Add a little nurturing too and see what that can do....
Recent studies of the effects of exercise on kids' brains reveal some amazing, clear evidence of the importance of working out. In a 2010 Illinois study, 9- and 10-year-olds exercised on a treadmill, and were classified into high, low, and medium fitness groups, depending on their performance. The most fit kids performed best on a test that was administered after the treadmill session. Other research has come up with similar results before, but this study took it one step further. The kids' brains were then scanned with magnetic resonance imaging (MRI). It turned out that the kids who were in the best condition had measurable physical differences in their brains. The hippocampus, which coordinates learning and memory, was larger in the kids in the fittest group. So were their basal ganglia, which govern ''executive control,'' the ability to make decisions and coordinate your thoughts and actions. They were all similar in socioeconomic level and background, so researchers are confident it was exercise that accounted for the differences in test performance.
Aerobic exercise releases a factor in the brain that protects brain cells, helps them make more connections to other brain cells, and even fosters the creation of new brain cells -- an action many people thought impossible just 25 years ago. It is called brain-derived neurotrophic factor (BDNF). The proof of its effects is exciting to brain researchers, who think exercise could hold the key to battling ADHD, depression, dementia and a whole array of conditions."
