Locomotion: Comparative Energetic Costs

Abstract

The relative energetic cost of animal locomotion, over land, in water, and in the air, varies according to body size and the mode of locomotion adopted. Using various techniques, these costs may be measured and compared.

Keywords: walking; running; swimming; flight; energy costs
