Abstract

The article includes an overview of the structural elements and materials of modern cross-country skiing, depending on the style of skiing and the level of training of the athlete. The values of the weight and width of sports equipment for athletes of various categories are given. The requirements for strength and elasticity are also described. The features of the operation of sports cross-country skis are considered, which are related to the fact that this sports equipment is used in unfavorable environmental conditions. In this regard, the diagrams of the load distribution along the length of the ski created by the athlete while riding a classic, skate or combined course are given. Diagrams of the distribution of the load on sports equipment in warm and cold weather are also presented. The main types of structures used in modern cross-country skiing are considered: sandwich, CAP and hybrid, as well as the main components of their internal structure. In addition, the ways of achieving a good slip are described. The advantages obtained by the sportsman when using lighter sports equipment were revealed. It was found that, all other things being equal, the average wedge has the greatest effect on the mass of the product. In this regard, the methods, materials and basic structural solutions necessary to facilitate this element are analyzed. To achieve this goal, it is possible to use low-density wood in the ski design, manufacture cavities in the wedge material, as well as the use of various composite materials.
