Relationship of Diet to the Performance of the Combat Soldier
Abstract
The energy requirements in a cold environment are practically unchanged as compared to a temperate environment except for the 2% to 5% increase due to wearing heavy clothes and footgear, provided that the individual is adequately clothed. Based on observed V sub O2 increases, the daily energy requirements for men living and working in a hot environment are increased. This is related to the increased requirement of blood circulation in heat transport, increased action of the sweat glands, increased caloric loss due to sweat vaporization and to the increase in body temperature. At high temperatures with increasing relative humidities (30% to 98%) although one observes increases in V sub E heart rates and body temperatures, the v sub O2 during submaximal work appears to be unchanged. The reasons at this time are not clear. Preliminary data indicates that V sub O2, V sub E and heart rates during standardized physical activities are significantly increased at 4300 meters. This indicates that the energy requirements at this elevation may be increased.
