Caffeine contains biological substances that serve as booster to increase metabolism and thus help the breakdown of fat burns in the body. This is possible because caffeine blocks the Adenosine , An inhibitory neurotransmitter, and thereby increase the levels of Dopamine Y Norepinephrine . In this way, the nervous system sends signals to the fat cells to give order of their decomposition.
In addition, caffeine helps increase levels of adrenalin (Epinephrine hormone). It runs throughout the body through the blood, sending signals to the fatty tissues for their decomposition.
There are several studies that reveal that caffeine is a potent accelerator of metabolism, that is, our body's ability to burn calories in a state of rest. It is estimated that consuming caffeine, can increase the metabolic rate between 3 and 11% on average.
This effect on the metabolic rate depends very much on the individual's constitution, since a thin person can see it increased by 29%, in the case of obese people, it will hardly exceed 10%.
However, this metabolic increase is effective in the short term, because as we adapt to their consumption, the body tolerates more of the effects of caffeine and they lose their ability.
Caffeine pills have a Diuretic effect , So it is necessary to drink plenty of water to avoid possible dehydration. This has positive effects if you follow the advice.

That is, a person who drinks a coffee will get more performance in an activity than one who does not take it.
In order to draw these conclusions, the speed of information processing, visuospatial capacity, manual dexterity, immediate memory and sustained attention of a group of university students of 18 years of age And 25 years.
This performance will be evident in the planning, organization and management of time, as researchers at Brigham and Women's Hospital in Boston (USA)
Although it was 'populist voice' among the scientific community that caffeine served as a stimulant for a Memory improvement , It was not until the year 2014, when Johns Hopkins University (USA) developed a study demonstrating this statement.
Published the study in the scientific journal Nature Neuroscience, The conclusions drawn are that caffeine has the ability to stimulate the central nervous system, detecting its potential for decreased forgetfulness for at least 24 hours.
Michael Yassa, coordinator of the study, argues that a consumption of caffeine helps maintain a healthy longevity, since it serves as a protector of the Cognitive impairment .
Are they suitable for training?
Numerous scientific studies support caffeine as a substance that strengthens performance in sport. This is because caffeine allows the muscle reserves of glucose Hold more and therefore delay the downfall in the athlete.
In a study published in The Journal of Nutrition, Health & Aging In 2014, drinking a couple of coffees before stepping into the gym would boost performance, improving performance on tasks such as push-ups, manual skills, or running-related activities.
The Headache Laboratory of the Harvard Medical School (USA) demonstrated over the past decade that caffeine is a potent inhibitor of pains such as migraine , But it also has the ability to alleviate some pain related to sports such as cramps or stiffness.
It is true that although no one doubts the stimulant benefits in the sportsman, if there is some controversy on whether caffeine can produce side effects.
