jumping, and it was about 2 centimeters to cross the line, that is to say, if it wasn't for Chen Mingliang's foul, it was really possible for him to break the domestic record and Asian record in the first jump of his career.

"It's a pity, it's a pity, it's such a good box." It seems that the Tangshan dialect came out of nowhere, it turned out to be from Yang Jian's mouth, and it seems that he also likes Brother Dao in the stone.

When Chen Mingliang jumped, he felt that he was in a very good state, he felt very natural, and his movements were also very stretched, but he didn't expect to step on the line in the end.

There were too many competitors participating in the long jump, and it was already half an hour later when Chen Mingliang arrived in the second round.

In the past half hour, Yang Jian and Liu Feiren have been discussing what would happen if Chen Mingliang didn't step on the line, Chen Mingliang's physical talent was too powerful.

Chen Mingliang does not live in a vacuum, he knows that most of the audience came to watch the game because of him, so he did not go back to rest, but interacted with the audience, he was like a champion, going around the stadium and mingling with the audience.

Look, that's popularity!

Finally, it was Chen Mingming's turn to make the second jump, and he re-measured the step point and prepared for the second attempt.

Chen Mingming's small broken steps were reversed again, ready to come to the second shot, this one seemed to be in better physical condition than the previous one.

The surrounding audience held back their breath and watched Chen Mingliang make preparations, his expression was also very serious, and his temperament was cold, just like the Chen butcher in the slaughterhouse.

This is a powerful temperament, a kind of king confidence!

Chen Mingliang glanced at the sand pit in the distance, and then began to gradually accelerate, super large pace, extremely fast speed, this is the speed that belongs to the world record, this is the glory of a world champion!

Chen Mingliang stepped on the springboard again, like an antelope crossing a cliff, flying in the field!

Another perfect movement, stretched and graceful.

"Perfect!" The good words have all been finished by Yang Jian and the others just now, and when it is their turn, they are already a little short of words, and if they continue to talk about it, they can only make leftovers.

Chen Mingming's jumping movements are as crisp and neat as the entry of the little prince of diving, and they are all perfect perfect movements that do not see a splash when entering the water.

Chen Mingliang put his feet into the ground, then squatted, and fell forward by inertia, ensuring that the point of entering the soil was the farthest point where his body touched the ground, which he understood and practiced.

Sure enough, another perfect result!

Judging from the TV screen, Chen Mingliang crossed the 9-meter line again, and when the domestic athletes were still struggling on the 8-meter line, Chen Mingliang had already touched the pulse of 9 meters. (The first launch, the domain name (remember _ three < three ^ small" said (net) W, ω, ω@.x, 彡, 彡, x'¥[email protected], o-м text) < more ¥ new / speed ¥ degree the most & 駃 = 0

This time, the referee was silent for a long time, and did not raise the red flag, nor did he raise the white flag to indicate the passage.

What's going on?

After a while, the referee still raised the red flag and stepped on the line again!

TV slow-motion reality, Chen Mingming's toes touched a little bit of reticle, only a few millimeters away, it's a pity.

The surveyor knew what everyone cared about, so he went to measure Chen Mingming's long jump data, 9.04 meters, almost tied the world record!

The audience naturally sighed again, and everyone was waiting for Chen Mingliang to come over and interact.

But he didn't move, just sat in the athletes' rest area, probably a little tired.

Actually, it's not that he's tired, it's that he feels his shoulder hurt again.

Chen Mingliang stood up, walked to the coach's area across the guardrail, thinking that the coach pointed to his right shoulder, and the coaches immediately knew, and then shouted "Quit!" Retire! ”

The nearby audience was happy to see Chen Mingliang, and they were very angry when they heard someone shouting to quit the game, and turned their heads to see that it was more and more a foreigner with a few coaches, this Nima is Chen Mingliang's coaching staff, he won't really want to retire again.

Why add another word?

With a decision, Chen Mingliang found the referee on duty and said that he would not jump and retired from the game.

The referee was also surprised, "You're retiring again!" The two red flags are not aimed at you, you don't have to worry, according to your results, you are the first person in the country who deserves to be on duty! ”

Chen Mingliang said that he had a sore shoulder blade and had to retire from the injury.
