Comprehensive study of the kinematics of double poling cross-country skiing: experiment, processing and modeling

In high performance sports, high results are usually the product of a whole set of achievements. Innovations in materials, training methods and techniques allow you to win and set records. One of the ways to improve results in cyclical sports, such as cross-country skiing, is to use information about the biomechanics of athletes movements. Analysis of the athlete's movement parameters allows us to characterize the effectiveness of these movements, as well as to develop tactics for conducting the race. In this paper, we present a method for obtaining data, develop an algorithm for digitizing them, and propose a mathematical model that describes a set of data on the movements of cross-country skiers. During the analysis of mathematical modeling data, a significant influence of both the class of skiers and their gender on the parameters of the mathematical model was revealed. The results of this study can be useful for a deeper understanding of the fundamental biomechanics of cross-country skier’s movements, as well as for building more optimal training techniques.
