Energy is the basis of life. In the body it appears as a result of digestive processes. In normal conditions, the distribution of the resources received.
A large amount of energy is spent on brain and internal organs. The remaining part is postponed in the form of glycogen - the main reserve of glucose, which on demand is immediately spent on the necessary needs. The surplus of energy reserves is deposited in the adipose tissue, and from which ATP molecules are problematic.
Energy drinks are used to use the closest reserves, spending them at their own discretion. In drinks, there are no prohibited substances, in fact, this is a trap. The combination of different ingredients in different proportions gives a different effect.
It should be noted that the reception of even home-made energy drinks does not give all consumers an encouraging effect. About 10% of people, on the contrary, experience a decline in strength, become sluggish, sleepy. The difference in effects is explained not only by the composition of drinks, but also by the body.
The standard mechanisms of action give rise to failure, resulting in paradoxical reactions. Proponents of the reception of "energy" say that the cheerful substances that are part of them are allowed everywhere. Moreover, there are scientific studies confirming their correctness. And yet, most doctors talk about the dangers of energy drinks, because there is a sufficient number of contraindications to receive them.
Moreover, "energy" is included in the list of banned drugs for athletes three days before the start of the competition. The presence in the body of some components gives a positive reaction during doping control.
Composition of energy drinks
To date, in the world produced dozens of types of stimulant beverages, in terms of composition they almost do not differ.
- Caffeine - the main component;
- Normal sugar: a mixture of glucose and sucrose;
- Vitamins of group "В";
Differences in the composition of energy drinks are insignificant: one of the items in the last lines of the list is missing or other ones that do not significantly affect the quality of the product are added.
Absolutely all components are listed on the labels - the rules of trade are fulfilled in full. However, for consumers, the list (even with indication of dosages) does not give anything. We will analyze each element and its mechanism of action on the human body.
Mechanism of action and damage to energy drinks
Caffeine Refers to psychostimulants, the chemical formula is close to amphitamins, but its effect is limited to the excitation of the central nervous system, without stimulating the center of satisfaction. Therefore, caffeine can not be considered a narcotic drug, and the dependence - caffeineemia - has only a psychological basis.
Caffeine excitation of the central nervous system occurs at the level of the vascular and motor center and at the level of the synapse of the vascular walls - they narrow. So arterial pressure increases. The influx of blood into the brain disrupts mental processes and stimulates neuromuscular transmission.
Guarana - a natural psychostimulant. Contains caffeine and a lot of organic acids, which facilitate rapid contact with the nervous tissue. Energy drinks containing guarana, have a greater effect on the brain, so a person experiences an instantaneous influx of forces.
Glucose In pure form for brain cells, so that they receive additional energy for the management of organs that increase the efficiency of work.
Saccharose Used to nourish muscle tissue.
Theobromine Prolongs the effect of caffeine several times, because the chemical composition almost repeats its structure. Performs a catalyst function, occupying receptors that perceive caffeine.
Glucuronolactone - a chemical compound formed in the human body due to the decomposition of glucose molecules. In energy drinks, its content exceeds the physiological in 300-500 times. This chemical element displaces its own glucuronolactone, as a result, the central nervous system receives a signal that prompts the further disintegration of glucose stocks, the amount of which in a liquid that is clearly not enough. The body mobilizes its own reserves, working on wear.
Vitamins of group "В" Stimulate nerve endings and vascular walls, fulfilling "orders" of caffeine.
D-ribose - a chain of sugars that are part of the RNA and ATP. When the concentration of D-ribose exceeds the physiological level several times, the increased decomposition of ATP begins to generate additional energy.
L-carnitine - also produced in the body to accelerate the breakdown of brown fat, which is used in extreme, stressful situations. The body temperature rises, metabolism intensifies, the body fights for survival.
Thus, energy drinks provoke a stressful reaction in which all available human forces operate on the verge.
Ginseng, Probably the most harmless element. However, its concentration is too high. It provides long insomnia, anxiety and enhances vascular reactions aimed at raising the blood pressure.
The carbon dioxide content of the energy drinks degrades the damage to energy drinks, which immediately falls into active cations, which are the conductors of all substances directly in the bloodstream, passing the stage of treatment with gastric juice.
Considering the mechanism of action of substances that form part of energy drinks, one can come to the conclusion that they are not sources of extreme ability to work, and force the body to use all available reserves. That is why some people feel more cheerful after such a shake, and those who do not have their own reserves have the opposite effect - a complete decline in strength.
Home energy drinks
And yet, in spite of the fact that the exchange of substances is harmful, in some situations people are in urgent need of stimulants. Sometimes their use becomes a habit and family ritual, as in the English fief-o-block - afternoon tea. Tea, especially green, also refers to stimulating liquids. It induces the central nervous system to the planned actions without changing the program, as energy drinks do, mobilizing the person to work on the limit of their own capabilities.
After eating, for example, tea affects the synapse of the nervous system responsible for digestion of food. All known home-made energy drinks in high doses are able to change the metabolism, so enjoying the use of strong tea, coffee and cocoa is also not recommended, as well as their industrial analogues.
Vigilance in debt always requires high returns.
