The paper is focused on the issue of modeling competitive activity of elite athletes, specializing in short-track, in the 500m, 1000m and 1500m events on the basis of identifying various tactical options for running distance. Based on the analysis of speed dynamics, it was found that the world’s strongest athletes use various options to skate the distance in short track, but in most cases, in the 500m distance they skate at a minimum distance speed on the first lap, and reach the maximum speed on the second lap; in the 1000m distance they skate slowly on the second lap and achieve the maximum speed on the fourth lap; and at the 1500m distance the slowest lap is the second whereas the fastest is the fifth. The author has proposed prognostic models of competitive activity in short track in the 500m, 1000m and 1500m distances, which take into account different tactical options for skating. Mastering the selected option is possible when targeting developed prognostic models of the competitive activity with clearly identified quantitative criteria, corresponding to a particular level of special preparedness of athlete.
