There are several theories for why exercise is beneficial for brain function:
- Increased blood flow to the brain, which helps feed the brain with nutrients such as oxygen and glucose
- An increased level of endorphins lowers levels of stress and anxiety
- Improved growth factors that spark learning by increasing the number of brain cells in the hippocampus - the area of the brain that is essential for memory and learning
A study from the University of Illinois found that students performed better on reading comprehension, math and spelling when they had a 20-minute period of physical activity immediately preceding the test.
It may be easy to think that the physical activity a student participates in at school is enough to improve grades, but adding in some extra activities won't hurt. The American College of Sports Medicine (ACSM) recommends finding family activities to participate in as well as encouraging youth to find an activity that they enjoy. By promoting fun physical activity, youth may not only benefit from increased academic potential, they have a greater chance of sustaining healthy lifestyle habits into adulthood.
