Rational nutrition of professional sportsmen of Uzbekistan

Abstract

Aim: studied 2700 sportsmen to develop scientific bases of rational nutrition of professional sportsmen in the RUz.
Material and Methods:professional sportsmen training on the bases of sport complexes of Tashkent city.Laboratory and laboratory calculated methods of investigations to estimate changes of food and energetic values of food ration on training bases were used, as well as in the study of protein and C vitamin exchange in sportsmen (24 sportsmen against the background of every day nutrition and 28 sportsmen against the background of supplementary nutrition). The assessment of nitrogen metabolism status has been performed by Waterlooy index (ratio of urine total nitrogen and urea nitrogen). Mg/h vitamin C excretion with urine has been made by titrimetric method.
Results :There obtained the data of professional sportsmen every day consumption of basic nutrients and energy by Conclusions: kinds of sport, as well as the data of biological value of their every day food that the highest average daily energy inputs for men are 7700 kcal and for women – 7500 kcal. The revealed unbalance of real nutrition and inadequacy to physiological standards shows the need of rational nutrition of professional sportsmen, its improvement by bioactive substances. There developed average daily food standards for professional sportsmen by 8 kinds of sport, calculated their food and biological value which has been increased in 20 % in comparison with real background of nutrition.It has been shown that the high effect of the use of recommended standards makes possible to normalize sportsmen indices of nitrogen metabolism and increase vitamin body supply.
