Area of Science:

  • Exercise Physiology
  • Sports Science
  • Biostatistics

Background:

  • Accurate determination of physiological thresholds is crucial for optimizing athletic training.
  • Existing methods for identifying the heart-rate threshold (HRT) may lack objectivity.
  • Cyclists benefit from precise training zones to enhance performance and prevent overtraining.

Purpose of the Study:

  • To establish an objective method for identifying the heart-rate threshold (HRT) in cyclists.
  • To validate this new HRT identification method against established physiological markers.
  • To provide cyclists with a reliable tool for setting training intensity.

Main Methods:

  • Fifty-six male cyclists performed incremental cycle ergometer tests to volitional fatigue.

  • Heart-rate threshold (HRT) was identified using a novel logarithmic regression analysis.
  • Ventilatory threshold (VT) and lactate threshold (HLaT) were measured as criterion validation markers.

    • Main Results:

    • The novel HRT method demonstrated significant associations with both VT and HLaT (r = 0.98).
    • Statistical analysis revealed no significant variance between the identified HRT, VT, and HLaT.
    • The logarithmic regression approach proved to be an objective means for HRT determination.

    Conclusions:

    • The logarithmic regression method offers an objective and validated approach to determine the heart-rate threshold in cyclists.
    • This method provides cyclists with reliable data for establishing personalized training levels and protocols.
    • Objective HRT identification can lead to more effective and targeted endurance training programs.
