Pound for pound: Working out how obesity influences the energetics of walking.

摘要

Childhood and adult obesity are both serious health problems that are catalyzed by inadequate physical activity and the resulting chronic energy imbalance. For most people, walking consumes more metabolic energy than any other daily activity. Thus it is important to understand the energetic cost of walking for obese persons. Recently, physiologists have quantified the greater metabolic cost of walking by obese children and adults, and when the rates of energy consumption are expressed per kilogram of body mass, they are only modestly greater for obese vs. lean individuals.
