PROSPECTS OF USING THE RESULTS OF STAGE COMPLEX CONTROL FOR PREDICTING THE PERFORMANCE OF COMPETITIVE ACTIVITIES IN DISTANCE RACES OF HIGHLY QUALIFIED FEMALE CROSS-COUNTRY SKIERS

The research purpose is to develop a regression model of rating points in distance races of the winter season of female cross-country skiers based on the results of stage complex control (on the example of the results of the Cup of Russia 2023-2024). 

Research methods: analysis of scientific studies; pedagogical testing: field test on roller skis, step-increasing load on a ski ergometer; medical and biological testing: registration of the latent time of evoked contraction (LTEC), biochemical blood analysis; methods of mathematical statistics: standard Microsoft Office Excel package; regression analysis: least squares method, Python 3.10 programming language in the Google Colab environment.

Research results and their discussion. 132 indicators of the results of the specialized program of stage complex control (SCC) of female cross-country skiers were analyzed (field test – 70; laboratory tests – 62). It is shown that the results of the SCC in the preparatory period are informative for determining the prospective results of female cross-country skiers in the winter sports season. A regression model has been developed to calculate the rating points of the Russian Skiing Federation in distance races for female athletes in the winter season. The model contains variables and constants reflecting the results of field and laboratory testing in the preparatory period.

Conclusion. The results of the study determined that five indicators are informative for distance races. To calculate the prospects for rating points in distance races, it is necessary to analyze the dynamics of the increase in the following indicators at the stages of the preparatory period: the speed of the first and fourth test circles, the time to overcome the downhill part of the terrain of the third test circle of the field test on roller skis, the minimum level of the LTEC of the motor unit of the right leg and the level of tension in the response of glycolytic motor units of the right hand. The results obtained can be used to manage the process of training highly qualified female skiers in the preparatory period.
