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 Athletics Team, he was usually doing some administrative work and never used any special sports. The identity of the coach appears on the training ground.
"It seems that you really don't know. Director Ma used to be a long jump coach." Liu Feiren then explained: "Director Ma was a special era when he was 17 or 18 years old. At that time, the physical training team was not very good at all. Training, not to mention any special track and field, so Director Ma did not become a sports school coach for a few years. After the college entrance examination was resumed, Director Ma went to college and then graduate students, mainly in track and field teaching and training. 'S research, he became a coach on the national team after graduation, and he didn't coach athletes much about ten years ago."
Liu Feiren then added: "It is said that Director Ma has made great efforts in long jump training and has published several top-level papers. Now the training system for the long jump projects of various domestic training bureaus is basically proposed by Director Ma back then. Actually, I haven’t seen Director Ma coaching athletes, but some seniors said that Director Ma’s coaching level is very high and very strict. It is said that the Asian long jump record holder in our country was crying by Director Ma. ."
"I don't think Director Ma is so powerful. I thought he was born in administrative logistics. I didn't expect to be a coach." Zhang Guan had made up his mind. After returning, he went to Director Ma to talk about the practice of long jump.
...
"Do you want to practice long jumps?" The expression on Director Ma's face changed, and he continued: "Why? Are you tired of 400 meters? Or do you want to be the second Karl-Lewis?"
"Look what you said..." Zhang Guan smiled embarrassedly: "Isn't this trying to try my potential."
"Long jump is not as easy as you think. Not only body, but technology! Technology!" Director Ma specially emphasized the word "technology", obviously implying Zhang Guan's poor ability to learn technology.
"Technical aspects can be practiced slowly, or should you let me try to learn first?" Zhang Guan asked.
Director Ma was lost in contemplation. He was thinking about how to make Zhang Guan give up the years of long jump.
From the perspective of the long jump coach, Zhang Guan has enough physical talent. As long as he can master the technical essentials of the long jump, it is not impossible to rush into the long jump world championship in the future. Teaching a world champion is definitely the greatest achievement of a coaching 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 project. Now Zhang Guan’s 400-meter sprint has not yet been practiced, and he should not practice new events anymore. People’s energy is limited. Zhang Guan is already working on three sprints at the same time. If he joins the long jump, his energy will be increased Get involved. It is likely that the level of other projects affected has also declined.
Director Ma is not a very unreasonable person. He knows that Zhang Guan is a very opinionated person. If he refuses Zhang Guan directly now, it is definitely not a suitable choice. Director Ma hopes to be able to lead by initiative. Let Zhang Guan give up the idea of ​​practicing long jump.
"Long jump is not so easy to be practiced. Although a strong sprinter will practice long jump. The level is certainly not bad, but everything is not absolute. If you really want to try a long jump, it is not impossible. I can send you a coach who teaches long jump."
Before Zhang Guan was happy, Director Ma's voice changed, and then said: "But I can only give you ten days. The grand ceremony of the sports figures of the Central Power Group will be held just ten days later, so I will give you these ten. Days. Ten days. If you can prove that you are suitable for long jump, I will allow you to practice long jump, and I will personally make a training plan for you; but if you can’t prove yourself suitable for long jump in ten days, then Give me the idea of ​​practicing long jump and give me 400 meters, how do you feel?"
"Yes." Zhang Guan nodded and agreed, and then said: "But what is the standard that proves that I am suitable for long jump?"
"Look at the results. Ten days later, after the sports mission awards ceremony is over, I will give you a field test." Director Ma continued: "At that time, we will follow the standards of the competition and allow you to try six jumps, as long as you have Once you can meet the standards of national sports athletes, even if you meet the standards, how?
"No problem, that's it!" Zhang Guan said confidently.
Director Ma looked at Zhang Guan with a smile, and then said: "Don't talk big words, do you know how many meters the national sports athletes have in the long jump?"
"It certainly won't be too much. According to the standards of our national track and field events, it is difficult for international athletes to achieve the goal, but national athletes are generally easier." Zhang Guan said.
"You're talking about sprinting! Long jump is not like this." Director Ma looked like a scheming master and said: "The national athlete's achievement in the long jump is seven to eight meters!"
...
Although the strength of the national team's long jump is not strong in the world, it is definitely a first-class level in Asia. Among athletes’ technical grade standards, the international standard for long-jump events is 8 meters, the national standard for athletes is 7.80 meters, and the b-mark for the Olympic Games is 8.05 meters.
If you can jump 7.80 meters, it will definitely be eliminated at the Olympics, and it will definitely have a chance to impact the medals in the Asian games. Take the Doha Asian Games as an example, the long jump champion's score is 8.02 meters, the runner-up is 7.88 meters, the third runner-up is 7.85 meters, and the temple runners have reached 7.78 meters, which means that in the Asian Games this level of competition, only three athletes can skip 7.80 meters.
In ten days, from a rookie who can't even basic long jump skills, to become an athlete who can win medals in the Asian Games, anyone knows that this is an impossible task. Therefore, Director Ma felt that Zhang Guan was defeated!
...
The long jump consists of four parts: running, taking off, flying and landing.
Zhang Guan originally thought that for himself, running should be the least need to practice, but when he really started to learn long jump, Zhang Guan found that only a running, but it contains a lot of knowledge.
The purpose of running is to make your body reach the highest speed. The running distance of general male athletes is between 40 meters and 45 meters, and the pace during the running is 22 to 24 steps. When specific to each athlete, his approach distance will be more precise, and the pace of the approach will be a fixed number of steps. In actual competitions, athletes also need to adjust the distance of the run-up based on factors such as the softness of the runway, the coldness of the climate, whether it is downwind or upwind, and physical conditions.
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 the last few steps of the run, especially the last three-step run, which will directly affect the stepping on the springboard and after The jump situation is especially important for the entire run-up process. For a professional athlete, adjusting the last few runs is the most basic technique.
The run-up is followed by 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 boarding, but in terms of technology, there is a requirement for the landing angle when taking off; and in the buffering stage, there is also a maximum knee bending angle during the jumping of the athlete’s jumping leg. Required; as for the stage of stretching, the center of gravity of the body should be raised as much as possible. This not only has technical requirements for the lower limbs, but also technical requirements for the upper limbs.
After taking off, there is a vacating phase. There are three main postures in the air: "squatting", "standing up" and "walking". Squatting is the easiest and best posture; standing up is more difficult than squatting. The advantage is that it can better control the forward direction of the athlete's body in the air, but it is not conducive to getting a good landing posture; and Walking is more conducive to keeping the body balanced in the air, and has advantages in landing posture control.
Each of these three poses has its pros and cons. Although more and more people are using walking, it does not mean that other poses are not used by anyone. Even in the world's highest level of competition, athletes will still use squatting. In the form of flying, such as the 2008 Olympic Games long jump champion Saradino, he likes to use the simplest squat.
In the final landing, athletes are required to flex their knees and extend their calves quickly when landing. When touching the sand, they should move their bodies forward as much as possible, and then use their strength to stand up. In the landing, it is absolutely taboo to land on the part first or go to the ground with hands first, and we saw in the game that many athletes were sitting in the sand pool after landing, when in fact their hit the ground, The body has slid forward a great distance, and the place where their touches the ground is actually after the foot hits.
...
The running approach is not difficult for Zhang Guan. It is nothing more than maximizing the speed as much as possible. This is the part Zhang Zhang is best at.
For the average beginner, the first difficulty in long jump is to turn running into jump. The faster the run-up speed of the long jump event, the farther the jump, but beginners do not know how to convert the kinetic energy of running into the kinetic energy of jumping, so when they do long jump, they seem to run fast, but in fact " "Run" and "jump" are separate, and the two actions are combined.
On this point, Zhang Guan did a good job. After sprinting and jumping to the master level, Zhang Guan could convert the kinetic energy of the run-up into the kinetic energy of the take-off.
However, the subsequent vacated part made Zhang Guan feel the difficulty. (To be continued.)
