Rhabdomyolysis and exercise-associated hyponatremia in ultra-bikers and ultra-runners. There are information for a connection between load-induced hyponatremia, rhabdomyolysis and renal failure in extreme duration loads. This has been studied and confirmed by the majority of ultra-raptures. We have now examined in 7 different ultra races whether this connection can be confirmed in other disciplines.We found a rhabdomyolysis at 2 hyponatriemic and 4 Normonatriemic runners.
There were no kidney problems for all runners. The whole work can be read below https://pubmed.ncbi.nlm.nih.gov/26113805/
