An assessment of the increase in the efficiency of gas exchange was carried out on the example of students of an engineering university with the daily use of an additive containing food components with known bio-correcting properties: flour of wheat germ cake Ц 45%, sprouted chickpea seeds Ц 15%, dried leaves of japanese kelp Ц 5%, a component of animal origin in the form of whey protein concentrate Ц 35%. The change in the energy efficiency of the nutritional status was assessed based on the analysis of the concentration of carbon dioxide (CO2) and oxygen (O2) in the exhaled gas mixture and the level of hemoglobin oxygenation (SpO2), the values ??of which were recorded before and after daily consumption of the test products for 30 days. The study group of patients consisted of volunteers among first-year students of the Voronezh State University of Engineering Technologies - boys and girls aged 17-18 years. In the course of experimental studies, the subjects showed an increase in the SpO2 level by 0,83% and CO2 by 4,06%, as well as a decrease in the O2 concentration by 2,62% in the exhaled gas mixture. The data obtained indicate an increase in the level of oxygenated hemoglobin in the subjects' blood, accompanied by a shift in the active blood reaction (pH) towards an alkaline medium, which occurs between the alveolar air and the blood of the pulmonary veins and capillaries due to the diffusion of CO2 through the alveolar membrane. An increase in the concentration of CO2 in exhaled air is accompanied by an increase in the efficiency of O2 transport, and also prevents the formation of erythrocyte complexes as a result of changes in the physicochemical properties of the membrane. The data obtained make it possible to state the possibility of an active alimentary effect on the efficiency of gas exchange, and prove the antihypoxant properties of the enrichment additive. The reliability of the experimental data was assessed using the Mann-Whitney test, which confirmed the presence of a positive effect of the components of the enrichment supplement on the human body. The results of the work convincingly prove the role of alimentary factors in increasing the efficiency of the most important functions of the body of adolescents of the older age group, regardless of gender, which naturally leads to an increase in the body's resistance to changes in external and internal influences. The data obtained in the course of research indicate the possibility of classifying the components of the supplement as alimentary biocorrectors that ensure the effectiveness of the process of energy metabolism of the body in adolescents.
