Assessment of еnergy expenditure and energy intake of the military institute of physical training cadets associated with their academic and professional activities

Abstract

High energy expenditure of daily activity of cadets trained at the Military Institute of Physical Training sets certain demands for cadets’ diet and correspondence of energy and nutrition value of the diet to energy expenditure. Calculated data on energy expenditures of daily routine activities of the Military Institute of Physical Training cadets, energy costs of academic training and sport-related activities are presented. Along with energy expenditure another issue of balance, namely energy intake, is considered. Calculated findings on nutrition and caloric value of a cadets’ food ration and the Military Institute of Physical Training cadets’ diet and energy consumption of cadets are presented. It is shown that cadets’ diet corresponds to average energy expenditure. A comparison of the energy value of the daily ration of cadets and their energy expenditure revealed that the food ration compensates the average energy expenditure. The exceptions are intensive training in the framework of improving athletic skills (2 trainings per day), as well as periods when individual training takes place at the same time with high energy expenditures of a daily routine (for example, snow cleaning). In these cases daily energy expenditure (up to 5000 kcal) was recorded, exceeding the energy cost of food rations and requiring increased energy supply. In addition, the vitamin status of cadets was investigated. No signs of vitamins deficiency in the food ration were revealed. However, in the spring period, a decrease in the content of ascorbic acid in urine is shown in 80% of the subjects.
