The researchers said that two cups of drink is enough to enhance physical performance.
A group of American and Australian scientists set the optimal dose of coffee per day. It turned out that two cups is enough to enhance the physical performance of a person. This writes Lenta.ru.
During the study, researchers analyzed 300 scientific papers, which were attended by 4.8 thousand people.
As a result, it turned out that caffeine improves the results of sports training. This is due to the fact that it acts on the adenosine receptors. The latter are associated with adenosine, which plays the role of a chemical signal responsible for the feeling of fatigue. Caffeine competes with adenosine, eventually causing the opposite effect.
It is established that one cup contains 95-165 milligrams of caffeine. And improvements can be achieved with a dose of 3-6 milligrams per kilogram, and this is 210-420 for a person who weighs 70 kilograms. This is equivalent to two cups of coffee drunk.
