Scientists have proven that there is a link between exercise and the brain
In the magazine "Trends in Neurosciences" published the results of a new study conducted by scientists at the University of Arizona (University of Arizona), USA.
 
The researchers found that the relationship between exercise and the brain is a product of the evolutionary development of a person, in particular his existence as a hunter-gatherer.
Anthropologist David Raichlen (David Raichlen) and psychologist Gene Alexander (Gene Alexander) - the authors of the new study, suggest explaining the positive impact of exercise on the brain using the following model. According to them, when a person moved to the lifestyle of a hunter-gatherer (about 2 million years ago), he began to perform tasks that were both physically and mentally difficult. So, physical activity and the work of the brain were connected. Researchers suggest that the human psyche has evolved to respond to an increase in the level of physical activity.

Exercise has a positive effect on the structure and functioning of the brain. Understanding the basics of this relationship can help scientists in the future to develop more effective exercise patterns and rational intervention for age-related impairment of cognitive abilities and neurodegenerative diseases, such as Alzheimer's disease.
It is noteworthy that the areas of the brain that work most intensively during complex physical activity (for example, when obtaining food) play a leading role in memory processes and are responsible for management activities (for example, they are involved in problem solving and planning). It is these areas of the brain that benefit during exercise, the authors of the new study say.
The aging process can be considered as part of the natural response to a decrease in physical activity, the scientists said. A sedentary lifestyle can have negative effects on mental abilities.
In the future, scientists plan to consider how different levels of physical activity and different types of exercise affect the brain. For example, a human study of a new environment may be particularly useful in this aspect, say the authors of a new study.
