Determination of Total Daily Energy Requirements and Activity Patterns of Service Women
Abstract
The objective of the current study is to define a range of energy requirements of servicewomen, 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 job/work patterns by examining bursts of concerted activity versus steady activity. Energy requirements for men have been better established and will serve to anchor the results obtained in women to previously established norms in men. The first field study was conducted at Fort Bragg/Camp 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. Very high energy expenditures were observed during the Crucible studies in Marine Recruits. Further data analyses for this study are being carried out. Planning for the next studies are underway. The Shipboard study is planned to occur in November or December of 1999. The Marine Basic Training Study planning is underway and should occur early in 2000.
