Optimizing the Team for Required Power During Track-Cycling Team Pursuit

Area of Science:

• Sports Science
• Aerodynamics
• Cycling Performance

Background:

• The men's team pursuit in track cycling requires covering 4000m as quickly as possible.
• Optimizing aerodynamic drag is crucial for enhancing speed and performance.

Purpose of the Study:

• To quantify the drafting effect in the second, third, and fourth positions during team pursuit.
• To analyze the influence of individual frontal areas on drafting efficiency.
• To minimize the power output required for cyclists in drafting positions.

Main Methods:

• Eight elite track cyclists completed 39 trials of 3km at a constant velocity (15.75 m/s).
• Individual frontal projected areas were measured.
• Drag coefficients for all four positions were determined in field conditions.
• Generalized estimating equations were used to model relationships between frontal areas and drag fractions.

Main Results:

• The frontal area of the leading cyclist and the drafting cyclist significantly influenced drag fraction across all drafting positions (P < .05).
• Predicted individual power requirements varied by up to 35W based on team composition.
• Team efficiency varied by as much as 1.2% depending on the specific rider sequence.

Conclusions:

• Team composition and rider sequencing substantially affect individual power demands and overall team efficiency in the team pursuit.
• Accurate estimation of required power for specific team configurations provides valuable insights into optimizing performance.
