In addition to their effects on regulating the menstrual cycle and pregnancy, taking these contraceptives may also influence their physical performance. Therefore, we conducted a review to examine the impact of hormonal contraceptive use on performance in female endurance athletes. Due to the high heterogeneity in both the design and results of individual studies, we specifically analysed studies comparing a group taking hormonal contraceptives and a group with regular menstruation; studies comparing results before and after taking hormonal contraceptives; and studies comparing specific measured parameters at different phases of the cycle. Overall, we found trends indicating changes in performance after a prolonged period of hormonal contraceptive use; most evidence points to a decrease in peak oxygen concumption, but the effects are trivial and results between studies are too varied so we cannot speak with certainty about the impact of contraceptive use on athletic performance. Further research is needed for more accurate understanding of the impact of hormonal contraceptives and to provide definitive conclusions</dc:description><dc:description xml:lang="sl">Hormonske kontraceptive v obliki tablet uporablja veliko žensk po vsem svetu. Poleg učinkov na uravnavanje menstrualnega cikla in nosečnosti lahko jemanje teh sredstev vpliva tudi na njihovo telesno zmogljivost. Zato smo opravili pregled znanstvene literature, da bi proučili vpliv uporabe hormonskih kontraceptivov na zmogljivost vzdržljivostnih športnic. Zaradi velike heterogenosti tako v zasnovi kot rezultatih posameznih študij smo posebej analizirali: študije, v katerih so primerjali skupino, ki je jemala hormonske kontraceptive, s skupino z redno menstruacijo; študije, v katerih so primerjali rezultate pred jemanjem hormonskih kontraceptivov in po njem; ter študije, v katerih so primerjali posamezne merjene parametre v različnih fazah cikla. V splošnem smo ugotovili, da trendi kažejo na spremembe v zmogljivosti po dolgotrajnem obdobju jemanja hormonskih kontraceptivov; največ dokazov kaže na znižanje najvišje vrednosti porabe kisika med obremenilnim testom, vendar so učinki majhni in rezultati posameznih študij preveč različni, zato ne moremo z gotovostjo govoriti o vplivu jemanja kontraceptivov na zmogljivost. Za natančnejše razumevanje vplivov in dokončne zaključke je potrebno dodatno raziskovanje</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-KMVUSCKW"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-KMVUSCKW" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-KMVUSCKW/23224b05-56a4-42e2-99a1-defbecaa05ba/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za šport</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-KMVUSCKW/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-KMVUSCKW" /></ore:Aggregation></rdf:RDF>
