Acute renal failure & Rhabdomyolysis
Our actions & our advice
The kidneys
and muscles
are essential
for sports.
The muscle produces waste and the kidney eliminates it. The destruction of muscle can clog the kidneys. Without the kidneys the body quickly stops working

Understanding the interactions between these two organs is necessary. The kidneys can almost shut down without causing symptoms, and life is at risk. You have to be aware of that. In addition, it is necessary to advance medical research to better warn you of the dangers.
We finance medical studies
dedicated to this problem in sport
to better prevent & act.
Our medical research
Acute renal failure
- Study: Acute kidney injury in trail running
- Acute renal failure (AKI) is generally observed after ultra races, with a prevalence of up to 80%. Severe cases are rare, but they do happen. What does this mean for the runner? Can he continue to run in the future?
