Determining optimal cadence for an individual road cyclist from field data

Area of Science:

• Sports Science
• Biomechanics
• Exercise Physiology

Background:

• Optimal cadence, maximizing cyclist power output, is typically found via laboratory testing.
• Field-based measurements offer a potential alternative for determining individual optimal cadence.

Purpose of the Study:

• To demonstrate that optimal cadence can be identified using field-measured data.
• To present a methodology for calculating optimal cadence from training and racing data.

Main Methods:

• Collected field data on power output, heart rate, and cadence during cycling sessions.
• Applied a non-linear regression model to relate power output to cadence and heart rate.
• Identified optimal cadences for individual cyclists.

Main Results:

• Optimal cadences were determined for two cyclists (83 and 70 rpm), closely matching their preferred cadences.
• Power output decreased by approximately 6% at cadences 20 rpm above or below the optimum.
• The study validates a field-based approach to optimal cadence determination.

Conclusions:

• Optimal cycling cadence can be determined without laboratory intervention.
• Riders can use this methodology with sufficient field data (>6 months) and appropriate calculations.
• This approach empowers cyclists to personalize their performance optimization strategies.
