Study links cardiorespiratory fitness, thinner gray matter and better math skills in kids

EurekAlert! – Staff Writer

A new study reveals that 9- and 10-year-old children who are aerobically fit tend to have significantly thinner gray matter than their “low-fit” peers. Thinning of the outermost layer of brain cells in the cerebrum is associated with better mathematics performance…The study suggests, but does not prove, that cardiorespiratory fitness contributes to gray matter thinning – a normal process of child brain development. The study also offers the first evidence that fitness enhances math skills by aiding the development of brain structures that contribute to mathematics achievement.”(more)
