Examples of sedentary, moderate and vigorous intensity physical activities

Activity levelAge-adjusted metabolic equivalent (MET)*Examples10
Sedentary1.0–1.5Lying, sitting, watching TV, playing video games
Moderate3.0–5.9Bike riding and playground activities. These activities will cause children to get warmer and breathe harder and their hearts to beat faster, but they should still be able to carry on a conversation
Vigorous6.0–8.9Fast running and swimming. These activities will cause children to get warmer, breathe much harder and their hearts to beat rapidly, making it more difficult to carry on a conversation
  • *MET, metabolic equivalent; 1 MET is defined as the energy expenditure of sitting quietly, equivalent in children to a resting oxygen intake of ∼6 mL/kg/min.11
