Human growth hormone doping in sport

Area of Science:

• Sports Science
• Biochemistry
• Anti-Doping Research

Background:

• Recombinant human growth hormone (rhGH) has been a banned substance since the 1990s.
• Its use in sports is suspected for anabolic effects and performance enhancement, often in combination with other doping agents.
• Detection is difficult due to the similarity between endogenous and recombinant forms, pulsatile secretion, and inter-individual variability.

Purpose of the Study:

• To provide an overview of human growth hormone (hGH) in relation to sports.
• To evaluate current methods for detecting hGH doping.
• To discuss the challenges in identifying rhGH misuse in athletes.

Main Methods:

• Literature review on hGH, exercise, adverse effects, and doping detection methods.
• Evaluation of indirect and direct detection approaches for rhGH.

Main Results:

• Exercise influences hGH production, complicating doping analysis.
• Both indirect and direct analytical methods face challenges in proving rhGH misuse.
• The direct method offers better reliability but has a limited detection window.

Conclusions:

• hGH doping presents a significant challenge in anti-doping efforts.
• The short half-life and exercise-induced effects on hGH complicate detection.
• Direct immunoassay methods are currently the most promising for detecting rhGH doping.
