Mieslentopalloilijoiden voimaominaisuuksien s\u00e4ilyminen valmistavan kauden ja kilpailukauden aikana. Liikuntabiologian laitos, Jyv\u00e4skyl\u00e4n yliopisto, 60 s. \n\nLentopallo on intervallityyppinen laji, jossa energiantuotto on alaktista. R\u00e4j\u00e4ht\u00e4v\u00e4ll\u00e4 voimal-la on lajissa keskeinen merkitys. Pelaajien vertikaalihyppykyvyst\u00e4 riippuva ulottuvuus ja ly\u00f6nnin voimakkuus ovat t\u00e4rkeimpi\u00e4 joukkueen menestyst\u00e4 selitt\u00e4vi\u00e4 fyysisi\u00e4 tekij\u00f6it\u00e4. N\u00e4it\u00e4 teho-ominaisuuksia pystyt\u00e4\u00e4n voimaharjoittelun avulla kehitt\u00e4m\u00e4\u00e4n. Kilpailu- eli ottelukau-della tulisi voimaominaisuudet pysty\u00e4 v\u00e4hint\u00e4\u00e4n s\u00e4ilytt\u00e4m\u00e4\u00e4n. Jos voimaharjoittelu lopete-taan kilpailukauden ajaksi, voimatasot laskevat ja suorituskyky my\u00f6s lajisuorituksissa heik-kenee. \n\nTutkimuksen tavoitteena oli selvitt\u00e4\u00e4 nelj\u00e4sti viikossa toteutetun voimaharjoittelun vaikutus lentopalloilijoiden voimaominaisuuksiin yhdeks\u00e4n viikon peruskuntokauden aikana. Lis\u00e4ksi tavoitteena oli selvitt\u00e4\u00e4, riitt\u00e4\u00e4k\u00f6 kaksi voimaharjoitusta viikossa yll\u00e4pit\u00e4m\u00e4\u00e4n voimaomi-naisuudet yhteens\u00e4 33 viikon valmistavan kauden ja kilpailukauden ajan, kun nopeusvoima- ja maksimivoimaharjoitusten m\u00e4\u00e4r\u00e4n suhde on ensin 1:1 ja my\u00f6hemmin 2:1. Koehenkil\u00f6in\u00e4 oli 11 SM-liigalentopalloilijamiest\u00e4, joiden ik\u00e4 oli 27,9 (\u00b1 2,9) vuotta, pituus 191,6 (\u00b1 5,7) cm ja paino 92,0 (\u00b1 10,3) kg. Tutkimuksessa mitattiin jalkakyykyn, rinnallevedon, penkki-punnerruksen ja ylivedon maksimivoimaa, vertikaalihyppyjen nousukorkeutta ja ulottuvuut-ta, heittopituutta 1 ja 3 kg palloilla sek\u00e4 toistom\u00e4\u00e4r\u00e4\u00e4 kestovoimakuntopiiriss\u00e4. Maksimi-voima kehittyi peruskuntokauden aikana 3-10 % (p < 0,05), hypyt ja heitot kehittyiv\u00e4t 4-7 % (p < 0,05) ja kestovoima 5 % (p < 0,05). Vertikaalihypyiss\u00e4 kehitystrendi jatkui viel\u00e4 val-mistavan kauden ja kilpailukauden syyskierroksen ajan. Kevennyshypyn nousukorkeuden keskiarvo parani yhteens\u00e4 4,0 (\u00b1 0,47) cm (p < 0,05), torjuntahypyn ulottuvuuden keskiarvo 6,4 (\u00b1 0,21) cm (p < 0,05) ja vauhdillisen ulottuvuushypyn keskiarvo 5,5 (\u00b1 0,23) cm (p < 0,05). Kilpailukauden aikana mik\u00e4\u00e4n mitattu voimaominaisuus ei laskenut, vaikka voima-harjoittelun m\u00e4\u00e4r\u00e4 v\u00e4heni puoleen peruskuntokaudesta. \n\nTulokset osoittavat, ett\u00e4 lentopalloilijan maksimivoiman ja nopeusvoiman s\u00e4ilymiselle kil-pailukaudella n\u00e4ytt\u00e4isi riitt\u00e4v\u00e4n kaksi voimaharjoitusta viikossa. Lis\u00e4ksi voimaominaisuuk-sien s\u00e4ilymisen kannalta riitt\u00e4\u00e4, ett\u00e4 maksimivoimaharjoitus tehd\u00e4\u00e4n yhdeks\u00e4n p\u00e4iv\u00e4n v\u00e4lein ja nopeusvoimaharjoitus viiden p\u00e4iv\u00e4n v\u00e4lein.\n\nAvainsanat: Lentopallo, kilpailukausi, voimaharjoittelu, maksimivoima, nopeusvoima", "language": "", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Kaappo Aittokallio (kaalaitt) on 2010-06-03 23:55:55.200751.
