Background: Recess is an integral part of a comprehensive school physical activity program. Immediately prior to the pandemic, state legislation doubled the amount of required recess, creating an opportunity to better understand how policies and practices influence recess. Purpose: To describe changes to recess due to COVID-19 and extended recess legislation and to quantify student physical activity during recess following these changes. Methods: This mixed-method study was conducted in Spring 2021 in four elementary schools. Recess physical activity was measured using waist-worn accelerometers, recess was observed, and researchers conducted interviews with teachers and principals. Results: Females spent 41.7% (95%CI: 38.2, 44.5) and males spent 47.9% (95%CI: 44.6, 51.2) of recess in accelerometer-measured moderate-to-vigorous physical activity (n = 164). Participants (n = 13) discussed increased supervision, classroom separation on the playground, and benefits of extended recess. Discussion: States should consider extending recess requirements but need to consider options for scheduling and indoor recess. Recess continues to be a key physical activity opportunity during school. Translation to Health Education Practice: Health Educators considering changes to recess policies and practices may want to consider scheduling of recess including class integration, options for indoor recess, and professional development for recess supervision to help maximize the benefits of recess.
