Study of the double poling kinematics of elite cross-country skiers

Abstract

Highly skilled cross-country skiers often prefer the double poling technique due to its speed and versatility. This work is aimed at developing a biomechanical model of a skier using the double poling technique. To do this, using video recordings of the competition, experimental data of eight elite-level athletes (four males and four females) were prepared and analyzed, who used the indicated technique while passing the distance. The analysis made it possible to determine the dependence of the angles in some joints on time, as well as to assess the repeatability of the double poling movement from cycle to cycle. As a result, the main control parameters were identified by which the skier regulates the pace of his movement along the track and the geometric characteristics important for modeling. Statistically significant differences in technique for male and female are shown (P < 0,01), which is extremely important in the development of personalized models of movement. The conclusions drawn will contribute to the correctness of the construction of a mathematical model of double poling biomechanics.
