So here's my question. If scientists like John Medina say that we learn better when we are physically fit and exercise regularly, why is physical education a low priority in schools? Why aren't we running massive research to prove or disprove this concept? Seems to me if this were true, it wouldn't take a whole lot of extra money to build more activity into each school day.
One of the questions that comes up for me when I hear that exercise improves cognition is that from my own experience as a teacher this doesn't hold true. My best students haven't always been athletes or even athletic. Some of my worst students have been star athletes. And vice-versa. I've never noticed a pattern?
Anyway, here is a nice interview with Dr. Medina where some of the basics from his book Brain Rules are covered.
