Lajispesifisen voimaharjoittelun vaikutus pes\u00e4pallon ly\u00f6ntisuoritukseen. Liikuntabiologian laitos, Jyv\u00e4skyl\u00e4n Yliopisto. Valmennus- ja testausopin Pro Gradu-tutkielma 56s.\n\nLajispesifisen voimaharjoittelun tarkoitus on saada aikaan vastaavanlaisia \u00e4rsykkeit\u00e4, mit\u00e4 itse kilpailusuoritus aiheuttaa. Tarkoitus on kuormittaa ja kehitt\u00e4\u00e4 niit\u00e4 lihaksia, joita lajisuorituksessa tarvitaan. Lajispesifisest\u00e4 voimaharjoittelusta pes\u00e4pallossa on tarjolla rajoitetusti tieteellist\u00e4 n\u00e4ytt\u00f6\u00e4, mink\u00e4 takia olisi t\u00e4rke\u00e4\u00e4 tutkia asiaa tarkemmin. Tutkimuksen tarkoitus oli vertailla kahden harjoitusprotokollan tehokkuutta ly\u00f6ntisuorituksen kehitt\u00e4miseen. Harjoitusprotokollasta riippuen ly\u00f6ntiharjoituksissa k\u00e4ytettiin joko painomailaa tai tavallista pes\u00e4pallomailaa. Tutkimukseen osallistui 20 nuorta pes\u00e4palloilijaa, joista kymmenen oli naisia ja kymmenen miehi\u00e4. Koehenkil\u00f6t suorittivat kolme lajiharjoitusta viikossa 7 viikon harjoitusjakson ajan. Tutkittavat jaettiin koeryhm\u00e4\u00e4n (n=10, ik\u00e4: 17.7 SD 0.45) ja kontrolliryhm\u00e4\u00e4n (n=10, ik\u00e4 17.7 SD 0.43). Koeryhm\u00e4 suoritti lajiharjoituksensa k\u00e4ytt\u00e4en oman normaalin pes\u00e4pallomailan lis\u00e4ksi ali-ja ylipainoisia mailoja, kun puolestaan kontrolliryhm\u00e4 suoritti lajiharjoitukset k\u00e4ytt\u00e4en pelk\u00e4st\u00e4\u00e4n omaa normaalia pes\u00e4pallomailaa. Lajiharjoitus sis\u00e4lsi 150 pes\u00e4pallon ly\u00f6ntitoistoa. Koeryhm\u00e4 suoritti ly\u00f6nneist\u00e4 \u2154 painomailoilla ja \u2153 tavallisella pes\u00e4pallomailalla. Painomaila ly\u00f6nneist\u00e4 puolet suoritettiin alipainoisella mailalla ja puolet ylipainoisella mailalla. Painomuunnellut mailat olivat painoltaan \u00b1 12 % tutkittavan oman pes\u00e4pallomailan painosta. Kontrolliryhm\u00e4 suoritti kaikki 150 ly\u00f6nti\u00e4 omalla pes\u00e4pallomailalla. Ennen ja j\u00e4lkeen harjoitusjaksoa tutkittavat suorittivat ly\u00f6ntimittaukset, joissa mitattiin ly\u00f6ntisuorituksen ajalta mailanp\u00e4\u00e4n liikenopeutta ja osuman j\u00e4lkeist\u00e4 pallon l\u00e4ht\u00f6nopeutta. Koeryhm\u00e4n mailojen liikenopeudet paranivat alipainoisella mailalla noin 7 % (p=0.062), normaalilla mailalla noin 10 % (p<0.01) ja ylipainoisella mailalla noin 11 % (p<0.05), kun puolestaan kontrolliryhm\u00e4n mailojen liikenopeudet pysyiv\u00e4t l\u00e4hes muuttumattomina. Pallojen l\u00e4ht\u00f6nopeudet kasvoivat molemmilla ryhmill\u00e4 hieman, mutta tilastollisesti merkitsev\u00e4\u00e4 eroa ei kummankaan ryhm\u00e4n kehityksess\u00e4 ollut.\nLajispesifisen\u00e4 voimaharjoittelumuotona painomailoilla harjoittelu voi lis\u00e4t\u00e4 mailan liikenopeutta, mink\u00e4 my\u00f6t\u00e4 lajisuoritus voi parantua. Tulosten mukaan mailan kasvanut liikenopeus ei merkitse suoraan pallon l\u00e4ht\u00f6nopeuden kasvamista. Mailan liikenopeuden lis\u00e4ksi pallon l\u00e4ht\u00f6nopeuteen vaikuttaa oleellisesti osumatarkkuus.", "language": "fi", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Joose Kemppainen (joalkemp) on 2016-03-08 12:33:58.633662.
