The reason for this feeling.

This is because in the original sprint system, this kind of thing does not happen now. Unless you have a physically distributed type of running method, you may have pushed a lot in front and there will be motivation behind it.

That's reasonable.

But now this.

Su Shen is obviously not.

He rushed forward so quickly and so vigorously, which was completely a typical Jamaican running method. Such running method is a problem and cannot be ignored and avoided...

After 150 meters, the limit of physical strength will be displayed.

In other words, what is your original talent?

Here you will be fully displayed.

The kind that doesn't take off the clothes enough.

It's all skinned.

Even Bolt.

It's not bad either.

But now...

What Su Shen was doing was what they could not imagine.

Why can he continue to make efforts here?

And in this place, it was originally impossible for him to hold on.

Su Shen ran 200 meters so many times before, but no exception was the same.

So Xie Zhengye is a little irritated now.

I followed behind and didn't understand what was going on.

Why is Mr. Su here...

Suddenly the speed drop has decreased.

If so.

Those things I customized before.

Haven’t all the plans that were planned with Yang Yaozhu become useless? They were completely disrupted.

The first thing to do is one thing.

For long-term sprints, fatigue stage control.

Although all trends found in short sprints are also evident in long sprints, due to the length of the race, significant compromises must be made to explain the effects of fatigue. In past cognition, long sprints were defined only as 400 meters or more items, but with a large number of experimental data, fatigue also began to significantly affect the 200 meters item.

Therefore, the 200m race should now be regarded as a medium-length or short-range sprint event. This will not change the overall concept of short-term or long-term sprints, but simply how to view the different phased effects they present.

The term "fatigue" is often defined as the unconscious loss of speed. In modern sports science, it is regarded as an unconscious loss of force output. Since all the mechanical concepts proposed by Suss and Ralph Mann are based on effective forces, the maximum possible velocity value will be generated if performed properly in theory.

Sushen Laboratory has now summarized five points. Regardless of the preferred definition, the causes of fatigue are inherently diverse and complex. The potential reasons why athletes cannot generate productivity include:

1. Energy (ATP) is lacking relative to demand.

2. Metabolites accumulation that hinder muscle contraction.

3. Reduce ATP output through glycolysis and ATP-PC energy system.

4. Inappropriate sprint mechanics.

5. Repeat high-intensity impact.

The first three items are based on physiological modifications and changes, which require years of training and even continuous physical transformation to obtain them. There are many things, and there are almost no means of improvement at the moment.

These athletes on Ersha Island, especially Su Shen, attach great importance to their physical development. Over the years, they have long become one of the specimens among sprinters. Therefore, it is impossible to make breakthrough progress in the first three items in the short term.

Su Shen can complete three times the increase in leg strength in this year's winter training, surpassing the excellent standards he could not meet before. This is already a major breakthrough.

If you want to improve your space, although there is still room for improvement, it is not a matter of a short period of time. It must be based on years.

Therefore, if you really want to make a breakthrough in a short period of time, you must start from the next two points.

This is also the focus of this shot. Is there any possibility of improvement in terms of mechanics?

The answer is of course there is.

Front mechanics is used to do this.

Unlike sprinting, in a 400m race, the body cannot complete the event with the best efforts, which is well known. This forces even elite athletes to compromise on speed and energy consumption. While it can be said that 200m is a sprinting event, anyone who has participated or directed this race will confirm that fatigue is a major factor.

Whether your fatigue resistance is strong or not is determined by the overall 200-meter performance trend.

The energy system that mainly drives the 100m race is the ATP-PC system, which neither consumes oxygen nor produces waste metabolites. Compared with the other two systems, the energy generated by the system is very fast, which makes it very important for sprinting bioenergy. However, the total capacity of the ATP-PC system is very small, even if there are now theories and means to promote it to improve, which changed the fact that it was previously believed that this aspect could not be improved. However, for the 200m race, this energy supply system is still...

Too little.

In short sprints, the glycolysis and oxidation systems make up a large proportion of energy, which may surprise most coaches.

In long sprints, since fatigue is a major factor, the level of power consumption must be effectively adjusted throughout the race. In addition, the economics of power application become more important, as any wasted effort will not only reduce the current level speed, such as in starts and short sprints, but also reduce the energy supply required to generate power later in the race.

According to the experimental data guided by Su Shen, it can be quickly concluded that at the beginning of a long sprint, fatigue begins to require performance compromise. In the non-fatigue state of the game, the speed drops around 8 o'clock. Compared with the short sprint, 200 meters and 400 meters decreased by 16% and 16%, respectively. These results are the first sign that fatigue begins to play a major factor even in the initial part of the 200 meters. Because, at this stage of the game, the athletes are not in a fatigue state, so the reduction in speed is to preserve energy.

This chapter is not over, please click on the next page to continue reading! At the end of the race, no matter the quality of the elite sprinters, as the fatigue begins, the speed will experience an additional drop. Compared with the non-fatigue state, the speed decay of 200 meters is about 10%, and the speed decay of 400 meters is about 15%. What is even more surprising is that compared with the short-distance sprint, the drop of 200 meters is 16%, and the drop of 400 meters is an astonishing 31%.

All of these point to a conclusion: the athlete's ability to produce short sprint speeds is crucial to the success of long sprints. It also emphasizes another observation shown in this example...

Improving fatigue speed is the best way to improve long sprint performance.

Finally, Sushen Laboratory came up with a new inference:

The performance improvements caused by the increase in fatigue speed are more than 50% greater than the gains caused by the increase in non-fatigue speed.

This proposes a new research topic for the 200-meter running, a short- and medium-term project between 100-meter and 400-meter-

The large decline caused by fatigue is a major area of ​​improvement potential in the future.

Now what Su Shen has to do is change in mechanics, using the front-side mechanics system that was just released at the end of last year to make the first wave of impact on this topic on this timeline.

And in the next ten years, Ralph Mann will develop a brand new scientific research data himself:

Compared with the short-distance sprint results, the 200 stride frequency result was 6% reduced when the non-fatigue sprint results, while the 400 data was 14%. In contrast, if the difference in horizontal speed between the short-distance sprint and the 200-meter sprint results were almost the same. What is more surprising is that in the 400-meter race, only the best elite athletes were able to maintain the same distance as the short-distance sprint.

So actually all other athletes can keep a longer distance.

When fatigued, the stride frequency of 200m and 400m dropped by 7% and 14%, respectively. As in the case of non-fatigue, the best athletes maintain their stride length when considering the difference in speed, while the less performing athletes actually increase their length.

Therefore, athletes who can best manage or avoid fatigue can control their speed by focusing on pace at the end of the game.

There is also a surprising conclusion, that you are usually...sprinters who have to rely on additional strides to deal with fatigue are classified as average or poor performance categories.

And in the last century and at the beginning of this century, these were considered mainstream ways to improve performance.

Similar to Zhang Peimeng.

Similar to Su Shen.

Similar to Xie Zhengye.

In fact, they have all used this kind of passive approach that has been recognized by the front side mechanics as a passive approach that will only be taken when the performance is average or poor.

Even trained as the main point.

This is why science in any field needs to be updated and iterated. Because it is very likely that the regulations considered the most reasonable and indestructible in the last century will become something completely overthrown by the next century.

Science has never ended, and the unchanging thing is not called science.

I have been making progress and correcting mistakes and finding laws that are closer to the truth, that is the real science.

Then the most important thing is here.

Sushen Lab's latest conclusion is that for the best 200-meter athletes, stride rate, that is, stride frequency, is the only variable to be changed when fatigue is the main factor in the sprinting event. For lower-level athletes, fatigue becomes an overwhelming need, with both rate and length affected. This leads to the insight that athletes who maintain speed and length in non-fatigue and fatigue states…

The most successful in a long sprint.

Then the final conclusion is-

Only the latest mechanical system can meet this requirement. It is difficult to train to these places in the original mechanical system. This is determined by the basic structure of the original mechanical system, and it is more talented in the backside mechanics.

Even if you want to improve these aspects through training, it is difficult to make this modification if you adopt the Jamaican running method.

Therefore, this is also the reason why Su Shen was unable to train these specific techniques before. He could only start from the first 3 points.

But now.

The time is ripe.

The front mechanics has been pushed out according to the original timeline. The most important thing is that my body is now ready to be prepared to recombinate the new mechanics system.

This is why Jamaican's running method was finally popular all over the world, not only because the running method itself is more in line with the trend and more advanced, but the most important thing is that there is a new mechanical system that matches it with a good take-off runway.

Otherwise, Jamaican running style is too talented, especially the 50 meters behind, which is extremely difficult to improve through training, which is enough to discourage most athletes.

This is the change in productivity and production relations.

New productivity emerges.
