AN ANALYSIS OF THE ENERGY EXPENDITURE IN LEVEL AND GRADE WALKING

Abstract

Each of the component energy expenditures due to changes of kinetic and potential energy during walking is estimated and compared with the observed energy expenditure of walking. Considerable interaction is shown to occur between positive and negative components. Owing to the inevitable differences which exist between individuals the prediction of at least some of these quantities is insufficiently accurate to allow the useful calculation of the total expenditure.
