Movement changes the brain

Humans are born to move, because human beings are inseparable from the evolution of primitive people to modern people. Scientific research shows that exercise can make people smarter, exercise can make people happier, that is, exercise can change people's brain.

The human brain evolved in sports

Love sports is our nature, which is determined by the genes inherited by the ancestors. Before the era of wise people from 200,000 years ago, everyone was hunting collectors before the agricultural revolution in 10,000 years ago. At that time, the life characteristics were: the violent activities were rest for a few days, and people lived in a day. In order to survive for a long time, they must use wisdom to find and store food. The relevance between food, physical activity and learning has become a human brain loop system. As an eating animal, running and exercise is human and born instinct, long journey to collect food and hunting is human survival skills.

Some scientists believe that human brains have been prioritized, it is likely to be by-products of the exercise process. The State University of New York has studied the relationship between the exercise capacity and brain capacity of different animals. The higher the amount of new metabolic rates, the greater the proportion of the body. Humanity is a recognized king of mammal, our ancestors run unhappy, purely on excellent endurance arrest prey. After a long evolution, our ancestors gradually adapted to this changing environment, and the thoughts of the thoughts were evolved from the tempering of sports skills.

Why does this happen? A significant reason is that neurological activities need to consume a lot of energy, while the exercise can promote blood circulation, improve the oxygen supply capacity of capillaries, and ensure that the super brain can have sufficient energy. But another reason seems to be more critical, research showing that motion can promote a variety of neurogeneous factors secreted in nervous systems, including insulin-like factors (IGF-1) and brain nerve growth factor (BDNF). These growth factors can not only accelerate the split velocity of neuronal cells, but also promote neurocytes to create more linkages, which ultimately leads to the improvement of mental power.

Can exercise really smarter?

Many studies in the near future show that often exercise can improve memory and thinking. An interesting new study has put forward such problems: physical exercise is the benefit of improving cognitive ability, is it true or psychological? If we believe that you will be "smarter" after exercise, will our brain do not make a corresponding response? This question is crucial for those who want to keep their minds in their lives in their lives.

However, it is difficult to study this problem. For physical exercise, there is no invalidated control agent, and there is no way to let the subject know that he is moving. They know that there is no walk or cycling.

Therefore, scientists think of a smart way to go back. They decided to put the focus: Subjects expect that exercise will affect thinking. If their expectations are consistent with the actual benefits, then at least some benefits are likely to stem from psychological effects, not the results of exercise.

The scientists recruited 171 people through an online survey system, requiring half of the volunteers to assess, if three stretching exercises were performed in a week, how to improve their thinking, such as memory and a common ability. Another group of volunteers asked the same problem, but the exercise project was replaced with regular walking.

In real experiments, the stretching movement basically does not have much impact on cognitive ability. On the other hand, walking shows a significant improvement of thinking. However, in this experiment, the subject's idea is just the opposite. They estimate that the tensile project is more beneficial to the brain. It is measured by 1 to 6, and the volunteers believe that the average level of potential improvement of mild stretching on cognition is 3. They have a lower assessment of walking.

The interpretation of scientists is that since the subject believes that the tensile movement is more beneficial than walking, the actual result is to improve the brain than the drawing movement. This means that physical exercise is beneficial to the brain, it does not imagine, it does happen in our brain.

Scientists believe that these findings are sufficient to prove that exercise will really change the brain, perhaps in this process, may also improve thinking skills. This conclusion should be able to encourage scientists to further explore: How does the exercise have restructed our brain at the molecular weight?

Sports can secrete "happy"
