Brief summary
Aim of the study is examining the incidence of the occurrence of hyponatremia during a Triathlon
Detailed description
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.
Interventions
BEHAVIORALEducation in nutrition
Athletes were given a 45 min lesson on the proper diet and fluid intake to prevent hyponatremia in long-distance triathlon.
