Free Caffeine SVG Files

Caffeine SVG is an alkaloid, a central nervous system stimulant with a wide range of other physiological effects, and belongs to the methylxanthin group found in plants such as coffee, tea (caffeine extracted from tea is often called theine), mate (caffeine extracted from it, sometimes called mate), guarana, cola, and many others.

For pharmacological purposes, it is synthesized and extracted from plants. Contained in energy drinks, often found in sports nutrition, almost all fat incinerators, many pre-training complexes.

Caffeine effects

Most Caffeine SVG studies have focused exclusively on sports that require increased endurance. Their main conclusion is that caffeine helps most of these athletes to achieve better sports results. There are three versions that explain this reaction. The first one was initially considered the most plausible and is related to the ability of caffeine to stimulate fat burning with energy generation. Caffeine contributes to the production of adrenaline, a hormone that accelerates the entry of fatty acids into the bloodstream and is a CNS stimulant. During initial exercise, muscles use fatty acids available for energy production, keeping muscle glycogen reserves intact. Some scientific studies have confirmed this theory.

The second version is that caffeine can directly affect skeletal muscles by altering key enzymes or systems that regulate the process of carbohydrate degradation within cells. But the study of this theory did not reveal unambiguous results and was not completed.

The third version may actually be the key to understanding how caffeine makes you feel that you have done less work than you actually have done. According to this version, this is because caffeine, due to its direct effect on the central nervous system, can provide a psychological effect, making athletes feel that they are not working as hard, or somehow maximize the strength of muscle contractions. We now know that caffeine does not penetrate the hemato-encephalic barrier and interfere with the action of adenosine, the neurotransmitter that causes drowsiness by slowing down the activity of nerve cells. Caffeine is structurally similar to adenosine and can bind to the adenosine receptors on the brain cells. But caffeine does not have the same effect as adenosine, it does not slow down nerve cell activity. Instead, it stimulates the production of adrenaline, a hormone that improves health during exercise. This is currently the predominant version, as confirmed by scientific research.

Scientists at the Institute for Scientific Information on Coffee (ISIC) have concluded that the consumption of three to five cups of coffee a day prevents the formation of beta-amyloid plaques in the brain, which are associated with the progression of Alzheimer’s disease and dementia. It was found that the two main ingredients of coffee, caffeine and polyphenols, have a positive effect on memory and cognitive function, which together reduce inflammation and stop the destruction of brain cells, especially in the cortical and hippocampal regions. In another study, it was noted that coffee lovers live longer.

U.S. scientists have found that caffeine can block changes in the brain associated with cocaine addiction. However, the studies were conducted on rats, so confirmation of the positive result is required on other experimental models.
