In the men's high jump, what is the difficulty of 2.30m?

Last year, in 2012, only one Chinese male athlete jumped more than 2.30m in an official competition, and that person was Zhang Guowei, who set a time of 2.31m.

With a score of 2.31 meters, Zhang Guowei went to London to participate in the Olympic high jump competition, and the A standard score of the men's high jump at the London Olympics was 2.31 meters.

In the men's high jump final of the London Olympics, Russia's Ivan Yukov won the championship with a score of 2.38m, the second place with a score of 2.33m, and the third place with a score of 2.29m.

From the above data, we can see that the third place in the Olympic men's high jump final did not cross the height of 2.30m, so 2.30m is not so easy to conquer.

This data also shows that the high jump competition attaches great importance to state and on-the-spot performance, the London Olympics men's high jump A standard is 2.31 meters, and the men's athletes from all countries who can participate in the men's high jump competition at the London Olympics have made a score of 2.31 meters (a small number of players have registered for the competition with a score of 2.28 meters in the B standard), but in the final, only Russia's Ivan Yukov and the United States' Kenard jumped 2.31 meters high, and the rest of the players were all stuck below 2.29 meters and could not exceed 2.30 meters.

Including Zhang Guowei, he went to London to participate in the high jump competition with a registration score of 2.31 meters, but he failed to jump 2.25 meters in three attempts in the qualifying round, and did not even enter the final.

Zhang Guowei was ashamed and brave, and he performed well this year, jumping 2.32m in the indoor competition in March. Wang Yu is not far behind, he jumped 2.30m in the National Track and Field Grand Prix in the first half of this year.

In fact, in this year's official competition, only Zhang Guowei and Wang Yu have made a height of 2.30 meters or more among the domestic men's players.

That's how difficult it is to 2.30 meters.

Wang Yu failed to jump 2.30 meters high for the first time, he shook his head, and returned to the standby area with some disappointment.

"Whew, whew, whew." Du Ke exhaled three times in a row, adjusted his state to a little excitement, and then hung his [eagle's wings] and began to run.

It was still a flat slash, and he didn't open the active stunts [Fast Frequency Assault] and [One Step to the Sky], and Duke jumped.

Vacating, passing the pole, and compensating for the adjustment, Du Ke's pole crossing action is relatively in place, but unfortunately, his hips touched the pole, the pole fell, and the first attempt failed.

Duke shook his head after the mat, not quite satisfied with the attempt.

Zhang Guowei appeared for the third time, he saw that Du Ke and Wang Yu's first attempt to jump 2.30 meters was unsuccessful, he was energetic and excited, if he could take away 2.30 meters in a wave, wouldn't it be very hanging?

Before running, Zhang Guowei suddenly made a set of movements, he stretched out his arms, faced the spectators, and rhythmically raised his arms, once, twice, three times...... He made a "lifting" gesture and asked the audience to cheer him on and give him encouraging applause.

Every time Zhang Guowei raised his arms, he was accompanied by exaggerated expressions and slogans, "come", "come", "oh oh......

Therefore, Zhang Guowei, who is 2 meters tall, is known as "chic brother", and his style of competition is indeed free and easy, and there is some publicity in it.

The audience also cooperated with Zhang Guowei's chic demeanor, and began to applaud rhythmically, papa, papa...... More than 50,000 people, rhythmic popping, very hilarious and hot pictures. No matter how simple the action is, tens of thousands of people make it in unison, and its shock is difficult to describe in words.

Zhang Guowei saw that the atmosphere of the scene was almost in place by him, and suddenly flipped his palms, palms down, and made a downward gesture, signaling to the audience: "I'm ready to hang the sky, please be quiet for a while, and watch my show-time!" ”

The audience seemed to be keen on this kind of live play, and sure enough, they stopped applauding and making noise, and began to quietly watch the chic brother pretending.

Zhang Guowei faced the crossbar position, looking confident, ready to run, "It's only 2.30 meters, after February this year, I can often jump this height, small case." ”

Zhang Guowei began to run, walking the J-shaped curve, he took the last step, and jumped with full strength, his vertical speed is very fast, and he has a strong jumping force!

Vacating, crossing the pole, raising his head, and inverting his shoulders, his set of pole movements were done neatly and neatly, without any mud and water.

After landing on the mat, Zhang Guowei took advantage of the situation to roll over quickly, half-knelt on the cushion, and immediately looked at the crossbar position.

The crossbar is still in place, haha, it worked! A wave of streams!

Zhang Guowei died of hi.

Wait a minute!

Damn, why is this pole still shaking?

Although the crossbar did not hit the ground, it did shake slightly, swaying, shaking, shaking, and then ...... The pole is down.

"Leaning on the ......" Zhang Guowei hit his head on the cushion, annoyed and wanted to vomit blood, obviously a perfect run, jump, and pole, which link went wrong? What part of the body rubbed against the pole?

"Huh~" The audience also felt sorry for Zhang Guowei.

Some viewers also began to ridicule: "Brother Chic, let's be embarrassed, I will give you full marks for your pretending to be forced to jump, but I can only give you 80 points for the subsequent game actions." ”

Zhang Guowei returned to the standby area with an unhappy face and did not say a word. He is still struggling with his first jump at the moment, what went wrong? There's no reason to hit the pole?

At this time, Wang Yu appeared again, ready to hit the height of 2.30 meters for the second time. Run-up, take-off...... Shot down, he failed again, worse than the first jump.

After failing in the first attempt, Wang Yu was disappointed, but he was still able to meet the second attempt with a smile.

After the failure of the second attempt, Wang Yu could no longer laugh, he had been forced to the edge of the cliff, and there was only one last chance to try the jump, a life and death jump.

Compared with Zhang Guowei's entanglement and entangled in where the problem of his first jump was, after Du Ke failed to jump for the first time, he knew very well what his problem was.

It's okay to run, it's okay to jump, and in terms of pole passing skills, I've done the best I can, so what's the problem?

The problem: the vertical velocity is not enough.

Duke felt that if the vertical speed was a little faster, he should be able to cross 2.30 meters.

Increasing the horizontal speed of the run-up and strengthening the take-off force are all aimed at maximizing the vertical speed, that is, increasing the vertical height of the take-off jump.

High jump, the higher the jump, the more advantageous, under the premise that the jump height is guaranteed, the pole crossing skills can be exerted to the extreme.

Jumping 2.30 meters high, if the athlete's body center of gravity can only reach 2.20 meters, then he is a technical master and useless, that's the reason.

To cross the height of 2.30 meters, athletes take the back-to-back high jump method, and the height of the center of gravity of the body after taking off must reach at least 2.35-2.40 meters. It's easy to understand that if you want to cross the bar, the vertical height of your body's center of gravity must be higher than it.

Through the first attempt to jump 2.30 meters high, Du Ke deeply felt the difficulty of this height, under his current attribute conditions of 479, hanging eagle halo flat cut, may jump seven or eight times to successfully pass the pole once, 2.30 meters is definitely an international height.

In the men's high jump final, Duke didn't have seven or eight chances to hit the height of 2.30m, in fact, he only had two chances left.

Duke came out at this time, ready to try the second jump of 2.30m, and he looked at the time on the big screen: 19:51.

With enough time, Douc decided to turn on the [Fast Assault] run on the second attempt to increase his horizontal speed. Now open a [fast frequency assault], and after 20:51 (+1~2 minutes), you can open it again, which can correspond to the men's 100m final that starts at 21 o'clock.

Why don't you open [Fast Frequency Assault] + [One Step to the Sky] together?

Because Du Ke wants to keep one hand, double open [fast frequency assault] + [one step to the sky], Du Ke is more than 99% sure that he can cross 2.30 meters, but if one or both of Wang Yu and Zhang Guowei cross 2.30 meters, how should the height of the back correspond?

In fact, the most difficult to deal with is Zhang Guowei, because Wang Yu played in front of Du Ke, Wang Yu will complete three test jumps before Du Ke, and Du Ke can play cards to deal with Wang Yu.

In the same way, Zhang Guowei, who appeared last, can also play cards to deal with Du Ke and Wang Yu.

Therefore, when playing high jump is of equal strength, you still have to pay attention to tactics.

"3,2,1......" Duke silently counted down from the starting position about 30 meters from the bar, staring at the bar 30 meters away, his eyes flashing with a desire to conquer.

"Suddenly!" Duke started to run, and turned on the [Fast Assault] to speed up.

His initial starting speed was impressive, not much slower than the initial speed of the 100-meter race.

Eight steps later, Duke began to lean in and arc, and after taking the twelfth step, he jumped!

The fast run-up brings additional horizontal velocity and horizontal kinetic energy, and at the moment of take-off, part of the horizontal kinetic energy is converted into vertical kinetic energy, plus the direct vertical kinetic energy provided by the take-off force, and these two parts of kinetic energy together determine the height of Duke's take-off jump.

Duke's jump was very hard, and after taking off, he stretched his body upwards and began to cross the pole, his body's center of gravity was obviously more than 2.30 meters, and all he had to do now was to stop all parts of his body from touching the pole at the moment of the electric flash.

After the head and shoulders crossed the pole first, Duke actively reversed his shoulders, raised his hips, tucked his abdomen, and tucked his legs, and the active stunts were all opened, and his pants were taken off, so he had to get a shot!

Doucle's pole passing technique is quite beautiful and can be called a textbook.

Even Wang Yu couldn't help but stand up and yelled for his rival Du Ke: "NICE! ”

Zhang Guowei was half surprised and half nervous, because he was under a lot of pressure to find that Du Ke successfully crossed the height of 2.30 meters in the second jump! (To be continued.) )
