"Everything is ready." Su Shen said: "We don't have to fight hard this time. Just relax and don't be hurt."

"No problem." Hu Kai and others nodded in response.

There is really no problem. After 2 months of training, the overall tacit understanding and level of relay are compared to Athens, I can only say...

120% has gone to a higher level.

Not to mention that everyone has enhanced in all aspects. To be honest, this relay test is highly anticipated.

Randy and the others set up high-speed cameras and analysis equipment, then waved to indicate that they could start.

This is a professional, compound team that has done a lot of work that has not been done before or has not done so meticulously.

Seeing Yuan Guoqiang so confident, Yu Weili was also aroused of curiosity and stared at the track, looking forward to it.

On the track, Yang Yaozhu, the first player, Hu Kai, the third player, Su Shen, and the fourth player, Zhao Haohuan.

This is the strongest time to be shipped out right now.

"Everyone takes your place."

"preparation."

Bang ———————————————

Yang Yaozhu took the baton in the first step, quietly stepped on the starting device in a squat style, lifted her hips and started.

His method of holding the stick has been completely fixed and has adopted a new model, no longer the kind of way he used to take whatever he wanted.

At each step of handover, it is clear where the next rod will be held at the baton.

The gunshot starts.

Zhang Peimeng was paying attention to the first ball on the sidelines because he knew that if he could replace him in the future, he would definitely be the first ball and the second ball. As for why it was not behind, it was because...

Now all fools know that in China, no one can shake the status of Zhao Haohuan and Su Shenhou.

Unless they are injured, no one else has a chance.

Because Zhang Peimeng was the first player in the World Youth Championship, he also paid extra attention to the first player.

He wants to take over Yang Yaozhu's position in the future.

The first stick, which is Yang Yaozhu's stick, should have been vacated from the four sticks at the beginning. Zhang Peimeng's goal is now very powerful. In this environment, he has to abandon the previous "high-mindedness and low-know" situation, and everything starts from reality.

There are also many members of the "Su Shen Group" who have the same goal as him.

Almost everyone looked at the first shot, and they felt the hidden expectations in their hearts.

Yang Yaozhu's start is relatively smooth, but he is still not the top. He is the back-range stream, and he really cannot reach the top-range. But it doesn't matter, because the distance of the first stick is relatively long, which is greater than 100 meters, so there is still actual room for the back-range burst.

Zhang Peimeng looked at him and guessed that his first advantage compared to Yang Yaozhu was.

Yang Yaozhu kicked her feet out. Although her technical movements were still "traditional", she did it very solidly and had a strong talent. She just started to rise in the acceleration zone in one step. There was not enough time to modify this. The time was too short, so she could only do something that could be improved as much as possible.

After reaching the acceleration zone, Yang Yaozhu's strength gradually showed up. After the speed was added up, his strong range ability was the first in China. Although the strongest range of 100 meters was taken away by Zhao Haohuan,... 200 meters, he was still the strongest range.

Hu Kai has never suppressed him.

With powerful rear-range acceleration and new circumferential swing arm technology, his performance on the curve is more stable. At least even Hu Kai can't help but say... he ran well.

Almost no flaws.

Bang, bang, bang, bang, bang.

A few dozen meters behind, you can see that Yang Yaozhu's speed has completely improved. It is different from the future type, so he has not lost speed at all.

Even because of his good endurance, he can increase the fault tolerance rate, so that even if Hukai gets up early, he can have the strength to catch up and hand over the baton smoothly. This is also the key to arranging him to the first baton, which is to avoid problems and immediately hit the morale of the army.

The key point is that Yang Yaozhu and the other four relay players have been the main event in the past few months.

Handover method.

Especially the first and second rods, they all changed from vertical rods to down-pressure.

This is to unify it with the later one, because Su Shen and Zhao Haohuan also used this technical action, which is for unity. Moreover, although the downward pressure type is not as good as the upward pressure type's transmission time (0.48 -0.08) in the rod transfer time (0.46 -0.06), the time through the relay zone is shorter and the start is faster. Even the air running training proves that the upward pressure type is shorter, so why should you choose the downward pressure type?...

Stablize.

Moreover, from a physiological perspective, it also has advantages. For example, the optimal physiological angle of the upper-pick type is 40~45 degrees, and the maximum is not more than 50 degrees. The optimal physiological interception angle of the lower-pressure type is 50~60 degrees. Therefore, from the physiological perspective and muscle physiological characteristics alone, this is an advantage and disadvantage that cannot be modified and avoided. The lower-pressure type is easier to obtain the advantage of distance between transfers and transfers.

For example, Carl proposed in 1992 that the use of a downward-pressed handover bar can shorten each time by 1.0~1.4M. This statement was confirmed and certified by Japan's relevant experts Sawamura in 2004. In addition, the height of the downward-pressed hand is in the best position in the human eye line-of-view range, which makes it easier to hand over the baton and reduce the rate of error. However, the disadvantage is that this method makes the body balance easily unbalanced during high-speed movement, resulting in poor acceleration.

In addition, Sawamura also proposed the "Seven Deadly Sins" of the downward style, creating public opinion propaganda for Japan's "Yuan-style improvement and upward style".

These "seven deadly sins" are as follows-

First, the downward pressing style is not as smooth and natural as the upward lifting style extending the arms backward, and is not easy to master.

Second, while the athlete is extruding his arms back when handing over the baton, it is easy to cause the body to lean forward, resulting in the acceleration start after receiving the baton.

Third, while handing over the baton, because the palm is facing upward and the five fingers are spread out, the movement is not easy to master during movement.

Fourth, once the passer-block player straightens his arms, it will also have an impact on his speed.

Fifth, the athlete's distance is higher and it is not easy to complete perfectly.

Sixth, the baton player is prone to shaking up and down during running due to his straight arms. If the muscles are fixed, it will affect the acceleration of the running due to unaccustomedness.

Seventh, the acceleration of the bat-taker athlete in the relay zone is limited and a certain degree of running speed is required.

But in fact...

These are all taken for granted. Not to mention that the downward trend will be easier to transition to the emerging technology of the advancement, even if it is not a transition, some statements are deliberately exaggerated to promote the promotion of "the best choice for Japanese-style improvement".

Just say a few, for example, he said, "The downward pressure is not as smooth and natural as the upper-pull-up-pull-out-and-stretching arm, and is not easy to master." In fact, if you are familiar with the training, it will naturally be smooth and natural. Athletes do this. As long as they can improve their grades, even if they violate physiological instincts, they may have trained it for you to be familiar with it. Besides, he only talked about the shortcomings of "not fluent", "unnatural" and "not easy to master", but did not say how much benefits it would bring once "mastered", "smooth" and "natural".

Secondly, the "downward type" is easy to distract energy, just like the "upward type" is not distracted.

In fact, not to mention that the handover batons need to be dispersed, and from the perspective of the field of view, the "downward type" is more stable. Otherwise, the "upward-pull type" will not be so easy to fall off the rod.

The sixth point is the same, "because of not getting used to it, it will affect the acceleration of running", so... Isn't it good to be "having used to it".

These are also problems that can be modified and overcome through a lot of training. The biggest problem with the "upward-pull style" is that the physiological angle can never be stable and shortened. In fact, these two things are just one, because the longer the distance of the handover baton, the higher your error rate will naturally be.

Furthermore, after more than ten or twenty years, these problems have been found to be overcome and improved.

For example, the shaking problem and restricted acceleration running were all analyzed and solved by later experts.

Therefore, what you have to say, the "downward-pressure baton technology" that Su Shen now promotes in the team is actually not the "downward-pressure baton technology" commonly used by everyone in this era. It is a "nearly perfect version" that he has improved, or has improved by countless scientific researchers and coaches.

In this way, even if Japan's "Japanese-style improvement and top-notch" is perfectly used, it may not necessarily gain any advantage.

Not to mention the current "Japanese-style improvement and top-notch" approach, it is actually far from the peak of technical transformation.

This is the thrill of science.

In addition, it is more suitable for technological updates in the future, and Su Shen’s ambitions for relay projects will be revealed at that time.

Obviously, Yu Weili is also a scholar, especially paying close attention to technological changes and research in neighboring countries.

So I naturally saw the statement of Sawamura's "Seven Deadly Sins of the Underpressure Handover Technology".

Therefore, seeing this and seeing that the relay team of the Zanhua Family were all replaced with "downward pressure", Yu Weili was still a little worried at first, but soon he was instantly attracted by Yang Yaozhu's handover process to Hukai...

"This, this is..."

Seeing Yang Yaozhu giving this stick, he didn't even encounter any of the "seven deadly sins" that Sawamura said.

He was also a little surprised.

After all, he was also a national athlete before, but an insider turned into an administrative officer, so he immediately captured the key change point.

"Yes, Lao Yu, Xiaotian and his team have completely solved the 'seven deadly sins' of downward pressure." Yuan Guoqiang proudly patted his cross-circling arms with his fingers: "In other words, our version is a truly perfect downward pressure without shortcomings."

"There are no shortcomings."

Yu Weili felt that his knowledge system was once again seriously challenged by the "Su Shen System".
