Ergogenic aids: human growth hormone

Area of Science:

• Endocrinology
• Sports Medicine
• Pharmacology

Background:

• Human growth hormone (GH) has established medical applications.
• GH is increasingly misused by athletes as an ergogenic aid for performance enhancement.
• The use of GH and anabolic steroids in sports is a significant concern for athletes, parents, and policymakers.

Purpose of the Study:

• To review the physiology and medical uses of GH.
• To assess the efficacy of GH as an ergogenic aid in athletic performance.
• To discuss the development of methods for detecting illicit GH use in sports.

Main Methods:

• Literature review of GH physiology, medical indications, and ergogenic effects.
• Analysis of scientific studies on GH's impact on exercise performance and work capacity.
• Overview of current and developing techniques for detecting GH doping.

Main Results:

• Supraphysiologic doses of GH can induce lipolysis and increase muscle volume.
• Scientific literature provides limited compelling evidence for GH's efficacy as an ergogenic aid due to ethical study limitations.
• Isolated studies suggest potential for improved athletic performance and anti-aging effects.

Conclusions:

• GH has a reputation among athletes for performance enhancement despite insufficient scientific validation.
• International efforts are underway to detect illegal GH doping, with promising techniques emerging.
• Further research is needed to clarify GH's true ergogenic potential and risks.
