Physical activity does the body good, and there’s growing evidence that it
helps the brain too. Researchers in the Netherlands report that children who get
more exercise, whether at school or on their own, 26to have higher GPAs and
better scores on standardized tests. In a 27of 14 studies that looked at
physical activity and academic28, investigators found that the more children
moved, the better their grades were in school, 29in the basic subjects of math,
English and reading.
The data will certainly fuel the ongoing debate over whether physical
education classes should be cut as schools struggle to 30on smaller budgets. The
arguments against physical education have included concerns that gym time may be
taking away from study time. With standardized test scores in the U.S.31in
recent years, some administrators believe students need to spend more time in
the classroom instead of on the playground. But as these findings show, exercise
and academics may not be 32exclusive. Physical activity can improve blood 33to
the brain, fueling memory, attention and creativity, which are 34to learning.
And exercise releases hormones that can improve 35and relieve stress, which can
also help learning. So while it may seem as if kids are just exercising their
bodies when they’re running around, they may actually be exercising their brains
as well.
