Zhang Guan turned to look at Director Ma, who was sitting diagonally in front of him. In Zhang Guan's impression, although Director Ma was the head coach of the national track and field team, he usually did some administrative work and never specialized in any specific sports. The identity of the coach appears on the training ground.
"It seems you really don't know. Director Ma was a long jump coach before." Liu Feiren continued to explain: "Director Ma happened to be in a special era when he was 17 or 18 years old. The sports team at that time was not very good at all. Training, let alone track and field specialties, so Director Ma changed his profession to become a sports school coach after only a few years of being an athlete. Later, the college entrance examination resumed, Director Ma took the college entrance examination, and then the postgraduate entrance examination, mainly engaged in track and field teaching and training. After graduation, I became a coach for the national team, but I 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 published several top-level papers. The training systems for long jump events in various domestic training bureaus are basically proposed by Director Ma back then. In fact, I have never seen Director Ma coach athletes, but I heard from some seniors that Director Ma has a very high level of coaching and is very strict. It is said that the Asian long jump record holder in our country was made to cry by Director Ma. .”
"I didn't expect Director Ma to be so good. I thought he had a background in administrative logistics, but I didn't expect him to be a coach as well." Zhang Guan had already made up his mind to talk to Director Ma about practicing long jump after he returned.
…
"Do you want to practice long jump?" The expression on Director Ma's face changed, and he continued: "What? Are you tired of the 400 meters again? Or do you want to be the second Carl Lewis?"
"Look what you said..." Zhang Guan smiled awkwardly: "Aren't you just trying to test your 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 poor.
"Techniques can be practiced slowly. Why don't you let me try it out first?" Zhang Guan asked.
Director Ma fell into deep thought. He was thinking about how to make Zhang Guan give up his 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 a world champion in long jump in the future. Coaching a world champion is definitely the greatest achievement in a coaching career.
However, from the perspective of the national team head coach, 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. People's energy is limited. Zhang Guan is already doing three sprint events at the same time. If he adds the long jump, his energy will be reduced. Being involved, it is likely to affect the level of other projects.
Director Ma is not the kind of unreasonable person. He knows that Zhang Guan is a very independent person. If he directly rejects Zhang Guan now, it is definitely not a suitable choice. Director Ma hopes to actively guide him. Let Zhang Guan give up the idea of practicing long jump.
"Long jump is not that easy to practice well. Although if a strong sprinter practices long jump, his 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 could be happy, Director Ma changed his tone and continued: "But I can only give you ten days. CCTV's Sports Figure Awards Ceremony will be held in ten days, so I will give you these 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 within ten days, you cannot prove that you are suitable for practicing long jump, then Give me the idea of practicing the long jump and practice the 400 meters properly, what do you think?"
"Okay." Zhang Guan nodded in agreement, and then continued: "But what are the criteria to prove that I am suitable for practicing long jump?"
"Look at the results. Ten days later, after the Sports Awards Ceremony, we 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. As long as you have How about if you can reach the standard of a national-level athlete for once, even if you reach the standard?"
"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 are the standard for national-level athletes in the long jump event?"
"Definitely not too many. According to the standards of our national track and field events, it is difficult for international athletes to meet the standards, but it is generally easier for national athletes." Zhang Guan said.
"You are talking about sprinting! The long jump is not like this." Director Ma said as if his scheming had succeeded: "The standard score for national athletes in the long jump event is 7.8 meters!"
…
Although the national team's long jump strength is not strong in the world, it is definitely considered top-notch in Asia. Among the athletes' technical level standards, the international athlete standard for long jump is 8 meters, the national athlete standard is 7.80 meters, and the Olympic B standard is 8.05 meters.
If you can jump 7.80 meters, you will definitely be eliminated in the qualifying rounds in the Olympic Games, and you will definitely have a chance to win medals in Asian competitions. Taking the results of the Doha Asian Games as an example, the long jump champion’s results are 8.02 meters, the second place is 7.88 meters, the third place is 7.85 meters, and the second place has reached 7.78 meters, which means that in a competition of this level in the Asian Games, only three athletes can jump 7.80 meters.
In ten days, from a rookie with no basic long jump skills to an athlete capable of winning medals in the Asian Games, everyone knows that this is an impossible task. Therefore, Director Ma felt that Zhang Guan was destined to lose!
…
The long jump consists of four parts: run-up, take-off, airborne and landing.
Zhang Guan originally thought that for him, the approach run was the one that required the least amount of practice. However, when he actually started learning long jump, Zhang Guan discovered that just one approach run contained a lot of knowledge.
The purpose of the approach is to allow your body to reach the highest speed. Generally, the approach distance of male athletes is between 40 meters and 45 meters, and the pace during the approach is 22 to 24 steps. When it comes to each athlete, his approach distance will be more accurate, and the approach pace will also be a fixed number of steps. In the actual competition, athletes also need to adjust the distance of the approach based on factors such as the softness of the track, the coldness of the climate, whether it is a tailwind or a headwind, and their physical condition.
At the same time, there are also relevant technical requirements for the starting posture of the approach, the acceleration method of the approach, etc. The most critical one is the last few steps of the approach, especially the last three steps, which will directly affect the steps on the springboard and the subsequent steps. The jumping situation is particularly important to the entire approach process. For a professional athlete, adjusting the last few steps of the approach is the most basic technique.
After the run-up is the take-off, which is divided into three parts: upper board, buffer and extension. Each part has different mechanical characteristics and specific requirements.
When getting on the board, you cannot step on the marking line. This is the most basic requirement. In terms of technology, there are requirements for the landing angle when taking off; and in the buffer stage, there are also requirements for the maximum knee bend angle of the athlete's take-off leg during the jump. requirements; as for the extension and kicking stage, the center of gravity of the body must be raised as much as possible. This not only has technical requirements for the lower limbs, but also has technical requirements for the upper limbs.
After taking off, there is the airborne stage. There are three main postures in the air: "crouching posture", "standing posture" and "walking posture". The squatting posture is the simplest and easiest to master; the push-up posture is much more difficult than the squatting posture. 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 balance in the air, and is also more advantageous in controlling 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 competitions in the world, there are still athletes who use the squatting posture. For example, Saladino, the 2008 Olympic long jump champion, likes to use the simplest squatting posture.
In terms of the final landing, athletes are required to quickly bend their knees and extend their calves forward when landing. When touching the sand, they should move their bodies forward as much as possible, and then use their strength to stand up forward. When landing, it is absolutely taboo to land with your butt first or use your hands to support the ground first. In competitions, we see many athletes sitting in the sand pool after landing. In fact, when their butt touches the ground, The body has slid forward a large distance, and the point where their butt touches the ground is actually after the foot touches down.
…
The run-up is not difficult for Zhang Guan. It is nothing more than maximizing the speed as much as possible. This is what Zhang Guan is best at.
For the average beginner, the first difficulty in long jump is to turn running into jumping. The faster the approach speed in the long jump event, the further they jump, but beginners do not know how to convert the kinetic energy of running into the kinetic energy of jumping, so when they perform the long jump, it seems that the approach speed is quite fast, but in fact " "Running" and "jumping" are separate, and the two actions are not combined.
Zhang Guan is very good at this point. After reaching the master level in the sprint and jump skill, Zhang Guan can better convert the kinetic energy of the approach into the kinetic energy of the take-off.
But the subsequent flying part made Zhang Guan feel the difficulty.
