Promoting physical activity is far more simple than providing kids with a physical education. This leads to common questions like "why is physical education so much more important?" or "what is the difference between physical activity and physical education?". Simply put, physical education helps develop physical literacy. Physical activity alone, does not. Using every gimmick under the sun to get people active provides a band-aid solution at attempting to put a long-term dent in rising physical inactivity levels across our population. In comparison, physical literacy provides a cure.
Physical education matters when it comes to improving academic performance in the classroom, not to mention the positive effects on both short-term and long-term health. If you are a science nerd like myself and want some reports containing hard evidence to support this statement, I recommend reading these reports published by the U.S. Department of Health & Human Services and UNICEF.
