In the process of taking off the long jump, the center of gravity of the athlete's body moves according to the parabolic trajectory, and the purpose of the action in the process of taking off is mainly to maintain the balance of the body and complete the effective landing, so as to make better use of the parabolic trajectory and strive to achieve better results.

All movements after taking off must be carried out after the "air step", but beginners in the long jump do not remember to do the movements at all when the body is in the air, perhaps because the body's reaction cannot keep up, and the body has already landed when the body wants to make the move.

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

The aerial action in the long jump is still a very big test of the strength of the waist and abdomen, and the most likely place for long jumpers to be injured is not the legs, but the waist. However, after all, Zhang Guan has strengthened the skill of "body coordination", and after a long time of practice, Zhang Guan finally mastered the technical movements of squatting. However, it is only a mastery, and there is still a huge gap between the perfection of technical movements.

In the next landing training, the first thing to overcome is the psychological factor. For people who don't know how to do long jump, the most worrying thing about landing is falling, which is a natural fear of losing balance in human beings, so people who do long jump for the first time often nail their feet directly into the sand pool when they land, or take several steps forward to maintain their body balance. Professional athletes, on the other hand, use the momentum to get up from the sand pit.

Whether it is a high jumper or a long jumper, they are not afraid of falling, they have overcome the fear of falling through long-term practice, and ordinary people, even if they keep telling themselves in their hearts that the body will not be injured if they fall in the sand pool, but when they really want to fall, the body will involuntarily make extra movements to protect themselves.

Although Zhang Guan has a strong system in his body. But to overcome the psychological factor, the system can't help him, he can only get up from the fall again and again, and adapt to the feeling of falling in the sand again and again, until he is no longer afraid of falling.

On March 25, the Sports Personality of the Year Award Ceremony was held in Beijing.

This year's Man of the Year selection kicked off at the end of last year, and there were hundreds of candidates at the beginning, including not only athletes, but also coaches, sports teams, sports commentators, owners of sports sponsorship brands, club owners and so on. And the athletes on the shortlist, in addition to Chinese athletes. There are also foreign athletes such as Becky, Tiger Woods, Federer, Alonso, Isinbayeva and even Sharapova on the initial shortlist.

Of course, it is impossible for these foreign big-name athletes to attend this award ceremony, and they are naturally not among the final winners. In fact, the winners of this year's sports task have basically been decided, and Zhang Guan and Liu Feiren will definitely occupy a place each.

It is worth mentioning that the organizers invited former IOC President Samaranch to present the awards, and many domestic entertainment stars attended, which was a highlight of the awards ceremony.

Offstage. Zhang Guan and Liu Feiren sat together, each holding a trophy in the shape of a small gold in their hands.

"Why haven't you returned to the Xinzhuang base in the past few days, I haven't seen you in the base, what are you busy with? Business again?" Liu Feiren asked.

Zhang Guan shook his head. whispered: "I'm in the training center of the national sports body, secretly practicing the long jump." ”

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

"I didn't agree. Director Ma asked me to practice first. Zhang Guan told Liu Feiren about jumping to 7.8 meters in ten days.

"Jumping to 7.8 meters in 10 days? How is this possible! You're crazy! I see that your kid was sold and helped to count the money! Liu Feiren couldn't stop shaking his head.

"I have to try it anyway! Besides, don't I often work miracles? Zhang Guan looked confident.

"It's different, it was a sprint before. Running, especially the 100-meter sprint. It mainly depends on talent, and the technical requirements are much lower than those of other track and field events. People are born to run, but the long jump requires skills, and without three or five months of hard work, it is difficult to master even the most basic skills. Liu Feiren said.

"Well, I'm just learning how to take off and land now." Zhang Guan continued: "But tomorrow is going to be tested, after ten days of hard work, it depends on tomorrow's trembling, you have to try it!" By the way, will you go back tomorrow? If you don't, come and see how I jump over 7.8 meters! ”

"I don't have time to go crazy with you, I have to go back early tomorrow morning, I just got a foot injury, I need to get back as soon as possible. Time is running out, it's the end of March, and there's still more than a month to go, and there will be a race until the beginning of May. Liu Feiren said.

Zhang Guan thought for a while and asked, "Is it the Japanese Grand Prix of the Athletics Federation?" The one in Osaka? ”

"Yes, we all participated last year, and you had a match with Gatling." Liu Feiren continued: "In addition, in July, I am going to go to Europe to participate in the Golden League in Paris and the Super Grand Prix in Lausanne. ”

Zhang Guan was slightly stunned: "There is no 110-meter hurdles event in the Golden League this year, right?" ”

"Don't forget that the host location can add projects on an ad hoc basis. This year's Golden League Paris will add a 110-meter hurdles event, and France's Doucoure, this 110-meter hurdles is specially designed for him! I'm kind of bare, too. Go earn some IAAF points. Liu Feiren said with a smile.

……

The day after the Sports Personality of the Year Award Ceremony, Zhang Guan ushered in his first long jump test.

"How is it possible to jump from nothing to 7.8 meters in 10 days! Zhang Guan, this kid is also real, he actually promised you, I think you deliberately fooled the stupid boy! Director Yu said.

Director Ma smiled: "Now that I think about it, I seem to be a little too cruel, and I should have set him a little lower, such as 7.3 meters for first-class athletes, which also gave him hope." But then again. If you don't be ruthless, you can't do it, Zhang Guan, this kid is still young, and the road ahead is still very long, it's just that he's young and ignorant, let's not mess around with him. Let's let him practice sprinting first, as for the long jump, if he really has this talent, when his sprinting skills are stable, maybe he will try it. ”

"Hmph...... I don't think you should talk too much. Director Yu continued: "Look at Zhang Guan, he looks full of confidence. Maybe he can really jump 7.8 meters! Don't forget, but there are six chances, and you'll be dumbfounded. ”

"Impossible, absolutely impossible!" Director Ma shook his head violently: "7.8 meters!" Not to mention giving him six chances, even if he is given sixty chances, he can't jump over. ”

As soon as Director Ma's voice fell, Zhang Guan had already started his first run.

"The pace of the run is very good, the speed is so fast." Yu Dao opened his mouth and commented.

Director Ma nodded very approvingly, Zhang Guan's performance in the run-up process was also expected. After all, Zhang Guan is the world record holder in the men's 100 meters, so in terms of running speed alone, no one in the world can be faster than Zhang Guan.

But the long jump is not a sprint, no matter how fast it is. You also need to turn the speed of the run-up into the power of jumping.

Zhang Guan's speed had been increased to the extreme, and then he stepped on the pedal and jumped forward violently.

"It's great to get in the air!" Director Ma gasped, under normal circumstances. The higher the height in the air, the farther the jump, and Zhang Guan showed the height of the air in this jump. It has already exceeded the average of national team long jumpers.

Zhang Guan used a squatting posture in the air, only to see Zhang Guan in the air trying to maintain the posture of jumping, and then the jumping legs stretched forward happily, and the legs were lifted and stretched in front of the body, ready to land.

"This action is not good, I didn't grasp the time, I did it too early, and it will definitely affect the balance of the landing." Director Ma instantly gave an evaluation in his heart.

"It's landed." Zhang Guan fell into the sand pool, and his feet drew a mark of different colors in the sand pool.

"This seems to be too much!" Director Yu suddenly said, from his point of view, the place where Zhang Guan finally landed should be 7.8 meters.

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

"Foul on the line, defeat!" The coach in charge of the referee spoke.

Director Ma let out a sigh of relief, the one just now, Zhang Guan should have been pressed on the 7.8-meter line, but fortunately, he failed to step on the line.

"It's so hanging! It almost passed. Director Ma said.

"What a pity! It's almost over! Yu said at the same time.

Director Ma glared at the guide: "Old Yu, what do you mean, do you still hope that he can really jump 7.8 meters!" Don't forget that you are the coach in charge of sprinting, is it possible that you are really willing to send Zhang Guan out to practice long jump? ”

Director Yu smiled awkwardly, at this time he was really a little conflicted in his heart, as the coach in charge of sprinting, of course he didn't want Zhang Guan to practice the long jump, but he hoped that his disciples could achieve good results, even in other track and field events.

After a minute's break, Zhang Guan began his second attempt.

Running, jumping, taking off, and landing, Zhang Guan's movements were still not perfect, but this time it was a success, and the referee raised the white flag of successful jumping.

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

"I've crossed the 7.3m national first-class athlete line." Director Ma's face looked cloudy, and he muttered to the guide: "Fortunately, I didn't agree with him at that time to 7.3 meters, otherwise he would have really passed." ”

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

Director Ma took a deep breath: "Old Yu, what kind of monster do you say Zhang Guan, this kid has only been practicing for ten days!" It's only been ten days, and I jumped 7.3 meters! (To be continued.) )
