[Medico-biological substantiation of producing carbohydrate-rich mixtures for the nutrition of highly-trained sportsmen]. / Mediko-biologicheskoe obosnovanie sozdaniia vysoko-uglevodnykh smesei dlia pitaniia sportsmenov vysokoi kvalifikatsii.

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.

[Energy expenditures and the functional state of the neuromuscular system in athletes regulating body weight by use of a low-calorie diet]. / Energozatraty i funkstional'noe sostoianie nervno-myshechnoi sistemy sportsmenov v usloviiakh regulirovaniia massy tela s pomoshch'iu gipokaloriinoi diety.

The latent period of myoelectric component of locomotor reaction, duration of the myoelectric reaction and amount of bioelectric impulses occurring in the muscles of athletes (wrestlers) and regulating their body weight were examined. It was shown that the regulation of the wrestlers' body weight by means of hypocaloric diet favours the working capacity and functional state of the athletes. In the course of body weight decrease, the daily energy losses were within 3500--4000 kcal.

[Energy demand of track-and-field weight throwers]. / O potrebnosti v énergii legkoatletov-metatelei.

In sportsmen-throwers the matinal exchange of rest in conditions of sport gatherings is found to be fairly high. The energy spent in a single training comprised 723--910 kcal in women and 829--975 kcal in men. In these conditions the diurnal energy spent by throwers, was 4000--4500 kcal in women and 4500--5000 kcal in men. The energy spent for the rest exchange and physical trainings comprised 70--80 per cent of the entire energy spent by the throwers in 24 hours. The caloric value of the diurnal ration was in the range of 4000--5000 kcal.

[Energy expenditures, nutritional regimen and the individual indices of the metabolic status of the students at physical education institutes]. / Izuchenie énergotrat, rezhima pitaniia i otdel'nykh pokazatelei metabolicheskogo statusa studentov institutov fizicheskoi kul'tury.

Data of a study on the factual nutrition, energy expenditures and individual indices of the nitrogen and lipids metabolism rates in students of a Physical Culture Institute of different sport specialties (heavy athletics, light athletics, wrestling, skying, cycling and rowing) are presented. Shortcomings and organization of the students' nutrition are considered and suggestions for its improvement are given.

[Characteristics of the vitamin status and of the individual indices of mineral metabolism and catecholamines in the students of sports colleges]. / Kharakteristika vitaminnogo statusa i otdel'nykh pokazatelei mineral'nogo obmena i katekholaminov u studentov sportivnykh vuzov.

Materials derived from a study on the allowances of the organism of the physical culture institutes students of different sporting specialties (wrestling, cycling, light athletics, heavy athletics) of individual vitamins (A, B1, B2, B6, PP, C) and also results of investigations of the diurnal excretion with urine in them of sodium, potassium, as well as the catecholamines metabolism rates (epinephrine, norepinephrine, DOPA and dopamine) are presented.

[Use of the specialized protein product, SP-11, in the nutrition of highly trained sportsmen in heavy athletics]. / O primenenii spetsializirovannogo belkovogo produkta SP-11 v pitanii vysokotrenirovannykh sportsmenov-tiazheloatletikov.

In research work involving participation of highly trained sportsmen-heavy athletes subject to studies was the effect of the proteinic product CII-11, developed at the Nutrition Institute of the AMS of the USSR, on the body mass gain, as well as on individual aspects, of the protein and catecholamines metabolism. Under the effect of the CII-11 intake for 7 days in an amount of 100.0 g per day all the sportsmen under examination demonstrated a gain in the body mass, growing diurnal passage of total nitrogen and urea with urine and reduced excretion of amino nitrogen. No changes in the ammonia and creatinine content in the diurnal urine occurred under the effect of the CII-11 product. The ingestion of the latter promoted activation of the mediator and hormonal members of the sympatico-adrenal system. The results of the CII-11 application in training rallies with participation of sportsmen-heavy athletes and members of the combined USSR team also bear witness to the favourable action of the product on the study aspects of the protein and biogenic amines metabolism, the body mass gains and also on the results of sporting events.

[Study of the effectiveness of using diets with a varying protein content during physical loads in an experiment on rats]. / Izuchenie éffektivnosti primeneniia diet s razlichnym soderzhaniem belka pri fizicheskikh nagruzkakh v éksperimente na krysakh.

In experiments on rats subjected for 30 days to perform a graded muscular work (swimming) the influence produced by different levels of protein in the diet (6,18 and 30% by calorific value) on the accretion of body mass, physical work capacity, diurnal passage of total nitrogen, creatinine and creatine with urine was studied. At rest and following the maximum physical efforts the sugar, lactate and pyruvic acids levels were measured in the blood of rats. Food rations with low protein content (6% of the total caloricity), when used in conditions involving physical efforts, exerted an adverse effect on the growth, development and physical work capacity of the animals. The use of a protein-rich diet (30% by caloricity) did not show any substantial advantages over the standard one (18% of protein). In rats fed on diets with 18 and 30% of protein (in terms of caloricity) the body mass gain, physical work capacity and also the nature of changes in the content of lactate, pyruvate and sugar in the blood were the same.
