Lis\u00e4ksi tutkitaan, eroaako maksimivoimantuoton taso, lihaksen poikkipinta-ala ja rasvaton massa sek\u00e4 niiden yhteydet suomalaisten eliittitason voimaurheilijoiden ja fitnessurheilijoiden v\u00e4lill\u00e4. \n\nTutkimukseen osallistui yhteens\u00e4 25 dopingtestattua urheilijaa, joista 13 kilpaili eliittitasolla fitnesslajeissa ja 12 voimalajeissa. Tutkittavat olivat 20-40-vuotiaita, ja heist\u00e4 noin puolet olivat naisia ja puolet miehi\u00e4. Tutkittavilta mitattiin ulomman reisilihaksen anatominen poikkipinta-ala ultra\u00e4\u00e4nell\u00e4, ja rasvattoman massan m\u00e4\u00e4r\u00e4\u00e4 arvioitiin ihopoimumittauksella, josta laskettiin my\u00f6s rasvattoman massan indeksi. Maksimivoimantuottoa mitattiin yhden jalan maksimaalisella isometrisell\u00e4 polvenojennuksella ja jalkapr\u00e4ssin yhden toiston maksimilla. Tutkimus toteutettiin osana Jyv\u00e4skyl\u00e4n yliopiston laajempaa poikkileikkaustutkimusta, ja jokainen koehenkil\u00f6 saapui liikuntalaboratoriolle mittauksiin yhden p\u00e4iv\u00e4n ajaksi. \n\nLihaksen anatominen poikkipinta-ala ja rasvaton massa olivat tilastollisesti eritt\u00e4in merkitsev\u00e4sti (p < 0,001) yhteydess\u00e4 maksimivoimantuoton suuruuteen sek\u00e4 voimaurheilijoilla ett\u00e4 fitnessurheilijoilla. Suurin korrelaatio havaittiin voimaurheilijoiden rasvattoman massan ja jalkapr\u00e4ssin yhden toiston maksimin v\u00e4lill\u00e4 (r = 0,966). Lihaksen poikkipinta-alassa, rasvattomassa massassa, rasvattoman massan indeksiss\u00e4 ja voimamuuttujissa puolestaan ei havaittu tilastollisesti merkitsevi\u00e4 eroja voima- ja fitnessurheilijoiden v\u00e4lill\u00e4. \n\nT\u00e4m\u00e4n ja aiempien tutkimusten perusteella lihaksen poikkipinta-ala ja rasvattoman massan m\u00e4\u00e4r\u00e4 voivat selitt\u00e4\u00e4 maksimivoimantuotossa havaittuja eroja saman tasoisten urheilijoiden v\u00e4lill\u00e4 jopa 65\u201390 %, mik\u00e4 on t\u00e4rke\u00e4\u00e4 ottaa huomioon k\u00e4yt\u00e4nn\u00f6n harjoittelussa.

Voimamuuttujien osalta ryhmien v\u00e4liset tulokset olivat ristiriitaisia aiempaan tutkimustietoon verrattuna, kun lajien v\u00e4lill\u00e4 ei havaittu tilastollisesti merkitsevi\u00e4 eroja.
