The efficiency of the correction of diet using dietary supplements and special foods for athletes has been evaluated in 21 highly qualified swimmers, aged 17 to 26 years, during training cycle in midlands (altitude 1792 m above sea level). A personalized approach, consisting of the timely correction of individual programs of biomedical support, especially nutritional correction is directly linked to the performance of the functional state of an athlete in the most important period of training in midlands. At the end of training gathering the increase in AcT, ALT blood plasma activity by 18-42% and the reduction in the activity of creatine kinase by 26% in the normal ranges (p < 0.05), as well as increased cortisol level by 35% was noted, indicating an adequate voltage of the body systems in response to the load presented in conjunction with the use of pharmacological correction. Hemoglobin concentration in blood increased by 5.6% (p < 0.05). Assessment of body composition showed that by the end of the training cycle in midlands there was an increase of active cell mass by 3.5% (p < 0.05). Significant (p < 0.05) increase in oxygen consumption (by 7%) along with the improvement of swimming in the 200 m in the zone of anaerobic threshold (ANSP) (by 5%) at the end of the training cycle demonstrate the effectiveness of the training process conditions and effective use of nutritional support.
The analysis of average daily nutrient intake, indexes of lipids metabolism parameters of cell immunity on 30 weightlifters and 14 individuals, who does not be engaged in sport, are carried out. Results of the present research show the imbalance in athletes diet with unfavourable ratio of proteins, fats, carbohydrates as 1:1,7:3--in women and 1:1,4:2,9--in men. Lipid storage disease include the rise of low-density lipoproteins level (in women-- 3,2 +/- 0,2; in men--3,4 +/- 0,2 (p < 0,05); in control group--2,2 +/- 0,3 mmol/l) and the fall--of high-density lipoproteins (in women--1,3 +/- 0,1; in men--0,9 +/- 0,1; p < 0,05); in control group--1,7 +/- 0,2 mmol/l). Result of disbalance in sportsmen immune system was statistically authentic decrease in an immunoregulatory index of CD4/CD8 (in women--0,89 +/- 0,08, in men--0,77 +/- 0,11; p < 0,05) at the expense of increase of the relative maintenance of cytotoxic CD3+CD8+ T-killers (in women--39,42 +/- 4,0; in men--41,28 +/- 3,28%; p < 0,05) and reduction of the T-helpers CD3+CD4+ content in peripheral blood (32,48 +/- 1,06 and 31,33 +/- 2,95%; p < 0,05) at 17% of women and 42% of male athletes owing to intense physical activities. This suggests that athletes engaging in longer periods of intensified training can exhibit an inefficiency of cell immunity. The cause of immune response decreasing can be metabolic disorders. The imbalance in athletes' diet leads to dislipoproteinemia, which play a pathogenetic role in cell immunosuppression.
Contemporary domestic and international experience of forming a diet for young athletes involved in various kinds of sport was considered at the article.
The goal of the survey is the analysis of economic efficiency at 20% one-time as well as 20% and 30% even reduction of anemia prevalence. Data of Agency on statistics, Ministry of Health of Republic of Kazakhstan, and research data of Kazakh Academy of Nutrition were used for computation. The prevalence of anemia amongst men aged 15-59 years was 28,1% and amongst women aged 15-59 years--45.3%. The economic efficiency at the 20% one-time anemia prevalence reduction for 1 year accounts for 146.1 mln USD, at the 20% even reduction of anemia prevalence for 4 years--367.7 mln USD for this period or 91.9 mln USD per one year; and at 30% even reduction of anemia prevalence for 4 years--547 mln USD for this period or 136.7 mln USD per 1 year.
The classification and composition of specialized foods for sportsmen are presented. The perspective of application of contemporary biologically active substance to the development of new foods is discussed for nutrition sportsmen.
Zinc oxide nanoparticles labeled with 65Zn were administered once intragastrically to male Wistar rats. The distribution of radionuclide-marker (65Zn) was measured by gamma-spectrometer in tissue samples of animals the organs through 4 hours, 1, 3 and 5 days after administration, and in the wastes of animals through 1 since 5 days. The data obtained demonstrate for the first time the bioavailability of zinc trace element in the form of its oxide nanoparticles.
A positive effect on metabolic processes in hypertension and coronary heart disease in remission of a low-calorie dietary supplement containing a small amount of carbohydrates and fats was determined. The food substance, which contains a negligible amount of carbohydrates and fats, compensated a daily need in proteins and made a regulative impact on gastrointestinal tract function. The effectiveness of the food substance became apparent: in lipid metabolism normalization, glucose level in blood decreased to standard values, functions of liver and cardio-vascular system became normal.
The results of studies on the detection of gluten in the 7 products, members of the group of gluten-free, used for patients with celiac disease. Used the method of polymerase chain reaction detection in real time (by method of polymerase chain reaction) using a test system SureFood Allergen Gluten. With this method, fully meets the requirements of the Codex Alimentarius Commission, confirmed the compliance of the investigated food gluten-free category, used for patients with celiac disease.
