Test 400 meters

In front of the runway.

"Old Yu, in this 400-meter sprint, can Zhang Guan do it? The difficulty of running into 46 seconds in 400 meters is very difficult. You usually train Zhang Guan, how 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 Gui changed his voice, then said, "But the physical talent is really good, and it is very good in the distribution of sports rhythm, which is perfect."

Director Ma seemed a little unclear, he said, "Old Yu, you sound contradictory! The most difficult technique in this 400-meter sprint is the distribution of sports rhythm. Is the technology bad?"

"The technology I meant is that he is not good with the basic technology." Coach Yu also said helplessly, "However, he is good at rhythm allocation, as if he is controlled by a computer. It is stable, I have no way to explain. You will know after a while."

"Alright, Zhang Guan seems to be ready, let's get started!" Director Ma finished, indicating that he was ready to give orders.

...

"Everyone, prepare..." "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 a 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, so he obtained 85% of the curve sprint effect, and then began to accelerate along the track inside.

"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, and the sense of rhythm is also very stable." Director Ma stated inwardly.

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 adaptive rhythm, it can be seen in the game that many big-name athletes did not score in the initial curve. The main reason for leading is that they are adjusting their rhythm and entering the game as soon as possible.

In the first 100 meters, the athletes have more physical strength because they have just started. 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 their running is very hard, and the back physical strength is likely to be insufficient. It takes more than 12 seconds to indicate the saved physical strength, and then on the straight track, they are likely to sprint. Of course, if the level is lower, the athletes will not do their best, and naturally, they will not run into such a good number.

Although the level of domestic athletes is not high, the first 100 meters are generally around 12 seconds. 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 100m, which is the straight area.

"Curved straights have also improved a lot, basically there are no flaws. It's just that the speed has not changed much compared with the previous curve. Is he learning the running style of European and American players?" He continues to comment.

The second 100m is the stage with the least amount of time in the entire 400m. Domestic athletes generally speed up the pace of some steps on the first straight, greatly increasing 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 is 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 most likely adjusting the pace to get a higher speed.

Turning a curve into a straight road requires an adjustment. Previously Zhang Guan was weak at this point, but through practice, he is already very familiar with the process of cutting a straight road in a curve. At the same time, he is continuing with 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 is 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 the inside.

"He doesn't run well on this straight road and he 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. At this point, Zhang Guan is still not very skilled with it. When he makes adjustments in the corners, the loss of time is a small matter, mainly affecting the overall rhythm.

The third 100-meters is a threshold for domestic athletes, especially the acceleration of the straight will make the human body into a tired state. At this distance, the human body will enter a state of slight hypoxia, and the speed will appear to decline. At this stage, athletes mainly adjust and accumulate energy to prepare for the final sprint. During this period, many domestic athletes will spend more than 12 seconds.

Many athletes 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 100 meters.

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. The rhythm of the first 200 meters has not changed. It is also the same after entering the second curve. Is this the same kind of running method that Michael Johnson used?" Director Ma was stunned. Then, he immediately 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 you may fall behind the opponent in the first half. In the era of Michael Johnson, this style of running was very popular, and Michael Johnson also conquered the entire world with this style of running. Up to now, many American athletes still use this kind of running method, which is regarded as a mainstream running method for European and American athletes.

Athletes who use this type of running are often explosive. Although their rhythm in the early and middle stages is controlled evenly, when they want to accelerate, they will instantly increase their speed and which will catch the opponents off guard.

"How is it so old? Why did you teach Zhang Guan this running method, which requires very high requirements on the body and requires a perfect distribution of physical strength." Director Ma glanced at something unclearly and then focused on Zhang Guan.

"According to this running method, the first sprint should be started at about 250 meters! So what will Zhang Guan choose next? Is it the sprint? 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 then the time taken for the third hundred meters is almost only 0.3 seconds slower than the second hundred meters.

This sprint will continue until they're about to go straight, and then there will be two changes:

One way of running is to sprint directly until the end, but after 250 meters of high-speed exercise, even if the previous rhythm is used to reduce physical exertion, most athletes cannot maintain a sprint of up to 150 meters, often to till 350 meters there is not much power around 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 buffers than the first method, and it can last longer and longer in the straight sprint later, but the requirements on the body are extremely high because the first sprint of about 250 meters will consume part of the physical strength. The second sprint immediately started after entering the straight, if the physical quality does not meet the requirements, the explosive force will not be able to have an output, and it will not be able to rush at all. At the same time, the 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 to sprint at the end which is the correct way to run! But after all, Zhang Guan's rhythm in the first half is well controlled. If he chooses to enter the straight line for a second sprint, it is not impossible." Director Ma stared at Zhang Guan closely and began to look forward to Zhang Guan's 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 the rhythm.

The same is true for 270 meters.

He was still at the same pace as when he started.

"What's going on? What is Zhang Guan doing? It's almost the end of the straight, why didn't he sprint? Does he have no physical strength? No, although the speed in front of him is not slow, there is no obvious change in rhythm physically, so there must be reserves." Director Ma has been unable to understand what Zhang Guan is going to do, so Director Ma stared at Zhang Guan running straight into the straight.

"Go straight!"

At the same time, Zhang Guan began to accelerate, and the speed was raised in an instant.

"He started sprinting after entering the straight! What the hell is happening! It's too late at the time. Is this some kind of outdated running method that happened decades ago? How do you teach this old thing? You don't teach things that are improving, but instead, teach this outdated running method of the last century? This running method has long been eliminated by the times!" Director Ma began to blame the coach.

But then, he found that the speed of Zhang Guan on the track seemed to be somewhat different. Specifically, it seems to be too fast.

"Why is the sprint speed so fast! Is he 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. Also at this moment, 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, so he needs to run forward without thinking!

At this time, Zhang Guan's physical fitness is still relatively abundant. The uniform rhythm in the front will originally save physical strength. While the Incomplete activation of the sprint is even more natural. It can only consume 50% of sprint skills. The physical energy consumption is much less than an athlete who ran into the last straight under the same conditions.

Then he showed a speed that was not possible in a 400-meter sprint!
