Bottom Line: Overall energy expenditure adjusted for body composition was 17,606 ± 2326 kJ·day(-1).Energy expenditure was 19,110 ± 1468 kJ·day(-1) during CDQC and 16,334 ± 2180 kJ·day(-1) during PMT, with physical activity levels of 2.6 ± 0.2 and 2.2 ± 0.3 during CDQC and PMT, respectively.Compared to the Military Dietary Reference Intakes for energy (13,598 kJ·day(-1)), these data are in agreement with previous reports that energy requirement for SOF Soldiers exceed that of the average soldier.

ABSTRACT
Special Operations Forces (SOF) regularly engage in physically demanding combat operations and field training exercises, resulting in high daily energy expenditure, and thus increased energy requirements. However, the majority of studies assessing energy requirements of SOF have been conducted on soldiers going through intense SOF initiation training. The objective of the current investigation was to determine the energy expenditure of SOF conducting military training operations. Thirty-one soldiers taking part in Pre-Mission Training (PMT n = 15) and Combat Diver Qualification Courses (CDQC n = 16) volunteered to participate in this observational study. Energy expenditure was determined using doubly labeled water. Body weight (83 ± 7 kg) remained stable during both training periods. Overall energy expenditure adjusted for body composition was 17,606 ± 2326 kJ·day(-1). Energy expenditure was 19,110 ± 1468 kJ·day(-1) during CDQC and 16,334 ± 2180 kJ·day(-1) during PMT, with physical activity levels of 2.6 ± 0.2 and 2.2 ± 0.3 during CDQC and PMT, respectively. Compared to the Military Dietary Reference Intakes for energy (13,598 kJ·day(-1)), these data are in agreement with previous reports that energy requirement for SOF Soldiers exceed that of the average soldier.

Mentions: Thirty-one male soldiers participating in CDQC and PMT volunteered to participate in this 7-day observational study. Two volunteers were medically withdrawn from CDQC during data collection; as such, data were collected and analyzed on 29 soldiers (CDQC; n = 14, PMT; n = 15). The experimental design is depicted in Figure 1. Energy expenditure and body weight were assessed daily each observation period. Participation in the study was voluntary, with written consent being obtained from each soldier before the initiation of data collection. This study was conducted after review and approval by the US Army Research Institute of Environmental Medicine Human Use Review Committee. Investigators adhered to US Army Regulation 70-25 and US Army Medical Research and Material Command regulation 70-25 on the participation of volunteers in research.
