This WSJ article, written by a teacher, considers 'Why students shouldn’t be forced to spend so much time sitting at desks in class?'.

What are the effects of adding more physical activity to the academic classroom? Mark Benden, director of the Ergonomics Center at Texas A&M, has dozens of schools using pilot programs to make classrooms more active. His research shows many benefits: There has been a decrease in ADHD medication among the students in his classrooms; body mass index among overweight students in active classrooms showed significant decreases. Executive function and working memory showed significant improvement, leading to improved academic achievement.
Increase Movement - Healthier Students - Improved Cognition.
