importance of teacher\'s physical presence in class
‘Miracle-Gro for the Brain’
Exercise may have both a physiological and developmental impact on children’s brains. Physical mechanisms include:
Increased oxygen to the brain that may enhance its ability to learn
Alterations to neurotransmitters
Structural changes in the central nervous system
In fact, John Ratey, author of A User’s Guide to the Brain, calls exercise “Miracle-Gro for the brain” because of its role in stimulating nerve growth factors.
Studies suggest that regular physical activity supports healthy child development by improving memory, concentration, and positive outlook. For example, researchers found that children who had an opportunity to run for 15 to 45 minutes before class were less distracted and more attentive to schoolwork. These positive effects lasted two to four hours after their workouts.
The connection between learning and exercise seems to be especially strong for elementary school students. Given these findings, cutting back on physical education with the aim of improving academic performance, as some districts have done or may be considering, is likely to be counterproductive.
