School recess offers children physical activity, but most do not meet daily recommendations. Boys were more active than girls during recess, contributing valuable minutes toward daily physical activity goals.

Area of Science:

  • Pediatric physical activity
  • School health promotion
  • Childhood obesity prevention

Background:

  • Physical activity guidelines recommend 60 minutes of moderate-to-vigorous physical activity (MVPA) daily for children.
  • School recess is a key opportunity for children's physical activity during the school day.
  • Limited research exists on children's recess activity levels and their contribution to daily recommendations.

Purpose of the Study:

  • To quantify children's physical activity levels during school recess.
  • To determine the contribution of recess to daily physical activity recommendations.
  • To assess the intensity of physical activity during recess.

Main Methods:

  • 116 boys and 112 girls (aged 5-10 years) from 23 schools participated.

  • Physical activity was measured using uniaxial accelerometers during three recess breaks.
  • Percentage of time in moderate, high, and very high intensity activity was calculated.

    • Main Results:

    • Boys engaged in significantly more moderate, high, and very high intensity activity than girls.
    • Boys spent 32.9% of recess in physical activity, while girls spent 23%.
    • Children did not achieve 50% of recess time in physical activity.

    Conclusions:

    • Recess contributed approximately 28 minutes for boys and 21.5 minutes for girls toward daily physical activity goals.
    • Physical activity intensities during recess were generally low.
    • Interventions to increase children's physical activity during recess are needed.
