Application of polarized training model in annual cycle of training ski racers

Statement of the problem. When constructing a one-year training cycle in cyclic sports, the most active use is given to the polarized training model. The article proves the relevance of the problem of using a polarized model depending on the level and class of athletes, specialization of the chosen type of distance. The purpose of the article is to identify the main features of the application of the polarized training model in the training process of ski racers. The methodology of the study consists of an analysis of scientific literature on the research problem, modeling of the training process for ski racers with the distribution of the training volume of physical activity relative to the heart rate. Research results. The polarized training model assumes the use of a large volume of low-intensity exercises (about 80% of the total load) in combination with a relatively small amount of high-intensity exercise performed, in which the intensity zone exceeds the threshold of anaerobic metabolism and is about 20% of the total volume. Conclusion. The use of a polarized training model throughout the annual cycle makes a significant contribution to the athletic performance of ski racers. Athletes representing different levels of training and specializing in various types of distance successfully use a polarized training model.
