The Su God of the Reopening of the Sports Arena

Chapter 1963 Reducing the burden on the body! Is the first step to becoming faster

  Can this be solved too?

This isn’t easy, is it?

Randy looked at Su Shen and said, "Your weight is already very large. It may not be easy to break through three times."

"You've gained some weight recently due to activities. Your latest weight should be over 90 kilograms. Based on your weight before the technical transformation, it would be appropriate to reduce it to 89 to 90 kilograms."

"In this case, you need to be able to squat 270 kg. Although sprinters don't need to squat that deep and it's easier to lift weights, it's still not an easy task."

"So you said you want to triple your weight, and you have to triple it by a lot. I find it hard to imagine." Randy said, "You are not the type who is particularly thin. How can you do it? I still say that it is easy to triple your 60 kg body weight physically, but it is too difficult for you to triple your 90 kg body weight."

"No need." Su Shen said softly, "My nerves are already adaptable enough to squat 270 kilograms."

"That's enough to exceed three times."

"How can you exceed three times? You are already over 90 kilograms. Even if you lose weight to 89 or 90 kilograms, 270 kilograms is just three times as much."

"What if I only need a little over 80 kilograms?"

Su Shen's words confused Randy.

"What do you mean? Just over 80 kilograms, how is that possible?"

"You are obviously going for muscle mass. And through your own laboratory research, you can also conclude that Asians are more likely to gain muscle. If you don't gain enough muscle, you're wasting your Asian characteristics and high testosterone." Randy objected immediately after hearing this: "Besides, appropriately gaining muscle is also a future development path. Unless you are an athlete who can run 400 meters or longer, and your running style is closer to speed endurance, otherwise, without exceeding the reasonable upper limit, you should focus on muscle."

For sprinters, there is really no need to pile on weight like crazy. All the weight is for the purpose of achieving specific results.

But judging from Suarez's current physical condition, Randy believes that there is no problem for him to gain 90 kilograms.

And he was close to that level in 2011.

Not only did it not affect my specialty, but it actually led to continuous improvement.

This shows that Su Shen did a good job.

His weight has not reached the upper limit of his influence event.

According to some theories of Randy and Europe and the United States.

That is, without affecting the speciality, you should continue to accumulate muscle mass, which is what you should do. Because only sufficient muscle mass can be converted into sufficient muscle strength and various special strengths.

There is nothing wrong with that.

but……

The human body's growth ceiling is always limited.

And the greater the weight, the greater the relative unit energy consumption. The key is that there is indeed an upper limit to the increase in leg strength.

Want to break.

Reducing weight and increasing leg strength is one approach.

But this is a concept that is difficult to understand in the current American system.

Because it’s in the American system.

Want to own this concept.

That will be 10 years later.

At present, the mainstream is to continue to gain weight without affecting athletic function.

Su Shen's proposal at this time is certainly non-mainstream.

Randy even wondered if he was crazy.

It is really hard to understand why he gave up the strongest muscle-building talent of the yellow race that he had researched, and the strongest testosterone talent of the yellow race.

The key point is that Su Shen has clearly not reached his optimal limit using this set of skills.

The results have been good before.

If you bring this up at this time, people will naturally find it confusing.

"Huntington, you don't understand what I mean." Su Shen said: "I want to reduce my ineffective weight."

“To keep my effective weight as much as possible.”

"What do you mean?" Randy has looked through all the physical training books in the United States, but has never seen such an argument.

And now it is a recognized fact that a person's body muscle and fat growth are holistic, so how can we distinguish them separately?

this point.

It's the limitation of the times.

It's similar to this era. If you talk about front-side mechanics, no one knows what you are talking about.

"I just want to get rid of the muscle formations on my body that are not useful for sprinting."

"Huh?" Randy was stunned. "Isn't this okay?"

“I’ve never heard of that.”

"I haven't heard of it. It's normal." Su Shen grinned and chuckled: "It will be there from now on."

"This……"

Randy understood immediately and asked, "Is this another new thing you have researched?"

"Well, you can say that." Su Shen said: "So far, no one has used this to conduct specific experiments."

I go.

Come again? ? ?

Randy felt a sense of déjà vu when he heard this.

After he came to Ersha Island, he couldn't remember how many times he had heard this.

From the initial shock to now, I am still... shocked.

I was just a little numb from the shock, that's all.

"You mean you're using yourself as a guinea pig again?" Randy touched his forehead with his hand, with a helpless expression: "You know what? If it weren't for you, Su, I would definitely think this is a crazy act."

"But you've succeeded so many times, and now I don't know what to say."

"When a top athlete always uses himself as a first-timer and researcher, I sometimes don't know whether to say he is brave or fearless."

When Su Shen saw Randy's expression, he couldn't help but want to laugh: "No need to be like this, old friend."

"You know my other main job is sports research. I am more or less a professor, and I will soon be studying for a doctorate, so I should have more material for my thesis."

"You...are using yourself for your own thesis. I don't know what to say."

Randy was speechless, but the person in front of him was the young leader in sports science in the world, and it seemed that he did have this responsibility.

Really...

I've never coached an athlete like this.

There has never been such a thing in history.

I have no experience.

"Then tell me what you are going to do." Randy knew that it would be difficult to shake Su Shen's words, but as always, he needed a definite reason.

Reasons that convince him both scientifically and emotionally.

In this way, he can devote himself wholeheartedly to completing Su Shen's exercise plan.

"Yeah." Su Shen seemed to know that Randy would definitely ask, so he continued without hesitation: "Specialized muscles, I absolutely agree with this, but now we have to distinguish which are useful specialized muscles and which are useless specialized muscles." "You continue, Su." Randy said.

"Through so many years of data research, our laboratory has summarized a set of basic models, but we don't have the ability to make a definite inference yet."

"After reaching a certain level, elite athletes can't just do addition, they also have to learn to do subtraction."

"Subtraction?" Randy asked in confusion, "Subtraction of what?"

"Losing non-specialized muscles not only reduces the burden on the body, but also leaves more room for increasing specialized muscles in the future."

"How to do it? What's the reason?" Randy continued to ask. At his level, it was impossible not to ask for clarification.

Need to understand the basics.

It's not like ordinary people who are just criticized a few times.

You want to change a master's mind.

You need a more advanced reason to convince him.

"The first is that it can reduce the burden on the body. A lighter weight means that the gravity and inertia that athletes need to overcome during running are relatively small. In particular, after some excess weight in the upper body is reduced, the overall body mass is reduced. When accelerating and maintaining high-speed running, the burden on the body is reduced, and it is easier to reach a higher speed."

"We all know that, for example, when an athlete loses a few kilograms, the weight they need to push with each step will be reduced accordingly, allowing the leg muscles to produce greater acceleration with the same force output. If converted into vertical force, that means for every 1.5 kilograms of elevation, each step requires 2% more vertical force. If converted to more than steps, the consumption is greater and more difficult to maintain."

"Secondly, it improves movement efficiency. A lighter body can make athletes more flexible and agile. During sprinting, athletes need to swing their arms and legs quickly. A lighter upper body can help reduce the inertia of upper limb swing, making the arm swing movement lighter and more coordinated, thereby better coordinating leg movements and improving overall running efficiency."

"For example, a lighter upper body allows athletes to change direction faster when swinging their arms, reducing energy waste and using more energy to push the body forward. Maintaining more forwardness will not consume too much energy in maintaining forwardness. We should all know now that the output of each technical movement consumes your overall energy. The less overall energy consumption, the more changes you can make at extreme speed. Otherwise, you have already consumed all the energy, you can't do any movements, and you have no energy to do anything you want to do."

"Third, it reduces energy demands during competition. Weight loss means that the body consumes less energy during competition. Sprinting is a high-intensity sport that requires a lot of energy. By losing weight, athletes can maintain high-intensity exercise for a longer time with the same energy reserves, or reduce energy consumption at the same exercise intensity, thereby better maintaining physical strength and speed, and performing better in the later stages of the game."

"Take a 100-meter sprint as an example. A lighter athlete may use 5% to 10% less energy than a heavier athlete during the race, which could be the difference between winning and losing in a competitive race."

"Fourth, it improves energy utilization efficiency. After losing weight, the body's energy utilization efficiency will also improve. The body does not need to spend too much energy to move heavier parts of the body. Instead, it can focus more energy on pushing the body forward and maintaining high-speed running. This allows athletes to use limited energy reserves more effectively during competitions and perform at their best."

"Fifth, from a biomechanical analysis, the moment of inertia is a physical quantity that describes the rotational inertia of an object around an axis. For sprinters, the mass distribution of the upper body will affect the overall moment of inertia. When the athlete reduces the weight of the upper body, the body's moment of inertia decreases. According to the moment of inertia formula, where represents the moment of inertia, represents the mass, and represents the distance to the axis of rotation, a reduction in mass will directly lead to a reduction in the moment of inertia, which means it can also reduce the moment of inertia."

"For example, the initial mass of my upper body is , the distance from the center of gravity to the longitudinal axis of the body is , and the moment of inertia is . By reducing weight, the mass of the upper body is reduced, and the new moment of inertia is significantly less than . The smaller moment of inertia makes it easier for athletes to change their body posture and direction during running, improves the flexibility and coordination of movements, and thus helps to increase speed."

"Sixth, reduce the burden of ground reaction force. During sprinting, the athlete's feet will generate ground reaction force when they come into contact with the ground. According to Newton's third law, the magnitude of this force is equal to the force applied by the athlete to the ground. The greater the weight, the greater the ground reaction force, which puts greater pressure on the athlete's muscles, bones and joints."

"Relevant research in our laboratory shows that for every 1 kg of body weight added, the ground reaction force increases by about 10N. If a sprinter successfully loses 5 kg of upper body weight before a competition, the ground reaction force he or she will bear with each step during running will be reduced by about 50N. This not only reduces the burden on muscles and joints and reduces the risk of injury, but also allows athletes to accelerate and maintain high-speed running more easily."

"Seventh, from the perspective of energy metabolism, it can also improve the power-to-weight ratio. The power-to-weight ratio is an important indicator to measure the physical fitness level of athletes. It indicates the power output per unit weight. In sprinting, the higher the power-to-weight ratio, the more energy the athlete can output per unit time, and the faster the speed."

“Power to weight ratio = power ÷ weight. If a sprinter’s maximum power output is P and his initial weight is m, then his initial power to weight ratio is P/m. By losing weight, his weight becomes m (m.”

Randy:…

You're kidding me, right?

Say you came for a cursory study.

As a result, you gave me such a detailed analysis report.

"Wait wait wait, why haven't I heard of what you said before?"

Randy began to doubt whether he was a master-level track and field coach.

"It's normal that you haven't heard of it, Huntington." Su Shen said with a hint of confidence: "It's enough that you have heard of it now."

"And I have a feeling that this theory will soon become popular in the global sprinting community in the next 10 years."

"I have only mentioned a part of it. There are many more, such as optimizing arm swing, enhancing leg burst, optimizing energy reserves, reducing inertia, etc." Su Shen said: "These are all advantages."

"With so many advantages, I even doubt whether it is a complete set of theories. I need time to absorb and digest them. Please print these things out for me, Su." Randy felt that after coming to Ersha Island, he was not here to be a coach. Sometimes, it was more like coming here for further study and learning.

You are right, it is about further study and learning.

He feels that he can learn new things in every winter training.

Everyone can improve themselves.

These things are the key.

There is no need to learn outside.

This unique feeling.

This makes his thirst for knowledge still exceptionally high even though he is old.

"Of course, the premise of all this."

"It all depends on whether you have a strong muscle mass foundation. Otherwise, if there is not enough absorption, you don't have to talk about this problem. So this program is originally for professional athletes who are mature and have trained for many years."

What Su Shen meant by this sentence is——

If your muscle mass is not up to standard.

You shouldn't learn this.

Don't use this as an excuse.

The way to do it honestly is to gain muscle, and the way to do it honestly is to gain weight.

Only those with this level of professional ability are qualified to say this.

"And it also depends on whether I am losing non-specific muscle instead of losing useful parts."

"This requires precise testing before proceeding."

"Otherwise, you will lose all the muscles you have worked so hard to build, and that would be a huge loss."

"Then how do we judge and define this? There is no precedent or experience." Randy just finished speaking and looked at Su Shen's relaxed expression and said, "Well, it seems that I asked in vain."

"You must have been prepared to say that."

"Of course." Su Shen nodded. He had done muscle analysis in these aspects in his previous life, and the analysis instruments for muscle biomechanics had also been built in advance.

Just for now.

At a younger age.

It can be optimized away.

It’s not like in my previous life where I waited until I was almost 32 in Tokyo to start getting involved in this matter.

"So how much do you plan to lose? How much do you plan to maintain?" Randy asked.

"It depends on the situation. Initially, I think it will be 85kg. It depends on the situation."

"If it's 85kg, then triple leg strength doesn't really require 270kg..."

As soon as Randy finished speaking, Su Shen said, "It still needs to be 270kg."

“That’s only 3.17 times.”

“My goal is to get it up to around 3.2.”

“It would be best if we could break 3.2 times.”

Randy listened and looked at the young man who had just set the 100-meter Olympic record and Asia's first 100-meter gold medal.

Just feel him.

That youthful vigor.

vigorous.

Scary.
