This study will determine the effectiveness of a free before-school physical activity program, BOKS (Build Our Kids' Success), in increasing objectively measured physical activity levels among children in elementary and middle school in 7 schools in Massachusetts. The study focuses on capturing valid and objective assessments of student-level physical activity during BOKS program time and assessing the impact of the BOKS program on overall daily physical activity levels using minute-by-minute physical activity level data among elementary aged students. Data is also collected to understand how increasing physical activity may impact students' sleep.
