Regular physical exercises improve brain function in young people, according to the Internet edition for girls and women from 14 to 35 years old Pannochka. net These data run counter to the widespread claim that the brains of young people at the peak of their physical shape do not benefit from exercise, in contrast to the brains of middle-aged and elderly people.
A new study, published in the journal Psychophysiology, was conducted by Dr. Liana Machado of the University of Otago in New Zealand.
According to the researcher, the world has collected enough data on the positive effects of aerobic exercise on the brain of older people, but their impact on young people is poorly understood.
A new study revealed that young women who exercise regularly have a higher level of oxygen in the frontal lobe of the brain, and also cope better with complex mental tasks compared to peers who move little. The level of oxygen in the brain can be one of the most important factors determining cognitive functions - thinking, memory, training, attention, as well as motor skills and speech.
Dr. Machado says that the idea to conduct such a study came to her after her own observations of the progress of students who were in different physical forms. Working for many years in this direction, she could not help but associate physical exercises, the level of oxygen in the brain and cognitive indices. But devoted to this issue of research Machado did not find.
For their work, Dr. Machado and her staff recruited 52 university students between the ages of 18 and 30. Scientists asked them to undergo a series of cognitive tests, during which they measured the availability of oxygen in the frontal lobe of the brain. All participants talked about how often and how intensively they are doing.
The scientists used the method of near infrared spectroscopy (NIRS). When a certain area of ??the brain is active, there is a rapid change in the oxygen level in this area. The NIRS method allows recording the change in hemoglobin concentration, which is related to the oxygen level.
Dr. Machado called "surprising" the results of his research. She said: "This gives us evidence that regular exercise, at least 5 days a week, is one of the most effective ways to improve brain function in young people. Our data once again confirm that a sedentary lifestyle in young years can lead to health problems in the future ".
Regular exercises for the brain are more important than weight control?.
The team also found that the body mass index (BMI) is not a key factor for brain performance. Much more strongly affect the brain the regularity and intensity of your physical activity. According to researchers, even fast walking can benefit the young brain. If you do not have enough time for sports, then you can divide the training into several sessions for 10-15 minutes, for which it is easier to find time during the day. The main thing is to study.
Meanwhile, American pediatricians are already concerned that the lack of exercise affects the mental development of children. In the USA, as in many other developed Western countries, the level of physical activity of children has fallen sharply over the past 30 years. Do many children today spend time in the yard or on the football field? But how many regulars of social networks and online games! But health is laid down from childhood.
