Cycling training experience significantly improves gross mechanical efficiency (GME) in cyclists. Trained cyclists demonstrate higher GME compared to untrained individuals across various workloads, highlighting training

Area of Science:

  • Exercise Physiology
  • Sports Science
  • Biomechanics

Background:

  • Gross mechanical efficiency (GME) in cycling is a key performance indicator.
  • Existing literature presents conflicting findings on the impact of cycling experience on GME.

Purpose of the Study:

  • To investigate and quantify differences in GME between trained and untrained cyclists.
  • To determine if cycling training experience is a significant factor influencing GME.

Main Methods:

  • Thirty-two participants (16 trained, 16 untrained) underwent two cycling efficiency tests.
  • Tests included relative workloads (50%, 60% Wmax) and a fixed workload (150 W) on an ergometer.
  • Gross mechanical efficiency (GME) was calculated from gas exchange data at preferred cadence.

Main Results:

  • Trained cyclists exhibited significantly higher GME compared to untrained cyclists (+1.4%, p=0.03).
  • At 60% Wmax, GME was significantly lower than at 150 W (p=0.04).
  • No significant GME difference was observed between 60% Wmax and 50% Wmax workloads.

Conclusions:

  • Cycling training experience demonstrably influences gross mechanical efficiency.
  • Trained cyclists are more mechanically efficient than their untrained counterparts.
  • Training status is a crucial variable to consider in future cycling efficiency research.
