Analysis of modern scientific literature shows that the functional and physico-chemical state of plasma lipids is an important aspect in the assessment of athlete's adaptive abilities. The study analyzes a correlation between the lipid metabolism and competitive success rates in the elite cross-country skiing sport. A statistical data processing toolkit was applied to analyze the FIS-point data versus the lipid metabolism rates to produce an integrated rate indicative of the individual competitive success. We classified the sample into four clusters by the IR versus the competitive success rates. It was found that the first-cluster competitive success rate can be achieved and maintained conditional on the training process giving a high priority to the hypoxic trainings to modify the muscular fibers; with the hypoxic effects controlled by the blood triglyceride rates that must be kept at around 1.5411 mmol/ l. Objective of the study was to find correlations between the lipid metabolism (with triglyceride TG, low-density lipoproteins LDLP, very-low-density lipoproteins VLDLP, high-density lipoproteins HDLP, and the total cholesterol TC rates) and competitive success rates in the elite cross-country skiing sport. Sampled for the study purposes were the 18-25 year-old elite male cross-country skiers (n=17) with a wide range of FIS-points, and with the lipid metabolism in the sample tested by a qualitative biochemical analysis of the blood serum.

Keywords: cross-country skiers, triglyceride, lipoproteins, cholesterol, hypoxic training, anaerobic glycolysis.
