Abstract
Pro posouzení prevalence cvičení spojené s hyponatrémie (EAH) ve dvou 24 hodin na horském kole (MTB) (R1, R2), jeden 24-hodinový běh (R3) a jeden multi-stage MTB (R4) závody konané v České republice republika ve shluku čtyř průřezových studií. Metody: Příjem tekutin, změny v tělesné hmotnosti, hematokritu, objemu plazmy, plazma [Na +], plazma [K +], plasma osmolality, moč [na +], moč [K +], moč specifická hmotnost, osmolalita moči, K + / na + poměr v moči, transtubular gradient draslíku a glomerulární filtrace byly měřeny a vypočteny. Používání nesteroidních protizánětlivých léků a příznaky EAH byly zaznamenány pomocí post-race dotazníků.
To assess the prevalence of exercise-associated hyponatremia (EAH) in two 24-hour mountain bike (MTB) (R1,R2), one 24-hour running (R3) and one multi-stage MTB (R4) races held in the Czech Republic in a cluster of four cross-sectional studies. Methods: In 27 ultra-mountain bikers (ultra-MTBers), 12 ultra-runners, and 14 multi-stage MTBers, fluid intake, changes in body mass, hematocrit, plasma volume, plasma [Na+], plasma [K+], plasma osmolality, urine [Na+], urine [K+], urine specific gravity, urine osmolality, K+/Na+ ratio in urine, transtubular potassium gradient and glomerular filtration rate were measured and calculated. The use of non-steroidal anti-inflammatory drugs and symptoms of EAH were recorded using post-race questionnaires.
