Scope
The metabolic rate, as a conversion of chemical into mechanical and thermal energy, measures the energetic cost of muscular load and gives a numerical index of activity. Metabolic rate is an important determinant of the comfort or the strain resulting from exposure to a thermal environment. In particular, in hot climates, the high levels of metabolic heat production associated with muscular work aggravate heat stress, as large amounts of heat need to be dissipated, mostly by sweat evaporation.
This International Standard specifies different methods for the determination of metabolic rate in the context of ergonomics of the climatic working environment. It can also be used for other applications — for example, the assessment of working practices, the energetic cost of specific jobs or sport activities, the total cost of an activity, etc.
The estimations, tables and other data included in this International Standard concern an "average" individual:
-- a man 30 years old weighing 70 kg and 1,75 m tall (body surface area 1,8 m2);
-- a woman 30 years old weighing 60 kg and 1,70 m tall (body surface area 1,6 m2).
Users should make appropriate corrections when they are dealing with special populations including children, aged persons, people with physical disabilities, etc.
