Experiments and observations indicate that any kind of physical activity for a child has educational benefits including enhanced attention.
There’s a great new book called “Educational Neuroscience: Development Across the Life Span” which is:
“The first volume to bring together the latest knowledge on the development of educational neuroscience from a life-span perspective, this important text offers state of the art, authoritative research findings in educational neuroscience before providing evidence-based recommendations for classroom practice.”
One key take away is:
“Twenty minutes of moderate exercise improved planning but not attention in 9-10 year olds. But twelve minutes of intensive exercise such are running on a track boosted attention.”
