The objective of the current study is to define a range of energy requirements of service women, defining the variation as it relates to jobs, military settings, and activity patterns. This is crucial information needed not only for determination of nutritional requirements for energy balance, but specific nutrient density standards for servicewomen. Total daily energy expenditure is measured using the doubly labeled water DLW method. Activity patterns from actigraphs will be analyzed for hours of sleep, description of jobwork patterns by examining bursts of concerted activity versus steady activity. Men will also be studied in these settings. Energy requirements for men have been better established and will serve to anchor the results obtained in women to previously established norms in men. Several field studies will be conducted over the course of the grant. The first field study was conducted at Fort BraggCamp Mckall during a Combat Support Hospital training exercise. Energy expenditures were moderate, and higher in men than women. However, when adjusting for differences in body size, energy expenditures were similar.
