Want to know why we believe in CrossFit Kids like we do? It's more than physical activity to burn off the excess energy that drives all of us adults batty (we're really just jealous).
Science Daily tells the mainstream media what we've believed all along: Fit kids have better brain development. Thats why math is easier after recess.
Researchers have found an association between physical fitness and the brain in 9- and 10-year-old children: Those who are more fit tend to have a bigger hippocampus and perform better on a test of memory than their less-fit peers.
The study focused on the hippocampus, a structure tucked deep in the brain, because it is known to be important in learning and memory. Previous studies in older adults and in animals have shown that exercise can increase the size of the hippocampus. A bigger hippocampus is associated with better performance on spatial reasoning and other cognitive tasks.
