Explain METABOLIC EQUIVALENTS (METs)
Metabolic equivalents (METs) are used commonly to express the intensity of physical activities.
A MET is the ratio of a person's working metabolic rate relative to the resting metabolic rate
1 MET is equal to 3.5mL/kg/min..
List the METs level that must be reached for an activity to be considered a sedentary behaviour and moderate intensity behaviour
Sedentary behaviours include activities that involve energy expenditure at the level of 1 - 1.5 METs.
Participation in an activity of moderate intensity would result in a MET level of 3-6
Explain Incidental Physical Activity
Incidental physical activity is less structured than planned activity. An example is using the stairs instead of the lift at a shopping centre.
Often the goal is not physical activity-the incidental activity occurs as a consequence of engaging in this behaviour.
