Chapter 155 The King of Track and Field Ten Days to Prove Yourself

Zhang Guan turned his head and looked at Director Ma who was sitting obliquely in front of him. In Zhang Guan's impression, although Director Ma was the head coach of the national track and field team, he was usually doing some administrative work, and never used any special sports The identity of the coach appears on the training field.

"It seems that you really don't know. Director Ma used to be the long jump coach." Liu Feiren continued to explain: "When Director Ma was seventeen or eighteen years old, it happened to be a special era, and the sports team at that time was not very good at all. Training, let alone track and field specialization, so Director Ma changed his career as a sports school coach after a few years of being an athlete. Later, the college entrance examination resumed. Director Ma took the university entrance examination, and then took the postgraduate entrance examination, mainly for track and field teaching and training. After graduating, he worked as a coach in the national team and stopped coaching athletes about ten years ago."

Liu Feiren then added: "It is said that Director Ma has put a lot of effort into long jump training and has published several top-level papers. The training system for long jump events in various training bureaus in China is basically proposed by Director Ma back then. Yes. In fact, I have never seen Director Ma coaching athletes, but I heard from some seniors that Director Ma’s coaching level is very high and he is very strict. It is said that the Asian long jump record holder in our country cried when he was trained by Director Ma. .”

"I didn't expect Director Ma to be so powerful. I thought he was from administrative logistics, but I didn't expect that he was also a coach." Zhang Guan had already made up his mind to talk to Director Ma about practicing long jump after returning home.

...

"Do you want to practice long jump?" The expression on Director Ma's face fluctuated, and he continued: "What? Are you tired of playing 400 meters again? Or do you want to be the second Carl Lewis?"

"Look at what you said..." Zhang Guan smiled awkwardly: "Isn't this trying to test my potential?"

"Long jump is not as easy as you think. It requires not only the body, but also technology! Technology!" Director Ma specially emphasized the word "technology", obviously implying that Zhang Guan's ability to learn technology is very poor.

"Technology can be practiced slowly, why don't you let me learn it first?" Zhang Guan asked.

Director Ma fell into deep thought. He was thinking about how to get Zhang Guan to give up his years of long jump practice.

From the perspective of a long jump coach, Zhang Guan has enough physical talent. As long as he can master the technical essentials of long jump, it is not impossible to become the world champion in long jump in the future. Teaching a world champion is definitely the greatest achievement in a coach's career.

However, from the perspective of the head coach of the national team, Director Ma does not want Zhang Guan to enter the long jump event. Now that Zhang Guan has not practiced the 400-meter sprint well, he should not practice new events. Human energy is limited. Zhang Guan is currently doing three sprint events at the same time. If he adds the long jump, his energy will be reduced. The level at which other projects are implicated and likely to be affected has also declined.

Director Ma is not the kind of unreasonable person. He knows that Zhang Guan is a very assertive person. If he directly rejects Zhang Guan now, it is definitely not a suitable choice. Director Ma hopes to be able to actively guide him. Let Zhang Guan give up the idea of ​​​​practicing long jump.

"Long jump is not so easy to practice. Although a good sprinter can practice long jump, the level will definitely not be bad, but everything is not absolute. If you really want to try long jump, it is not impossible. I can send you a long jump coach."

Before Zhang Guan was happy, Director Ma's voice changed, and he continued: "But I can only give you ten days, and CCTV's sports figure award ceremony will be held in ten days, so I will give you ten days. Days. In ten days, if you can prove that you are suitable for practicing long jump, I will allow you to practice long jump, and I will personally make a training plan for you; but if you cannot prove that you are suitable for practicing long jump in ten days, then Give me up on the idea of ​​practicing long jump and practice 400 meters for me, what do you think?"

"Yes." Zhang Guan nodded and agreed, and then continued: "But what is the standard to prove that I am suitable for practicing long jump?"

"Look at the results. Ten days later, after the end of the award ceremony for the sports mission, I will give you a field test." Director Ma continued: "At that time, we will follow the competition standards and allow you to try jumping six times. If you can reach the standard of a national-level athlete at one time, even if you meet the standard, how about it?"

"No problem, it's settled!" Zhang Guan said confidently.

Director Ma looked at Zhang Guan with a smile, and then said: "Don't talk big, do you know how many meters the standard for a national athlete in the long jump event is?"

"It's definitely not too much. According to the standards of our national track and field events, it is very difficult for international athletes and athletes to reach the standard, but it is generally easier for national athletes." Zhang Guan said.

"You're talking about sprinting, right? That's not how long jumping is." Director Ma said as if he had succeeded in a trick, "The national-level athletes in the long jump event meet the standard of 7.8 meters!"

...

Although the strength of the national team's long jump is not strong in the world, it is definitely top-notch in Asia. In terms of athletes' technical level standards, the standard for international athletes in the long jump event is 8 meters, the standard for national athletes is 7.80 meters, and the B standard for the Olympic Games is 8.05 meters.

If you can jump 7.80 meters, it will definitely be eliminated in the qualifying competition in the Olympic Games, and you will definitely have a chance to hit the medal in the Asian competition. Taking the results of the Doha Asian Games as an example, the result of the long jump champion is 8.02 meters, the runner-up is 7.88 meters, the third place is 7.85 meters, and the fourth place has reached 7.78 meters. That is to say, only three athletes can jump 7.80 meters in a competition of this level in the Asian Games.

In ten days, from a rookie who doesn't even know basic long jump skills to an athlete who can win medals in the Asian Games, everyone knows that this is an impossible task. So Director Ma felt that Zhang Guan was doomed!

...

The long jump consists of four parts: run-up, take-off, airborne and landing.

Zhang Guan originally thought that for him, the run-up should be the least practiced, but when he really started to learn the long jump, Zhang Guan discovered that there is a lot of knowledge in just a run-up.

The purpose of the run-up is to let your body reach the highest speed. Generally, the run-up distance of male athletes is between 40 meters and 45 meters, and the pace during the run-up is 22 to 24 steps. When it comes to each athlete, his approach distance will be more accurate, and his approach pace will be a fixed number of steps. In actual competition, athletes also need to adjust the approach distance according to factors such as the softness of the runway, the coldness of the climate, whether it is downwind or headwind, and physical condition.

At the same time, there are also related technical requirements for the starting posture of the run-up, the acceleration method of the run-up, etc., the most critical of which is that in the last few steps of the run-up, especially the last three steps of the run-up, it will directly affect the stepping on the springboard. The jumping situation is particularly important for the entire run-up process. For a professional athlete, adjusting the approach of the last few steps is the most basic technique.

After the run-up is the take-off, which is divided into three parts: upper board, cushioning and stretching. Each part has different mechanical characteristics and specific requirements.

It is the most basic requirement not to step on the marking line when getting on the board. In terms of technology, there are requirements for the landing angle when taking off; Requirements; as for the stretching stage, the center of gravity of the body should be raised as much as possible, which not only has technical requirements for the lower limbs, but also for the upper limbs.

After the take-off is the vacating stage. There are three main postures in the air: "squatting", "standing up" and "walking". The squatting pose is the easiest and best posture to master; the standing pose is much more difficult than the squatting pose. The advantage is that it can better control the forward rotation direction of the athlete's body in the air, but it is not conducive to obtaining a good landing posture; and The walking style is more conducive to maintaining the balance of the body in the air, and it also has advantages in controlling the landing posture.

These three postures have their own advantages and disadvantages. Although more and more people are beginning to use the walking posture, it does not mean that no one uses other postures. Even in the highest level of competition in the world, some athletes still use squatting For example, Saladino, the 2008 Olympic long jump champion, likes to use the simplest squatting style.

In the final landing, the athletes are required to quickly bend their knees and stretch their calves forward when they land on the ground. When they touch the sand surface, they should move their bodies forward as much as possible, and then stand up with their strength. In the landing, it is absolutely taboo to land on the buttocks first or use the hands to support the ground first. In the competition, we saw many athletes sitting in the sand pool after landing. In fact, when their buttocks hit the ground, The body has slid so far forward that the point where their butt meets the ground is actually behind the point where the foot strikes.

...

The run-up is not difficult for Zhang Guan. It is nothing more than maximizing the speed as much as possible. This is the part Zhang Guan is best at.

For general beginners, the first difficulty in long jump is to turn running into jumping. The faster the run-up speed in the long jump event, the farther the jump, but beginners don't know how to convert the kinetic energy of running into the kinetic energy of jumping, so when they perform long jump, it seems that the run-up speed is very fast, but in fact " "Run" and "jump" are separate, and the two actions are combined.

Zhang Guan has done a good job on this point. After the skill of sprint jump reaches the master level, Zhang Guan can better convert the kinetic energy of the run-up into the kinetic energy of the take-off.

However, Zhang Guan felt the difficulty in the vacating part afterwards.
