Tactical positioning behaviours in short-track speed skating: A static and dynamic sequence analysis

Area of Science:

• Sports Science
• Biomechanics
• Performance Analysis

Background:

• Tactical positioning is crucial in short-track speed skating, prioritizing placement over time.
• Existing research often overlooks the sequential nature of race laps, treating them as independent events.

Purpose of the Study:

• To investigate tactical positioning behaviors in short-track speed skating by analyzing the sequential relationships between laps.
• To provide a comprehensive description of tactical positioning in elite short-track speed skating races.

Main Methods:

• Analysis of intermediate and final rankings from 500m, 1000m, and 1500m elite races.
• Examination of whole-race and sub-race sequences of group and winner tactical positioning behaviors.
• Utilized a large dataset of 4,135 races across eight competitive seasons.

Main Results:

• Quantified the time-evolving complexity of tactical positioning throughout races.
• Identified sequential patterns in group and winner positioning behaviors.
• Demonstrated the importance of lap sequence in understanding short-track speed skating tactics.

Conclusions:

• The sequential analysis offers a more rigorous understanding of tactical positioning in short-track speed skating.
• Findings provide insights into race strategy and can inform the design of training tasks.
• Highlights the need to consider the dynamic, sequential nature of racing for performance enhancement.
