[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.

[Energy expenditures and the functional state of the neuromuscular system in athletes regulating body weight by use of a low-calorie diet].

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].

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.
