Neurophysiologists from Canada conducted a series of unusual experiments in rats that showed that charging in adolescence really improves the work of long-term and short-term memory in the elderly, according to an article published in the journal eNeuro.

In recent years, several groups of researchers have found that intense exercise and exercise significantly improve brain function. For example, in 2008, Australian scientists found that 50-minute walks markedly improved memory and concentration in the elderly, and in 2015 their Italian counterparts showed that physical exercises help nerve cells form new connections with other neurons in trauma or the development of new ones skills.

All attempts to "grope" the cause of such improvements in the work of the brain ended in failure. For example, scientists repeatedly found a link between the increase in the size of the hippocampus during training and the improvement of memory in children and the elderly, but not in adults whose memory also improved greatly after charging or exercising on exercise bikes.

Martin Voitovich from the University of Toronto (Canada) and his colleagues proved that something similar happens among rodents, observing the work of the brain of two groups of rats, half of which led a usual "sedentary" way of life, while others regularly "twisted the wheel" days of one's life.

These experiments pointed to two curious things: they confirmed that doing sports really improves short-term memory immediately after physical exertion, and indicated that charging improves memory in the long run.

In particular, only six weeks of intensive exercises in "childhood" was enough to noticeably improve the work of animal memory in advanced years, so that they much better remembered the position of the exit from the maze and found it faster in unfamiliar surroundings.

As the scientists note, this improvement in memory was, apparently, due to the fact that high physical loads stimulated the formation of new connections between the cells of the hippocampus, the brain memory center, and forced the "adult" stem cells living in it to become full neurons and increase their number and density.

Similar results of experiments, according to scientists say that charging and other forms of physical activity can significantly reduce the likelihood of developing Alzheimer's and other neurodegenerative diseases associated with mass death of nerve cells.
