Energy Cost of Walking in Boys Who Differ in Adiposity but Are Matched For Body Mass.

Compared the energy cost of treadmill walking in pairs of obese and lean adolescent boys matched for total body mass. Results found no intergroup differences in the net energy cost at the two lower speeds, but obese boys expended more energy at a higher speed. Heart rate was considerably higher in obese boys. Body mass, rather than adiposity, was the main predictor of energy cost. (SM)
