Chapter 2196 Conversion of Gravitational Potential Energy and Kinetic Energy - Extreme Breakthrough is Coming

Su Shen was in excellent shape during the run today.

The purpose of choosing the plateau.

Now start to manifest.

All the previous competitions and the implementation of practical technologies one by one are for now.

He wants to be in this one.

Put the things you made earlier.

Show it thoroughly.

he.

To push your limits.

We must also break through the limits of the yellow race.

Even.

Help all mankind.

Break through the limit once.

Zhao Haohuan felt it...

Su Shen in front.

Definitely stirring up trouble.

He ran during this shot.

Scary smoothness.

This guy.

Even though it is like this, why can we still break through???
It's terrible.

too frightening.

No.

I don't think I ever saw him stop.

Su Shen feels great!

It's going to be very fast soon.

He wants to take advantage of his previous accumulation and make a big move here.

He wants to optimize his cadence and stride length.

It’s not just about reaching the acceleration zone.

You also have to run ahead on the way.

It is not enough to reach the front halfway.

We also need to cover the core areas along the way -

Speed zone!

call--

Ventilate!

Adjustment of the respiratory system.

The air in plateau areas is thin and the oxygen content is low. The human body will increase lung ventilation by increasing breathing frequency and depth to absorb more oxygen.

At the same time, the respiratory muscles will be exercised and become stronger.

During sprinting, strong respiratory muscles can better maintain the stability and rhythm of breathing, provide the body with a stable supply of oxygen, and ensure the energy production of muscles during aerobic and anaerobic metabolism, which is beneficial to the development of strength, especially in short-term and high-intensity sprinting. It has a positive effect on the improvement of vertical force and horizontal force.

Su Shen's Breath of Su.

Strong point.

It is possible that others here may not be able to breathe smoothly.

I can't get used to such a good meal buff.

But all this was impossible for Su Shen, who had been preparing for many years.

Really.

It's not a problem at all.

Su's breath, inhaling forcefully.

A lot of oxygen enters.

The blood becomes active.

This also improved the adaptability of his cardiovascular system.

It should be noted that in the high-altitude hypoxic environment, the human cardiovascular system will undergo a series of adaptive changes.

On the one hand, the heart will increase cardiac output by increasing heart rate and stroke volume to ensure oxygen supply to various organs of the body. On the other hand, vascular endothelial cells will release some vasoactive substances to dilate blood vessels, reduce peripheral vascular resistance, and promote the secretion of erythropoietin, stimulate bone marrow hematopoiesis, increase the number of red blood cells and hemoglobin, and improve the oxygen carrying capacity of blood.

These changes allow muscles to obtain more adequate oxygen and nutrients during exercise, provide better energy support for muscle contraction, and help improve muscle strength, including vertical and horizontal force.

The buff is here.

It all depends on whether you can take it away.

I can carry it!
For example, people from the traditional field are useless even if you give them a chance.

The buff is placed here.

You can’t take it away even if you want to.

This is sad.

He saw the treasure, but couldn't move it because he didn't have the ability.

You say it's irritating or not.

As cardiovascular adaptation improves, muscle metabolism also changes because the hypoxic environment causes adjustments in metabolic pathways within muscle cells.

On the one hand, the activity of enzymes related to anaerobic metabolism, such as phosphofructokinase and lactate dehydrogenase, is enhanced, which accelerates the glycolysis process and can produce more adenosine triphosphate in a short period of time, providing a quick source of energy for muscle contraction.

On the other hand, muscle cells will increase the uptake and utilization of fatty acids and improve aerobic metabolic capacity to conserve limited glycogen reserves.

This change in metabolism enables muscles to use energy more efficiently in high-altitude environments and generate greater contraction force, allowing them to exert greater power both in the vertical direction of pushing off the ground and in the horizontal direction of propulsion.

This is one of the reasons why it is easier to achieve maximum speed in plateau areas below 3000 meters.

Su Shen chose here.

Definitely well thought out.

joke.

The site selection in this life is all invested with real money. After spending so much money, the country has benefited and the athletes have also benefited.

Then you should always let yourself take advantage of it.

After all, only when personal interests and collective interests are combined can things last truly long.

There are probably not many people who can be a saint who only does good things for the collective benefit without caring about personal interests.

So this is also for my own breakthrough this season.

The plan was set up early.

Otherwise, wouldn’t such a good place be wasted?
This year, we specially carried out preparatory training for plateau conditions and invested in black technology.

What do you think it was for?
Isn't it just about preparing the body in advance for continuous plateau combat?

In this way, during the mid-running stage, the reduction in air resistance will help Su Shen maintain a higher speed, reduce energy loss, and enable more force to be converted into horizontal force to propel himself forward.

At the same time, the reduction in air resistance will also affect Su Shen's movement posture and muscle exertion. Here, Su Shen can complete movements such as swinging his arms and pushing off the ground more smoothly, which is conducive to the transmission and exertion of force, and indirectly affects the generation of vertical force.

Prepare the physical foundation.

This is the prerequisite for all technologies to be implemented well.

Not to mention that muscle fibers will become thicker on the plateau.

This is because hypoxic stimulation will increase protein synthesis in muscle cells, especially the synthesis of contractile proteins such as actin and myosin, which increases the diameter of muscle fibers.

Thicker muscle fibers can produce greater contraction force. In the 100-meter sprint, both the vertical pushing off the ground and the horizontal leg swinging and propulsion movements require strong muscle strength to achieve.

As muscle fibers become thicker, their cross-sectional area increases. According to the physiological mechanism of muscle strength generation, the cross-sectional area is directly proportional to muscle strength. Therefore, it can generate greater vertical and horizontal components of force, which helps to improve sprinting performance.

Mitochondrial number and function also increase.

Mitochondria are the main site of aerobic respiration in cells, providing energy for muscle contraction.

In the high altitude hypoxic environment, muscle cells adapt to the insufficient oxygen supply by increasing the number of mitochondria and improving their function.

More mitochondria means that muscle cells can use oxygen more efficiently for aerobic metabolism, producing more ATP.

In the 100-meter sprint, although anaerobic metabolism is the main source of energy, aerobic metabolism also plays an important auxiliary role, especially in the acceleration phase after the start and in the process of maintaining high-speed movement.

The increase in the number and function of mitochondria enables muscles to replenish energy in a timely manner during exercise and reduce fatigue, thereby ensuring that muscles can continuously generate greater force, which is conducive to the stable exertion of vertical and horizontal force components.

The higher it is, the easier it is to manifest.

Coupled with increased catecholamine secretion.

Catecholamines can promote glycogenolysis and fat mobilization, providing more energy substrates for muscle movement.

At the same time, it can enhance myocardial contractility, increase heart rate, increase cardiac output, and provide muscles with a more adequate blood supply.

In the 100-meter sprint, these effects of catecholamines help increase muscle energy metabolism levels, enhance muscle contraction ability, and thereby increase vertical and horizontal force components.

The increased secretion of catecholamines can make the muscles quickly enter a state of excitement, generate strong explosive power, and provide sufficient vertical force and high horizontal speed for starting.

These characteristics.

All in plateau areas.

Especially here.

Qingtang City.

After finishing all of this, we will start the formal preparation phase for today's rapid explosion.

Conversion of gravitational potential energy and kinetic energy.

The so-called conversion of gravitational potential energy into kinetic energy means that when athletes push off the ground during the starting and acceleration phases, their leg muscles contract to generate upward and forward force.

At this time, the body's center of gravity rises and the speed temporarily decreases.

This transformation process enables athletes to obtain upward support and forward acceleration, creating conditions for subsequent fast running.

The conversion of gravitational potential energy into kinetic energy is different.

After the athlete pushes off the ground and enters the airborne stage, the body's center of gravity begins to drop, the height h decreases, and the gravitational potential energy gradually decreases. At the same time, due to the effect of gravity, the body gains downward acceleration in the vertical direction, and maintains a certain speed in the horizontal direction due to inertia, the overall speed gradually increases, the kinetic energy increases, and the gravitational potential energy is converted into kinetic energy.

When the athlete lands, the center of gravity of the body continues to drop, and the gravitational potential energy is further converted into kinetic energy, allowing the athlete to run forward at a high speed.

This is the basic principle of the conversion of gravitational potential energy and kinetic energy in sprinting.

Utilize the conversion of gravitational potential energy and kinetic energy.

It can effectively optimize the ground pushing efficiency and take-off dynamics.

And the synergistic effect of air resistance reduction and energy conversion.

In plateau areas, the generation of vertical force F_v follows Newton's second law:
F_v - mg = ma_v.

Due to the reduction of g value, the vertical acceleration a_v is significantly improved under the same ground pushing force. Experimental data show that the a_v of athletes pushing off the ground at 2200-2500 meters on the plateau is 12%-15% higher than that on the plain, and the flying height is increased by 3-4cm.

A higher flying height allows athletes to convert more gravitational potential energy into horizontal kinetic energy during the falling process, directly promoting an increase in horizontal speed.

But everything has pros and cons.

How is it possible that you get all the good things?

For example, at this time, the lower gravitational acceleration prolongs the flight time, about 0.02-0.03s/step.

To offset this, athletes are required to precisely control the timing and angle of landing to avoid loss of horizontal speed.

At this time, the synergistic effect of reducing air resistance and energy conversion is utilized.

It becomes crucial.

Otherwise you just go this route.

Will find out.

As the altitude increases, the ineffective time also increases.

At this time, reasonable technical optimization is needed.

While retaining the advantages as much as possible.

Minimize shortcomings as much as possible.

In addition, the efficient conversion of vertical gravitational potential energy into horizontal kinetic energy forms a synergistic effect with the reduction of air resistance. When the athlete falls from the air, the kinetic energy converted from gravitational potential energy is directly superimposed on the horizontal speed, further amplifying the acceleration effect of the horizontal component force.

Combining the two, it is possible to complement each other's strengths and overcome each other's weaknesses.

So what are you waiting for?

Start.

Explode.

Su Shen looked at the distance ahead.

I guess it feels good.

Said secretly:
Extreme speed.

Liberate it.

Bang! ! ! !

Deep coupling of energy metabolism system and conversion efficiency!

The transient driving effect of the phosphagen system!

Open!
During muscle contraction, ATP is broken down into adenosine diphosphate (ADP) and phosphate under the catalysis of ATPase, releasing energy.

However, the ATP reserves in muscles are limited, about 5-7mmol/kg, which can only sustain high-intensity exercise for a very short time. At this time, creatine phosphate CP plays a key role as an energy reserve substance.

Under the action of CP enzyme, the high-energy phosphate bond in the CP molecule transfers the phosphate group to ADP to quickly synthesize ATP.

The output energy increases from 35kJ/(kg·s).

36 kJ/(kg·s).

37 kJ/(kg·s).

38 kJ/(kg·s).

39 kJ/(kg·s).

40 kJ/(kg·s).

……

Continuously improve.

No intention of stopping at all.

At the moment of starting, the ATP-CP system can provide more than 90% of the energy required for muscle contraction, allowing Su Shen to generate powerful pushing force in a very short time.

This is the origin of rapid liberation.

The phosphagen system drives energy conversion.

Correlation with initial kinetic energy generation.

At the moment of starting and pushing off the ground, the energy provided by the ATP-CP system directly drives the muscles to contract rapidly, generating a strong ground reaction force.

According to Newton's second law F = ma, a greater push-off force (F) allows the athlete to achieve a higher acceleration (a), thereby increasing the initial velocity (v). According to the kinetic energy formula, the increase in speed directly leads to a significant increase in initial kinetic energy.

Next comes the promotion of the conversion of gravitational potential energy.

The powerful force of pushing off the ground not only increases the kinetic energy in the horizontal direction, but also significantly improves the body's center of gravity in the vertical direction.

According to the gravitational potential energy formula E_p = mgh, the increase in the center of gravity height h directly leads to the increase in gravitational potential energy. The instantaneous energy provided by the ATP-CP system enables muscles to have stronger explosive power, can generate greater vertical force, and push the body's center of gravity to rise rapidly.

Studies have shown that during the starting phase, the athlete's vertical acceleration can reach 3-4g, where g is the acceleration due to gravity. During this process, about 30%-40% of the energy is used to raise the height of the center of gravity.

If the ATP-CP system is under-powered, the ground-pushing force will be weakened, the vertical acceleration will decrease, and the generation of gravitational potential energy will be reduced, affecting the energy conversion efficiency in the subsequent takeoff stage.

At this time, the vertical force and horizontal force components prepared earlier are used together.

That’s the first step to the solution.

Conversion of gravitational potential energy and kinetic energy.

This is the second step.

The third step is to use these to mobilize the precise regulatory mechanisms of neuromuscular control.

For example, the spatiotemporal coding characteristics of nerve impulses.

The nervous system controls muscles through nerve impulses, whose temporal and spatial coding characteristics directly affect the efficiency of energy conversion.

Just like in the action of pushing off the ground, the brain needs to precisely control the timing and intensity of the release of nerve impulses.

Nerve impulses that are too early or too late can cause muscle contraction to be out of sync with the push-off action, wasting energy.

Nerve impulses that are not strong enough cannot enable the muscles to generate sufficient force.

But at this time, the release of nerve impulses by excellent athletes can be highly precise in time and space.

Then we can——

It enables multiple muscle groups to contract synergistically, efficiently converting energy into kinetic energy and gravitational potential energy in a very short time of 0.1-0.2 seconds.

This is what Su Shen wants to do.

Utilizing dual-force integration and the spatiotemporal coding characteristics of nerve impulses, gravitational potential energy and kinetic energy can be efficiently converted.

Completely ignite its own six-second rule.

Six-second burst.

Performance is improved again.

They are all in the third stage of six-second burst.

But performance.

There is still a difference between high and low, good and bad.

Su Shen wants to further unleash his extreme speed.

Further exploit the transient driving effect of your own phosphagen system.

Allow yourself to break through your own breaking point.

Break through your own speed limit.

A huge amount of energy burst out.

Zhao Haohuan is the closest one.
