HYPODYNAMIA OF THE SPECIALISTS OF THE MILITARY SEA FLEET UNDER THE CONDITIONS OF A LONG SEA TRIP

In order to study the effect of hypodynamia on the dynamics of the component composition of the body of military seamen of the NK, the actual state, anthropometric and biophysical indices of military seamen of a scientific research vessel under conditions of a long sea cruise was investigated. It was found that motor activity significantly decreased in the campaign compared with the same indicator at the point of permanent dislocation. The surveyed servicemen noted a mostly sedentary lifestyle. Towards the end of the campaign, part of the personnel had a thin mass of right and left legs, on average, by 0,23-0,44 and 0,22-0,4 kg, respectively, which can be considered as a mild hypotrophy of the muscles. The chemical composition and energy value of products obtained for a long sea trip did not fully meet the requirements of medical and technical requirements for marine rations (norm No. 3). A sufficiently high-calorie diet and a prolonged positive energy balance, as well as inactivity with a decrease in energy consumption in a long sea trip, leads to an increase in body weight in seamen due to an increase in the fat component of the body composition of the body. The current norm of food ration (marine ration, norm No. 3) does not need to increase its energy content, but it requires improvement in terms of a greater variety of its composition and compensation for deficiencies of vitamins A, B 1 , B 2 , PP, β -carotene and certain macroelements (potassium, magnesium and calcium) in food, for example, by introducing into the diet of modern vitamin-mineral complexes. To solve the problem of hypodynamia specialists of the Navy in conditions of a long sea campaign, it is recommended to combine food at the norm number 3 (sea ration) with regular additional physical exertion. At the same time, the actual task is to develop and introduce in the daily practice of physical exercise complexes for military personnel in a long maritime campaign. Specialists of the medical service should exercise medical control of the level of motor activity of servicemen.
