TABLE 15-2 Metabolic Rates (65-kg human) Activity Sleeping Sitting upright Light activity Metabolic Rate (approximate) kcal/h watts 60 70 100 15 200 230 (eating, dressing, household chores) Moderate work 400 460 (tennis, walking) Running (15km/h) 1000 1150 Bicycling (race) 1100 1270

Average metabolic rate = total energy spent/ total time
