| Description | The aim was to assess the prevalence of exercise-associated hyponatremia (EAH) in ultra-enduance athletes in the Czech Republic in a cluster of four cross-sectional studies in two 24-hour mountain bike (MTB) races (R1,R2), one 24-hour running race (R3) and one multi-stage MTB race (R4). Methods In 27 ultra-mountain bikers (ultra-MTBers), 12 ultra-runners, and 14 multi-stage MTBers, fluid intake, changes in body mass (BM), hematocrit, plasma volume (PV), plasma [Na+], plasma [K+], plasma osmolality, urine [Na+], urine [K+], urine specific gravity (USG), urine osmolality, K+/Na+ ratio in urine, transtubular potassium gradient (TTKG) and glomerular filtration rate (GFR) were measured and calculated. The use of non-steroidal antiinflammatory drugs (NSAIDs) and symptoms of EAH were observed post-race. |
