The Energy Expenditure and Food Intake of the Ship's Company of a Submarine

Abstract

The energy expenditure and food intake of the ship's company of a conventionally-powered submarine were measured under normal operational conditions. Energy expenditure measured in a representative sample of 17 men by the activity diary method and measurements of ventilation rates amounted to 2980±320 (SD) kcal/man/24 h, varying considerably with the dutie3 of the individual. Food intake was estimated by measuring the food drawn from stores and by collection and analysis of food waste and indicated an intake of approximately 3700 kcal/man/24 h whilst at sea; in addition 13 men weighed their food individually and had a mean intake of 3340± 541 (SD) keal/man/24 h.
