Abstract
BackgroundPhysical activity (PA) is critical to preventing childhood obesity and contributes to children’s overall physical and cognitive health, yet fewer than half of all children achieve the recommended 60 min per day of moderate-to-vigorous physical activity (MVPA). Schools are an ideal setting to meeting PA guidelines, but competing demands and limited resources have impacted PA opportunities. The Fueling Learning through Exercise (FLEX) Study is a randomized controlled trial that will evaluate the impact of two innovative school-based PA programs on children’s MVPA, cognitive function, and academic outcomes.MethodsTwenty-four public elementary schools from low-income, ethnically diverse communities around Massachusetts were recruited and randomized to receive either 100 Mile Club® (walking/running program) or Just Move™ (classroom-based PA program) intervention, or control. Schoolchildren (grades 3–4, approximately 50 per school) were recruited to participate in evaluation. Primary outcome measures include PA via 7-day accelerometry (Actigraph GT3X+ and wGT3X-BT), cognitive assessments, and academic achievement via state standardized test scores. Additional measures include height and weight, surveys assessing psycho-social factors related to PA, and dietary intake. School-level surveys assess PA infrastructure and resources and intervention implementation. Data are collected at baseline, mid-point (5–6 months post-baseline), and post-intervention (approximately 1.5 years post-baseline). Demographic data were collected by parents/caregivers at baseline. Mixed-effect models will test the short- and long-term effects of both programs on minutes spent in MVPA, as well as secondary outcomes including cognitive and academic outcomes.DiscussionThe FLEX study will evaluate strategies for increasing children’s MVPA through two innovative, low-cost, school-based PA programs as well as their impact on children’s cognitive functioning and academic success. Demonstration of a relationship between school-based MVPA with neutral or improved, rather than diminished, academic outcomes in a naturalistic environment has the potential to positively influence investment in school PA programs and initiatives.Trial registrationClinicalTrials.gov Identifier: NCT02810834.

Highlights
Physical activity (PA) is critical to preventing childhood obesity and contributes to children’s overall physical and cognitive health, yet fewer than half of all children achieve the recommended 60 min per day of moderate-to-vigorous physical activity (MVPA)
The Fueling Learning through Exercise (FLEX) Study is a randomized controlled trial that seeks to evaluate the impact of two innovative school-based PA programs on MVPA, and cognitive and academic outcomes over time among 3rd-5th grade children in underserved schools in northeastern United States
The Fueling Learning through Exercise (FLEX) Study will contribute to the evidence base on strategies for increasing children’s engagement in PA at school by using objective measures of physical activity to evaluate the impact of two innovative, low-cost, school-based PA programs on children’s PA as well as on their cognitive functioning and academic success
Summary
Physical activity (PA) is critical to preventing childhood obesity and contributes to children’s overall physical and cognitive health, yet fewer than half of all children achieve the recommended 60 min per day of moderate-to-vigorous physical activity (MVPA). Experts have called for a “whole school” approach to increasing children’s PA levels [14] in which recess, in-class PA breaks, before- and after-school programs, and integration of PA with academic curricula combine to create healthy school environments. Taken together, this comprehensive approach can increase time children spend engaging in MVPA to meet the recommendation of 60 min per day, 30 of which should be accrued during school hours
