In front of the runway.
"Older, in this 400-meter sprint, can Zhang Guan do it? The difficulty of running 400 meters into 46 seconds is very difficult. You usually train Zhang Guan, what is his 400-meter technique?" Director Ma asked.
"To be honest, Zhang Guan's 400-meter technique is still inferior to other athletes of the national team." Yu Guizhuo changed his voice, then said: "But the physical talent is really good, and it is very good in the distribution of sports rhythm. perfect."
Director Ma seemed a little unclear, he said, "Old, you sound contradictory! The most difficult technique in this 400-meter sprint is the distribution of sports rhythm. Zhang Guan didn't say Zhang Guan's Is the technology bad?"
"The technology I said is not good is the basic technology." Yu Gui also said helplessly: "But he is really good in rhythm distribution, as stable as computer-controlled. I really have no way to come Explain. You will know after a while."
"Alright, Zhang Guan seems to be ready, let's get started!" Director Ma finished and signaled that he was ready to give orders.
...
"Everyone, prepare..." "Boom!"
With the sound of the gun that started, 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 fast and fast 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, and he has obtained 85% of the curve sprint effect. Then it started to accelerate along the inside of the track.
"There has been a lot of progress in cutting inside, but there are still problems with this pace. The pace is not big enough, the swing of the arm is not enough. The speed is not bad. The sense of rhythm is also very stable." Director Ma started inwardly Comment it.
Every athlete in the 400-meter event has some differences in running style, and the difference in running style has caused differences in technical characteristics. However, in the first 100 meters after the run, athletes tend to adjust their rhythm. If they quickly enter their own adaptive rhythm, it can be seen in the game that many big-name athletes did not score in the initial curve. Lead. The main reason is that they are adjusting their rhythm and entering the game as soon as possible.
In the first 100 meters, since the athlete just started, the athlete's physical strength is relatively sufficient. If it is the top-level competition in the Olympic finals, the time spent by the world's top athletes in the first 100 meters is about 11.50 seconds. If it takes less than 11 seconds, it means that you are running very hard, and the later physical strength is likely to be insufficient. It takes more than 12 seconds to indicate the saved physical strength, and then the straight track is likely to sprint quickly. Of course, if the competition is at a lower level, athletes will not do their best, and naturally they will not run out of such a good number.
Although the level of domestic athletes is not high. In the first 100 meters, it is generally around 12 seconds, and some athletes who like to run faster in the early stage can also reach the number of 11.5 seconds.
Zhang Guan showed the same sense of rhythm as foreign athletes. The first 100 meters took between 11.5 seconds and 12 seconds. It can be said that Zhang Guan performed well.
Next, Zhang Guan prepared to enter the second 100 meters, which is the straight area.
"Curved straights have also improved a lot, basically there are no flaws. It's just that the speed does not seem to change much compared to the previous curve. Is this learning the running style of European and American players?" Director Ma thought Continue to comment.
The second 100m is actually the least time of the entire 400m. Domestic athletes generally speed up some paces in the first straight. Significantly increase the speed, many people spend less than 11 seconds in this 100-meter stage.
European and American athletes also use the same running method, they can run within 10.5 seconds during this period. But there are also a large part of the world's most priced athletes who will not choose to force acceleration in the second 100 meters. They are more adjusting the pace to get higher speed.
Turning a curve into a straight road requires an adjustment. Previously Zhang Guan was weak at this point, but through practice, the process of cutting a straight road in a curve is already very familiar. At the same time, he is still continuing the 85% sprint effect brought by "incomplete sprint activation", so it seems that the speed has not been greatly improved.
The distance of this straight road is actually not long. Zhang Guan immediately turned into the curve, but when he entered the curve, the route was slightly off course, he had to adjust the route again in the curve and cut his body to run Inside.
"This straight road does not run well, and the course is off course. You have to lose a lot of time!" Director Ma frowned.
When the athlete enters the curve at the end of the straight, they will make adjustments 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 skilled at this point. When he makes adjustments in the corners again, the loss of time is a trivial matter, mainly affecting the overall rhythm.
The third hundred meters is a threshold for domestic athletes, especially the acceleration of the straight will make the body in a tired state. At this distance, the body will enter a state of slight hypoxia, and the speed will appear. decline. At this stage, athletes mainly adjust and accumulate energy to prepare for the final sprint. During this time, many domestic athletes will spend more than 12 seconds.
There are also many athletes who choose to adjust the rhythm in advance in the straight to two-thirds, so that the body will be better after entering the curve again, and can also sprint in advance.
If you did not choose to accelerate on the first straight, but kept the frequency, then your body will be much better when you enter the second corner, and you will have more choice in the next game.
Zhang Guan did not choose to slow down the rhythm in the second corner, but still proceeded 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. It is also the same after entering the second curve. Is this the kind of running method that is going to use Michael Johnson?" Director Ma stunned. . Immediately afterwards, I remembered that the legendary American sprinter Michael Johnson used this kind of running method.
The advantage of this running method is that you can save physical energy in the first and middle stages, and then get more speed during the later sprint; the disadvantage is that it may fall behind your 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. Up to now, many American athletes still use this running method. It is also a mainstream running method for European and American athletes.
Athletes who use this type of running are often explosive athletes. Although their rhythm in the early and middle stages is controlled evenly, when they want to accelerate, they will instantly increase their speed and make their opponents unprepared.
"How is it so old? How to teach Zhang Guan to use this running method. This running method has very high requirements on the body and requires a perfect distribution of physical strength." Director Ma glanced at something unclearly. Guidance, and then focused on Zhang Guan.
"According to this running method, the first sprint should be started at about 250 meters! So how will Zhang Guan choose next? Is it the sprint? Can he control it?"
Michael Johnson's running method is at 250 meters, which is when the curve is almost halfway. Athletes will change their rhythm and then start the first sprint, and if the world’s top athletes use this type of running, the third 100m will take almost 0.3 seconds slower than the second 100m.
This sprint will continue until it is about to go straight, and then there will be two changes:
One way to run is to sprint straight down to the end. However, after 250 meters of high-speed sports, even if the previous rhythm was used to reduce physical exertion, most athletes cannot maintain a sprint of up to 150 meters. Often, they do not have much strength until 350 meters.
Another way to run is to end the sprint before entering the straight, then quickly adjust the rhythm after entering the straight, then start the second sprint and go straight to the end. This method has more buffer than the first method, and can last longer and longer in the straight sprint later. However, the requirements on the body are extremely high, because the first sprint of about 250 meters will consume part of the physical strength, and the second sprint will be performed immediately after entering the straight path. If the physical quality does not meet the requirements, the explosive force will not be able to output, and the sprint will not be at all. stand up. At the same time, quick adjustment after the first sprint is also a very important technique. This technique cannot be mastered by every athlete.
"It's about 250 meters, so Zhang Guan should prepare for a sprint, but I don't know if he wants to sprint in the end, or choose a second sprint? The difficulty of the second sprint is too high, he should choose a sprint in the end Let's run! But after all, Zhang Guan's rhythm in the first half is well controlled. If he chooses to enter the straight and sprint for the second time, it is not impossible." Director Ma stared at Zhang Guan closely and began to look forward to Zhang Guanxia One step action.
At 250 meters, Zhang Guan is still running at the same speed as the original rhythm.
At 260 meters, Zhang Guan also did not change rhythm.
The same is true for 270 meters.
He was still at the same pace as when he started.
"What's the matter? What is Zhang Guan doing? It's almost the end of the straight, why don't you sprint? Is there no physical strength? No, although the speed in front of him is not slow, but there is no obvious change in rhythm. There must be reserves for physical strength." Director Ma has been unable to understand what Zhang Guan is going to do, so Director Ma stared at Zhang Guan so straight into the straight.
"Go straight!"
At the same time, Zhang Guanmeng began to accelerate, and the speed was raised in an instant.
"I started sprinting after entering the straight! What the is happening! It's too late at the time. Is this the kind of outdated running method that happened decades ago? How do you teach old things? Don't teach things that are improving, even teach This outdated running method of the last century? This running method has already been eliminated by the times!" Director Ma began to blame for guidance,
But then, he found that the speed of the crown on the track seemed to be somewhat different. Specifically, it seems too fast.
"Why is the sprint speed so fast! Is he really running 400 meters? Instead of running 200 meters?" Director Ma at this time had grown his mouth in surprise.
Zhang Guan hasn't changed his rhythm until the moment when he entered the straight road. It was also at this moment that he turned off the "Incomplete Sprint Activation" skill.
The 85% sprint effect and the 100% sprint effect seem to be only a 15% difference, but as the final stage, Zhang Guan does not have to worry about physical strength and rhythm. All he has to do is run 100 meters In that way, brainless forward!
At this time, Zhang Guan's physical fitness is still relatively abundant. The uniform rhythm in the front will be more energy-saving, and the incomplete sprint activation is anti-natural. It can only consume 50% of the sprint skills. That is to say, Zhang Guan is now The physical energy consumption is definitely much less than the athlete who ran into the last straight under the same conditions.
Then he showed a speed that was not a 400-meter sprint! (To be continued.)
ps: The second is delivered. Because I want to write 400 meters, the level of understanding of this project is similar to that of everyone. When I wrote this plot, I bought a dozen related papers on the Internet to learn about 400 meters. The running methods and technical characteristics of top athletes were analyzed. I don’t know if anyone else has specifically searched for papers to write an online novel. Anyway, I try to be more rigorous! Do you still have a monthly pass? If you don’t have a monthly pass, you can get a few recommended tickets! Thank you all.
