Syd\u00e4men autonomisen s\u00e4\u00e4telyn muutokset kest\u00e4vyysurheilijoilla. Liikuntafysiologian Pro gradu-tutkielma. Liikuntabiologian laitos. Jyv\u00e4skyl\u00e4n yliopisto. T\u00e4m\u00e4n tutkimuksen tarkoituksena oli tarkastella harjoittelu- ja kilpailukaudella tapahtuvia muutoksia autonomisen hermoston toiminnassa kest\u00e4vyysurheilijoilla sykevaihtelumenetelmien avulla. Viisitoista kansallisen tason hiiht\u00e4j\u00e4\u00e4 (8 miest\u00e4, ik\u00e4 21\u00b14 v; 7 naista, 17\u00b11 v) osallistui tutkimukseen, jossa seurattiin sykevaihtelussa ja kest\u00e4vyyssuorituskyvyss\u00e4 tapahtuvia muutoksia peruskuntokaudelta kilpailukaudelle (syyskuu-tammikuu). Sykevaihteluanalyysit tehtiin passiivisesta kallistuskokeesta, 24hsykenauhoituksesta ja portaittain nousevasta kuormituksesta, jotka suoritettiin kuukauden v\u00e4lein viisi kertaa seurannan aikana. Kest\u00e4vyyssuorituskyky\u00e4 mitattiin suoralla maksimaalisen hapenottokyvyn testill\u00e4 kolme kertaa seurannan aikana (syyskuumarraskuu- tammikuu). Maksimaalinen hapenkulutus pieneni koeryhm\u00e4ll\u00e4 (62.S\u00b17.9 => 61.9\u00b16.S => 59.7\u00b15.9 ml\u00b7kg-1\u00b7min-1 p<.05). Uupuminen testiss\u00e4 tapahtui marraskuussa my\u00f6hemmin (p<.05) kuin syyskuussa, mutta tammikuussa suoritus oli palautunut l\u00e4ht\u00f6tasolleen (26\u00b14 => 27\u00b15 => 26\u00b14 min). Sykevaihtelumuuttujissa ei havaittu ryhm\u00e4tasolla muutoksia. Yksil\u00f6tasolla tapahtuneet muutokset osoittivat, ett\u00e4 sykevaihtelun lis\u00e4\u00e4ntyminen kuormituksen ja passiivisen kallistuksen aikana oli yhteydess\u00e4 kest\u00e4vyys suorituskyvyn paranemiseen. Sit\u00e4 vastoin sykevaihtelun v\u00e4heneminen 24h mittauksessa liittyi kest\u00e4vyyssuorituskyvyn paranemiseen. Sykevaihtelun ja kest\u00e4vyyssuorituskyvyn muutosten v\u00e4linen yhteys viittaa siihen, ett\u00e4 parasympaattisen aktiivisuuden kasvaminen liittyy hyv\u00e4n harjoitteluvasteen syntymiseen ja suorituskyvyn paranemiseen kest\u00e4vyysharjoittelussa. Sykevaihtelu voi v\u00e4henty\u00e4 24h-mittauksessa parasympaattisen aktiivisuuden kasvaessa kest\u00e4vyysurheilijoilla, joilla on ennest\u00e4\u00e4n suuri parasympaattinen aktiivisuus ja sykevaihtelu. T\u00e4ten passiivisen kallistuksen ja erityisesti kuormituksen aikaisen sykevaihtelun mittaaminen soveltuu sykevaihtelumenetelmist\u00e4 paremmin kest\u00e4vyysharjoittelun seurantaan.", "language": "fi", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2008-01-08T08:18:04Z (GMT).
