Hyponatremia Clinical Trial
Official title:
Acid-base and Electrolyte Balance Among Triathletes in the Ironman European Championship
Aim of the study is examining the incidence of the occurrence of hyponatremia during a Triathlon
Studies in similar endurance sports (e.g. marathon) could already indicate a high incidence
for the appearance of hyponatremia during competitions. The loss of sodium through sweating
and the excessive fluid intake during the competitions is a primary risk factor for the
development of hyponatremia.
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.
