    8. 8. Activity Monitoractivity level evaluation josue@grpss.ssr.upm.es temporal evaluation windows: short-term (t = 1 hour) s alarm generation long-term (t = 24 hours) l 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).
