6 - Brain
On the other hand, the brain benefits from an
increase in blood flow. Immediately, the brain cells will begin to
function at a higher level. You will feel more alert and alert during
exercise and more focused afterwards. When you train regularly, the
brain gets used to this frequent increase in blood and adapts by
activating or deactivating certain genes. Many of these changes
stimulate brain cell function and protect against diseases such as
Alzheimer's disease, Parkinson's disease and general age-related brain
aging.
Exercise also triggers an increase in chemical messengers in the
brain called neurotransmitters, which include endorphins, often cited as
the cause of the mythical "feeling of happiness and pleasure" after
training. The brain also releases neurotransmitters like dopamine and
glutamate, to allow the movement of arms and legs for example, as well
as gamma-aminobutyric acid or GABA, a neurotransmitter that slows things
down, to keep you moving in a harmonious and controlled way. You will
also feel better with an increase in serotonin, another neurotransmitter
well known for its role in mood and depression.
