The incidence of exercise-associated hyponatremia (EAH) is higher in women than in men. We present three cases of a very mild post-race EAH in female winners of three 24-h ultra races in various weather conditions and disciplines with post-race plasma sodium levels of 134 mmol/L (Case 1), 133 mmol/L (Case 2) and 134 mmol/L (Case 3). Moreover, Case 1 and Case 2 showed elevated creatine kinase concentrations of 10,000 U/L with an absence of renal function abnormality. The common characteristics were female sex, veteran recreational category, long race experience in the particular sports discipline, excellent race performance, similar total weekly training hours and the presence of luteal phase of the menstrual cycle during the race. Hematocrit and hemoglobin decreased and post-race K+/Na+ ratio in urine increased in all three cases. In addition, an increased body mass and decreased urine specific gravity and urine osmolality suggested over-drinking in Case 1. We recommend that race medical personnel should not forget to look for EAH even in fast and experienced female athletes and during races in different environmental conditions.

Výskyt cvičením způsobené hyponatrémie (EAH) je vyšší u žen než u mužů. Představujeme tři případy velmi mírné EAH u tří vítězek 24-h ultra závodů v různých povětrnostních podmínkách a disciplínách. Pozávodní hladina sodíku [Na +] v plasmě činila 134 mmol/L (případ 1), 133 mmol/L (případ 2) a 134 mmol/L (případ 3). Navíc případ 1 a případ 2 prokázali zvýšení kreatinkinázy v koncentracích větších než 10 000 U/L s absencí abnormální funkce ledvin.
