Izokinetična ocena jakosti mišic stegna pri hokejistihPrusnik, RokRaziskovali smo mišično jakost nog, natančneje stegna. Mišično jakost smo merili na izokinetičnem dinamometru Technogym Rev 9000. Ob koncu tekmovalne sezone 2009/10 smo obravnavali 36 hokejistov (11 ... članov, 13 mladincev in 12 kadetov). Izmerili smo maksimalni navor za štiriglavo stegensko mišico v koncentrični in zadnjo ložo stegna v koncentrični in ekscentrični kontrakciji. Maksimalne navore smo normalizirali glede na telesno maso preizkušancev in izračunali mišična razmerja: HQR in dinamično razmerje DFR. Ugotovili smo, da so bile statistično pomembne razlike v jakosti obeh štiriglavih stegenskih mišic in leve zadnje lože stegna v koncentričnem načinu dela. Iz rezultatov je razvidno, da so bile med mladinci in kadeti večje razlike v jakosti stegenskih mišic, kakor med mladinci in člani. Iz obeh medmišičnih razmerij je razvidno, da imajo najprimernejše razmerje kadeti, od tega se malce oddaljijo mladinci, najbolj pa člani, ki imajo izrazito prešibko zadnjo ložo stegna v odnosu do štiriglave stegenske mišice. S splošnim testom gibljivosti smo ugotovili, da imajo kadeti slabšo gibljivost v merjenem predelu od mladincev in članov. Rezultati o gibljivosti in jakosti mišic ter izračuni medmišičnih razmerij so nam dali pomembne informacije o telesni pripravljenosti, hkrati pa so dober pokazatelj nevarnosti tveganja za poškodbo predvsem kolenskega sklepa in stegenskih mišic.Source: Šport : revija za teoretična in praktična vprašanja športa. - ISSN 0353-7455 (Letn. 60, št. 3/4, 2012, str. 146-154)Type of material - article, component partPublish date - 2012Language - slovenianCOBISS.SI-ID - 4313265
