20.500.12556/RUL-185038 Ekscentrično-kvazi-izometrična vadba pregled raziskav o biomehanskih značilnosti in akutnih učinkih Eccentric-quasi-isometric training A review of biomechanical characteristics and acute effects Ekscentrična kvaziizometrična (EKI) vadba je razmeroma nova metoda vadbe proti uporu, pri kateri se submaksimalna izometrična kontrakcija kombinira z maksimalnim ekscentričnim upiranjem. Namen prispevka je pregledati razpoložljivo znanstveno literaturo o EKI-vadbi in povzeti dozdajšnje ugotovitve. V pregled smo vključili šest študij, ki so obravnavale akutne učinke EKI-kontrakcij na biomehanske, mišičnoaktivacijske in morfološke spremenljivke. Večina raziskav je bila izvedena na mladih odraslih ter je vključevala iztegovalke in upogibalke kolena ter upogibalke komolca. Ugotovljene so bile razlike v utrujenosti po EKI-vadbi, pri času pod napetostjo, navoru in mišični aktivaciji glede na spol in mišično skupino med EKI. V primerjavi s klasično ekscentrično in izotonično vadbo je EKI povzročila manj zapoznele mišične bolečine in s tem povezanih negativnih sprememb kljub enaki kumulativni mehanski obremenitvi. Kljub obetavnim rezultatom je področje še vedno slabo raziskano. Za celovito razumevanje učinkov in morebitne uporabe EKI-vadbe v športu, rehabilitaciji in preventivi so potrebne dodatne raziskave. Eccentric Quasi-Isometric (EQI) training is a relatively new approach to resistance training that combines submaximal isometric contraction with maximal eccentric resistance. The purpose of this paper is to review the existing scientific literature on EQI training and summarize the current findings. Six studies examining the acute effects of EQI contractions on biomechanical, muscle activation, and morphological variables were included in the review. Most research was conducted on young adults and involved knee extensors, biceps brachii, and knee flexors. Differences in fatigue, time under tension, torque, and muscle activation were reported depending on gender and muscle group. Compared to traditional eccentric and isotonic training, EQI caused less delayed-onset muscle soreness and associated negative changes, despite the same cumulative mechanical load. Despite promising results, the field is still under-researched. Further studies are needed for a comprehensive understanding of the effects and potential applications of EQI training in sports, rehabilitation, and prevention. šport ekscentrična vadba kvaziizometrična kontrakcija mišična aktivacija biomehanika utrujenost rehabilitacija odpornost proti poškodbam sport eccentric training quasi-isometric contraction muscle activation biomechanics fatique rehabilitation injury resiliance true false true Slovenski jezik Angleški jezik Članek v reviji 2026-07-21 12:09:30 2026-07-21 12:09:32 2026-07-22 04:04:18 0000-00-00 00:00:00 2025 0 0 Str. 168-174 št. 1/2 Letn. 73 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.01 3024-0603 10.52165/sport.73.1-2.168-174 249169667 revija+1-2+2025_24-licen_168-174_ok.pdf revija+1-2+2025_24-licen_168-174_ok.pdf 1 9897B0628D636D71623DCFC568771A11 489371c4bea422a743bdb4b20c894213a83b19f201904a2bfdb356d4c1a9343d 3822d11e-84ee-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=243064 https://journals.uni-lj.si/sport/article/view/22283 0 074e2fb3-84ec-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=243061 Fakulteta za šport Šport 0 0 0
