"The lowest point of your body's center of gravity appears at 30% of the running support phase. The end of the back kicking phase is a critical stage when the displacement speed increases, and the vertical speed of the body's center of gravity should gradually level off at the end of the back kicking phase, but you According to the reality of the analysis map, chaos is gradually starting to appear in your place."

"To achieve such a result, our current analysis believes that there is a problem with the order of the muscles supporting the leg. The original order should be: gluteus maximus, rectus femoris, semitendinosus, biceps femoris, and tensor fascia lata. , embryonic anterior muscles. But the order of force exertion of your supporting leg muscles is obviously not right, and this area of ​​yours needs major improvement."

"The second issue is your core data. This is your core data. Our adjusted core data is this group." Randy clicked the mouse and said: "Your total step count should be adjusted to 46.200 now, on average. The step length is adjusted to 2.165, the average cadence is adjusted to 4.687, the average speed is increased to 10M/S, the step length index is adjusted to 1.164s, and the cadence index is adjusted to 8.720."

"If you can do it..."

"What would happen if it were done?" Zhang Pei suddenly asked.

"If you can do it, we estimate that you should be able to run close to 10 seconds, or even hit the ten-second mark."

Zhang Peimeng was shocked when he heard this.

Because of the ten-second mark, this was a result that I could never imagine before, but it is now...a very desired result.

Now that Su Shen and Zhao Haohuan have achieved it one after another, what Zhang Peimeng once thought was unbelievable has now become reality, and he feels that it is no longer impossible at all. This is how people feel that once they feel it is possible, their mentality and desires will immediately change accordingly.

Moreover, he has also seen Randy's ability. This is a great coach recognized by Su Shen. His professional ability has refreshed Zhang Peimeng's sense of coaching. If he says it's okay, then it's probably true.

If he can do it in ten seconds, then his future will be brighter.

It can even surpass the strongest "newcomer" in the country now, a master of work and rest.

Zhang Pei has reached this level, and his goal must have changed. He is no longer competing with Wen Yongyi, but with Lao Yi and Hu Kai who are further ahead. Hu Kai is already old, so Lao Yi will be his third position in the future and his most direct competitor.

Not to mention breaking ten.

Whoever can reach ten seconds first is a huge challenge.

At present, my 100-meter PB is 10.15s, and my work-rest time is 10.09s. Both of them are small wind guns, so they are still missing a level of hard power. Although Lao Yi's talent is terrifying, even the most terrifying talent he has ever seen, his progress has slowed down recently, so he... is still capable of fighting.

As for Zhao Haohuan and Su Shen, they have not broken ten at present, so he will not think too much about this issue.

After coming to Ersha Island for so long, Zhang Peimeng learned this ability to correctly evaluate his own strength and the strength of his opponents.

Find a reasonable target to pursue, this is what you should do now.

Otherwise, change the target to 9.83s or 9.90s, which is really...

There was no motivation to even touch it.

Therefore, after setting his next target, Zhang Peimeng began to translate the pros and cons of himself and Lao Yi into actual numbers. For example, he is more than ten centimeters taller than Lao Yi, which is his advantage. However, he is so much taller than Lao Yi, but he is actually a cadence type athlete. If he competes with Lao Yi in stride index, he will be completely blown away. . Can you believe that when Zhang Peimeng saw that the work-rest stride index was as high as nearly 1.25 for the first time, he couldn't stand it.

Why do you say that?

Just looking at a piece of data, you may not feel anything, but if you compare it, you will understand why Zhang Peimeng can't hold back.

Because Lao Yi is obviously only a little over 1.7 meters tall, but his stride index is pretty good...

Usain Bolt.

Yes, you read that right, and I made a typo. In fact, the pace index between work and rest is comparable to that of Usain Bolt.

Both of them are around 1.25. Think about it, what kind of monster is Bolt. (Oh really)

He is more than twenty centimeters taller than Lao Yi.

With such a big height difference, coupled with Bolt's originally long black legs with golden proportions, and such superior physiological conditions, but the stride index is about the same as work and rest, you should understand why Zhang Peimeng's jaw was almost stunned when he saw this. Lose.

It’s really not our Brother Pei Meng’s fault, it’s just that his opponent is a “pervert”.

What is Zhang Peimeng's stride index? Randy's request to him is to increase it to 1.164, so in fact, he is still far behind 1.164. And even at 1.164, there is still a huge gap between work and rest at 1.25. This is true talent, a physical talent that cannot be solved. It never means that the taller you are, the greater your effective stride is. It is just relative, but there are always exceptions. The great man of work and leisure is one of them.

So here comes a strange imagination.

Lai Yi, who is more than ten centimeters shorter than Zhang Peimeng, uses less stride length throughout the entire race than Zhang Peimeng does now.

Zhang Peimeng needs to get closer to 47 steps, while Lao Yi is now at 46 steps.

This is still a comparison method of playing hooligans regardless of height conditions, but even so, even if you are "playing hooligans", you will still lose completely. At this point, Zhang Peimeng completely understood that although his stride length needed to be improved, he still wanted to compare it with a "natural stride monster" like Lao Yi.

Just stick to the cadence route.

In fact, in the original timeline, Zhang Peimeng suffered from this disadvantage and kept expanding his stride length. As a result, he had no talent in stride length. In the end, not only did his performance not improve but regressed, he also began to get injured. This is a typical example of taking the wrong path. If you take the wrong path and violate your own physiological optimal solution, then it will be a matter of time before you exceed your body's threshold.

"There is also the issue of your running cycle." Randy continued to give Zhang Peimeng a comprehensive analysis: "A cycle in running is composed of a single step, including two foot supports and two soaring periods. The speed of the cadence It depends on the length of the support time and the flight time. Sushen Laboratory research shows: 'The support period and the flight period in fast running are relatively close, making it easy to coordinate the support and flight of the two legs, which is conducive to increasing the cadence and speed'. International The ratio of support time to airborne time for elite athletes during running is about 1:1.2, and you and Lao are both unqualified on this point."

"Especially Lao, your ratio is close to 1:1.340. This is really too bad. You must train well to improve your support time and flight time. Otherwise, your excellent stride talent will be too much for you. It's a waste." Hearing Randy suddenly cue him, Lao Yi immediately touched his head in embarrassment, and said seriously and simply: "I know, I will work hard, and I will definitely not disappoint the coaches' expectations. Yes, and I will live up to Tim’s expectations.”

This scene made everyone happy, and the atmosphere relaxed. Randy continued: "Zhang, your support time and flight time are close to each other, and both are shorter than Lao. It means that your support time during the flight is closer to Lao than Lao." The technical characteristics of the world's top athletes. Improve and improve your cadence in the future, which will be your huge advantage."

"Finally, let's take a look at your last ten games and compare and analyze the angles of each joint during support during running."

Randy switched the ppt to the next page and said: "We all know that the support period of running is divided into the buffer stage, that is, the moment of landing to the vertical moment and the back pedaling stage, that is, the vertical moment to the moment of leaving the ground. The moment of the foot landing is the buffer stage The starting point of the landing, the angle of each joint when landing directly affects the athlete's speed. Research shows that a small landing angle will lead to a longer buffer time when landing, and at the same time cause a greater impact force on the ground, which will invisibly increase It affects the braking of the foot when it touches the ground, affects the continuity of sprinting technical movements, restricts the full exertion of the supporting leg muscle strength to a certain extent, and causes a great loss of horizontal speed."

"Let's compare you and Lao."

"Zhang and Lao's landing angles during the mid-run phase are 69.3 and 65.3 respectively. If Zhang's landing angle is large, you can better shorten the landing buffer time and maintain a greater horizontal speed. If you are Lao, you will be supported during the buffering phase. The angle change range of the leg and knee angle from the moment of landing to the vertical stage is 7.9. In comparison, Zhang's change range is only 5.8. The buffering amplitude of Lao's knee angle is greater than that of Zhang. Therefore, although Lao's landing angle is small, the landing buffering time It is longer, but because the "scratching" movement is not active enough, it is more active in the cushioning and retreat of the supporting leg, which increases the initial length of the agonist muscle of the supporting leg, which is conducive to the development of muscle contraction force and speed in the back pedaling stage. Zhang You's words are as good as Law is just the opposite.”

"Both of you must remember that the vertical support phase is the beginning of the back-pedaling phase. Reasonable support and buffering technology can optimize the effect of the 100-meter athlete's pedaling technique during running. The knee angle of the swinging leg is related to the swinging speed of the swinging leg. The swinging speed passes It reflects the folding degree of the swing leg. The higher the degree of folding, the greater the swing speed. The swing speed of the swing leg has a significant effect on the horizontal displacement speed of the body."

"And your swing knee angle is 3.7 worse than the opening, which will prevent you from swinging your legs better and increasing the degree of folding, so as to fully utilize the contraction force of the hamstrings to extend the hip and bend the knee."

"For Zhang, he should strengthen his stride ability training and improve his stride index. For Lao, he should strengthen his stride ability training and improve his stride index. Shortening the support time and flight time is still a technical training for both Lao and Zhang. direction. At the same time, Law should also increase the proportion of propulsion during the running stage to reduce the gap with the world's outstanding players. During the back-pedaling process, the angle of the back-pedaling angle should be reduced as much as possible, the degree of folding of the swing leg should be increased, and the Swinging speed to optimize pedaling technique." Randy said: "Now you all understand it."

Seeing the two people nodding, Randy turned his attention to Su Shen and said, "Then it's your turn, Xiaotian. Share your unique skills with Zhang here."

Su Shen walked up with a smile, no stage fright at all, he was doing his job.

"This technology is starting in second gear. It is a set of technologies I designed and researched specifically for you. It can make your start and acceleration more powerful, and is more suitable for taking advantage of your cadence." Su Shen said seriously: "As long as you practice this well, you will be one step closer to your 10-second countdown."

"The specific method is..."

In fact, Su Shen had already helped lay out the introduction to this method, and had previously asked Zhang Peimeng to start training in related aspects.

Now that it is launched, it is actually just a matter of course.

At this time, Yuan Guoqiang walked up to Liu Xiang and Sun Haiping, smiled, patted the latter's shoulders, and asked, "How are you doing?"

"I feel like I'm getting used to it."

"I..." Sun Haiping was shocked, because he was also fascinated by what he heard. He never expected that he could be so precise in running. And they are all scientific calculations, not subjective experiences at all.

The key is that he can actually analyze such intensive project improvements for each of these people. It is really something that was impossible to think about before.

But they just did it.

"Are they like this every winter training period?" Sun Haiping finally asked with a "struggle".

"Yes." Yuan Guoqiang said: "Every time there will be a different plan. After all, the physical condition of athletes after each season is very different. If it cannot be modified and adjusted in time, it may cause harm to the future of the athletes. "

"Then...can you really understand such a profound thing?" Sun Haiping had the impression that athletes should just do their own thing.

The rest of the arrangements and planning are all the coach's business.

This is the most traditional "master-apprentice model".

But obviously, it is no longer applicable to modern track and field.

"You can do it all." Yuan Guoqiang said, "You will also be able to do it in the future."

"I hope so." Sun Haiping felt that he was getting older, and he might not be able to keep up if he did this now.

But Yuan Guoqiang's words rekindled his confidence.

"Randy and Ralph Mann are so old. They often take Su Shen's small classes and often ask him questions to improve their studies. We are so much younger than them, how can we still be old?" Yuan Guoqiang said: "As flower growers, we cannot lose to the Waiguo people like this, especially the Waiguo elders."

Half joking and half serious, Yuan Guoqiang asked Liu Xiang again: "What about you, what do you think?"

Although the impact of Liu Xiang's retirement is not small, he is still the perennial number one in domestic track and field, and his opinions and feelings are still very important.

"Five words." Liu Xiang said.

"Oh? Which five words are there?" Yuan Guoqiang asked in a serious tone.

Liu Xiang blurted out: "High, really high."

"I never thought that sprinting could be so meticulous and scientific. I think there are few training bases abroad that can compare with this one."

After a while of silence.

Yuan Guoqiang suddenly burst out with a loud smile and said: "Hahahaha, Xiao Liu, you are really wrong about this."

Yuan Guoqiang didn't know when he talked about Ersha Island with full confidence, and said with stars in his eyes:

"On the level of professionalism and technology."

"Our Ersha Island is said to be second."

"Who dares to say number one now?"

Yuan Guoqiang looked at these talented young people and the increasingly perfect top team with great pride in his confidence:

"Even the best sprint clubs in America."

"These aspects now."

"You can't compare with us."

This was Su Shen's plan at the beginning of last year. At that time, Yuan Guoqiang also thought it was impossible. How could this be possible based on the capabilities of the Zhonghuajia's training base? It was the American Sprint Club with a profound foundation.

But now...

Yuan Guoqiang just wants to say: It smells really good.

In just a few words, all kinds of pride slowly unfolded in front of Liu Xiang and Sun Haiping.

At this point, the two of them fully understood why this Ersha Island has become the holy land of track and field in the country.

Because, everyone here.

Everyone is starting to believe this.

This.

This is the beginning of the foundation formation.

In the past, I always thought about going abroad for training, even at my own expense. People may not tell you the latest and most complete things.

it's good now.

The holy land of athletics.

There is one in the country.

Then...get out of here.

"So, let's all stay and build this place together." Yuan Guoqiang said seriously and sincerely: "Let us witness this training base with our own hands and become the strongest in the world. What do you think?"

"The strongest in the world".

What a loud tone.

But it has to be said.

Both Liu Xiang and Sun Haiping were completely moved by these words.

It completely mobilized the little flame in my heart.

Until a spark.

It can start a prairie fire.
