Energy cost is specifically measured in PARs (Physical
Activity Ratio). The number of PARs associated to any
activity only depends on the activity itself and not in the
person performing the activity: PARs are multiple of BMR
(Basal Metabolic Rate) per minute (BMR is the minimal
rate of energy expenditure compatible with life).
