Science and sport once again meet in a field where human limits are measured in meters of depth and seconds of endurance. AIDA International has released a new medical and scientific report that not only highlights key advances in freediving research, but also reveals how high performance continues to push complex questions about the human body. In an environment where every descent involves invisible risks, the need to understand what happens beneath the surface is becoming increasingly urgent.

This new report does not simply present isolated results, but instead offers a broader perspective on safety, health, and the regulation of the sport. From studies conducted under real competition conditions to updates in medical standards and anti-doping protocols, the work reflects a coordinated effort to support the evolution of freediving with solid scientific tools. At the intersection of performance and care, research is beginning to outline a clearer map of the physiological challenges of high performance.

Science at depth: what the body reveals under pressure

One of the most significant aspects of the report is the publication of an AIDA-funded study in the European Journal of Applied Physiology, providing new evidence on how the body responds to depth training. Conducted in Dahab, Egypt, this study stands out for being carried out in real competition conditions, moving away from controlled laboratory environments to observe how elite divers’ bodies react in authentic scenarios.

The results show a progressive inflammatory and oxidative response associated with repeated dives, a finding that raises new questions about the cumulative impact of extreme training. Among the tools used, ultrasound detection of vascular gas embolisms stands out as a key element in understanding the risk of decompression sickness in freedivers. This multiparametric approach not only expands existing knowledge, but also brings science closer to the athlete’s real experience, where every variable can make a difference.

New standards and the challenge of protecting the athlete

The report also focuses on updating essential documents for the safe development of high-level competitions. The AIDA Medical and Scientific Committee has revised guidelines covering everything from required medical equipment to specific contraindications for freediving, integrating knowledge from specialists across different countries and disciplines. These updates reflect a constant concern for anticipating risks in a sport where conditions can change in a matter of seconds.

In addition, new recommendations for variable weight world record attempts—one of the most demanding freediving disciplines—have been introduced, along with strengthened anti-doping programs. The ongoing training of control officers, beyond major events, demonstrates a sustained commitment to the integrity of the sport. In this balance between exploring human limits and safeguarding health, AIDA continues to build a framework that seeks to address, without oversimplifying, the complexity of deep diving.
