movement in classroom

I am currently studying Early Childhood Education and want to pursue a career either working in a classroom or in a field where I can work with children regularly. Through my experience so far, I have noticed the variations of the layout of classrooms. This could be simply a result of the different types of teachers and how they like their classrooms to be set up, but I think that there is more to it than just that. I think that classrooms are being purposefully set up in a way to promote more motion and physical activity, especially in the classrooms of elementary ages. I have learned that one of the most beneficial ways that children learn is through physical activities. http://specialsections.suntimes.com/education/privateschools/136242...

My question is, what are more ways to incorporate movement in a classroom? Also, would there be the same benefits for older students or even adults if movement was more highly involved in their classrooms or work setting?
