Tutkittavana oli kaksi Jyv\u00e4skyl\u00e4n Kentt\u00e4urheilijoiden harjoitusryhm\u00e4\u00e4, joista toinen toteutti erilaisia hyppyj\u00e4 sis\u00e4lt\u00e4v\u00e4n radan aina harjoitusten alussa (N=7) ja toinen toimi kontrolliryhm\u00e4n\u00e4 jatkaen normaalia harjoittelua (N=7). Lapset suorittivat nopeustestin (lent\u00e4v\u00e4 20 m) ja hyppytestit (kevennyshyppy ja kyykkyhyppy) ennen harjoitusjaksoa ja sen j\u00e4lkeen. \n\nKummankaan ryhm\u00e4n kohdalla ei tapahtunut merkitsevi\u00e4 muutoksia nopeustestituloksissa, mutta nopeustestitulokset olivat positiivisesti suuntaa antavia hyppelyharjoittelun eduksi. Hyppelyharjoitteluryhm\u00e4n kevennyshyppytulos heikentyi tilastollisesti merkitsev\u00e4sti, mutta sen taustalla on mit\u00e4 todenn\u00e4k\u00f6isemmin vaikuttanut lasten heikko kyky suorittaa hyppytestej\u00e4.
