Chapter 1956: Reducing the burden on the body! This is the first step to becoming faster
Can this be solved?
This isn't easy, is it?
Randy looked at Su Shen and said: "You are already very heavy. It may not be easy to break through three times."
"Some weight has increased due to recent activities. The latest weight should be more than 90 kilograms. Based on your weight before the technical transformation, it is appropriate to reduce to 89~90 kilograms."
"In this case, you need to squat 270 kilograms. Although sprinters don't need to squat that deep and it is easier to lift the weight, it is not an easy task."
"So you said you want to break through three times, and you have to break through a lot more. It's hard for me to imagine." Randy said: "You are not the type who is particularly thin, how do you do it? I still said the same thing, 60
Triple the weight in kilograms is easy to achieve physically, but it is too difficult for you to triple the weight of 90 kilograms."
"No need." Su Shen said softly: "My neural adaptability is enough for squatting at 270 kilograms."
"That's enough for more than three times."
"Why is it more than three times? You are already over 90 kilograms now. Even if you lose fat to 89 or 90 kilograms, 270 kilograms is just three times."
“What if I only need a little over 80kg?”
Su Shen's words made Randy confused.
"What do you mean? Over 80 kilograms, how is that possible?"
"You are obviously on the muscle mass route, and through your own laboratory research, you can also conclude that Asians are more likely to gain muscle. If you don't build enough muscle, you will be wasting your Asian characteristics.
And the attribute of high testosterone." Randy objected immediately after hearing this: "Furthermore, increasing muscle appropriately is originally a development route in the future, unless you are the kind of person who can race 400 meters or longer.
The running style of athletes who come down is closer to speed endurance. Otherwise, you should do what you should do to your muscles without exceeding the reasonable upper limit."
For sprinters, there is indeed no need to pile up crazy weight. All the weight is for special performance.
But judging from Su Shen's current physical condition, Randy thinks there is no problem for him to increase to 90 kilograms.
And he was already close to this level in 2011.
Not only has it not affected my specialization, but it has continued to improve.
This shows that Su Shen has done a good job.
His weight has not reached the upper limit of his ability to affect his special event.
According to Randy and some European and American theories.
It is to continuously accumulate your muscle mass without affecting your special event. This is what you should do. Because only enough muscle mass can be converted into sufficient muscle strength and various special strength.
This is no problem.
but……
The human body's growth limit is always limited.
And the greater the weight, the greater the relative energy consumption per unit. The key is that there is indeed an upper limit to the increase in leg strength.
Want to break.
Losing weight and increasing leg strength is a good idea.
But this is a concept that is difficult to understand in the current American system.
Because in the American system.
Want to have this concept.
That will be 10 years from now.
At present, it is still the mainstream to continue to gain weight without affecting sports functions.
For Su Shen to bring it up at this time is of course nothing short of non-mainstream.
Randy may even think he is crazy.
It is really incomprehensible to give up the strongest muscle building talent of yellow people that he has researched himself, and to give up the strongest testosterone talent of yellow people.
The key is that Su Shen clearly has not reached the optimal limit with this set.
The previous results have been very good.
It will naturally be confusing if you bring it up at this time.
"Huntington, you don't understand what I mean." Su Shen said, "I want to reduce my ineffective weight."
"Keeping my effective weight as low as possible."
"What do you mean?" Randy has looked through American physical training books and has never seen such an argument.
Moreover, it is now a recognized fact that a person's body muscle and fat growth are both holistic. How can there be any reason to distinguish them separately?
This point.
It’s just the limitations of the times.
Similar to this era, if you talk about front side mechanics, no one will know what you are talking about.
"That is, I want to get rid of the muscle shape in my body that is useless for my sprinting."
"Huh?" Randy said blankly: "Isn't this possible?"
"I've never heard of this."
"I've never heard of it, it's normal." Su Shen grinned and chuckled: "It will happen from now on."
"this……"
Randy understood immediately and asked: "You mean this is something new you have researched?"
"Well, you can say that." Su Shen said: "So far, no one has used this to conduct specific experiments."
I'll go.
Come again???
Randy felt familiar when he heard this.
After he came to Ersha Island, he couldn't remember how many times he heard this.
From the initial shock to now, I am still... shocked.
I was just a little numb from shock.
"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 have thought this was crazy.
behavior.”
"But you have succeeded too many times, and now I don't know what to say."
"A top athlete always uses himself to make his first attempts and research. Sometimes I don't know whether I should say you are brave or fearless."
Seeing Randy's appearance, Su Shen couldn't help but want to laugh: "There's no need for such an old man."
"You also know that my main job is to do sports research. I am more or less a professor. I will soon be studying for a Ph.D., so I will give myself some thesis materials."
"You...researched it yourself for your own thesis, and I don't know what to say."
Randy was really speechless, but the man in front of him is currently the young leader of sports science in the world, and it seems that he also has this responsibility.
Really...
I have never coached athletes like this.
Never before in history.

"Then tell me first what you are going to do." Randy knew that it would be difficult for him to shake what Su Shen had said, but as always, he needed a definite reason.
Reasons that could convince him both scientifically and emotionally.
Only in this way can he cooperate wholeheartedly with Su Shen's exercise plan.
"Well." Su Shen seemed to know that Randy would definitely ask, and continued without hesitation: "Specialized muscles, I absolutely agree with this, but now we have to distinguish which are useful specialized muscles and which are
It’s a useless specialized muscle.”
"Go on, Sue," Randy said.
"Through so many years of data research, our laboratory has summarized a set of basic models, but we don't yet have the strength to make an exact inference."
"After reaching a certain level, elite athletes can't just do addition, they must also learn to do subtraction."
"Doing subtraction?" Randy asked confused: "What subtraction?"
"Reducing non-specialized muscles not only reduces the burden on the body, but also leaves more room to increase specialized muscles in the future."
"How to do it? What's the reason?" Randy continued to ask. At his level, it is impossible not to ask clearly.
Need to understand the basics.
It's not like ordinary people, just being spoken to a few words is enough.
You want to change a master's mind.
You will 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 the athlete's body needs to overcome during running is relatively small. Especially after some excess weight in the upper body is reduced, the overall body mass is reduced, and during acceleration
When running at high speeds, the burden on the body is reduced and it is easier to reach higher speeds."
"We all know that, for example, when an athlete's weight is reduced by a few kilograms, the weight required to push each step will be reduced accordingly, allowing the leg muscles to produce greater acceleration under the same force output. If converted into vertical force
, that is, for every 1.5 kilogram raised, each step requires 2% more vertical force consumption, which translates into more than 40 steps, and the consumption is even greater, making it more difficult to maintain."
"Secondly, it improves movement efficiency. A lighter body can make athletes' movements 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 the upper limb swings.
, making the arm swing movements more brisk and coordinated, thereby better matching the leg movements and improving overall running efficiency.”
"For example, a lighter upper body can allow athletes to change direction faster when swinging their arms, reduce the waste of energy, and use more energy to push the body forward. Maintaining more forwardness will not cause the problem of maintaining direction.
Going forward consumes too much energy. We should all know by now that the output of every technical action consumes your overall energy. The less the overall energy consumption, the more changes you can make at the ultimate speed.
The more you have. Otherwise, you will have exhausted all your energy, you will not be able to do anything, and you will be powerless to do anything you want to do.”
"Third, reducing the energy demand during the competition. Weight loss means that the body consumes relatively less energy during the competition. Sprinting is a high-intensity sport with very large energy requirements. By reducing weight, athletes can perform at the same time
Maintain high-intensity exercise for a longer period of time with energy reserves, or reduce energy consumption at the same exercise intensity, so as to better maintain physical strength and speed, and achieve better performance in the later stages of the game."
"Take a 100-meter sprint race as an example. A lighter athlete may consume 5%-10% less energy during the race than a heavier athlete. This may become the key to victory or defeat in fierce competition.
factor."
"Fourth, improve energy utilization efficiency. After losing weight, the body's energy utilization efficiency will also be improved. The body does not need to spend too much energy to move heavier body parts, but can focus more energy on
Propelling the body forward and maintaining high-speed running. This allows athletes to use limited energy reserves more effectively during competition and perform at their best."
"Fifth, from the 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 rotational inertia formula, which represents the rotational inertia, represents the mass, and represents the distance to the rotation axis. The reduction of the mass will directly lead to the reduction of the rotational inertia, which means that it can also reduce the rotational 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. Through weight loss, the mass of the upper body is reduced. At this time, the new moment of inertia is significantly less than. The smaller moment of inertia makes the athlete run
During the process, it is easier to change the posture and direction of the body, improving the flexibility and coordination of movements, thereby helping to increase speed."
"Sixth, reduce the burden of ground reaction force. During sprinting, when the athlete's feet contact the ground, a ground reaction force will be generated. According to Newton's third law, the magnitude of this force is equal to the athlete's force on the ground. The greater the weight,
The greater the ground reaction force, the greater the stress on the athlete's muscles, bones and joints."
"According to relevant research in our laboratory, for every 1 kilogram of weight increase, the ground reaction force will increase by about 10N. If a sprinter successfully loses 5 kilograms of upper body weight before a competition, then during the running process, the ground reaction force will be increased by about 10N.
The ground reaction force 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."

The power-to-weight ratio is an important indicator of an athlete's physical fitness level. It represents the power output per unit body 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 ÷ body weight. If the maximum power output of a sprinter is P and the initial weight is m?, then the initial power-to-weight ratio is P/m?. Through weight loss, the weight becomes m? (m?
..."
Randy:…
Are you playing with me?
Say you came here for a cursory research.
As a result, you gave me such a detailed analysis report.
"Wait a minute, why haven't I heard what you said before?"
Randy almost doubted whether he was a master-level track and field coach.
"I haven't heard it before. It's normal, Huntington." Su Shen said with a touch of confidence: "You can just listen to it now."
"And I have a hunch that this theory will soon become popular in the global sprint community in the next 10 years."
"I've only talked about part of it here. There are many more, such as optimizing arm swing, enhancing leg explosion, optimizing energy reserves, reducing inertia, etc." Su Shen said: "These are all advantages."
"With so many advantages, I doubt it is a complete set of theories. I need time to absorb and digest them. Please print these things and give them to me, Su." Randy felt that he would not be a coach after coming to Ersha Island.
, sometimes it’s more like coming here to further study and learn.
That’s right, it’s all about furthering and learning.
He feels that he can learn something new every winter training session.
can improve themselves.
The key is these things.
There is no need to learn from outside.
This unique feeling.
His thirst for knowledge is still extremely high even at his age.
"Of course the premise of all this."
"It's all based on the fact that you have a strong muscle mass foundation. Otherwise, there won't even be enough absorption, and you don't have to talk about this problem. So this set of plans was originally designed for professionals who are mature and have trained for many years.
Used by sexual athletes.”
What Su Shen means by this sentence is——
If your muscle mass is not up to standard.
You should not learn this.
Don't use this as an excuse.
It's all about building muscle, it's all about losing weight.
Only those who have reached this level of professional ability are qualified to say this.
"And it also has to be based on the fact that I am losing non-specific muscles instead of losing useful parts."
"This requires precise testing before proceeding."
"Otherwise, all the muscles you have worked so hard to build will be gone, and that will be a big loss."
"Then how to judge and define this? There is no precedent or experience." As soon as Randy finished speaking, he looked at Su Shen's relaxed expression and said: "Okay, it seems that I asked in vain."
"You must have been ready to speak."
"Of course." Su Shen nodded. He had already done muscle analysis in these aspects in his previous life, and the analysis equipment for muscle biomechanics was also built in advance.
Just for now.
At a younger age.
It can be optimized away.
It’s not like in my previous life that I waited until I was almost 32 years old in Tokyo before I started to get involved with this matter.
"So how much are you going to lose? How much are you going to keep?" Randy asked.
"It depends on the situation. The initial estimate is 85kg. It depends on the situation."
"If it's 85kg, then 270kg is really not needed for three times the leg strength..."
As soon as Randy finished speaking, Su Shen said: "It still needs 270kg."
"This is only 3.17 times."
"My goal is to improve to around 3.2."
"It would be better to break 3.2 times."
Randy listened and looked at this young man who had just won the 100-meter Olympic record and Asia's first 100-meter gold medal.
