[Change in lipid metabolism in sports wrestlers under conditions of physical load and body dehydration].

Control of forty six sportsmen-wrestlers determined that the loss in weight accounting for 3.5% leads to a certain reduction of nonesterified fatty acids (NEFA) in venous blood and to a significant increase in the content of esterified fatty acids (EFA), beta-lipoproteids, phospholipids and cholesterol. Analogous as to the trend (excluding NEFA) but a little less pronounced changes these values occur after physical load on sportsmen who did not undergo dehydration. Under conditions of dehydration a 40-minute work on veloergograph caused additional changes in the values under study. An hour after finishing the physical work the total level of lipids as well as of their fractions such as beta-lipoproteids, EFA and cholesterol remains considerably higher than that in the control. Thus, the loss in weight itself as to the character of the changes arising in the lipid metabolism is to some extent similar to physical load suffered by a sportsman organism and therefore may exert unfavourable effect on the working capacity.
