Educators are facing increased pressure to improve the academic performance of students. This increased emphasis on student accountability has led many school leaders to implement changes in the school day in order to maximize the time that students spend in academic pursuits. Frequently, this has resulted in the cutting or reducing of time spent in extra- and co-curricular activities, including recess and physical education. These changes have the potential to reduce the time children spend being physically active. Childhood health is also of great concern, and has recently received much attention in the popular media, including concern for obesity. Children are increasingly showing the development of lifestyle diseases such as Type-II diabetes and atherosclerosis, typically not seen until adulthood. These conditions can be brought about in part by low levels of physical activity and poor nutrition. The development and implementation of strategies to improve health and academic performance in school is important for ensuring the well-being and success of the children. In this article, the authors describe a program aimed at providing increased opportunities for physical activity and improved nutrition at school, along with the program's impact on several school performance and academic achievement variables.
