The hourly decrease in productivity of the whole organism, organ and tissue that comes after work is called second.
Then you know after a much less trivial repair. The volume of isolated meat can be more easily preserved by pouring small portions of the meat onto it.
The height of such meat will soon change step by step until the meat stops being felt. The more often the irritation is applied, then the end comes (Fig.).
Training in humans is carried out using an additional special device - an ergograph (Fig. 2).
Small SPEED OF THE ATTACK INSTALLED AT DIFFERENT FREQUENCIES DRAFTING 1-speed with frequency - once per second; 2 - speed up with frequency once every 2 seconds: 3 - speed up with frequency once every 4 seconds.
The ergograph is a device in which the forearm and pensel are fixed , II and IV fingers of the traced one. Raise the tension up to the middle finger and follow the instructions to lift and lower it, bending and unbending the finger. By changing the rhythm of work, the magnitude of the influence is different, you can understand the phenomenon that arises in people of different minds.
The curve, as it appears, is called an ergogram (Fig. 3).
For the training of working staff I. M. Sechenov designed a special erograph, in order to further trace the patterns that occur when sawing with a hand file.
To clarify this, a bunch of theories were thrown in the air. Some attributed the fatigue to the fact that as a result of the work, energy reserves were depleted, while others assumed that the reason for the fatigue was the contamination of meats with decomposition products. However, the desire for hanging theories is not beforeput a further explanation of the phenomena in the second place. When the work is strengthened in the meat, decomposition products are effectively resolved, lactic acid is created, which significantly contributes to the tension in the working meat, energy reserves are wasted, etc., and so on. day from these processes we cannot but positions the basis of the explanation. All these theories ignored the role of the nervous system in acute depression.
Tim has been researching for an hour I. M. Sechenova, I. P. Pavlova, N. E. Vvedensky and A. A. Ukhtomsky have shown that in the most important saving of efficiency and in the present time the central role plays a vital role.

Insistence of meat during reflex infusion with special evidence from N. E. Vvedensky. This confirmation of placements on such a matter, the shortness of which could reflexively result in the disintegration of two different people.assistant professor's nerves. The destruction of one of these nerves reached the same meat. When it became obvious that the muscle was worn out, the other precentral nerve was irritated. During the process of tearing, the flesh produced a lot of force. The whole system has been fragmented, so that fatigue directly affects the muscles and the central nervous system (the nerve fiber is almost indestructible).
Having poured measles into the cerebral cord, there were indications from the witness, when he reached the person who was supposed to work on the work, it became clear that he was losing the easy work; its energy consumption changed, although the intensity of the work did not decrease.
When light meat work is eliminated, energy expenditures increase sharply, as evidenced by the fact that the importance of physical work is eliminated.
The influx of the autonomic nervous system, from the point of view of the sympathetic body, was shown by the Radiansky teachings of L. A. Orbel and A. G. Ginetsinsky.
After the toad meat was consumed, the sympathetic nervous system was treated and the meat’s usefulness was preserved. The irritation of the sympathetic nerve causes a change in the metabolic processes that occur in the muscle, as a result of which comes a renewal of efficiency.
In this way, the influx of the autonomic nervous system into the processes that occur in the skeletal system was first introduced.
Rice. Ergogram
Pretty, who plays, as described above, an important role, is itself under the immediate regulatory influx of the central nervous system. Any meat activity is only possible without coordination with the central nervous system, where it constantly receives low impulses from the receptors of various organs that take part from the robot.
The mind is wide-open, and the best way to renew your productivity is to achieve greater peace. Prote investigation I. M. Sechenov was brought to the conclusion of the cruelty of such a phenomenon. Having renewed the usefulness of the tired work of the right hand in the minds of theIf the left hand finished the song, then there was an hour of active repair. It turned out that efficiency is promoted more as an active substitute than a passive one.
The flow of impulses that flow directly from the working hand into the central nervous system is transmitted, which occurs during fatigue or when the part of the central nervous system goes into galvanization.
There are the following modes of meat shortening:
1. Isotonic shortness of breath. The muscle tone changes, but the tone does not change. Rukh functions do not take the fate of the body.
2. Isometric shortening. Even though the muscle does not change, the tone increases. Be the basis of static work, for example, for maintaining body position.
3. Auxotonic shortening. Both supper and meat tone change. They help with drying out the body and other drying acts.
Maximum strength of muscles– this is the value of the maximum voltage that can expand the muscle. It will lie down in the future, the functional state, the weekend, as well as the state, age, and level of fitness of a person.
It is common to see flesh with parallel fibers (for example, kravetska), spindle-like (double-headed shoulder meat), feathers (lithic). These types of meats have different sizes area of transverse physiological transection- This is the area of the transverse section of all meat fibers that process the meat. The largest area of transverse physiological cross-section, therefore, and strength, is found in cirrus meats. The smallest amount in meats is from parallel growth of fibers.
When the muscle is moderately stretched, the strength of its contraction increases, but when it is overstretched, it changes. When moderately heated, the force increases, and when cooled, it decreases. The strength of the muscles decreases when metabolism is disrupted, etc. The maximum strength of the meat groups is measured by dynamometers (wrist, we become thin).
To equalize the strength of various meats, use them pitu chi absolute power. Won is of maximum strength, divisions per square meter. div. area of the transverse cut of the flesh. The power of pita meat of humans is 62 kg/cm 2 , trigoli - 16.8 kg/cm 2 , zhuvalny - 10 kg/cm 2 .
Divide work into dynamic and static Dynamic ends at the hour of displacement. During dynamic operation, the voltage and voltage changes. Also, the meat processes in an auxotonic mode. At static there is no importance in moving robots, then. The meat is processed in isometric mode.
The dynamic work of the modern work will increase the height of the leg or the amount of shortening of the muscle (A=M·h). The work is measured in kg m, joules. The dependence of the value of the work on the demand is subject to the law of averages. In times of increasing importance, the work of the muscles is growing. At medium pressures, the value becomes maximum. As demand continues to increase, the workload decreases. Such an influx of robotic value creates a rhythm. The maximum performance of the muscle is at the average rhythm. p align="justify"> Particularly important in the expansion of the size of the working force is the importance of the tension of the muscle - this robot is equal to one hour (P = A · T). The unit of vimiru is vat (W).
Vtoma m'yaziv
Vtoma- This is a temporary decrease in the productivity of meats as a result of the work. The volume of isolated meat can be used for its rhythmic disintegration. As a result, the strength will soon change progressively. The greater the frequency, the strength of the tease and the magnitude of the intensity, the faster it develops. When fatigued, the curve of a single exercise significantly changes. The duration of the latent period increases, the period is shortened and especially the relaxation period, and the amplitude decreases. The stronger the meat, the greater the distress of these periods. In such cases, complete relaxation does not occur. Developing contracture- This is the camp of the dry, fleeting shortening of meat.
The work is also followed by additional erography. In the last century, on the basis of studies from isolated meats, 3 theories of meat production were established.
1. Schiff's theory: fatigue and subsequent depletion of energy reserves in meat
2. Pfluger's theory: fatigue is due to the accumulation of meat products of exchange
3. Verworn's theory: fatigue is explained by a little sourness in the meat
It’s true that officials are tired of experiments with isolated meats. Their ATP resynthesis is disrupted, lactic and pyruvic acids accumulate, and there is insufficient acidity. However, in the body of meat, which is intensively processed, removing the necessary sourness, life-long substances are formed as metabolites for the purpose of strengthening the renal and regional blood circulation. This was the basis for other theories. Zokrema, the singing role will belong to you nerve-muscle synapses. The synapse develops through the depletion of neurotransmitter reserves. However, the main role in the second apparatus belongs to the motor centers of the central nervous system. In the past century I.M. Sechenov established that it is time to work on one hand, their usefulness is renewed more and more every hour of work with both hands and feet. It is important to note that this is connected with the alternation of awakening processes from one orbital centers to others. As a result of the inclusion of other meat groups, we named active.
It has now been established that rukhova vtoma is associated with galvanization of the spinal nerve centers, as a result of metabolic processes in neurons, decreased synthesis of neurotransmitters and suppressed synaptic transmission.
When you start playing sports, your body recognizes great physical demands - all this changes the body of your muscles. After intensive work, the stench gets tired and changes. In this article, I will tell you how importance flows into the development of meat, which processes occur in meat tissue and how it flows into training. This knowledge is to blame for the skin problem of those who engage in bodybuilding, whether they are amateurs or professionals, girls or men.
This is a physiological process that results in a decrease in the productivity of meat fibers through intense or wasteful work, which changes their yield, strength and fluidity.
After losing the desire, they are often deprived of short-lived needs and can renew their productivity after completion.
Mechanism of the second generation
To remove energy from meat, the molecule adenosine triphosphate (ATP) is split into adenosine phosphate (ADP). As a result of this reaction one can see the energy that is used up for speed. Meat tissue gradually releases ATP molecules, which allows processing without clumping.
Since sourness is supplied to the meat promptly, it synthesizes ATP from glucose, which occurs during the reaction of carbon dioxide and water. If there is not enough sourness, the reaction proceeds continuously. As a result of the synthesis, a by-product is created - lactic acid (lactate), which accumulates and causes an increase in volume.
What is associated with the pain of sores?
Several reasons have been revealed to call out to Myazov:
- Replenishment of energy resources – reserves of carbohydrates, such as glycogen in meats.
- Accumulation of metabolic products in textiles.
- Impaired transmission of nerve impulses in the central nervous system and decreased nerve-muscle ligament.
Like navantazhenya flows into the development of meat volume
The more intensively the meat is processed, the faster it becomes boring.
Intensity can be of two types:
- The fluidity of the arms is high (for example, in a sprinter).
- It is very important to raise your muscles (in important athletics or powerlifting).
However, lighter, less intense exercise can be sustained by the body for many years. The butt of such robots is walking. In this case, energy is supplied to the meats by the aerobic system through the oxidation of fats by acids.
Vitomi m'yaziv
- Energetic second.
Our body has a number of mechanisms for energy synthesis:
- The phosphate mechanism of ATP synthesis is based on the obvious reserves of phosphates in meats. It quickly synthesizes ATP from ADP, vicoric acid, and high-energy creatine phosphate (CrP). Ale reserves of the KrF rise for only 8-10 seconds at maximum intensity.
- After creatine phosphate is stimulated, the synthesis of phosphates in meat begins to be converted into carbohydrates. Glucose is stored in meat tissue and liver as glycogen. People of varying levels of exercise have increased glycogen levels, but the average person needs 60-90 intense workouts. Energy from carbohydrates can be synthesized either with the participation of acid – aerobically, or without it – anaerobically.
After the depletion of carbohydrate reserves, the athlete switches to energy security only due to the breakdown of fats, in which case he loses the ability to exercise right at high intensity. At this point, there is a decrease in the fluidity and strength of the muscles.
- Fats can be disintegrated in the presence of sourness. If the meat fibers live without the fat cells, the stench cannot overcome the maximum strength of the meat. To protect the lungs, stench can persist even longer, since the body’s fat reserves are practically inexhaustible.
The energy level is reduced after 60-90 bouts of high-intensity training, which is associated with depleted glycogen reserves, weakness in the legs and arms, and it is difficult to keep busy for such minds. When you have enough energy, you can quickly restore the effectiveness of the meat system - sufficiently saturate the body with rich carbohydrates (sugar and glucose).
- Secondly, through the accumulation of metabolic products of speech.
However, with minor physical exertion, for example, when walking, the healing of the muscles can be caused by the loss of fat. With increased intensity of flows, the mechanism of carbohydrate breakdown is activated in energy exchange.
With further increases in intensity, the fluidity of oxidation of carbohydrates increases, and through the acidity, the breakdown of parts of glucose occurs anaerobically. When this occurs, lactic acid (lactate) is resolved, which accumulates in the meat tissue. Such processes often occur when an athlete, running a long distance race, sharply increases the pace on the finishing straight.
Accumulated lactate should be brought up to the second. It's painful to see. Due to the high concentration of lactic acid, the walls of the cells are damaged, which is also lost in the blood. High levels of lactate in meat tissue disrupt coordination abilities, lead to microtraumas and reduce the fluidity of speech exchange.
- Nerve-impulse vtoma.
This type of meat is due to a change in the process of transmitting impulses in the nerve-muscle junction. Due to the impossibility of maintaining high productivity of the nerve tissue for a long time, it decreases due to the influx of stress. If the intensity level is maintained at a high level for a long time, the nerve tissue is blocked and stops transmitting nerve impulses to the muscle.
Symptoms of myastomia
With this increase, the height and softness of the pulp decreases. The athlete begins to increasingly master the Vibuch work. The speed of the stroke and the height of the strokes decrease, the frequency and amplitude of the stroke change. Beware of decreased coordination, right-handed technique is destroyed.
This means that the fibers of white meats, which provide energy in carbohydrates, have ceased to absorb food and have become acidified due to the accumulation of lactic acid.
Possible inheritances and complexity
A high concentration of lactate leads to micro-fractures of fibers, which can cause injury. A high level of lactic acid reduces the level of creatine phosphate and reduces the fluidity of fat breakdown.
The muscles must be given enough time to develop; otherwise, overtraining may occur.
Signs of overtraining:
- It is a good idea to restore your heart rate to normal values after exercising and speed up your heart rate and become calm.
- A rapid onset followed, a decline in sports performance.
- Subject to appetite.
- Pain in the flesh, ligaments and swellings.
- Increased nervousness and a sense of anxiety.
- Sleeplessness.
- Sweating is increased.
As a result, interest in activities decreases, the risk of injury increases, and immunity decreases. To renew the body, it is necessary to sharply change the intensity of exercise by stretching 1-2 strokes.
How can I put my finger on it for this reason?
To restore muscle tone after intense exercise, the body needs 24 to 96 years of recovery.
To remove 95% of the lactic acid from meat to the body, you may need more than 1 year and 20 days of passive recovery. To speed up this process, you need to install a light robot. For example, a constant rush to prevent lactate from rising twice as fast as possible, and then passively.
This allows you to turn the output of the meat fiber and relax it.
If you have shown signs of overtraining, you should implement the following actions:
- Turn off Rozumov's voltage.
- Do some exercise, have fun, take a walk in the fresh air.
- Take a bath, go to the spa, get a massage.
- Keep the training intensity to at least 50% of the step pressure.
It is not possible to continue exercising at the same intensity as before. A passive repair is not recommended, since it will take more than two hours to renew.
Sports food and food for food
- Amino acids quickly regenerate the flesh during training, and therefore take part in all physiological processes. , increase the production of essential hormones and improve the vitality of the body.
- Creatine is a substance that plays a central role in the energy exchange of ATP and ADP. Creatine neutralizes the acids that cause lactic acid. This is consistent with scientific research and research.
- For rapid recovery, athletes need to consume a sufficient number of foods rich in vitamins and minerals, including: raw vegetables, fruits and greens.
- Fish fat contains polyunsaturated fatty acids omega-3, which contribute to the functioning of all systems of the body, starting with the brain and right up to the renewal of the joints.
Infusion of energy into the immune system
Physical challenges, infections and immunity are closely linked to each other. Moderate aerobic exercise stimulates the immune system, and vigorous exercise tends to depress it. Physical interventions can lead to damage to fabric and create fire hazards.
If the intensity of training is increased, 70% of the maximum capacity, their positive effect on the immune system will disappear completely.
Visnovok
Myazova is also a natural process that protects the muscle and nervous system from destruction. We understand that this is due to the depletion of living tissues, the accumulation of lactic acid and changes in the nerve-muscle ligaments. It’s important to start bodybuilding, listen to your gut, don’t overtrain, and maintain a sleep and eating routine. Only in this way can you achieve maximum training results.

Secondly This is called a temporary decrease in productivity of a cell, an organ or an entire organism, which occurs as a result of work and occurs after repair.
If rhythmic electrical stimuli are applied to the isolating meat for a long time, until the pressure rises, then its amplitude soon gradually changes until it reaches zero. Trimmed in this manner, the curve is called the curve vtomi.
As the amplitude of the shortness of time changes, the latent period of quickness increases and the thresholds of subdivision and chronaxia increase, which leads to a decrease in restlessness. These changes do not occur immediately after work, but after an hour, during which time there is an increase in the amplitude of individual short-term symptoms. This period is called the period of indoctrination. With further drying, a volume of meat fibers develops.
The decrease in the usefulness of meat isolated from the body when it is severely irritated is due to two main reasons: the first of them is that, under the hour, metabolic products of waste products (zocrema, lactic acid, phosphoric acid) quickly accumulate in the meat etc.), what suppress the flow on the fruitfulness of the meat. Some of these products, as well as potassium ions, diffuse from the fibers into the interstitial space and flow into the active membrane, generating action potentials.
If the isolating meat, premises at the Ringer farms, brings the waste of waste to the point of complete exhaustion, then it is enough to change the environment that washes it in order to restore the shortening of the meat.
Another reason for the development of isolated meat is the release of new energy reserves. With the treatment of isolated meat, there is a sharp change in glycogen reserves, as a result of which the processes of resynthesis of ATP and creatine phosphate are disrupted, which is necessary for this purpose.
The use of the nerve-muscle drug is due to such reasons. In case of severe nerve damage, the nerve-muscle transmission develops long before the muscle, and moreover, the nerve, through fatigue, wears out before awakening. It is explained that the supply of “prepared” mediator changes in nerve terminals during severe stimulation. The portion of acetylcholine that is seen at the synapses in response to the skin impulse changes and postsynaptic potentials decrease to subthreshold values.
In case of a trival subcutaneous nerve, it is recommended to reduce the sensitivity of the postsynaptic membrane of the meat fiber to acetylcholine. As a result, the value of the terminal plate potentials changes. If their amplitude falls below such a critical level, the loss of action potential in the meat fiber occurs. For these reasons, synapses are often formed, lower nerve fibers and tissues.
It can be seen that the nerve fibers show obvious inactivity. First up N.Y. Vvedensky showed that the nerve in the atmosphere preserves its strength until the awakening is carried out with a long period of continuous stimulation (about 8 years).
Vivid innocence The nerve is often stored due to the fact that the nerve expends very little energy when it is awakened. Once again, this process of resynthesis in the nerve can be affected by too little waste in wake-up situations, since the wake-up period lasts for many years.
Wasting of isolated skeletal meat with direct identification of a laboratory phenomenon. In natural minds, the tiredness of the rotary apparatus with a difficult job develops more complexly and lies in a large number of factors.
1. In the body, the meat continuously supplies blood, and, therefore, removes from it a large number of living substances (glucose, amino acids) and is released as metabolic products, which disrupt normal life. activity of meat fibers.
2. In the whole organism, there are not only processes in the flesh, but also processes that develop in the nervous system, which take part in the cervical roach activity.
So, for example, this is accompanied by a discoordination of the rocs, the awakening of rich meats, so as not to take the fate of the victorious robots.
Vtoma– due to the temporary decrease in productivity, the result is deep biochemical, functional, structural damage that occurs during the course of physical work, which manifests itself in the subjective sense of the person. Weary people are unable to maintain the necessary level of intensity and (or) brilliance (Viconnian techniques) of work or are tired of being able to continue it.
From a biological point of view, this is a dry reaction that causes an increase in physiological changes in the body, which may become unsafe for health and life.
The mechanisms of development of this are varied and primarily depend on the nature of the constructed work, its intensity and difficulty, and depend on the level of preparedness of the athlete. However, in a specific skin condition, the conductive mechanisms of fatigue may be seen, which lead to a decrease in productivity.
When different rights are violated, the reasons are not the same. A look at the main reasons for this connection between the two with basic concepts:
- Localization second, That is, seeing this wired system (or systems), functional changes in this system mean that it will now become the same.
- Mechanisms i.e., these specific changes in the activity of wired functional systems, which represent the development of the latter.
Three main systems are localized in
- regulatory systems - the central nervous system, the autonomic nervous system and the hormonal-humoral system;
- system of vegetative maintenance of meat activity - systems of digestion, blood and blood circulation, the formation of energy substrates in the liver;
- Vikonavcha system - rukhovy (peripheral nerve-muscle) apparatus.
Mechanisms
- Rozvitok funeral (foreign) galmuvannya;
- Impaired functions of autonomic and regulatory systems;
- The depletion of energy reserves and the waste of land;
- Development and accumulation of lactate in the body;
- Micro-augmentation of meats.
Rozvitok funeral (overseas) galmuvannya
When biochemical and functional damage occurs in the body under the hour of meat, afferent (sensitive) nerves reach the central nervous system Additional signals. When a significant depth of these damages is reached, a protective galvanization is formed in the cerebrum, which expands to the orchial centers, which innervate the skeletal muscles. As a result, motor neurons change the vibration of motor impulses, which results in a decrease in physical performance.
Subjectively, the protective galmuvaniya is perceived as almost like a second thought. This is also reduced due to the loss of emotions, caffeine and natural adaptogens. In the case of sedatives, including bromine preparations, protective galvanization occurs earlier, which leads to the reduction of efficiency.
Impaired functions of autonomic and regulatory systems
This may be associated with changes in the activity of the autonomic nervous system and problems with internal secretion. The role of the remaining ones is especially great for those who have rights (A. A. Viru). Changes in the activity of these systems can lead to disruption in the regulation of autonomic functions, energy supply of meat activity, etc.
With particularly stressful physical work, there may be a decrease in the function of the supra-neural glands. As a result, the presence of hormones such as adrenaline and corticosteroids in the blood changes, which are released in the body and become less responsive to the functioning of muscles.
Small 1. Hormones in the blood at 65% of MIC
The reason for the development may be a lot of changes in activity, overdose, dichotomy and cardiac-vascular systems that are responsible for the delivery of acid and energy substrates to working meats, as well as for the removal of metabolic products from them. The main consequence of such changes is a decrease in the oxygen transport capacity of the working person’s body.
Decreased functional liver activity It also supports the development of the latter, and during the course of meat work in the liver, such important processes as glycogenesis, beta-oxidation of fatty acids, ketogenesis, gluconeogenesis, which are directly responsible for the protection of meats, take place. energy sources: glucose and ketone bodies. Therefore, for sports practice, hepatoprotectors are used to reduce metabolic processes in the liver.

Extraction of energy reserves and waste of land
As you know, physical work is accompanied by great energy expenditures, so when carrying out physical activity, you will likely run out of energy. energy substrates. By this we mean that portion of carbohydrates, fats and amino acids that can provide energy during meat processing. With such energy sources, meat creatine phosphate is used, which can be used as a substitute for intensive meat work. meat and liver glycogen, part of fat reserves, which are found in fat depots, as well as amino acids, which begin to oxidize under extreme conditions. Energy reserves are important to maintain the required level of glucose in the blood during physical activity.

Small 5. Energy capacity of different parts
The removal of energy substrates leads to a decrease in ATP production and a decrease in the ATP/ADP balance. A decrease in the nervous system leads to disruption of the formation and transmission of nerve impulses, incl. supporting skeletal muscles. Such disruption of the functioning of the CP is one of the mechanisms for the development of the protective galvanization.
A decrease in the fluidity of ATP synthesis in the cells of skeletal muscles and myocardium disrupts the short-term function of myofibers, resulting in a decrease in the strength of the formed work.
To support energy resources during the final phase of work (cross-country races, marathons and other road cycling races), distance training is organized.
Ryasne potovidilennya During the period of exhaustive sports activities is accompanied by a significant loss of chlorides and a change in the proportion of ions of sodium, potassium and calcium, chlorine and phosphorus in the blood and body tissues, which itself leads to a decrease in power purposefulness.
Vtoma with trival work in high temperature drains and high moisture in the excessive middle part can result from overheating. This disrupts the functioning of the central nervous system and can lead to heatstroke (headache, blurred vision, and in severe cases, loss of energy).
The factor that contributes to the development of the second is the cooling of the body.
Development and accumulation of lactate in the body
Lactic acid is developed in the largest number of cells in the body when it reaches submaximal tension, which significantly affects the functioning of meat cells.
With increased acidity, the short-term production of proteins decreases, which is associated with meat activity. The activity of protein enzymes ATPase decreases, the activity of myosin and the activity of calcium ATPase (calcium pump) decreases. The power of membrane proteins changes, which implies an increase in the penetration of biological membranes.
Lactate causes the meat cells to swell, as a result of the presence of water in them, which reduces the short-term capacity of the meat.
It is transferred that the lactate binds part of the Ca ions and thereby destroys the process of speeding up and relaxing the muscles, which is especially noticeable in the Swedish authorities of the muscles.

Micro-auscultation of sores
The peripheral part can be understood as metabolic agents, and microorganisms of meat fibers in some parts of the strong soon.
Important! It is important to note that such micro-acuteness leads to post-workout myalgia - “cripaturia”.
Eccentric muscle contractions lead to greater expression of micro-cutting, less concentric or isometric.
Singing in micro-damaged meats with severe eccentric exercise (for example, running at long distances) can be contributed by other factors:
- exhaustion of resources,
- change calcium transport,
- that creation of active forms of acidity,
- lipid peroxide oxidation (LPO).
A small portion of O2 that enters the body through the air is converted into active forms called free radicals. Free radicals, with high chemical activity, cause the oxidation of proteins, lipids and nucleic acids.
The lipid sphere of biological membranes is most susceptible to oxidation. This oxidation is called lipid peroxide oxidation (LPO). Allow radical oxidation to induce acidosis and stress hormones until the fluid increases. Supermundane activation of SEX negatively infuses fleshy activity.
Thus, the penetration of membranes of nerve fibers and the sarcoplasmic reticulum of myocytes, which advances, facilitates the transmission of nerve impulses and reduces the short-term production of meat. Damage to the tissue tanks, which contain calcium ions, leads to disruption of the function of the calcium pump and a decrease in the relaxing powers of the muscles. When mitochondrial membranes are damaged, the effectiveness of tissue healing decreases.
