20.500.12556/RUL-190694 Povezanost med izločanjem nevrotrofnega faktorja možganskega izvora in rezultati Stroopovega testa po vadbeni enoti za razvoj moči Association between brain-derived neurotrophic factor secretion and stroop test results following a strength training session Namen magistrske naloge je bil raziskati povezanost med spremembami koncentracij nevrotrofnega faktorja možganskega izvora (BDNF) in rezultati Stroopovega barvnega in besednega testa po vadbeni enoti za razvoj moči. V raziskavi je sodelovalo 17 zdravih zmerno telesno dejavnih moških, starih med 18 in 30 let. Meritve so potekale v Kineziološkem laboratoriju na Fakulteti za šport Univerze v Ljubljani. Preizkušanci so izvedli protokol vadbene enote za razvoj moči, ki je vključeval štiri serije do mišične odpovedi z 2-minutnimi odmori med serijami in vajami. Primerjali smo ga s kontrolnim protokolom brez vadbe. Oba protokola sta vključevala Stroopov test, preizkušancem pa je bil v dveh časovnih točkah odvzet vzorec krvi za določitev koncentracije BDNF. Rezultati so pokazali izboljšanje pri vseh pogojih Stroopovega testa po obeh protokolih, pri čemer je bila največja relativna sprememba ugotovljena pri inkongruentnem pogoju. Relativne spremembe rezultatov Stroopovega testa so bile večje pri protokolu vadbene enote za razvoj moči v primerjavi s kontrolnim protokolom. Koncentracija BDNF se je statistično značilno povečala tako po protokolu vadbe za razvoj moči kot po kontrolnem protokolu. Med relativnimi spremembami rezultatov Stroopovega testa in relativnimi spremembami ravni BDNF po kontrolnem protokolu ni bilo statistično značilne povezanosti. Med relativnimi spremembami rezultatov posameznega pogoja Stroopovega testa in relativno spremembo ravni BDNF v krvi po protokolu vadbene enote za razvoj moči smo pričakovali pozitivno povezanost, vendar rezultati niso pokazali statistično značilnih povezav. Zato lahko sklepamo, da je bilo izboljšanje kognitivnega delovanja najverjetneje posledica tudi drugih mehanizmov. The aim of this master's thesis was to investigate the association between changes in brain-derived neurotrophic factor (BDNF) concentration and Stroop Color and Word Test performance following a strength training session. Seventeen healthy, moderately physically active men aged 18 to 30 years participated in the study. All measurements were conducted in the Kinesiology Laboratory at the Faculty of Sport, University of Ljubljana. Participants completed a strength training protocol consisting of four sets performed to muscular failure with 2-minute rest intervals between sets and exercises, which was compared with a control protocol involving no exercise. Both protocols included administration of the Stroop test, and blood samples were collected at two time points to determine BDNF concentrations. The results showed improved performance across all Stroop test conditions following the interventions, with the greatest relative improvement observed in the incongruent condition. Relative changes in Stroop test performance were greater following the strength training protocol than after the control protocol. BDNF concentrations increased significantly after both the strength training and the control protocol. No statistically significant associations were found between the relative changes in Stroop test performance and the relative changes in BDNF concentration following the control protocol. Although a positive association between the relative changes in Stroop test performance and the relative changes in BDNF concentration was hypothesized following the trength training protocol, no statistically significant relationships were observed. The improvement in cognitive performance was therefore most likely mediated by other mechanisms than changes in circulating BDNF concentration.
