The brain is capable of change, alternative sources of energy during exercise

During intense exercise, the brain switches to the alternative energy source, ie, researchers instead of glucose, it starts to burn lactic acid that is produced in the muscles during exercise, gathered Danish and Dutch. Glucose is a universal source of energy in the body, which is the main consumer of the brain. Therefore brain glucose deprivation leads to loss of consciousness. The researchers conducted an experiment that measured the levels of various substances in the blood of participants during intense exercise. It was found that the blood from the brain much less lactic acid are used as in it comprises. In addition, the study showed that the brain does not accumulate lactic acid and use it as an alternative energy source. And movement leads to a significant consumption of glucose by muscles, the level in the blood falls. That is why, perhaps, there is a shift of the brain on the consumption of lactic acid. So we have to get the make-up of the brain during intense exercise, the brain has to work all the time, say experts.
