[Medico-biological substantiation of producing carbohydrate-rich mixtures for the nutrition of highly-trained sportsmen].

Medico-biological requirements for the chemical composition of specialized products (mixtures) with high content of carbohydrates have been considered. The mixtures are intended for creation of energy reserves and acceleration of restoration processes in persons who were subjected to high physical and neuro-emotional stresses. The chemical composition and fatty-acid content of the high-carbohydrate nutritional mixture are presented.

[The nutrition of cyclists during training exercises and competitions].

Actual nutrition of bicyclists engaged in road cycle race was analyzed at different stages of their training (at sport camps) and during contests. The effectiveness of special carbohydrate and protein products on certain parameters of metabolism in the athletes was studied. It was found that such special products favourably affect the parameters of protein, electrolyte metabolism, health state and working capacity of the athletes.

[Method of long-term electrophoresis in gradient polyacrylamide gel with a linear change of acrylamide concentration].

The method of long-time protein electrophoresis in a gradient polyacrylamide gel with a linear change of acrylamide concentration along the gel column was used to determine the molecular mass of protein molecules and their geometric sizes. In our investigation great attention was paid to the determination of the molecular form by the peak width in densitograms of protein fractions. Besides experimental data a possible physical interpretation of the essense of empiric equation is suggested.
