Concept Evaluation: Inter-Individual Variation as the Basis for Optimizing Nutritional Support for Special Operations Forces (SOF) Soldier.

Abstract : Part I. Substrate utilization during exercise and the factors which may effect intra-individual and interindividual variation in substrate utilization are reviewed and discussed. Customization of nutritional support for the individual Special Operations Forces (SOF) soldier during mission deployment may be feasible and recommended for optimal physical performance in the field. Part II. Physical characteristics which impact on physical performance (age, height, weight, surface area percent body fat, lean body mass) and maximal oxygen consumption (Vo(2)max) of (SOF) soldiers were compared to the same characteristics in non-SOF U.S. Army soldiers. Using these physical characteristics as criteria, SOF soldiers are a statistically distinct sub-group within the U.S. Army. Physical activity and nutrition of SOF soldiers was assessed. Results indicate that SOF soldier are highly active and that both occupational and recreational activities are very diverse. In the field, SOF soldiers consume less than 3000 kcal.da(1). Additionally, carbohydrate consumption in the field approximates 300 grams.da(1) which is less than the 400 g.day(1) recommended by the Committee or Military Nutrition.
