The Sedentary Behaviour Research Network published International Recommendations for School-Related Sedentary Behaviours.

Recommendations are for children and youth attending school (typically 5–18 years of age) inclusive of gender, culture, nationality and socioeconomic status. These evidence-based recommendations provide guidance on ways to maximize the benefits and minimize the harms of school-related sedentary behaviours and are based on the best available evidence, expert consensus and stakeholder input. Anyone with an interest in student health and well-being can use these voluntary recommendations to counter sedentary behaviours—including students, educators, school administrators, policymakers, parents/guardians, caregivers, physicians and other healthcare providers.

Recommendations include breaking up school-related periods of extended sedentary behaviour with both scheduled and unscheduled movement breaks:

• At least once every 30 minutes for ages 5-11 years.
• At least once every hour for ages 12-18 years.
• Consider a variety of intensities and durations (e.g., standing, stretching breaks, moving to another classroom, active lessons, active breaks).
