Champion Position Analysis in Short Track Speed Skating Competitions From 2007 to 2019

Purpose: Short track speed skating is a racing sport with racing tactics are equally crucial to speed and technical skating skills. Therefore, to investigate the relationship between starting and finishing positions for elite skaters and subsequently, explore pacing patterns for champions are necessary.Methods: To investigate a pattern of effective tactical positioning strategy, Kendall’s tau-b correlations between starting and finishing position were calculated, with 500 m races having the most positive correlation (0.347, P < 0.05).Results: Furthermore, starting position distributions of winners in each round, as well as the fluctuations in champion starting positions across rounds were analyzed. Our findings showed that skaters on the first track were inclined to win the rounds in 500, 1,000, and 1,500 m (28, 28, and 22%, respectively), and the differences between starting and finishing positions for champions were minimized in semi-finals. Meanwhile, the pacing patterns were gaining more fluctuations by the increase of race distances for champions, as the average standard deviation of lap rankings equaled 0.90, 1.15, and 2.21 for 500, 1,000, and 1,500 m races, respectively.Conclusion: In conclusion, elite skaters should adopt flexible tactics at the lowest cost of energy consumption. The overall variability of lap ranking in long-distance races were distinctly higher than it in short distance.

Speed Skating Technical Training Based on Sports Biomechanics

Objectives: With the vigorous development of China’s sports industry, sports industry has displayed its own sports spirit on the world stage, especially in the speed skating sports. Methods: The combination of sports biomechanics and speed skating training not only helps to improve our speed skating level, but also helps to inherit the tradition of combining sports theory and practice in our country. Results: The speed skating technique based on sports biomechanics can use the knowledge of biomechanics to combine speed skating with mechanical system better. Conclusion: The high-speed camera can be used to collect the players’ training, and the frame rate adjustment function of the computer can be used for frame by frame analysis to ensure the posture correctness of the speed skaters.
