Chapter 2070: Calling upon the power of the mountain god! It is important to be proactive in doing anything.

High altitude training is a topic that is being studied more and more in depth in modern times.

First, at high altitudes, the air density is lower, which reduces the feeling of air resistance faced by sprinters when running at high speeds. Since speed is a key factor in sprinting events, the reduction in air resistance may have a positive impact on the performance of sprinters.

Secondly, the maximum oxygen uptake and lactate threshold will be reduced in high altitude areas, which means that when performing the same exercise intensity in high altitude areas, the body will experience a higher sense of exercise load. For anaerobic exercise such as sprinting, which is mainly based on phosphocreatine metabolism, this change has basically no effect, but for long-distance running, which is mainly based on aerobic metabolism, the results will be negatively affected and the performance will be significantly reduced.

So short-distance running is very suitable, but long-distance running is not.

High-altitude training can then increase the amount of hemoglobin in the blood, thereby improving the efficiency of oxygen transport during exercise. This adaptation may be beneficial for sprinters because sprinting mainly relies on anaerobic metabolism, and the increase in hemoglobin can improve the ability of anaerobic metabolism.

But having mentioned so many advantages, there must be disadvantages as well.

In the past, we did long-term plateau training, but this had the opposite effect.

This is because as athletes adapt to the plateau, their hemoglobin concentration, blood volume, and buffering capacity will increase, and their skeletal muscle structure and biochemical properties will improve. Adaptation to the plateau environment can reduce cardiopulmonary discomfort caused by chronic hypoxia.

However…altitude training does not increase VO.

The effects of altitude training, such as increased blood cell density, rightward shift of the oxygenated hemoglobin dissociation curve, increased lung gas diffusion capacity, etc., may be offset by other negative effects.

Such as decreased blood flow to the chest and surrounding tissues, decreased muscle mass, decreased oxidase activity, etc.

When athletes move from a plateau to a plain, the benefits of altitude training will be offset by reduced plasma volume, slower hematopoiesis, accelerated hemolysis, suppressed immune function, increased tissue damage due to oxidative stress, increased glycogen consumption and increased workload of respiratory muscles.

Long-term exposure to high altitudes can cause skeletal muscle atrophy, especially at higher altitudes. Continuous exposure to hypoxia can reduce muscle cross-sectional area by 10%-22%.

Therefore, it is not advisable to train here for a long time. You need to plan and coordinate your time well.

Then use the lactic acid paradox to improve your body's functions and thus improve your performance.

Because as altitude increases, blood lactate concentrations decrease. Although the mechanism is still under debate, it is certain that athletes who have adapted to the altitude environment have reduced lactate production during maximal intensity exercise.

Note that it is the maximal intensity exercise above that reduces lactate production rather than speeds up lactate clearance.

This is a new achievement of modern science.

This is because when energy supply is met, the ATP energy supply ratio increases and rapid glycolysis decreases.

But the effects generally don't last more than six weeks.

If you are in a low oxygen environment for a long time, more than six weeks, this phenomenon will disappear.

Therefore, Su Shen now needs to develop a more advanced improvement mechanism, and based on the above principles, do a good job of "living high and practicing low".

This training method requires athletes to live in high altitude areas for several hours a day and move to low altitudes only during training.

But this is too troublesome, because it is not an easy task to change the terrain from high to low.

The distances are usually long and large.

So, is there any solution?
Of course there are.

It relies on the increasingly mature sports technology at this stage.

For example, what Su Shen is doing now is the new product launched by his Su Shen Laboratory——

A device that simulates low oxygen levels at high altitudes.

and high-oxygen devices that simulate low altitudes on the plateau.

In doing so, altitude acclimatization can increase the amount of hemoglobin produced, heme, and hemopoietin, which helps athletes train at higher intensities in plains or low altitudes.

Living at a plateau at an altitude of 2200-2500m helps increase hemoglobin production.

At an altitude of around 3100m, other parameters except blood can be most effectively improved.

The optimal period to accelerate hemoglobin production is about 4 weeks, and training of less than 3 weeks can improve exercise economy and acid-base buffering capacity.

Staying at an altitude of 2500m for 20-22h/d is enough to improve athletic performance and promote hemoglobin production. The lower limit of the hemoglobin production effect is 12h/d.

Su Shen has arranged these data very clearly.

Especially when he decided to do it this year, the first physical stimulation was actually the most responsive and intense.

He strictly follows the scientific process to carry out the "live high and train low" model. This training started in Ersha Island this year. He uses high technology and simply executes it repeatedly. Then he waits for the body indicators to rebound before continuing with the second adaptation.

The benefit of having precise data to guide you is that you can highlight both the best and worst results.

Try to get as much benefit as possible and minimize the harm.

At this point in time, most people only know this concept.

These are clear data indicators.

It will take a few more years before the laboratories can verify it bit by bit.

It’s different here with Su Shen.

He always came up with the answer directly and then intentionally guided the geniuses in the laboratory to work in this direction.

If you avoid taking the wrong path and trial and error, the road ahead will naturally be smooth.

Do you think that Su Shen said this year that he would let all athletes take advantage of others’ low points and kill them when they are sick?

Are you kidding?
That's more than just an improvement in training methods.

There must also be progress in training technology.

It's not just about running shoes and running tracks.

There are also various black technology products guided by the accuracy of scientific indicators and scientific data.

Accurate data is the most difficult part.

Although there are studies in this area at present, for example, in Europe and the United States, there are also "Altitude training for elite endurance athletes: A review for the travel medicine practitioner", "Review of Athletic Guidelines for High-Altitude Training and Acclimatization", "Simulated Altitude Training and Sport Performance: Protocols and Physiological Effects", etc.

The translation is "Altitude Training for Elite Endurance Athletes: A Review for Medical Practitioners", "A Review of Guidelines for Athletes in Altitude Training and Adaptation", "Simulated Altitude Training and Athletic Performance: Protocols and Physiological Effects"...

Unfortunately, they are still in the exploratory stage and have not determined any precise data like Su Shen.

Therefore, although the research is very cutting-edge, there are only a few people who dare to start and do it and maximize the benefits, with almost no disadvantages...

Except for Su Shen’s current team.

None of them can be done.

Even if many people do this, due to the lack of precise scientific theories and scientific data support, some uncontrollable negative effects often occur.

And these aspects are on Su Shen's side.

Basically it will not appear.

This also means that Ersha Island will hardly appear.

Only now can they truly maximize the use of this plateau training.

At least within the next 50 years.

No new arguments can surpass them.

In addition, last year was the Olympics, and this year most people's bodies were in a state of fatigue and rest. The flower-growing family was just the opposite. Not only did everyone recover from fatigue through black technology training, they maintained their condition and even achieved greater intensity. At the same time, they also used the "perfect plateau training method" promoted by the team led by Su Shen, and used the black technology equipment launched by Su Shen's laboratory that can complement whether you are on the plains or on the plateau.

What do you think.

I'm afraid it will be difficult if I'm not in good shape today.

It may even be the year when the gap between us and world-class athletes is smallest.

This is definitely not nonsense.

Of course, in addition to these basic skills, which Su Shen has achieved almost perfection, he also has to work on advanced projects.

The first is the LSD training method, also known as low-intensity continuous training, which can challenge the body's aerobic metabolism in a plateau environment. Arrange low-intensity continuous LSD training, such as running at an intensity that can last for 30-60 minutes, and control the speed to a level that can be easily talked. This helps to improve cardiopulmonary function, adapt to the low-oxygen environment of the plateau, and increase oxygen intake and transportation efficiency. Next, use the air resistance formula to accurately calculate that in a plateau environment, athletes can achieve a higher speed than in plains under the same force.

This is because the air pressure in plateau areas is lower and the air density is relatively small. According to the principles of fluid mechanics, the resistance an object encounters when moving in a fluid is proportional to the density of the fluid. When sprinters are running, the smaller air density means that they encounter less air resistance.

The feeling of running here needs to be fine-tuned.

Then, using the Reynolds number and boundary layer theory, the dynamic viscosity coefficient of air in the thin air of the plateau is relatively low. For example, when the speed and characteristic length remain unchanged, the changes in the air density and dynamic viscosity coefficient of the plateau will affect the Reynolds number. The lower Reynolds number makes the airflow in the boundary layer closer to the laminar state. Compared with the turbulent boundary layer in the plains, the laminar boundary layer produces less air resistance. This helps sprinters reduce energy loss during the acceleration phase, allowing the body to move forward more efficiently.

In addition, the thin air makes the wake area behind the athlete relatively smaller in scope and intensity, so the Bernoulli equation is used.

The pressure change in the wake area is one of the main reasons for the pressure difference drag.

In plateau environments, the pressure changes in the wake zone are reduced, and the pressure difference resistance experienced by athletes is reduced. This allows athletes to use more of their energy for forward movement rather than overcoming resistance during high-speed sprints.

After doing these calculations, check your anaerobic metabolic capacity. After all, the plateau environment causes a series of adaptive changes in the human body.

Moreover, from the perspective of energy metabolism, sprinting mainly relies on the phosphagen system and the glycolysis system to provide energy, and the former belongs to absolute anaerobic metabolism. In plateau areas, due to the low oxygen partial pressure, the body will increase the proportion of anaerobic metabolism to a certain extent. This metabolic method can provide energy faster in short-term, high-intensity sprinting events, because the anaerobic metabolic system can quickly synthesize ATP without the participation of a large amount of oxygen, providing energy for muscle contraction, allowing athletes to burst out more powerful power at the start and extreme speed stages.

Therefore, it is very likely that a longer extreme speed burst point will be tested here.

Test your muscle excitability again.

This is because - in plateau environments, the human nervous system will undergo adaptive changes.

On the one hand, the excitability of the sympathetic nerves is relatively enhanced, which will increase the contraction speed and strength of the muscles to a certain extent. On the other hand, the excitability of the muscle cell membrane will also change, and the activity of ion channels may change.

For example, a moderate increase in calcium channel activity makes the release and utilization of calcium ions more efficient during muscle contraction, thereby enhancing muscle contraction performance and helping to improve sprint performance.

He also needs to see how moderate the activity of his ion channels is.

See how much the muscle contraction feels increased.

Then comes today’s key topic.

Or it should be said that it is the key topic of the entire plateau competition venue - the potential optimization of stride frequency and stride length.

To put it simply: in a plateau environment, due to the reduced air resistance, the athlete's body swing and limb movement are relatively less subject to external interference during running.

From the perspective of sports biomechanics, this helps athletes better control their stride frequency and stride length.

Athletes can adjust the order and size of muscle force more accurately here to achieve a more optimized combination of step frequency and stride, thereby improving running efficiency.

For example, Su Shen wanted to try, under the condition of reducing air resistance, could he use the elastic potential energy of leg muscles more effectively? Properly increase the stride length without excessive energy consumption? And thus improve the overall sprint speed?

If you can achieve your own super cadence, can you make further breakthroughs?
Can your own dissatisfaction be relatively speaking achieved while maintaining a super-cadence and at the same time being able to play more freely?

All these need him to verify in the game.

No matter how much training we do, it is just training. Whether complicated problems will arise will only be known in the competition.

In the previous life, I liked Su Shen who used competition as a form of training.

Know the difference between the two better than anyone.

If it can be done.

Next game.

If you go to New York.

Face Bolt again.

The chances of winning will increase.

……

Randy looked at the densely packed "Training and Research Topic List" of Su Shen and felt...

It’s a bit like going back to when I was writing my thesis in college.

Being with this guy, he finally understood what science without boundaries meant.

So many scientific things can be used in running.

There were many aspects and points that he had never thought of before.

However, he was able to use a variety of scientific formulas, scientific algorithms and scientific models to make precise guided calculations.

this ability.

Ralph Mann is also a scientific athlete.

Everyone has to say it - it's incredible.

He originally thought that when he got older, would there be no scientific research athletes who could take over his job?

This doesn't mean that you can just have the title of a scientific research athlete.

It’s enough that this isn’t the messy certification on Weibo and Twitter.

What we need are people who truly have the ability and willingness to conduct scientific research.

Only then can you take the baton from your hand.

Continue to contribute driving force to human sprinting and track and field events.

Just like my own champion model.

Just like the front-side mechanics of himself and Su Shen.

He really hopes and looks forward to it...

Human sports science can complete progress that would normally take decades or even hundreds of years in one go, with two batons handed over in one era.

Of course he had thought it impossible before.

Even Randy is far behind him in terms of pure scientific research ability.

Let alone the rest.

After I am gone, no one can continue to push human athletics forward at a high speed. This is truly a pity.

But what about now?
He thought it was possible.

One after another.

It's not just about going forward.

This successor.

It is also very important.

Fortunately.

He has seen this person.

Bang bang bang bang bang.
