Determination of Total Daily Energy Requirements and Activity Patterns of Service Women
Abstract
The objective of this study was to determine energy expenditure in service women in various military settings and to determine if differences in total daily energy expenditure (TDEE) are explained primarily by differences in body size and fat-free mass after differences in activity patterns are accounted for. As originally planned, 5 field studies were conducted. A total of 80 Females (FEM = 45.9 plus or minus 7.1 kg) were studied with an average of total daily energy expenditure of 3340 plus or minus 1270 kcal/d. A total of 53 males (66.3 plus or minus 9.0 kg FFM) were studied, with an average TDEE of 4870 plus or minus 1480 kcal/d. Since men were larger than women in all studies, men had a higher TDEE than women overall, and in each individual study. However, when adjusting for differences in body size, the energy expenditure of men and women were similar in all studies. Energy expenditures during the short term Crucible studies were very high, possibly some of the highest energy expenditures we observed, and higher than the other 3 studies. The Crucible studies provided an excellent paradigm to examine energy expenditures between men and women because all recruits underwent essentially the same activities and were on the same sleep/wake regimen.
