[Status of nutrition and cell immunity in sportsmen-weightlifters]

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.
