High-altitude training is a point in modern times that is increasingly researched—
First of all, at high altitude areas, the air density is low, which reduces the sense of air resistance faced by sprinters when running at high speed. Since speed is a key factor in sprinting events, the reduction of air resistance may have a positive impact on the performance of sprinters.
Secondly, the maximum oxygen intake and lactate threshold in high-altitude areas will be reduced, which means that when performing the same exercise intensity at high-altitude areas, the body will experience a higher sense of exercise load. For anaerobic exercise, which is mainly based on phosphate metabolism, this change has basically no effect. For long-distance running, aerobic metabolism projects, performance will be negatively affected and performance will decrease significantly.
So sprinting is very suitable, long-distance running is the opposite.
Then high-altitude training can increase the amount of hemoglobin in the blood and thus increase the oxygen transport efficiency during exercise. This adaptation may be beneficial for sprinters, because sprinting mainly relies on anaerobic metabolism, and the increase of hemoglobin can improve the ability of anaerobic metabolism.
But after saying so many benefits, there must be disadvantages.
In the past, we had a long-term plateau training, which had the opposite effect.
This is because due to the altitude adaptation, athletes' hemoglobin concentration, blood volume, and buffering ability will increase, skeletal muscle structure and biochemical characteristics will improve, and the adaptation of the altitude environment can reduce cardiopulmonary discomfort caused by chronic hypoxia.
However…Plateau training will not improve VO.
Because of the effect of plateau training, the increase in blood cell density, the right shift of the oxygenated hemoglobin dissociation curve, the increase in the diffusion capacity of the lung gas, etc., may be offset by other negative effects.
Such as blood flow in the chest cavity and peripheral tissues, reduction of muscle mass, reduction of oxidase activity, etc.
When athletes go from plateau to plains, their bodies will offset the benefits of plateau training due to the decrease in plasma volume, slowing down hematopoiesis, accelerating hemolysis, inhibited immune function, oxidation pressure increases tissue damage, increased glycogen consumption and increased workload of respiratory muscles.
Long-term staying in a high-altitude environment will lead to atrophy of skeletal muscles, especially the higher the altitude, the more obvious it is. Continuously being in an hypoxic environment will reduce the cross-sectional area of ​​the muscle by 10%-22%.
Therefore, it is not advisable to train here for a long time, so you must plan and match it well.
Then use the lactic acid paradox to improve your body functions and improve your grades.
Because when the altitude increases, the concentration of blood lactate will be lower. Although the mechanism is still debated, it is certain that athletes adapted to the plateau environment will produce less lactic acid during maximum intensity exercise.
Note that the amount of lactic acid production decreases during the maximum intensity exercise above, rather than the lactic acid removal becomes faster.
This is a new achievement of modern science.
This is because when the energy supply is satisfied, the ATP energy supply ratio increases and rapid glycolysis decreases.
But the effect generally does not exceed six weeks.
If you are in a hypoxic environment for a long time, for more than six weeks, this phenomenon will disappear.
Therefore, Su Shen now needs to develop a relatively advanced improvement mechanism, and based on the above principles, do a good job of "staying high and practicing low".
This training method allows athletes to live in high altitude areas for several hours every day before moving to low altitude during training.
But this is too troublesome, because it is not an easy task to change from high to low with a terrain.
The distance is usually very long.
So, is there any solution?
Of course there is.
It is relying on the increasingly mature sports technology at this stage.
For example, what Su Shen is doing now is a new product launched by his Su Shen Laboratory—
Simulate a low oxygen device at high altitude.
And simulate high oxygen devices at low altitudes on plateaus.
In doing so, plateau adaptation can increase the amount of hemoglobin production, heme and hemoglobinopolybin, which helps athletes train at higher intensity in plains or at low altitudes.
Living on a plateau at an altitude of 2200-2500m can help increase hemoglobin production.
At an altitude of about 3100m, it is the most effective way to improve other parameters except blood.
The best period to accelerate hemoglobin production is about 4 weeks, and training less than 3 weeks can improve the economy of exercise and acid-base buffering ability.
Staying at an altitude of 2500m for 20-22h/d every day is enough to improve exercise performance and promote hemoglobin production effect. The bottom limit for promoting hemoglobin production effect is 12h/d.
These data are clearly arranged by Su Shen.
Especially when he decided to do this this year, the first time he was actually the most responsive and intense to the body.
He strictly follows the scientific process to carry out the "high-stay-low-training" model. This training started from Ersha Island this year. He used high technology and just performed it repeatedly, and then waited for the physical indicators to rebound before continuing to adapt to it again.
The advantage of having precise data guidance is that you can mark both the best and the worst.
Make yourself get as much benefits as possible and reduce the disadvantages.
At this point in time, most people only know this concept.
These clear data metrics.
It will take a few more years before the laboratory will verify it bit by bit.
It’s different here in Su Shen.
He had the answers directly, and then deliberately guided the geniuses in the laboratory to do this direction.
Avoiding the wrong path and trial and error, it will naturally be smooth.
Do you think Su Shen said this year that he would let all athletes take advantage of others' troughs and kill them while they are sick.
Are you kidding?
That's not just an improvement in training methods.
Training technology also needs to be improved.
It's not just the targetedness of running shoes and tracks.
There are also black technology products guided by the accuracy of scientific data from various scientific indicators.
Accurate data is the most rare thing.
Although there are also research on this aspect, such as in Europe and the United States, there are also "Altitude training for elite endurance athletes: A review for the travel medicine practicer", "Review of Athletic Guidelines for High-Altitude Training and Acclimatization", "Simulated Altitude Training and Sport Performance: Protocols and Physiological Effects", etc.
This chapter is not over, please click on the next page to continue reading! It is translated as "Plateau Training for Elite Endurance Athletes: A Review of Medical Practitioners", "Summary of Guidelines for Plateau Training and Adaptation Athletes", "Simulated Plateau Training and Athletic Performance: Protocols and Physiological Effects"...
Unfortunately, they are still in the exploration stage and have not confirmed a certain accurate data like Su Shen.
Therefore, although the research aspect is very cutting-edge, people who really dare to start and do it with the greatest benefit only, and there are almost no disadvantages...
Except for Su Shen’s current team.
None of them can be done.
Even if many people do this, they often experience some uncontrollable negative effects because they do not have accurate scientific theories and scientific data.
And these aspects are in Su Shen’s side.
It basically won't appear.
This also means that Ersha Island will hardly appear.
Only in front of them can they truly maximize the use of this plateau training.
At least within 50 years.
No new argument can surpass them.
In addition, last year was the Olympic Games, and most people's bodies have entered a state of weakness and rest this year. However, the opposite is true for the Zanhua Family. Not only do they recover from fatigue through black technology training, maintain their state, and even have better intensity. At the same time, they also used the "perfect version of the plateau training method" promoted by the team led by Su Shen, and used the black technology instruments that can complement each other whether you are on a plain or a plateau.
Tell me.
I'm afraid it's hard to be in a bad state today.
It may even be the year with the smallest gap between everyone and world-class athletes this year.
This is definitely not talking nonsense.
Of course, in addition to these basic skills, Su Shen has achieved almost perfection, and he also has advanced projects.
First of all, the LSD training method, also known as low-intensity continuous training, can challenge the human aerobic metabolism ability in a plateau environment. Arrange low-intensity continuous LSD training, such as running at an intensity of 30-60 minutes, and control the speed to a level that allows easy conversation. This helps improve cardiopulmonary function, adapt to the low-oxygen environment of the plateau, and increase oxygen intake and transportation efficiency.
Next, using the air resistance formula, precise calculations are made to allow athletes to obtain higher speeds under the same force than in plain areas under the plateau environment.
This is because the air pressure in plateau areas is lower and the air density is relatively small. According to the principle of fluid mechanics, the resistance that objects experience when moving in fluid is proportional to the density of the fluid. During running, the smaller air density means that the air resistance they receive is reduced.
The feeling of running here needs to be fine-tuned.
Then, using the Reynolds number and boundary layer theory, the dynamic viscosity coefficient of the air in the thin plateau is relatively low. For example, when the velocity and characteristic length are unchanged, the changes in the plateau air density and dynamic viscosity coefficient will affect the Reynolds number. The lower Reynolds number makes the air flow in the boundary layer closer to the laminar flow state, and the air resistance generated by the laminar flow boundary layer is smaller than the turbulent boundary layer in the plain area. This is conducive to sprinters reducing energy loss during the acceleration stage and allowing the body to advance more efficiently.
The thin air makes the range and intensity of the wake zone formed behind the athletes relatively reduce, so the Bernoulli equation is mobilized——
The pressure change in the wake region is one of the main reasons for the pressure difference resistance.
In a plateau environment, due to the decrease in pressure changes in the wake area, the pressure difference resistance of athletes is reduced. This allows athletes to use more energy for forward movement rather than overcome resistance during the high-speed sprint stage.
After doing these calculation questions well, check your anaerobic metabolism ability. 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 phosphogenic system and glycolysis system to provide energy. The former is absolute anaerobic metabolism. In plateau areas, due to the low partial pressure of oxygen, the body will increase the proportion of anaerobic metabolism to a certain extent. This metabolic method can provide energy faster in short-term and high-intensity sprinting events, because the anaerobic metabolism system can quickly synthesize ATP without the participation of a large amount of oxygen, providing energy for muscle contraction, and allowing athletes to burst out stronger power at the starting and extreme speed stages.
Therefore, it is very likely that tests here, a longer rapid explosion point.
Test your muscle excitability again.
This is because in a plateau environment, the human nervous system will undergo adaptive changes.
On the one hand, the excitability of the sympathetic nerve is relatively enhanced, which will increase the muscle contraction speed and strength to a certain extent. On the other hand, the excitability of the muscle cell membrane will also change, and the activity of the ion channel may change.
For example, for example, the moderate increase in the activity of calcium ion channels makes the release and utilization of calcium ions more efficient when muscle contraction, thereby enhancing muscle contraction performance and helping to improve sprint performance.
He also needs to see how moderate his ion channel activity is.
Look at how much the muscle contraction feels.
Then there is today's key topic.
Or it should be said that it is the key topic of the entire plateau competition venue - potential optimization of step frequency and stride width.
Simply put, in a plateau environment, due to the reduction of air resistance, the external interference of athletes' body swing and limb movement during running is relatively reduced.
From a sports biomechanical perspective, this helps athletes better control stride frequency and stride length.
Athletes can more accurately adjust the order and size of muscle force, so that the pace frequency and stride length can be combined more optimally, thereby improving running efficiency.
For example, what Su Shen wants to try is, can he use the elastic potential energy of the leg muscles more effectively while reducing air resistance? Appropriately increase the stride without excessive energy consumption? In turn, improve the overall sprint speed?
This chapter is not over, please click on the next page to continue reading! If you can achieve your own super pace frequency, can you make further breakthroughs?
Can you relatively speaking your dissatisfaction be more open while taking into account the super step frequency?
All of these need to be verified in the game.
No matter how much training is, it is just training. Whether there will be complex problems will occur, and it will only be known in the competition.
Su Shen, who liked to use the competition to practice in his previous life.
More than anyone else, the difference between the two is known.
If it can be done.
Next game.
If you go to New York.
Face Bolt again.
The chances of winning will be improved a little.

Randy looked at the dense "training research topic list" of Su Shen, and she felt...
I was a little bit back when I was writing my thesis in college.
Only when he was with this guy did he understand what science was boundless.
So many scientific things can be used in running events.
Many aspects and points were something he had never thought about before.
However, he has been able to use various scientific formulas, scientific algorithms and scientific models to make precise guidance and calculations.
This ability.
Ralph Mann, who is also a scientific research athlete.
You have to say the heights - it's amazing.
He originally thought that when he got old, wouldn’t the scientific research athlete not be able to take over his class?
This is not to say that you can just be the title of a research athlete.
This is not enough for scarves and the messy certifications on Twitter.
What we need is people who have real scientific research capabilities and willingness to research.
Only then can you take away the baton from your own hands.
Continue to contribute to the driving force of human sprinting and track and field events.
Just like your own championship model.
Just like the frontal mechanics of myself and Su Shen.
He really hopes and looks forward to it...
Human exercise science can achieve progress that may take decades or even hundreds of years in one breath in one era.
Of course he thought it was impossible before.
Even Randy is still very different from him in terms of pure scientific research ability.
Don't talk about the rest of the people.
After leaving by itself, no one can continue to push the human track and field market at a high speed. This is a pity.
But what about now?
He felt it was possible.
Go one after another.
What you want is more than just a trip.
This successor.
It is also very important.
Fortunately.
He has seen this person.
Bang bang bang bang bang bang bang.
It was this man who kept running repeatedly on the blue track.
The guy who keeps thinking about data and models after running again and again.
Let me see.
How many surprises are waiting for us.
