Title and Subtitle: Prediction of energy cost of treadmill work

Report Date: April 1962

Authors: Iampietro PF, Goldman RF

Abstract: The relative contributions of rate progression (1.5 to 4.0 mph), grade (4 to 9%), and load (10 to 30 Kg), to the total energy cost of treadmill work were determined. The data obtained were integrated graphically with some of the available energy cost data in the literature. A useful graph is provided for estimating energy expenditure. It was tentatively concluded that for grade walking over the ranges studied, the energy cost per unit weight is essentially the same whether the weight is of the body or the load. The data are useful in that a correlation between the diverse literature reports on treadmill studies using different speeds and loads is made feasible.

Key Words: Speed, Grade, Load, Energy Cost, Treadmill.
