Physical Fitness and White-Matter Tracts in Children
Frontiers in Neuroscience published research looking at the diffusion MRIs of 24 nine and 10-year-old children to determine an association between aerobic fitness and the brain. The study showed that children who are more aerobically fit have more fibrous and compact white-matter tracts in their brains than children who are less fit.
More specifically, the researchers found that significant fitness-related differences in the integrity of several white-matter tracts in the brain, including the corpus callosum (connects the brain’s left and right hemispheres), the superior longitudinal fasciculus (pair of structures that connect the frontal and parietal lobes) and the superior corona radiata (connect the cerebral cortex to the brain stem). These white matters tracts all play a role in attention and memory.
