Fig. 3From: Comparison of dietary intakes of Canadian Armed Forces personnel consuming field rations in acute hot, cold, and temperate conditions with standardized infantry activitiesComparison of energy intake with energy expenditure during the 8 h experimental treatment and during the 6 h posttreatment period (as part of a randomized experimental trial). Study participants were Regular Force or Class A Reservists (n = 18). The data presented are for 8 h and 16 h (a total of 24 h) of energy intake and expenditures (39) of CAF personnel participating in the four experimental treatments (sedentary (21 °C), cold (− 10 °C), hot (30 °C) and temperate (21 °C); humidity (~ 30% under sedentary, hot and temperate treatments and 50% in the cold treatment). Energy intake data were collected using the measured food intake/food waste method, where all consumed and/or non/partially consumed food and beverage were weighed and recorded for each participant. Strenuous physical activity consisted of infantry activities during the 8 h experimental treatments (for detailed analyses on energy expenditure, see Mandic et al. [40]).Back to article page
