The international media has raised the issue of the possible use of injectable hyaluronic acid by athletes in ski jumping. Theoretically, the impact of changes in soft tissue parameters on the compliance of equipment with established regulations has been discussed.
It is important to emphasise that hyaluronic acid is not included in the World Anti-Doping Agency (WADA) list of prohibited substances, as it has no pharmacological effect on endurance, strength, reaction speed or tissue oxygenation.
From a scientific point of view, hyaluronic acid is a natural glycosaminoglycan of the extracellular matrix, present in the skin, connective tissue and synovial fluid.
Biological properties of hyaluronic acid
Hyaluronic acid:
- is highly hydrophilic and capable of binding water molecules in a volume hundreds of times greater than its own mass
- participates in the formation of the extracellular matrix
- supports the mechanical stability of tissues
- provides a reversible volumetric effect due to its physicochemical properties rather than pharmacological effects
After injection, stabilised hyaluronic acid forms a three-dimensional gel structure. The volume is created mechanically, without stimulating the body’s hormonal or metabolic activity.
Biodegradation occurs gradually under the action of hyaluronidases and natural metabolic processes.

Regulatory and evidence-based aspects
Injectable hyaluronic acid has been used for over 20 years in:
• dermatology
• orthopaedics
• ophthalmology
• reconstructive surgery
• aesthetic medicine
Its safety has been confirmed by clinical studies, and its risk profile has been well studied. When administered in accordance with protocols, the drug demonstrates predictable distribution and a controlled resorption period.
Hyaluronic acid does not alter an athlete’s physiological parameters or enhance the body’s biomechanical capabilities. The topic discussed in the media concerns only the hypothetical effect on anthropometric parameters, not pharmacological doping.
