Structured physical activity: Activity that is developmentally appropriate and fun. Structured physical activity should include

  • daily planned physical activity that supports the development of age-appropriate motor skills, is engaging, and involves all children with minimal or no waiting; and
  • daily, fun physical activity that is vigorous (gets children “breathless” or breathing more deeply and more rapidly than during typical activities) for short bouts of time.

Sugar-sweetened beverages: Beverages to which sugar, typically high fructose corn syrup or sucrose (table sugar), has been added, including soft drinks, fruit drinks, sports drinks, tea and coffee drinks, energy drinks, and sweetened milk or milk alternatives.

Toddler: A child from 12 months up to 36 months of age.

Unstructured physical activity: Child-initiated physical activity that occurs as the child explores his or her environment. Unstructured activity should include

  • activities that respect and encourage children’s individual abilities and interests; and
  • teacher engagement with children, support for extending play, and gentle prompts and encouragement by teachers (when appropriate) to stay physically active.

Vigorous physical activity: Muscle-powered movement at a fast pace; examples are running, stair climbing, and cycling at a fast pace. Energy expenditure is at a rate of 7.0 metabolic equivalent of task or above.
