Title: ActiveBrains: Effects of an Exercise-based Randomized Controlled Trial on Cognition, Brain Structure and Brain Function in Overweight/Obese Preadolescent Children

Exclusion Criteria:

* Teens who are under age 14 will be excluded because:

  * They are not likely to be enrolled in high school, and
  * They are unlikely to have sufficient cognitive development to benefit from the proposed intervention
* Teens who are over age 16 will be excluded for two key reasons:

  * We believe that the cognitive development of and social expectations for older teens requires a more complex and flexible intervention than that proposed, and
  * Teens need to be available for 12 month follow-up sessions (our pilot studies indicated that this becomes less likely once teens are old enough to leave/graduate from high school, emancipate from parents, and/or leave home).
