Pulsimetry proved to be the most acceptable method for estimating energy requirements of miners working under extreme conditions with constantly changing ergometric parameters. It has been established that the mean daily energy requirements of miners working in deep coal mines under conditions of high temperature comprise 3500 kcal. Energy requirements for the main types of the physical activity of workers in deep mines have been calculated, basing on basal metabolism, metabolic constants for varying activities have been determined.

Providing with ascorbic acid, thiamine, riboflavin, vitamin B6 and niacin was studied in miners at deep levels before and after intake of correcting doses of vitamins. Enrichment of the food ration with vitamins produced a positive effect on the working capacity of the miners under study. The levels of vitamin consumption (vitamin-energy coefficients) have been estimated correcting the vitamin balance in miners working at deep levels.

The authors have studied the ways of correcting the vitamin status and influence of vitaminization on working capacity in workwomen in light industry. Prophylactic polyvitaminization (1 dragee of "Undevitum"/day, during 2 months) proved to produce positive effect on the vitamin status parameters (vitamin content in the blood and urine, clinical microsymptoms of vitamin deficiency), and on the dynamics of the physiological parameters of working capacity of workwomen at modern conveyer shoe making industry. It is recommended that persons suffering from chronic diseases influencing vitamin metabolism, first of all those over 45 years, should receive increased doses of prophylactic polyvitamins, thiamine and ascorbic acid, in particular.

It has been shown that there is no necessity in dividing the population capable of working into groups according to their age, as gradual ontogenetic decrease in the cellular metabolism takes place in the presence of parallel physiological growth of body mass. The authors have divided the population capable of working into groups of intensive work depending on their daily energy requirement, with an interval of 400 kcal. It is recommended that the data presented be used for the development of an exactly defined variant of physiological nutrition standards.

The energy expenditures in the nonproductive period in the women-workers of the boot and shoe industry (group I) and the sewing industry (group II) were almost similar: in group I it was on an average 1372 +/- 35.4 kcal, in group II--1384 +/- 27.6 kcal. In the productive period the energy expenditures in the workers of group I fluctuated from 1.56 to 2.09 kcal/min, in those of group II--from 1.78 to 2.27 kcal/min. Summary energy expenditures in the productive period comprised 877 +/- 91.1 kcal (in group I), and 949 +/- 51.1 kcal (in group II). Daily energy expenditures were 2249 +/- 77.1 kcal and 2333 +/- 63.9 kcal, respectively. The energy value of the rations of their actual nutrition insignificantly exceeded their energy expenditures (on an average by 120-150 kcal) due to excessive fat consumption, animal fat, in particular. Their rations were characterized by protein, and, to a lesser extent, carbohydrate deficiency, by imbalanced mineral composition and vitamin A, B1, B2, PP and C deficiency. Microsymptoms of vitamin deficiency (mainly those of vitamin C deficiency) were detected in 64% of the examined subjects, excessive weight was found in 23-26% and obesity in 11-16% of the women. The women working at the modern boot and shoe and sewing industry should be referred to the first category of the work intensity, with respect to the energy requirements and the energy value of the nutrient components of their food rations.

The diet specificity was studied in 335 male workers engaged in blast-furnace and open hearth plants, rail-structural, oxygen converter and sheet-rolling mills of the steel plant. The energy value of the diets under study amounted to 3746-4091 kcal a day, with the mean value being equal to 3947 kcal. The content of proteins including those of animal origin and the content of mineral substances corresponded with health recommendations. The content of carbohydrates and vitamins was slightly less as compared to that according to the recommended physiological requirements. The diet was abundant in fats, particularly in those of animal origin. Overweight was recorded in 18.9% and obesity in 5.8% of the workers.

Energy losses were studied in 60 male students aged from 18 to 25 years, who worked at the construction sites during the summer. The daily energy losses averaged 4084 kcal for brick-layers, 4314 kcal for concrete workers, 4356 kcal for carpenters, and 4517 kcal for auxiliary workers. Recommendations were made for average daily requirements of students from construction teams for principal food products and energy as well as for an average daily diet. The diets were developed with due regard for energy and food supply of students and for food balancing. These diets also provide for four-time meal regimen, specificity of nutrition organization at students' teams as well as climatic and geographical features of the Ukrainian SSR.

Groups of young sexually mature and old albino rats were kept for three months on 4 isocaloric rations, viz. balanced, with reduced proportion of essential fatty acids or group 'B' vitamins and with simultaneous curtailment of fatty acids and vitamins. With vitamin deficiency there was a certain derangement in the structure and function of the small intestine, especially in older animals. A shortage of essential fatty acids impaired the condition of the small intestine only in old animals. In cases of concurrent deficiency of vitamins and essential fatty acids maximal changes in both young and old animals were in evidence.
