Theoretical positions of modern sport nutrition and its practical implementation

Sport results and maintaining health are considered. Conditions for the application of sportnutrition products for solving specific problems in the field of sport nutritional science are formulated. A new group of the considered products is developed, including biologically active supplements (BAS) and tonic beverages for highly skilledski orienteers, swimmers, bicyclists and biathletes. Prescription formulas and technologies for producing dry beverages and tableted forms arescientifically proved. Reduced parameters of technological processes: granulation at a temperature of no higher than 40 °С, drying of granules at a temperature no higher than 60 °С, and insignificant duration of the process provide high preservation of biologically active components andtheir functional orientation. The developed products have been tested in manufacturing conditionsat enterprises certified within the requirements ofinternational standards and the GMP rules. Theresults of clinical trials of the developed products are obtained by their use in the diet of highlyqualified athletes and study of indicators that characterize functional state of body and health indifferent periods of competitive activity. The resultsof the research showed that inclusion of BASin the basic diet of athletes provides an increase in the volume and intensity of training, promotesan increase of emotional and volitional upsurge in the period of competitive activity. Mechanismof nutritional support of an organism within thepreparatory, competitive and recovery periods isconsidered. It includes energy supply, endocrine regulation, activation of anabolic processes, improvement of vascular condition and tonus of the nervous system, increased immunity, digestion,electrolyte, amino acidprotein and fat metabolism, and supply of vitamins and minerals. Research materials allowed determining the area ofusing the sport nutrition products intended toimprove work capacity and preserve health.
