Vertikaalihyppyjen voimantuoton yhteys m\u00e4kihypyn ponnistuksen tehokkuuteen. Biomekaniikka, Pro gradu -tutkielma, Liikuntabiologian laitos, Jyv\u00e4skyl\u00e4n yliopisto, 78 s.\r\n\r\nPonnistusta pidet\u00e4\u00e4n m\u00e4kihyppysuorituksen t\u00e4rkeimp\u00e4n\u00e4 osa-alueena, mink\u00e4 johdosta biomekaaninen tutkimus on painottunut t\u00e4m\u00e4n osa-alueen ymp\u00e4rille. Vertikaalihypyill\u00e4 on keskeinen rooli m\u00e4kihypp\u00e4\u00e4j\u00e4n fyysist\u00e4 suorituskyky\u00e4 mittaavassa testist\u00f6ss\u00e4, ja tyypillisesti my\u00f6s oheisharjoittelussa painotetaan nousukorkeuden kehitt\u00e4mist\u00e4. Tutkimustiedon mukaan vertikaalihyppyjen nousukorkeus ei kuitenkaan ole paras mittari lajeissa, joissa voimantuottoon k\u00e4ytett\u00e4v\u00e4 aika on lyhyt. M\u00e4kihyppytutkimuksesta ei l\u00f6ydy selkeit\u00e4 kuvauksia siit\u00e4, miten kineettiset muuttujat vertikaalihypyiss\u00e4 selitt\u00e4v\u00e4t lajiponnistuksen voimantuottoa. My\u00f6s lajitekniikan yhteys voimantuottoon on j\u00e4\u00e4nyt tutkimuksessa v\u00e4hemm\u00e4lle huomiolle. \r\n\r\nT\u00e4ss\u00e4 tutkimuksessa selvitettiin, miten m\u00e4kihypp\u00e4\u00e4jien voimantuotto vertikaalihypyiss\u00e4 on yhteydess\u00e4 lajiolosuhteisiin, ja siten suorituksen tehokkuuteen. Lis\u00e4ksi tutkimuksessa tarkasteltiin lajiteknisten muuttujien korrelaatiota voimantuottoon ja kokonaissuorituksen laatuun. Tutkimuskysymysten kautta pyrittiin ymm\u00e4rt\u00e4m\u00e4\u00e4n paremmin lajinomaisen tehoharjoittelun merkityst\u00e4, sek\u00e4 selkiytt\u00e4m\u00e4\u00e4n lajisuorituksen biomekaanisia laatutekij\u00f6it\u00e4. Mittaukset suoritettiin kansallisen kilpailun yhteydess\u00e4 (n = 19\u201320), jossa kineettisi\u00e4 parametreja mitattiin voimalevyill\u00e4 ja kinemaattisia parametreja videoanalyysiin perustuen. Staattisen hypyn nousukorkeus korreloi merkitsev\u00e4sti vain keulan keskivaiheen (2\u20134 m) voimantuoton kanssa (r = 0,516, p = 0,024*). Sen sijaan hypyn pituutta selittiv\u00e4t eniten hyv\u00e4 voimantuotto sek\u00e4 hyppyrin keulan ensimm\u00e4isell\u00e4 (0\u20132 m) ett\u00e4 toisella (2\u20134 m) kolmanneksella (r = 0,647, p = 0,003**, r = 0,608, p = 0,006**). Laskuasennon, ponnistusvaiheen tai alkuilmalennon kinematiikasta l\u00f6ytyi hyvin v\u00e4h\u00e4n muuttujia, joilla voitiin selitt\u00e4\u00e4 suorituksen laatua ryhm\u00e4tasolla. \r\n\r\nTutkimuksen keskeiset johtop\u00e4\u00e4t\u00f6kset olivat: 1) Hyv\u00e4 staattisen hypyn nousukorkeus auttaa tehokkaan voimantuoton saavuttamisessa, mutta ei selit\u00e4 kokonaan voimantuot-tokyky\u00e4 lajiolosuhteissa. 2) Lajiponnistuksen hyv\u00e4 voimantuotto, ja erityisesti sen en-simm\u00e4isen puolikkaan tehokkuus vaikuttaa olevan ratkaisevaa suorituksen laadun kan-nalta. 3) Hyv\u00e4 suoritus ja tehokas voimantuotto on mahdollista toteuttaa erilaisilla tekniikoilla. Valmentajien, urheilijoiden ja testaajien tulisikin pohtia, miten laji- ja oheisharjoittelulla voitaisiin tehostaa yksil\u00f6llist\u00e4 voimantuottokyky\u00e4 lajiolosuhteissa, sek\u00e4 kehitt\u00e4\u00e4 testimenetelmi\u00e4 jotka vastaavat biomekaanisessa tarkastelussa paremmin lajiponnistuksen yksil\u00f6llisi\u00e4 piirteit\u00e4.", "language": "fi", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Lauri Hakola (lajohako) on 2016-06-01 19:19:38.430232.
