[The effect of a rapid decrease in body weight and enriching rations with microelements on various functions of the athlete's body]. / Vliianie bystrogo snizheniia massy tela i obogashcheniia ratsionov pitaniia mikroélementami na nekotorye funktsii organizma sportsmenov.

In athletes of high skills, a 5-percent decline of the body weight over 5 days by means of restricting water, fats and carbohydrates consumption was followed by reduced activity of ceruloplasmin and lysozyme of blood serum. After sauna attendance with a purpose of lessening the body weight, there was, along with a certain rise of the immunologic responsiveness of the body, a decrease in peroxidase activity, in the content of iron and copper in blood cells in the presence of appreciable losses of trace elements with sweat. Enrichment of the athletes' diets with trace elements combined with vitamins and bendasole hydrochloride in the course of sauna-induced body weight lessening not only prevented the negative alterations but also exerted a beneficial action on the function of certain body systems.

[Changes in the content of iron, copper and manganese in animals during disadaptation caused by heavy loads]. / Izmenenie soderzhaniia zheleza, medi i margantsa v organizme zhivotnykh pri dizadaptatsii, vyzvannoi vozdeistviem bol'shikh nagruzok.

The exchange of microelements in the animal organisms under the influence of overtraining with static loads has been studied. In chronic experiments on 11 male dogs of impure-breed by the method of emission spectral analysis it has been established that the heavy physical loads cause the decrease of iron content in blood and a simultaneous reduction of the iron content and, partially, copper and manganese content in the internal organs of animals. The addition of microelements to the usual food allowance promotes the faster restoring of the violated microelement balance and animals' capacity for work.

[Effect of the intake of different doses of trace elements and their combination with other biologically active substances on iron, copper and manganese metabolism in highly qualified athletes]. / Vliianie priema razlichnykh doz mikroélementov i ikh sochetanii s drugimi biologicheski aktivnymi veshchestvami na obmen zheleza, medi i margantsa u sportsmenov vysokoi kvalifikatsii.

Investigations conducted on athletes have shown that combinations of trace elements (Fe, Cu and Mn) in biotic doses with vitamins, glutamic acid or dibasol produce a favourable effect on trace element metabolism, and on the body functions. Enrichment of food rations with vitamins only, using no trace elements, drastically increased the secretion of Fe, Cu and Mn from the body. High doses of Fe-containing drugs disturbed Mn balance.

[Zinc and silicon metabolism in highly trained athletes during heavy exercise]. / Obmen tsinka i kremniia u sportsmenov vysokoi kvalifikatsii pri bol'shikh sportivnykh nagruzkakh.

Trained male athletes were under study. It was found that under the effect of physical stress during the contest in ski race (30 and 50 km) the increase of the zink and silicon levels in the blood plasma correlated with their decrease in the blood cells. A positive zink and silicon equilibrium was observed in the athletes on the day of rest before the contest. Excretion of zinc and especially of silicon through the kidneys and intestine drastically grew on the day of the contest. On the day of rest following the high muscular stress the loss of trace elements appreciably lowered, however, it was higher than that before the contest. The authors recommend the following doses of the trace elements for highly trained athletes: zink--20-25 mg/day, silicon--30-35 mg/day.

[Microelement metabolism in humans and animals during hypoxic states of different etiologies]. / Obmen mikroélementov v organizme cheloveka i zhivotnykh pri gipoksicheskikh sostoianiiakh razlichnykh étiologii.

This paper reviews reported data and results obtained by the present authors which describe metabolic pathways of trace elements in humans and animals during hypoxia of different origin, discusses possible causes and symptoms of their deficiency and presents methods of restoring the balance of trace elements.

[Effect of alcohol on iron, aluminum and zinc balance]. / Izmenenie balansa zheleza, aliuminiia i tsinka pod vliianiem alkogolia.

An increased loss of iron, aluminium and zinc through the intestine and kidneys, creating the preconditions for the development of deficiency of these metals in the body, was recorded in males and females, engaged in sports, after single intake of moderate doses of alcohol. The next day after the alcohol intake males showed elevated retention of iron, aluminium and zinc, while females--that of iron only. In the latter the loss of aluminium and zinc still prevailed over intake of these metals with food.

[Dynamics of the amino acid composition of the blood during adaptation to muscular loads]. / Dinamika aminokislotnogo sostava krovi pri adaptatsii k myshechnym nagruzkam.

A single fatiguing muscular load results in increase of the blood free amino acids concentration in animals. Regular training with moderate physical loads leads to amino acid content increase during first weeks of training and then to its normalizing in the process of adaptation to loads. Excessive training with heavy muscular loads is accompanied by the decrease of essential amino acids concentration in the blood.

[Comparative effectiveness of microelements added to the diet of athletes during training in different seasons]. / Sravnitel'naia effektivnost' mikroelementnykh dobavok k pitaniiu sportsmenov pri trenirovke v raznoe vremia goda.

Twenty-five athletes were entered into the study. Emission spectral analysis employed in the study demonstrated that during the spring-autumn months, there was a considerable decrease in the blood content of iron, copper and manganese as compared to that seen during autumn and winter. That decrease was associated with a negative trace elements balance in the body and low content thereof in the athletes' diet. Enrichment of the diets with iron, copper and manganese combined with vitamin C during winter was followed by a less marked effect on trace elements metabolism, the growing red fiber of the blood, working capacity and immune resistance versus the use of the same trace elements in the athletes' diet during summer. The greatest effect was attained upon the intake of trace elements in combination with ascorbic acid and dibazol.
