A "Blood Pass" system can detect illegal performance enhancement in athletes. Hematological values in elite athletes remain stable, forming a physiological basis for this anti-doping system.

Area of Science:

  • Sports Science
  • Anti-Doping
  • Hematology

Background:

  • Athletes manipulate oxygen-carrying capacity for enhanced performance.
  • Detecting these illegal methods is crucial for fair competition.

Purpose of the Study:

  • To establish a "Blood Pass" system for detecting blood manipulation.
  • To assess the stability of hematological values in elite athletes over time.

Main Methods:

  • Collected venous blood samples from 47 elite athletes across four time points.
  • Measured hematological values and calculated ON(hes) and OFF(hre) values.
  • Collected data via questionnaire on training and lifestyle factors.

Main Results:

  • Individual hematological values showed some variation.

  • Median hematological values, including ON(hes) and OFF(hre), remained stable within 95% confidence limits.
  • No significant gender differences were observed.

    • Conclusions:

    • Median hematological factors are stable over time in elite athletes.
    • There is a physiological basis for an individual-based "Blood Pass" system.
    • This system can help identify potential hemoglobin and red cell mass manipulation.
