Chapter 138 The King of Athletics: 400-meter test (second update)

before the runway.

"Old Yu, is Zhang Guan good at this 400-meter sprint? It is very difficult to run 400 meters in 46 seconds. You usually train Zhang Guan, how is his 400-meter technique?" Director Ma asked.

"To be honest, Zhang Guan's 400-meter skills are still inferior compared to other athletes in the national team." Director Yu changed his voice, and then said: "However, his physical talent is really good, and he is very good at distributing movement rhythm. Perfect."

Director Ma seemed a little confused, and he said, "Old Yu, what you said sounds a little inconsistent! The most difficult technique in this 400-meter sprint is the distribution of movement rhythm. Didn't Zhang Guan just say that about Zhang Guan?" Is the technique bad?"

"The bad technique I'm talking about is the basic technique." Director Yu also said helplessly: "But he is really good at rhythm distribution, as stable as if controlled by a computer. I really have no way to do this. Explain. You'll find out after a while."

"Alright, Zhang Guan seems to be ready, let's get started!" Director Ma finished speaking, indicating that he was ready to issue an order.

...

"Everyone on their positions, get ready..." "Boom!"

With the sound of the starting gun, Zhang Guan started to run. The start of the 400-meter sprint is not as extreme as the 100-meter pursuit of reaction time, but the main purpose is to facilitate and quickly enter the rhythm after the start, so Zhang Guan's start is not as fast as the 100-meter.

But Zhang Guan has activated the "incomplete sprint activation" skill, he obtained 85% of the curve sprint effect, and then began to accelerate along the inner line of the track.

"There has been great progress in cutting the inside line, but there are still problems with the steps. The steps are not big enough, and the swing of the arms is not enough. The speed is not bad, and the sense of rhythm is also very stable." Director Ma began in his heart. Review it.

Every athlete in the 400-meter event has some differences in running style, and the difference in running style has caused the difference in technical characteristics. However, in the first 100 meters after running, athletes often focus on adjusting their rhythm. If they quickly enter their own adapted rhythm of the game, it can be seen in the game that many big-name athletes did not achieve success in the initial corner. Leading, the main reason is that they are adjusting the rhythm and entering the game state as soon as possible.

For the first 100 meters, due to the fact that the athletes have just started, the physical strength of the athletes is relatively sufficient. If it is the top competition like the Olympic finals, the top athletes in the world will take about 11.50 seconds for the first 100 meters. If the time is less than 11 Seconds, it means that you are running very hard, and you may not have enough physical strength in the future. If you spend more than 12 seconds, it means that you have saved your physical strength, and you may have to sprint quickly on the straight track. Of course, in some low-level competitions, the athletes will not do their best, and naturally they will not run such good numbers.

Although the level of domestic athletes is not high, the first 100 meters is generally around 12 seconds. Some athletes who like to run faster in the early stage can also run to the figure of 11.5 seconds.

Zhang Guan's sense of rhythm is the same as that of foreign athletes. The time for the first 100 meters is between 11.5 and 12 seconds. It can be said that Zhang Guan's performance is quite satisfactory.

Next, Zhang Guan is about to enter the second 100 meters, which is also the straight track area.

"Curves and straights have also improved a lot, and there are basically no flaws. Compared with the curve just now, the speed does not seem to have changed much. Is this learning from European and American runners?" Director Ma thought. Continue to comment.

The second 100 meters is actually the least time-consuming stage of the entire 400 meters. Domestic athletes generally speed up their pace on the first straight and greatly increase their speed. Many of them spend less than 11 seconds on this 100-meter stage.

European and American athletes also use the same running method, and they can run within 10.5 seconds in this section. But there are also a large number of the most expensive athletes in the world who do not choose to forcibly accelerate in the second 100 meters. They adjust their steps more to obtain higher speeds.

Changing from a curve to a straight requires an adjustment. Previously, Zhang Guan was weak at this point, but through practice, the process of cutting a straight from a curve has become very proficient. At the same time, he is still continuing the 85% sprint effect brought about by the "incomplete sprint activation", so it seems that the speed has not improved much.

The distance of this section of straight road is actually not long, and Zhang Guan immediately turned into the curve again, but when he entered the curve, his route deviated a bit, so he had to adjust his route again in the curve, cutting his body until he ran to the corner. inside.

"It's not a good run on the straight and turning road. The route is deviated, and a lot of time must be lost!" Director Ma frowned.

When the athletes enter the curve at the end of the straight, they will adjust in advance to ensure that they run along the inside of the curve as soon as they enter the curve. Zhang Guan is not very proficient in this technique. When he makes adjustments in the corner, the loss of time is a small matter, and the main thing is that it will affect the overall rhythm.

The third 100 meters is a threshold for domestic athletes, especially the acceleration of the straight track will make the body in a state of fatigue. During this distance, the body will enter a state of slight hypoxia, and the speed will appear decline. At this stage, athletes are mainly adjusting and accumulating energy, preparing for the final sprint. During this period, many domestic athletes will spend more than 12 seconds.

There are also many athletes who choose to adjust the rhythm in advance when they run to two-thirds of the straight, so that their physical condition will be better after entering the corner again, and they can also sprint in advance.

And if you don't choose to accelerate on the first straight, but keep the frequency, then your body will be in much better condition when entering the second corner, and you will have more options for the next race.

Zhang Guan did not choose to slow down the pace at the second corner, but was still advancing at the same pace as before.

"This is not a common running method for domestic athletes. There is no change in the rhythm of the first 200 meters, and it is the same after entering the second corner. Is this the kind of running method that Michael Johnson is going to use?" Director Ma was stunned. , Then I immediately remembered that the legendary American sprinter Michael Johnson seemed to use this kind of running method.

The advantage of this running method is that it can save energy in the early and mid-term, and then gain greater speed in the subsequent sprint; the disadvantage is that it may lag behind the opponent in the first half. In the era of Michael Johnson, this running method was very popular, and Michael Johnson also conquered the whole world with this running method. So far, many American athletes are still using this running method, and it can be regarded as a mainstream running method for European and American athletes.

Athletes who use this running method are often those with strong explosive power. Although they control the rhythm very evenly in the early and mid-term, when they want to accelerate, they will increase their speed instantly, catching their opponents by surprise.

"What did Lao Shi do? How did he teach Zhang Guan to use this kind of running style? This kind of running style is very demanding on the body, and requires a perfect distribution of physical strength." Director Ma glanced at Yu in confusion. Guidance, and then focused on Zhang Guan.

"According to this running method, the first sprint should start at about 250 meters! So what will Zhang Guan choose next? Will he sprint to the end? Can he control it?"

In Michael Johnson's running method, at 250 meters, that is, when the curve is almost halfway through, the athlete will change the rhythm and then start the first sprint. If the world's top athletes use this running method , the time taken for the third 100 meters is almost only 0.3 seconds slower than the second 100 meters.

This sprint lasts until just before entering the straight, and then two variations occur:

One kind of running method is to sprint directly until the end, but after a high-speed movement of 250 meters, even if the rhythm is used to reduce physical exertion before, most athletes cannot maintain a sprint of up to 150 meters, and often reach 350 meters. There is not much power left after about one meter.

Another way of running is to end the sprint before entering the straight, then quickly adjust the rhythm after entering the straight, and then start the second sprint to go straight to the finish line. This method has a little more buffer than the first method, and it can last farther and longer in the subsequent straight sprints, but it is extremely demanding on the body, because the first sprint of about 250 meters will consume part of the physical strength , After entering the straight, immediately carry out the second sprint. If the physical fitness is not up to the requirements, the explosive power will not be released, and the sprint will not be possible at all. At the same time, quick adjustment after the first sprint is also a very important technique. Not every athlete can master this technique.

"It's about to reach 250 meters, so Zhang Guan should be ready to sprint, but I don't know whether he should go to the end or choose a second sprint? The difficulty of the second sprint is too high, he should choose to go to the end It’s your running style! But having said that, Zhang Guan’s rhythm in the first half is very good, if you choose to enter the straight and then sprint, it is not impossible.” Director Ma stared at Zhang Guan closely, and began to look forward to Zhang Guan’s next move one step action.

At 250 meters, Zhang Guan was still running at a constant speed according to the original rhythm.

At 260 meters, Zhang Guan also did not change his rhythm.

270 meters, too.

He still has the same rhythm as when he started.

"What's going on? What is Zhang Guan going to do? It's almost the final straight, why don't you sprint? Could it be that he has no energy? No, although his speed in front of him is not slow, there is no obvious change in rhythm. There must be some reserves in physical strength." Director Ma couldn't understand what Zhang Guan was going to do, so Director Ma just stared helplessly at Zhang Guan and entered the straight road.

"Entering the straight road!"

At the same time, Zhang Guan started to accelerate fiercely, and the speed increased in an instant.

"Start sprinting after entering the straight! What's the matter! It's too late. Is this the kind of outdated running style decades ago? How did the old man teach it? If you don't teach something that is improved, you actually teach it. This outdated running method from the last century? This running method has already been eliminated by the times!" Director Ma began to blame the guidance again in his heart,

But then, he found that Zhang Guan's speed on the track seemed to be a little different. Specifically, it seems to be a little too fast.

"Why is the sprint speed so fast! Is he really running 400 meters? Not 200 meters?" At this time, Director Ma had already opened his mouth in surprise.

Zhang Guan didn't change his rhythm until the moment he entered the straight, and then he started. It was also at this moment that he turned off the "incomplete impulse activation" skill.

The sprint effect of 85% and the sprint effect of 100% seem to be only 15% different, but as the last stage of the race, Zhang Guan does not need to worry about physical strength or rhythm. All he has to do is run 100 meters In that way, rush forward without thinking!

At this time, Zhang Guan's physical energy is still relatively abundant. The uniform rhythm in front will save energy, and the incomplete sprinting activity is even more against the sky. It can only consume 50% of the sprinting skill. That is to say, Zhang Guan is now The physical energy consumption of the athlete is definitely much less than that of athletes running into the final straight under the same conditions.

Then, he showed a speed that doesn't belong in the 400-meter dash!

The second is delivered. Because I have to write 400 meters, the level of understanding of this project is similar to that of everyone. When writing this plot, I bought more than a dozen related papers on the Internet to learn about 400 meters. The running style and technical characteristics of the top athletes are analyzed. I don't know if other people have checked papers specifically for writing an online novel, anyway, I'm trying to be as rigorous as possible! By the way, do you still have a monthly pass? If you don’t have a monthly pass, it’s okay to give a few recommended tickets! Thank you all.
