T\u00e4st\u00e4 syyst\u00e4 t\u00e4m\u00e4n tutkimuksen tarkoituksena oli vertailla vaihtelevan ja tasaisena pidetyn toistovaran vaikutuksia voimaharjoittelun adaptaatioihin kokeneilla harjoittelijoilla.\n31 tutkittavaa (27 \u00b1 4 vuotta), joilla tuli olla v\u00e4hint\u00e4\u00e4n kahden vuoden s\u00e4\u00e4nn\u00f6llinen voimaharjoittelutausta, satunnaistettiin RIR1-4 (n=16) ja RIR1 (n=15) ryhmiin. Molemmat ryhmist\u00e4 suorittivat 10 viikon voimaharjoitteluintervention. Ohjelma jaettiin kahteen viiden viikon mesosykliin, joiden sis\u00e4ll\u00e4 RIR1-4 -ryhm\u00e4n viikoittainen toistovaratavoite laski asteittain 4:st\u00e4 1:een. Sen sijaan, RIR1 -ryhm\u00e4 piti toistovaratavoitteen vakiona koko interventiojakson ajan. Ennen ja j\u00e4lkeen intervention suoritettiin yhden toiston maksimitestit (1 RM) kyykyss\u00e4 ja penkkipunnerruksessa ja vastus lateraliksen poikkipinta-alan ja triceps brachiin paksuuden mittaus ultra\u00e4\u00e4nell\u00e4.

Molempien ryhmien 1 RM kehittyi tilastollisesti merkitsev\u00e4sti (p < 0.05) sek\u00e4 penkkipunnerruksessa (RIR1-4 4 \u00b1 2 %; RIR1: 6 \u00b1 5 %) ett\u00e4 kyykyss\u00e4 (RIR1-4: 11 \u00b1 5 %; RIR1: 9 \u00b1 9 %).

Triceps brachiin paksuuden muutos oli merkitsev\u00e4 (RIR1-4: 6 \u00b1 6 %; RIR1: 2 \u00b1 5 %) vain RIR1-4 -ryhm\u00e4ll\u00e4 (p <0.01). Harjoituskohtaisen RPE:n keskiarvo oli lis\u00e4ksi alhaisempi (p <0.05) RIR1-4 -ryhm\u00e4ll\u00e4 (6.9 \u00b1 1) verrattuna RIR1 -ryhm\u00e4\u00e4n (7.7 \u00b1 1).\nTulokset eiv\u00e4t osoita, ett\u00e4 toistovaran vaihtelulla saavutettaisiin harjoitusvasteiden suhteen lis\u00e4hy\u00f6tyj\u00e4 verrattuna harjoitteluun tasaisesti l\u00e4hemp\u00e4n\u00e4 uupumusta.
