Methodological principles of the physical training system for cross-country skiers

The article presents a conceptual proposal for organizing the structure of the patterns of the physical training system of ski racers. The dependence of the structure and content of physical training on the variability of competitive activity, formed under the influence of the dynamism of social processes and conditions, is substantiated. The cause-and-effect relationships of the training process with the factors on which this process depends are revealed. The study was carried out using theoretical methods that made it possible to clarify and systematize scientific knowledge, as well as explain pedagogical phenomena from the point of view of biological facts and establish relationships between pedagogical concepts. Having organized numerous information about the laws and patterns in pedagogy and didactics, we presented our conceptual proposal for the structure of the patterns of the physical training system of ski racers. Since the training process relates to sports and pedagogical activities, a number of patterns identified by many authors of pedagogical theories can be adapted in the process of physical training. Based on the analysis and generalization of numerous literary sources, the article substantiates and formulates the methodological principles of the system of physical training of cross-country skiers. The dependence of the presented patterns on cause-andeffect relationships and factors on which the physical fitness of athletes depends is indicated. The patterns were differentiated into external and internal. Particular attention is paid to a group of patterns expressing internal connections between the process of physical development and the result of physical training in the system of long-term training of an athlete.
