There is a clear connection between physical, mental and physical activity, and therefore science has begun studying the positive effects of physical exercise and brain function.
At first it was thought that the positive effects were caused by blood flow increases significantly when you perform physical activity. Since brain cells oxygen and nutrients better and as a consequence are healthier.
However, although this is an important point, exercise varied effects on the brain and which are not only caused by increased nutrient supply.
Thus, besides the intellectual activity that is important to maintain that ability as you age, exercise is too, as it has proved ideal for protecting the body against diseases called neurodegenerative diseases.
Exercise is an excellent protector of the brain to the attacks it suffered over life, both external and internal, therefore, it becomes evident that a sedentary lifestyle becomes a risk factor for neurodegenerative diseases.
However, it is clear that when reference is made to exercise, you are not talking about being an athlete, but leaving aside physical inactivity and implemented, and a few miles a day briskly made to make all the difference.
The human body is designed to make physical activity constant for many hours, a fact that for the man of today can be considered very high.
But it should be noted that what has changed are the habits of man and their physiology is still the same, and must then understand that the body needs physical activity to pursue and maintain a set of core functions including health of neurons.
On the other hand, mobilizing the body while performing physical exercise generates a widespread brain activity as well as muscle groups move in a coordinated manner, there are also other phenomena such as increased blood flow, glucose uptake, heart rate, respiration, etc., all regulated by various nerve centers are located in different areas of the brain. Therefore, the active physical exercise these broad areas of the brain.
When physical activity is coupled with the movement of the muscles needed to carry out the exercise and the brain is responsible for coordinating all bodily functions which are essential for those muscles to function properly.
Therefore, the moderate physical exercise is highly beneficial for the brain to stay healthy, and prevent neurodegenerative diseases.
Regular physical activity keeps the necessary input of nutrients to the brain and is involved in other brain processes, optimizing the functional efficiency of neurons.
