Long jump test

During the long jump, the athlete's body center of gravity moves according to the parabolic trajectory. The action during the flight is mainly to maintain the balance of the body and complete the effective landing, to make better use of the parabolic trajectory and strive to achieve better results.

All movements after taking off must be performed after the "flying step". However, the beginners of the long jump don't remember to do the action when the body is taking off, maybe the body's reaction can't keep up, and they have already landed.

Zhang Guan's aerial movements are the simplest "squatting", but he was not used to doing movements in the air when he first practiced. Zhang Guan felt that the most troublesome thing was not that his legs could not keep up, but the coordination of movement and waist and abdomen strength were too difficult to master.

The flying action in the long jump is still a great test of the strength of the waist and abdomen. The most vulnerable place for long jumpers is not the legs, but the waist. However, Zhang Guan has the skill enhancement of "body coordination" after all. After a long period of practice, Zhang Guan finally mastered the squatting technique. But it is only a matter of mastery, and there is still a huge distance from the perfect technical action.

The next landing training, the first thing to do was overcome the psychological factor. For those who do not know the long jump technique, the biggest worry about landing is falling. This is a natural fear of losing balance. So for the first time, people who jump for the first time often land on the sand with their feet, in the pool, or step forward a few steps to maintain the balance of the body. The professional athletes use the momentum to get up from the sand pool.

Whether they are high jumpers or long jumpers, they are not afraid of falling. They have overcome the fear of falling through long-term practice. For ordinary people, even if they keep telling themselves in the heart, they will not hurt their bodies in the sand pool, but when they fall, their body will involuntarily make redundant movements to protect themselves.

Although Zhang Guan has a powerful system in his body, he cannot help him by overcoming psychological factors. He can only climb up and down, again and again, to adapt to the feeling of falling in the sand. Until he is no longer afraid of falling.

On March 25th, the awards ceremony for sports figures was held in Beijing.

This year's Feng Yun Characters selection started at the end of last year. In the beginning, there were hundreds of candidates, not only athletes but also coaches, sports teams, sports commentators, sports sponsorship brand owners, club owners, and so on. In addition to the Chinese athletes, there are some foreign athletes on the shortlist, such as Beckham, Tiger Woods, Federer, Alonso, Isinbayeva, and even Sharapova is in the original candidate list.

Of course, these foreign big-name athletes can't attend this awards ceremony, and naturally, the final winners are not them. The winners of this year's sports mission selection have been laid down. Zhang Guan and Liu Feiren will certainly each occupy a place.

It is worth mentioning that the organizer invited the former President of the International Olympic Committee Samaranch to present the award. Also, there are many stars in the domestic performing arts industry, which is a highlight of the award ceremony.

Under the stage, Zhang Guan and Liu Feiren sat together, each holding a small gold-shaped trophy in their hands.

"Why haven't you returned to the Xinzhuang base in the past few days? I haven't seen you at the base. What are you busy with? Are you taking business activities again?" Liu Feiren asked.

Zhang Guan shook his head and whispered, "I'm secretly practicing long jump at the National Sports Training Center."

"Long jump!" Liu Feiren was taken aback, "When you came back from Moscow a few days ago, you told me about the long jump on the plane. I thought you were talking about joking. I didn't expect you to take it seriously. The team didn't stop you? Director Ma agreed?"

"He didn't agree. Director Ma asked me to practice first." Zhang Guan told Liu Feiren that he had jumped to 7.8 meters in ten days.

"Jump to 7.8 meters in ten days? How could this be done! Are you crazy? I think your kid was sold to help the number of people!" Liu Feiren shook his head.

"It's always a good try! Besides, don't I often create miracles." Zhang Guan seemed confident.

"Different, before that it was sprinting. Running, especially the 100-meter sprint event mainly depends on talent. The technical requirements are much lower than other track and field events. People are born to run, but a long-jump is an event where you need techniques, without three or five months of hard work, even the most basic techniques are difficult to master proficiency." Liu Feiren said.

"Well, I have just learned to vacate and land now." Zhang Guan continued, "But it will be tested tomorrow, and I have worked hard for ten days, just to see the results of tomorrow, I must try it! By the way, will you go back tomorrow? If you don't, you should come and see how I skipped 7.8 meters!"

"I don't have time to go crazy with you. I have to go back tomorrow morning. My foot injury is still there and I have to recover as soon as possible. Time is running out. It is now at the end of March and there is less than a month left. There will be a game by early May." Liu Feiren said.

Zhang Guan thought about it and asked, "Is it the IAAF Japan Grand Prix? The one in Osaka?"

"Yes, we all participated last year, and you also played a game with Gatlin." Liu Feiren continued, "In July, I plan to go to Europe to participate in the Gold League Paris event and the Super Grand Prix Lausanne Station."

Zhang Guan was slightly surprised, "There is a 110-meter hurdle in the Golden League this year?"

"Don't forget that the host site can temporarily add projects. This year's Golden League Paris station will add a 110-meter hurdle. For that French guy, this 110-meter hurdle is specially designed for him! I'm also covered to earn some IAAF points." Liu Feiren said with a smile.

...

The day after the sports figure awards ceremony, Zhang Guan ushered in his first long jump test.

"Within ten days, he can't jump into 7.8 meters. How could this be possible! That Zhang Guan child is indeed foolish, he even agreed to you, I think you deliberately fooled the silly boy!" Yu Gui said.

Director Ma smiled, "Now when I think of it, I seem to be a bit cruel. At first, I thought I should set the goal a bit lower for him, such as the 7.3m of a first-class athlete, to give him hope. But after all, it's not that cruel, Zhang Guan's child is still young, and his future is still very long. He's young and ignorant. We can't just follow him. Let him practice sprinting first. As for long jump, if he has a talent for this when his sprinting technology has stabilized, maybe we will let him try."

"Humph ... I don't think you should be too full of words." Yu Gui continued, "Look at Zhang Guan, with a confident look, maybe he can jump 7.8 meters! Don't forget, there are six chances, and you will be dumbfounded."

"Impossible, absolutely impossible!" Director Ma shook his head violently. "7.8 meters! Don't say give him six opportunities, just give him sixty opportunities, and he still won't be able to jump over."

Director Ma's words just fell, and Zhang Guan had already started his first run-up.

"The rhythm of the run-up is very good, and the speed is very fast." Yu Gui said.

Director Ma nodded in agreement, Zhang Guan performed well during the run-up process, and it was also within the expectations of Director Ma. Zhang Guan is after all the men's 100m world record holders, so if we only discuss the running speed, in the world someone can't be faster than Zhang Guan.

However, long jump is not a sprint. Even if the run-up is fast, you need to turn the speed of the run-up into the power of jumping.

Zhang Guan's speed has been improved to the extreme, and he then saw him stepping on the pedal and jumped forward violently.

"The flying height is great!" Director Ma took a breath. In general, the higher the flying height, the further the jump. Zhang Guan's flying height in this jump has exceeded the national team's long jumper average level.

Zhang Guan used the squatting vacant posture. He saw Zhang Guan struggling to maintain the take-off posture, and then the take-off legs stretched forward happily, and the legs were straightened up in front of the body, ready to land.

"This action doesn't work, he didn't grasp the time. If he did it too early, it affected the sense of balance on the floor." Director Ma gave an instant assessment in his heart.

"Failed." Zhang Guan fell into the sand pool, his feet drawn a trace of different colors in the sand pool.

"It seems to be over!" Yu Gui said suddenly. From his point of view, the place where Zhang Guan finally landed should be around 7.8 meters.

Director Ma's heart suddenly hung, and then he saw that the referee at the springboard had already raised the red flag.

"Foul on the line, failure!" The coach in charge of the referee said.

Director Ma took a deep breath. The previous one, Zhang Guan should be pressed against the line of 7.8 meters, but fortunately, he failed to step on the line.

"It's hanging! Almost passed." Director Ma said.

"It's a pity! Almost passed!" Yu Gui said at the same time.

Director Ma glared at the coach, "Old Yu, what do you mean, you still hope he can jump 7.8 meters! Don't forget that you are the coach in charge of sprinting, are you willing to share Zhang Guan, and allow him to practice long jump?"

Yu Gui smiled embarrassingly. At this time, he was a bit contradictory. As the coach in charge of sprinting, he certainly did not want Zhang Guan to practice long jump, but he also hoped that his disciples could achieve good results, even in other track and field events.

After a minute of rest, Zhang Guan began his second test jump.

Running, taking off, flying, landing, Zhang Guan's actions are still not perfect, but this time it was successful anyway, the referee raised the white flag of successful jumping.

"7.32 meters!" The surveyor shouted Zhang Guan's achievement.

"It's past the 7.3 m national first-class athlete line." Director Ma's complexion appeared murky, he muttered to the coach, "Fortunately, he did not agree with him at 7.3 m, otherwise he might have passed."

"Don't worry, there are still four jumps left!" Yu Gui turned and said.

Director Ma took a deep breath, "Old Yu, What kind of monster is this Zhang Guan, it took only ten days to practice! Only ten days, he skipped 7.3 meters!"
