Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Based on the known occurrence of hyponatremia in marathon runners, participants of the Ironman European Championship between the years 2005 and 2014 were screened for the occurrence of hyponatremia after finishing the race for safety reasons. Subjects were approached at random in the athlete's garden and invited to participate. All participants were 18 years or older.
