Coach Sun has been with Liu Feiren, and he found that Liu Feiren has been watching Zhang Guan's training, and said with a smile: "What, do you want to try it too?" ”

Liu Feiren shook his head: "I'll just focus on one thing." However, I always thought that Zhang Guan's 400-meter run was a bit weird. ”

"You see that, too?" Coach Sun continued: "This is not only strange, it is simply different, how can an athlete run like this now!" ”

Liu Feiren didn't quite understand, so Coach Sun said: "The running method commonly used by our domestic athletes is: the first 100-meter rhythm, the second 100-meter straight line acceleration, the third 100-meter rhythm, and the fourth 100-meter sprint. ”

Liu Feiren nodded, he knew this. In the 400-meter sprint, after the start is in the corner, because the physical strength is more sufficient at this time, so the athlete runs more easily, and at this stage, the athlete also needs to enter the rhythm of the exercise as soon as possible, and the physical strength will save a lot by running according to the rhythm. And when they enter the straight, the athlete will choose to speed up, and will use about 90% or even 95% of the force to run.

After entering the second corner, which is the most uncomfortable stage for athletes, due to the acceleration of the straight line, the physical strength has been greatly consumed, so in the second corner will feel fatigue or a slight feeling of suffocation, which is a normal physiological phenomenon brought about by anaerobic exercise, and athletes will also slow down slightly in the second corner to adjust. After that, it's about the final straight, which is how fast you can run until you cross the line.

Coach Sun next to him then explained: "I am also observing Zhang Guan, he does not use this running style, his first 300 meters, whether it is a curve or a straight road, is a rhythm run, and then in the final straight will sprint violently." I secretly asked Lao Yu yesterday, and he said that Zhang Guan is not very good at switching rhythms between corners and straights, so he simply uses this way of running. ”

"Hahaha, it turns out that I can't learn! He also has such a messy time? I thought he had innovated a new 400m run! Liu Feiren laughed.

"I think it's funny, too. Because I can't learn and choose another way of running, Zhang Guan should be the first! However, this is not an innovative way of running, but a very retro way of running. Probably when this kind of running appeared, your parents' generation was just born! Coach Sun said.

Liu Feiren listened quietly, waiting for Coach Sun to continue to answer, and Coach Sun continued: "When there was a 400-meter dash at the beginning, no one knew how to run, just pulled their legs and ran forward, and at that time, the athletes were actually running blindly; Later the athletes found out that if they ran at the same pace. It will save a lot of physical strength, and then use this physical strength for the final sprint, which will have a good effect, so at that time, the 400-meter running method is almost a rhythm in the front 300 meters, and the straight sprint in the back, which is Zhang Guan's current running method. ”

"But when everyone uses this style of running, there is nothing to watch the race, especially when the athletes are similar, and everyone runs in front of them. When it came to the final straight track, there was not much difference, and it felt like watching a 100-meter sprint lacking physical strength. Later, more modern running methods began to appear, such as the first corner into the straight. Then the speed of the straight road is adjusted into the corner, and there is also a sprint at 250 meters, which is commonly used by European and American athletes, and so on. Especially after the emergence of Michael Johnson in the United States, there has been a great development in sprinting technology. The 400-meter sprint technology in our country is actually very backward, and now the West Asian players and Japanese players. It has begun to adopt the technical running methods of some European and American countries. ”

Liu Feiren nodded, and then asked: "Isn't that crown behind the times with this retro running style?" Won't you be very passive when you play? ”

"Possibly. But not entirely sure. In the 400-meter sprint, each athlete will have their own running style and rhythm distribution method. Since athletes don't have to be paralleled, there are relatively few tactical considerations, as long as they run at their own pace, so it's actually a test of strength. Coach Sun thought for a while, and then continued: "Zhang Guan's 100-meter sprint is the first in the world, and it is much stronger than other domestic athletes, I think if he relies on physical fitness alone, he will run 400 meters better than many professional 400-meter athletes in China!" ”

Field Management Center

There was a knock on the door, and Director Luo shouted "Please come in", and then saw Director Ma push the door in.

"Director, I have something to report to you." Director Ma sat directly opposite Director Luo, and then said, "There's something about Zhang Guan." ”

"Zhang Guan? What happened to him? Director Luo's heart tightened, the turmoil of falling in love had just ended, so there shouldn't be any new problems!

"That's right, about East Asian athletes, Zhang Guan said that he doesn't want to participate in the 100-meter sprint!" Director Ma spoke.

"Not participating? No way! Director Luo was suddenly a little annoyed, he suddenly felt that what the annoying President Qu said was quite reasonable, maybe it was really not good to give athletes too much autonomy, how long has it been, Zhang Guan actually refused to participate!

"Director, don't get me wrong, Zhang Guan proposed not to participate in the 100-meter sprint, but to participate in the 200-meter sprint and 400-meter sprint instead." Director Ma continued.

"Oh? 200 meters? 400 meters? Can he? Director Luo immediately calmed down, and the anger just now disappeared without a trace.

"I think the 200m should be fine, I've seen him run the 200m, he has the strength to run 20.20 seconds in the 200m dash. But 400 meters I can't guarantee it. Director Ma explained

"20 seconds in 20 seconds? That's 0.3 seconds faster than the national record! Director Luo was taken aback, and then said with relief: "Also, he is more than half a second faster than other domestic athletes in the 100-meter event, and it is normal for the 200-meter to be 0.3 seconds faster." So it's not far from the Asian record? Is it possible to win a medal in a world competition? ”

"It may be close now, but in two or three years, it's definitely possible. If it is a competition in Asia, there will be no problem with medals, and there is also a hope for gold medals! Director Ma replied.

"In two or three years, that is, in time for the next Olympic Games!" Director Luo suddenly became excited, he had already begun to imagine Zhang Guan winning the 100-meter and 200-meter championships at the next Olympic Games, and then he said: "The 200-meter sprint of East Asian athletes, let him try it." But 400 meters ......"

Director Luo hesitated, 400 meters and 200 meters are different. If you compare it to 100 meters, the span is larger.

Director Ma next to him said: "I heard Lao Yu say that although Zhang Guan's 400-meter technology is still lacking, the rhythm is quite good, but I haven't seen it with my own eyes, why don't we measure it?" If you run well, let him go. ”

Director Luo nodded: "Okay, test!" If he can run for 46 seconds, let him go to the race. ”

……

In the restaurant of the Xinzhuang training base, Liu Fei and Zhang Guan happened to sit facing each other.

"Today's beef is really good." Liu Feiren picked up another piece of beef stew, and then asked, "I heard that you applied not to participate in the 100-meter sprint of the East Asian Games." Switching to 200m and 400m? ”

Zhang Guan nodded: "There are only a few people participating in the East Asian Games, 100 meters is not difficult, and the strongest Japanese even run in for 10 seconds, and they have no passion to abuse vegetables." So it's better to leave the opportunity to other athletes in our country, if I don't participate in the 100 meters, I can control a place, and let other athletes go on the field, experience it, and increase experience. A few days ago, during the Athletics Gold Grand Prix. Hu Kai played well, ran fifth, and maybe he could enter the A standard in the future. ”

"That's right, you're half a second faster than others. It's not fun to run. You've been running a good 200-meter meter lately, and I've heard that your training level can be basically maintained within 20 seconds, and if you change to electronic timing, it's just over 20 seconds, and it's no problem to dominate Asia. Liu Feiren took a sip of soup. Then he said: "But your 400-meter run is really miserable! Although I haven't run 400 meters, I can see that your skills are not very good, especially when you are just starting to practice. It's just amateurish. ”

"Don't worry, practice slowly, after all, 400 meters is too demanding for technology. I guess I'll be better by the beginning of next year after two months of serious practice. Zhang Guan continued: "This afternoon, Director Ma is going to come to test me, saying that as long as the 400-meter run is 46 seconds, let me go to the competition. ”

"46 seconds? Such a high demand! Liu Feiren leaned forward slightly, and then asked, "Are you confident?" ”

"No problem, isn't it 46 seconds!" Zhang Guan said confidently.

"Now I really envy you for practicing sprinting, running 200 meters can be combined with 100 meters or 400 meters, like I practice hurdles, I can only run 110 meters, it's really boring." Liu Feiren sighed.

"Why don't you also apply and participate in the 4x100m for East Asian athletes? It doesn't matter if you can't run fast, I'll carry it for you. ”

Liu Feiren shook his head: "Forget it, in the 4 x 100-meter relay race, there will definitely be no problem for the current lineup to win the championship, so I won't make trouble." ”

……

The men's 400-meter sprint level of the national team is relatively low in the world, and if the national team's 100-meter sprint can still be in the forefront of Asia, then the 400-meter sprint can only be regarded as the level of the lower middle stream in Asia. The international athletes in this event achieved the standard time of 45.74 seconds, and there are only two in the country, and the national athlete achieved the standard time of 47.60 seconds, which is not very many. The 400m dash was marked by 45.55 seconds at the Olympics and 45.95 seconds at the B standard, but in the two years leading up to the Athens Olympics, no one from the national team ran into the Olympic B standard, which meant that no one competed in the 400m race at the Athens Olympics.

The 46 seconds mentioned by Director Luo is actually a top result in China, and in the 400-meter sprint event, only three athletes in China have run 46 seconds before this, two are active athletes and one is a retired player. A time of 46 seconds would have a good chance of winning a medal even in Asian athletics.

In the domestic general competition, the 400-meter sprint event can run to 46.5 seconds to win the championship, while in the recently concluded 10th Games, the top three times are 46.15 seconds, 46.44 seconds and 46.66 seconds.

So, 46 seconds, in fact, is quite difficult. (To be continued.) )
