stimulates growth of new neurons and creates a 'healthy' dependence, with effects similar to cannabis
ROME - Who 'runs' every day is a favor to her body but also to his brain, promoting some specific capacity. This is demonstrated by a study published in the journal of the American Academy of Sciences (PNAS) conducted in "rat runners" by the team of Henriette van Praag of the National Institute on Aging, part of the U.S. National Institutes of Health, in Baltimore. Many studies both in humans and in animals have shown that exercise produces profound benefits for cognitive function, in children and young adults are found a strong positive association between physical activity and learning ability. Instead, the elderly exercise can slow the onset of memory defaillance those typical of the elderly.
EFFECT ON BRAIN - The race in particular, writing in PNAS, the authors of this study was shown to have profound effects on the brain in mice improves learning and memory and what results are related to structural changes and physiological hippocampal (middle memory), the stroke increases the production of neurotrophic factors (the "food" of the brain), increases the cerebral vasculature, neural plasticity. The race itself was even more miraculous effects. One study, for example, has shown that running is like smoking marijuana, but without side effects, it circulates psychoactive substances similar to principles in the plant, which act on the brain, giving feelings of euphoria.
A 'healthy addiction' - Scientists at the Georgia Institute of Technology and the University of Irvine have thus explained the phenomenon that is called from the seventies in America, "euphoria of the runner." It is the result of a mechanism put in place to protect the body from pain and to better withstand the stress during muscle activity. In fact, running the body produces high levels of anandamide, a molecule with the same properties as tetracannabinoidi issued by the marijuana on the nervous system. Now the experts have shown that adult mice that voluntarily run better able to overcome the spatial ability tests, to what is associated with neurogenesis, ie the birth of new neurons in strategic areas of the brain for learning and memory. In elderly mice but the effect is not known. Without the constraint of a card to be met at the gym, face to face with the green city, the race is then a simple and inexpensive to train not only the body but also the mind.
