Before the runway.
"Old Yu, can Zhang Guan do this 400-meter dash? It is very difficult to break 46 seconds in 400 meters. 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 continued: "But his physical talent is really good, and he is very good in the distribution of movement rhythm. Perfect."
Director Ma seemed a little unclear, and he said: "Lao Yu, what you said sounds a bit inconsistent! The most difficult skill in this 400-meter dash is the distribution of movement rhythm. Didn't Zhang Guan just say that? Is the technique bad?"
"The bad technique I'm talking about is 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. Explanation. You’ll know after a while.”
"Okay, Zhang Guan seems to be ready, let's get started!" After Director Ma finished speaking, he signaled that he was ready to issue an order.
…
"Everyone is in position, ready..." "Bang!"
As the starting gun sounded, Zhang Guan started to take off. 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 quickly enter the rhythm after the start, so Zhang Guan's start is not as fast as the 100-meter sprint.
But Zhang Guan had already activated the "Incomplete Sprint Activation" skill. He obtained 85% of the corner sprint effect, and then began to accelerate along the inside of the track.
"There has been great progress in cutting inside, but there are still problems with the pace. The steps are not big enough, and the arms are not swinging enough. The speed is not bad, and the rhythm is very stable." Director Ma began to think in his heart. Comment up.
Every athlete in the 400-meter event has some differences in running style, and the differences in running style lead to differences in technical characteristics. However, in the first 100 meters after running, athletes often focus on adjusting their rhythm to quickly enter their own adapted competition rhythm. Therefore, it can be seen in the competition that many big-name athletes did not achieve success in the initial curve. The main reason for taking the lead is that they are adjusting their rhythm and entering the game as quickly as possible.
In the first 100 meters, since they have just started, the athletes have sufficient physical strength. If it is the top competition like the Olympic finals, the time used by the world's top athletes in the first 100 meters is about 11.50 seconds. If the time is less than 11. Seconds means that you ran very hard, and your physical strength may be insufficient later. Taking more than 12 seconds indicates that you have saved your physical strength, and you may need to sprint quickly on the straight track. Of course, if there are competitions at lower levels, the athletes will not try 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 11.5 seconds.
Zhang Guan's rhythm was the same as that of foreign athletes. The time for the first 100 meters was between 11.5 seconds and 12 seconds. It can be said that Zhang Guan's performance was quite satisfactory.
Next, Zhang Guan prepares to enter the second 100 meters, which is the straight area.
"I have also improved a lot when turning into straights, and there are basically no flaws. It's just that the speed does not seem to have changed much compared to the curves just now. Are you learning the running methods of European and American players?" Director Ma thought. Continue to comment.
The second 100 meters is actually the shortest stage of the entire 400 meters. Domestic athletes generally speed up the pace on the first straight and increase their speed significantly. Many people spend less than 11 seconds in 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 forcefully accelerate in the second 100 meters. They more often adjust their stride amplitude to obtain higher speeds.
Changing from a corner to a straight requires an adjustment. Zhang Guan was weak in this area before, but through practice, he has become very proficient in the process of turning into a straight. At the same time, he is still continuing the 85% sprint effect brought about by "incomplete sprint activation", so it seems that the speed has not improved much.
The straight distance was actually not very long. Zhang Guan immediately turned into the curve again. However, when he entered the curve, his route deviated a little. He had to adjust the route again in the curve and cut his body until he ran into the corner. inside.
"The straights and turns were not run well. The route went astray. A lot of time must have been lost!" Director Ma frowned.
When athletes enter a curve at the end of a 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 proficient in this technique. When he makes adjustments in corners, the time lost is not a big deal, but it mainly affects the overall rhythm.
The third 100 meters is a threshold for domestic athletes. Especially the acceleration on the straight will put the body in a state of exhaustion. During 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 strength in preparation for the final sprint. During this period, many domestic athletes will take more than 12 seconds.
There are also many athletes who choose to adjust their rhythm in advance two-thirds of the way down the straight, so that their body condition will be better after entering the curve again, and they can also sprint ahead of time.
And if you don't choose to accelerate on the first straight, but keep the frequency, then your physical condition will be much better when entering the second corner, and you will have more options in the next race.
Zhang Guan did not choose to slow down at the second corner, but continued to advance at a similar pace to before.
"This is not a common running method for domestic athletes. There is no change in the rhythm in the first 200 meters, and it is the same after entering the second corner. Is this the kind of running method that we are going to use Michael Johnson?" Director Ma was stunned. , and then immediately remembered that the legendary American sprinter Michael Johnson seemed to use this 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 during the subsequent sprint; the disadvantage is that it may fall 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 entire world with this running method. Up to now, many American athletes are still using this running method, and it can be regarded as a mainstream running method among European and American athletes.
Athletes who use this running method are often athletes with strong explosive power. Although their rhythm is evenly controlled in the early and mid-term, when they want to accelerate, they will increase their speed instantly, catching their opponents off guard.
"What did you do, Lao Yu? How do you teach Zhang Guan to use this running method? This running method is very demanding on the body and requires a perfect distribution of physical strength." Director Ma glanced at Yu with some confusion. Guidance, and then focused his attention 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, which is almost halfway through the curve, the athlete will change his rhythm and then start the first sprint. And the top athletes in the world, if they use this running method , the time spent on the third 100 meters is almost only 0.3 seconds slower than the second 100 meters.
This sprint will continue until it is about to enter the straight, and then there will be two changes:
One way to run is to sprint straight to the finish line. However, after 250 meters of high-speed movement, even if the rhythm is used to reduce physical exertion, it is impossible for most athletes to maintain a sprint of 150 meters, often to 350 meters. There is not much strength left around 1 meter.
Another way to run is to end the sprint before entering the straight line, then quickly adjust the rhythm after entering the straight line, and then start the second sprint and go straight to the finish line. This method has more buffer than the first method and can last farther and longer in the subsequent straight sprint, but it is extremely demanding on the body, because the first sprint of about 250 meters will consume some of your physical strength. , sprint for the second time immediately after entering the straight. If your physical fitness does not meet the requirements, you will not be able to produce explosive power, and you will not be able to sprint at all. At the same time, quick adjustment after finishing the first sprint is also a very important skill. Not every athlete can master this skill.
"It's about to reach 250 meters, so Zhang Guan should be ready to sprint. I just don't know if he will sprint to the end or choose a second sprint? The difficulty of the second sprint is too high, so he should choose to sprint to the end. His running style! But having said that, Zhang Guan has a good grasp of the rhythm in the first half. If he chooses to sprint a second time after entering the straight, 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 the same pace as before.
At 260 meters, Zhang Guan also did not change his rhythm.
270 meters, too.
He still had the same rhythm as when he started.
"What's going on? What is Zhang Guan doing? We're almost on the final straight, why aren't you sprinting? Is it because you have no energy? No, although the speed in front of him is not slow, there is no obvious change in the rhythm. I must still have some physical reserves." Director Ma could no longer understand what Zhang Guan was going to do, so Director Ma just watched Zhang Guan enter the straight.
"Into the straight!"
At the same time, Zhang Guan fiercely began to accelerate, and the speed increased in an instant.
"I started sprinting after entering the straight line! What's going on! The timing is too late. Is this the kind of running method that was outdated decades ago? How did the old man teach it? If you don't teach things that are advanced, you actually teach them. This outdated running method from the last century? This running method has long been eliminated by the times!" Director Ma began to blame Guidance again,
But then, he discovered that Zhang Guan's speed on the track seemed to be a little different. To be specific, 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 was already open-mouthed in surprise.
Zhang Guan never changed his rhythm until the moment he entered the straight. It was also at this moment that he turned off the "Incomplete Sprint Activation" skill.
There seems to be only a 15% difference between the 85% sprint effect and the 100% sprint effect. However, as the last stage of the race, Zhang Guan does not have 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 even rhythm in the front will save physical energy, and the incomplete sprint activation is incredible. It can only consume 50% of the sprint skill. In other words, Zhang Guan is now The physical energy consumption of an athlete is definitely much less than that of an athlete running into the final straight under the same conditions.
Then, he showed speed that was not part of the 400-meter dash!
The second update is delivered. Because I have to write about 400 Meters, I know about this project about the same as everyone else. When I was writing this episode, I went online to buy a dozen related papers to learn about 400 Meters. Some of the papers also provided some insights into certain worlds. The running methods and technical characteristics of top athletes are analyzed. I don’t know if other people have checked papers specifically to write an online novel. Anyway, I try to be as rigorous as possible! By the way, do you still have monthly passes? If you don’t have a monthly pass, you can give me a few recommendation votes! Thank you.
