Abstract: Using literature, video observation, and mathematical statistics to analyze the competition of Chinese and Korean male athletes in 1,500m short track speed skating in World Cup, World Championships, and the Pyeongchang Winter Olympics in 2017-2018, and compare their difference in tactical positioning and pacing strategy from both quantitative and qualitative aspects. The results show that: (1) There is a gap in performance between the two teams in the 1,500m event with the Korean men's team being better. (2) There is no significant correlation between the position ranking of each lap at the beginning of the race and the final ranking. As the number of laps increases, the correlation between the two increases. (3) Korean male athletes' position ranking in laps 1-10 is not high, while their probability of being in the leading position in the last 4 laps is higher than that of Chinese male athletes. (4) The average lap time difference between Chinese and Korean male athletes is mainly reflected in the last 4 laps and the Korean male athletes' time is much shorter. (5) The total time spent by Korean male athletes in both final and non-final match is shorter than that of Chinese male athletes. Conclusion: The Korean male team has an advantage in the 1,500 m event. The Chinese male athletes have a lower occupation rate of the leading position in the last 4 laps, and their ability to accelerate and surpass sprints is comparatively weak.
