During intense sports, the brain switches to an alternative source of energy, that is, instead of glucose, it begins to burn lactic acid, which is formed in the muscles during exercise, found together Danish and Dutch scientists.

Glucose is a universal source of energy in the human body, the main consumer of which is the brain. Therefore depriving the brain of glucose leads to a loss of consciousness, according to the Internet edition for girls and women from 14 to 35 years old Pannochka. Net Researchers conducted an experiment in which the level of various substances in the blood of participants was measured during intense physical exertion. It turned out that the blood leaving the brain contains much less lactic acid than the incoming blood.

Moreover, the results of the study showed that the brain does not accumulate lactic acid, but uses it as an alternative energy source. And since the physical load leads to a significant expenditure of glucose by the muscles, its level in the blood falls. That is why, perhaps, and there is a switching of the brain to the consumption of lactic acid. Thus, we receive brain feeding during intense physical exertion, which allows the brain to work constantly, experts say..
