the physical activety for the children

an american modern study that the practice of big children with little movement exercises regularly improves their ability to think and plan 
The study proved that physical exercise are associated with increased activity inside parts of the brain that related to the complex process of thinking and self-control.
The researcher Catherine Davis, Mental Health Specialist at the Georgia Institute of Immunology;said: "This confirms that the intense stillness that characterizes of most obese children affects their abilities and achievements."
ANDShe added that scientists have been convinced of the importance of physical exercise for children, but they do not have good evidence confirms that the practice of sport for children in school increases academic achievement. Although this study focused on overweight children, however, Davis believes that the findings also apply to normal-weight children.
AND Dr. Davies Believes  that: these positive changes in the mental capacity of children is the result of the interaction of biological and environmental factors.
and she adds that: the laboratory have proven that tests and the presence of growth factor nervous in rat experiments practiced physical activity overload, which may include some brain cells and further communication between them, but there are also some social and environmental factors that affect faster with the movement of the person."
 and Davis sees the importance of physical exercise to become an essential part of everyday life for our children, especially with the increasing rates of obesity among children in the world in general, and America in particular, where obese children represents nearly one-third.
and she said that "Parents should make sure their children awarded a balanced life, not only in their studies but also in learning how to care for their bodies as well."
The exercise program focused on fun and safety of more competition and skills, and also included games Alholahub running and rope skipping, researchers have recorded an increase in the pulse rates of children by 79%, which refers to the activity plus.
A research team of this study by choosing a sample of children 171 children randomly who are overweight between the ages of 7 and 11 years old. They then Division into two groups: the first underwent intensive exercises for periods ranging between 20 and 40 minutes after the school day and the second group did not practice any physical activity is a plus.
and the rays proved that:children who practiced sports increased their activity in the brain region known as area executive functions (which are connected to control self-planning and conclusion and abstract thinking), as well as the bark of the frontal lobe of the brain, which is linked to thinking processes and complex social behavior right, indicating that the more children increased their physical activity results of IQ tests have, but recorded an improvement in children's mathematical skills, but not in their ability to read.
and Thamantha Heller attached that, an expert psychology and nutrition to the study, saying: "Take a group of children and put them in the open air and give them some balls and rope jumping and chalk drawing on the he ground and leave them, you find them conducting and jumping and playing in a short time, and you will feel afterwards how much they are happy and more energy and intelligence. Know all over the importance of exercise for the health of the mind and body functions and when we deny a child his nature and natural need to play and let him spend long hours in front of the TV and the computer becomes the people Lethargic and  bad mood, and these children are more likely to be overweight and poor academic performance. "
and She adds: "in order to enjoy the children ofhealth and intelligence we have to encourage them to exercise on a regular basis and provide them with the appropriate time and place, we have to shut the television, computer and mobile phone and make them spend their time in the exercise of activities of natural play and run."
