Abstract

The results of studies of alimentary correction of the efficiency of gas exchange in the lungs by the example of students and teachers of an engineering university with daily use of foods with known bio-correcting properties: 3.5 g of wheat germ oil (WGO), 50 g of wheat germ meal cake (WGMC), are presented 6.5 g of concentrated tissue fish oil (CTFO) and their combinations with the biomass of the consortium of lacto- and bifidobacteria (10 g). The efficiency of gas exchange processes was evaluated based on the analysis of the respiratory coefficient, the concentration of carbon dioxide (CO₂) and oxygen (O2) in the exhaled gas mixture was determined using a TESTO-310 gas analyzer, an MDG-1201 capnograph, the values of which were recorded before and after daily use of the studied products during 30 days. The experimental group consisted of volunteers – teachers and university students aged 16 to 65 years, divided into 3 age groups: 16-24, 25-44 and 45-65 years old. It was established that the most effective antihypoxic drug is WGMC, in all age groups, the increase in average RR values amounted to 0.041 units, and 4.8% relative to the initial values. When using WGO, the change in RC was 0.032, an increase compared to baseline – 3.7%. In the 1st, 2nd and 3rd age groups, the average change in RC was: 0,031, 0,036 and 0,043 units, relative to the initial indicators, the increase was 3.5, 4.2 and 5.0%, respectively. It is proved that the combination of the studied biocorrector with the active forms of probiotic microorganisms provides a more active antihypoxic effect for all the studied products in all age groups. The effectiveness of the WGO was increased, the increase in RC was 0.049 units, for CTFO – 0.024 units. The growth of RC relative to the initial values was 5.7 and 2.9%, respectively. The synergism of the action of biocorrectors in combination with probiotics, by age groups amounted to – 0.035, 0.033 and 0.038 units, which is 4.1, 3.8 and 4.5% relative to the initial indicators.
