Question 1

What is the Meaning of Athlete Biological Passport?

Accepted Answer

The Athlete Biological Passport represents an individualized electronic record compiling an athlete's biological markers over time, primarily focusing on hematological and steroidal parameters. This comprehensive profile serves as a baseline for an individual's unique physiological fluctuations, allowing for the detection of atypical deviations that may indicate the use of prohibited substances or methods. Its core purpose is to foster fair competition and protect athlete health by identifying patterns inconsistent with normal physiological function.

Question 2

What is the Context of Athlete Biological Passport?

Accepted Answer

Operating within the broader framework of anti-doping initiatives, the Athlete Biological Passport incorporates principles of human physiology and endocrinology to establish an individual's normal biological range. It monitors parameters directly influenced by erythropoiesis and steroidogenesis, key processes within the body's homeostatic mechanisms. This systematic approach allows for a sophisticated assessment of an athlete's physiological state, distinguishing between natural variations and those induced by external manipulation.

Question 3

What is the Significance of Athlete Biological Passport?

Accepted Answer

The Athlete Biological Passport holds significant importance in upholding the integrity of sport and safeguarding athlete well-being. By establishing an individual's physiological baseline, it enables the identification of subtle, yet suspicious, shifts in biomarkers that might otherwise go unnoticed. This method serves as a deterrent to doping practices and indirectly protects athletes from the adverse health consequences associated with performance-enhancing drug use, contributing to a fairer and healthier competitive environment.

Question 4

What is the Mechanism of Athlete Biological Passport?

Accepted Answer

The mechanism of the Athlete Biological Passport relies on the principle of longitudinal data analysis, comparing an athlete's current biological values against their own historical profile rather than population averages. It comprises two primary modules: the hematological module tracks parameters like hemoglobin and reticulocytes, indicative of erythropoietic activity, while the steroidal module monitors endogenous steroid profiles, such as testosterone to epitestosterone ratios. Statistical algorithms assess the probability that observed deviations fall outside an individual's established physiological range, triggering further investigation if anomalies are detected.

Question 5

What is the Application of Athlete Biological Passport?

Accepted Answer

In practice, the Athlete Biological Passport is a fundamental element of modern anti-doping strategies implemented by sports federations and anti-doping organizations worldwide. It involves regular collection of blood and urine samples from athletes, which are then analyzed to populate their individual passport. This continuous monitoring allows for the detection of subtle physiological adaptations over time, providing a powerful tool for identifying potential doping violations without necessarily detecting the prohibited substance itself. The ABP also guides targeted testing, optimizing resource allocation.

Question 6

What is the Metric of Athlete Biological Passport?

Accepted Answer

The effects monitored by the Athlete Biological Passport are quantified through specific laboratory analyses of blood and urine samples. Key hematological metrics include hemoglobin concentration, reticulocyte percentage, and calculated indices like the Off-Score, which collectively reflect red blood cell turnover and erythropoietic stimulation. Steroidal measurements involve gas chromatography-mass spectrometry to determine ratios of endogenous steroids, such as testosterone to epitestosterone (T/E ratio) and other androgen metabolites, providing insight into the integrity of the athlete's natural hormonal profile.

Question 7

What is the Risk of Athlete Biological Passport?

Accepted Answer

While the Athlete Biological Passport is a diagnostic tool for anti-doping, not a medical intervention, its improper application or misinterpretation carries specific risks. A primary concern is the potential for false positives, where natural physiological variations or medical conditions might be mistakenly identified as doping, leading to undue accusations and significant personal distress for the athlete. Additionally, privacy of sensitive medical data is paramount, requiring robust protection protocols. Mismanagement of the data or insufficient expert review could compromise the fairness and accuracy of the anti-doping process.
