20.500.12556/RUL-189334 Ocena dehidracije pri nogometaših v realnih tekmovalnih razmerah The assessment of dehydration in football players during real-life competition Namen magistrskega dela je bil oceniti hidracijsko stanje nogometašev v realnih razmerah ter preveriti uporabnost merjenja telesne mase za oceno hipohidracije. V raziskavo je bilo vključenih 18 nogometašev. Meritve so bile izvedene med treningom v tekmovalnem obdobju. Hidracijsko stanje nogometašev smo ocenjevali z merjenjem telesne mase pred in po treningu, določanjem specifične teže urina z refraktometrom in testnimi lističi ter spremljanjem vnosa vode in izgub vode med treningom. Povprečna skupna izguba vode je znašala 0,80 ± 0,34 L, povprečen vnos tekočine med treningom pa 0,21 ± 0,19 L. Pri 16 od 18 nogometašev izgubljena tekočina med treningom ni bila v celoti nadomeščena, saj je povprečna nenadomeščena količina vode znašala 0,59 ± 0,33 L. Povprečna relativna izguba vode je znašala 1,11 ± 0,52 % telesne mase, pri enem nogometašu pa je presegla 2 %. Primerjava metod za določanje specifične teže urina je pokazala, da sta refraktometer in testni lističi pri 15 od 18 nogometašev zaznala spremembo v isti smeri. Rezultati kažejo, da med treningom prihaja do izgub vode, ki pri večini nogometašev niso v celoti nadomeščene, zato obstaja tveganje za razvoj hipohidracije. Merjenje telesne mase se je izkazalo kot uporabna in praktična metoda za spremljanje sprememb hidracijskega stanja nogometašev. The aim of this master's thesis was to assess the hydration status of soccer players under real training conditions and to evaluate the usefulness of body mass measurements for assessing dehydration. The study included 18 soccer players. Measurements were conducted during a training session in the competitive season. Hydration status was assessed with body mass measurements before and after training, determination of urine specific gravity with a refractometer and urine test strips, and monitoring of fluid intake and water losses during training. The average total water loss amounted to 0.80 ± 0.34 L, while the average fluid intake during training was 0.21 ± 0.19 L. In 16 of the 18 soccer players, fluid losses during training were not fully replaced, as the average uncompensated fluid loss amounted to 0.59 ± 0.33 L. The average relative total water loss was 1.11 ± 0.52 % of body mass, with one player exceeding 2 %. Comparison of the methods used to determine urine specific gravity demonstrated that the refractometer and urine test strips detected changes in the same direction in 15 of the 18 players. The results indicate that water losses occurring during training are often not fully compensated, which may increase the risk of hypohydration. Body mass measurement proved to be a useful and practical method for monitoring changes in hydration status in soccer players. nogometaši hidracija dehidracija specifična teža urina telesna masa soccer players hydration dehydration urine specific gravity body mass true false false [Ž.
