Zhang Guan turned his head to look at Director Ma who was sitting 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 he had never appeared on the training ground as a special sports coach.

"It seems that you really don't know, Director Ma was the coach of the long jump before." Liu Feiren then explained: "Director Ma was seventeen or eighteen years old when it was a special era, at that time the sports team did not train much at all, let alone any track and field special, so Director Ma did not be an athlete for a few years before he changed careers to become a sports school coach, and later the college entrance examination resumed, Director Ma was admitted to the university, and then took the postgraduate examination, mainly for the study of track and field teaching and training, and after graduation, he became a coach in the national team, and he did not coach athletes much about ten years ago." ”

Liu Feiren then added: "It is said that Director Ma has put a lot of effort into the research of long jump training, and has also published several top papers. In fact, I have never seen Director Ma coach athletes, but I heard some seniors say that Director Ma's coaching level is very high and very strict, and it is said that the Asian long jump record holder in our country was trained by Director Ma and cried. ”

"I didn't expect Director Ma to be so powerful. I thought he was from the administrative and logistics side, but I didn't expect him to be a coach as well. Zhang Guan has already made up his mind, and when he goes back, he will go to Director Ma to talk about practicing the long jump.

……

"You want to practice the long jump?" The expression on Director Ma's face changed, and he continued, "What? Is it 400 meters and tired of playing? Or do you want to do a second Carl Lewis? ”

"Look at what you're talking about......" Zhang Guan smiled awkwardly: "Isn't this trying to test your potential?" ”

"The long jump is not as easy as you think, it requires not only the body, but also the technique! Technology! Director Ma specially emphasized the word "technology", which obviously implied that Zhang Guan's ability to learn technology was very poor.

"You can practice the technique 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 practicing long jump.

From the perspective of the long jump coach, Zhang Guan has enough physical talent. As long as you can master the technical essentials of the long jump, it is not impossible to rush to the long jump world championship in the future. Coaching 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 did not want Zhang Guan to enter the long jump project. Now Zhang Guan's 400-meter sprint has not been practiced, it should not be practiced in new events, people's energy is limited, Zhang Guan is now doing three sprinting events at the same time, if you add the long jump, the energy will be involved. There has also been a decline in the level that is likely to affect other projects.

Director Ma is not the kind of person who is very unreasonable, 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 take the initiative to guide Zhang Guan to give up the idea of practicing long jump.

"The long jump is not so easy to practice, although the level of a good sprinter will definitely not be bad if he goes to practice the long jump, but everything is not absolute. If you really want to try your hand at the long jump. It's not impossible, I can send you a coach to teach long jump. ”

Before Zhang Guan could be happy, Director Ma's voice changed, and then said, "But I can only give you ten days." The sports figure of the year award ceremony will be held in ten days, so I will give you these ten days. Ten days, if you can prove that you are fit to practice the long jump, I will allow you to practice the long jump. I'll do the training plan for you personally; But if you can't prove that you're fit for the long jump in 10 days, then discourage me from practicing the long jump. Give me a good 400-meter practice, what do you think? ”

"Yes." Zhang Guan nodded in agreement, and then continued: "But what is the standard that proves that I am suitable for practicing 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 to jump six times, as long as you can meet the standards of national athletes once, even if you meet the standards, how about it?" ”

"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, do you know how many meters the standard of national athletes in the long jump event is?" ”

"There will definitely not be too many, according to the standards of our national track and field events, international athletes, it is difficult for athletes to reach the standard, but it is generally easier for national-level athletes." Zhang Guan said.

"You're talking about sprinting! That's not what the long jump looks like. Director Ma looked like he had succeeded in his trick and said: "The national athlete in the long jump event has reached the standard score of seven meters and 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 the technical standards for athletes, the international standard for athletes in the long jump 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 at the level of qualifying for the Olympic Games, and it will definitely have a chance to impact the medal results in the Asian Games, 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 third place has reached 7.78 meters, which means that in the Asian Games at this level of competition, only three athletes can jump 7.80 meters.

In ten days, from a rookie who didn't even know basic long jump skills to an athlete who could win a medal in the Asian Games, anyone knows that this is an impossible task. So Director Ma thinks that Zhang Guan is doomed!

……

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

Zhang Guan originally felt that for himself, running should be the least need for practice, but when he really began to learn the long jump, Zhang Guan found that just a running aid contained a lot of knowledge.

The purpose of the run-up is to bring the body to the highest speed, and the average men's run-up distance is between 40 and 45 meters, and the pace during the run-up is 22 to 24 steps. When it comes to each athlete, his running distance will be more accurate, and the pace of the run will be a fixed number of steps. In the actual race, athletes also need to adjust the distance of the run-up according to the softness of the track, the coldness of the climate, whether it is downwind or headwind, and how physical strength is.

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

The run-up is followed by the jump, which is divided into three parts: the upper board, the cushion and the extension, each with different mechanical characteristics and specific requirements.

When you go on the board, you can't step on the reticle, which is the most basic requirement, and in terms of technology, there are requirements for the landing angle when jumping; In the buffering stage, there are also requirements for the maximum knee bending angle during the athlete's take-off leg and jumping; As for the extension stage, it is necessary to raise the center of gravity of the body as much as possible, which not only has technical requirements for the lower limbs, but also has technical requirements for the upper limbs.

After the take-off is the take-off stage, there are three main postures in the air: "crouching", "standing up" and "walking". The squat pose is one of the simplest and best postures to master; The difficulty of the upright pose is much greater than that of the squatting pose, and 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; The walking style is more conducive to maintaining the balance of the body in the air, and it is also more advantageous in the control of the landing position.

There are pros and cons to each of these three postures, although more and more people are starting to use the walking pose, but it does not mean that no one uses the other postures, even in the world's highest-level competitions, there are still athletes who use the squat in the air, such as the 2008 Olympic long jump champion Saladino, who likes to use the simplest squat.

In the final landing aspect, athletes are required to quickly bend their knees and stretch their calves forward when touching the sand, and then stand up forward with force. In the landing, it is absolutely taboo to land the butt part first or go to the ground with your hands first, and we have seen many athletes in the competition sitting in the sand pool after landing, but in fact, when their butt touches the ground, their body has already slid forward for a large distance, and the place where their butt touches the ground is actually behind the foot landing point.

……

It is not difficult for Zhang Guan to run, it is nothing more than to maximize the speed as much as possible, which is what Zhang Guan is best at.

For beginners in general, the first difficulty in the long jump is to turn running into a jump. The faster the running 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 perform the long jump, it seems that the speed of the running is quite fast, but in fact, "running" and "jumping" are separated, and the two movements are combined.

Zhang Guan has done a good job in this regard, after the skill of sprint jumping reaches the master level, Zhang Guan can better convert the kinetic energy of running into the kinetic energy of jumping.

But then the vacant part made Zhang Guan feel the difficulty. (To be continued.) )
