Abstract
The purpose of this study was to measure the energy cost of walking one mile on the flat to quantify the number of calories in an “Energy Mile”, and to test Petzoldt’s Energy Mile Theory. Petzoldt defined one energy mile as the energy required to walk a one mile on the flat. He recommended adding two energy miles for every 1000 foot elevation gain. To determine the validity of Petzoldt’s theory, this study measured the energy cost and perceived exertion for walking on the flat, with and without a backpack, and up an elevation gain of 1000 feet. From the data, a 1.6 mile equivalent for 1000 feet was revealed. Differences between females and males ranged from 1.32 to 2.02. Further research using heavier expedition packs at higher altitudes could reveal changes in energy cost.
