Chapter 155: 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 Athletics Team, he was usually doing some administrative work. He never taught any special sports or used the identity of the coach to appear on the training ground.
"It seems that you don't know. Director Ma used to be a long jump coach." Liu Feiren then explained, "Director Ma was in a special era when he was 17 or 18 years old. At that time, the physical training of the team was not very good, 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 became a graduate student majoring mainly in track and field teaching and training. After graduating from college, he went to join the national team as a coach less than ten years ago to coach athletes."
Liu Feiren then added, "It is said that Director Ma has made great efforts in long jump training and has published several top-level training methods. Now the training system for the long jump projects of various domestic training bureaus was proposed by Director Ma back then. I have never seen Director Ma coach an athlete, but I heard some predecessors said that Director Ma is a high-level coach and is very strict. It is said that the Asian long jump record holder in our country was trained by Director Ma."
"I didn't think Director Ma was so powerful. I thought he was born in administrative logistics. I didn't expect him 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 didn't you say..." Zhang Guan smiled embarrassedly, "Isn't this me trying to reach my potential."
"Long jumps are not as easy as you think. It requires not only the body but also the techniques! Techniques!" Director Ma especially emphasized the word "techniques", obviously implying that Zhang Guan's ability to learn technique is poor.
"Technical aspects can be practiced slowly, or you should 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 long jump event.
From the perspective of the long jump coach, Zhang Guan has sufficient 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 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. At present, Zhang Guan's 400-meter dash has not been perfected yet, so he should not practice new events anymore. People's energy is limited. Zhang Guan is already working on three sprint events at the same time. If he joins the long jump, his energy consumption will be increased, it is likely to affect the level of other projects as well.
Director Ma is not a very unreasonable person. He knows that Zhang Guan is a very assertive person. If he refuses Zhang Guan directly now, it is not a suitable choice. Director Ma hopes to be able to lead by the initiative. Let Zhang Guan give up the idea of practicing the long jump.
"Long jump is not so easy to be able to practice. Although a strong sprinter will practice long jump, the level is certainly not bad, but everything is not absolute. If you 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 event award ceremony of the Central People's Sports People will happen just ten days later, so I will give you these ten days. If you can prove that you are suitable for long jump practice, I will allow you to practice the long jump. I will personally make a training plan for you; but if you can't prove yourself suitable for long jump practice in ten days, then give up on the idea of practicing long jump and just practice the 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 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 six jumps, as long as you have you can meet the standards of national sports athletes once, how about it?
"No problem, that's perfect!" 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 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! The long-jump isn't like this." Director Ma looked like a scheming master and said, "The national athlete's achievement in the long jump is 7.8 meters!"
...
Although the strength of the national team's long jump is not strong in the world, it is a first-class level in Asia. Among athletes' technical grade standards, the international standard for long-jumping athletes is 8 meters, the standard for national-level athletes is 7.80 meters, and the B-mark for the Olympics is 8.05 meters.
If you can jump 7.80 meters, you will be eliminated at the Olympics, but you will 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 past the 7.80-meter mark.
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 would know that this is an impossible task. Therefore, Director Ma felt that he defeated Zhang Guan!
...
Long jump consists of four parts: running, taking off, flying, and landing.
Zhang Guan originally thought that running should be practiced the least, but when he started to learn long jump, Zhang Guan found that only running is simple, but it contains a lot of knowledge.
The purpose of running is to get your body to 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 according to 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 technique requirements for the starting posture of the run-up, the acceleration method of the run-up, and so on. 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: the 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 buffer stage, there is also a maximum requirement for knee bending angle during the jumping of the athlete's jumping leg. As for the stage of stretching, the center of gravity of the body should be raised as much as possible, which not only has technique requirements for the lower limbs, but also technique 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 obtaining a good landing posture, and walking is more conducive to keeping the body balanced in the air, and it also has its advantages in landing posture control.
Each of these three poses has its pros and cons. Although more and more people started to use walking, it does not mean that other poses are not used by anyone. Even in the highest level of competition in the world, 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, the athletes are required to quickly bend their knees and extend their calves before 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 a taboo to drop the butt part first or go to the ground with the hand first, and we saw in the game that many athletes were sitting in the sand pool after landing, when in fact their butt hit the ground, The body has slid forward a great distance, and the place where their butt touches the ground should be after the foot touches.
...
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 Guan is best at.
For the average beginner, the first difficulty in the long jump is to turn running into a 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 perform the long jump, they seem to run fast, but in fact "run" and "jump" are not separate, the two actions are combined.
On this point, Zhang Guan did a good job. After upgrading the sprint jump skill point to the master level, Zhang Guan could convert the kinetic energy of the run-up into the kinetic energy of the take-off.
But then the vacated part made Zhang Guan feel the difficulty.
