Ampuma-asennon vakauteen vaikuttaa massakeskipisteen korkeus ja tukipinta-ala. Kehon yksil\u00f6lliset mittasuhteet vaikuttavat varsinkin polviasennon statiikkaan. Aseen vakaanapito on onnistuneen laukauksen perusedellytys. Tasapaino on suorasti yhteydess\u00e4 tarkkuuteen asennon huojunnan kautta ja ep\u00e4suorasti aseen heilunnan kautta. My\u00f6s ampujan ja aseen v\u00e4liset voimat sek\u00e4 ampuma-asento vaikuttavat suoritukseen. T\u00e4m\u00e4n tutkimuksen tarkoituksena on kuvata n\u00e4iden tekij\u00f6iden vaikutuksia ammuntasuoritukseen ja niiden muutoksia ammunnan aikana. Tutkimuksessa 10 maajoukkueampujaa suoritti kilpailunomaisen ammuntasarjan (40 laukausta) pienoiskiv\u00e4\u00e4rill\u00e4 polviasennosta. 1\u20130 sekuntia ennen jokaista laukausta rekister\u00f6itiin aseen t\u00e4ht\u00e4yspisteen liikkeet, ampuja-asesysteemin painekeskipisteen liikkeiden keskihajonnat, per\u00e4- ja hihnavoimat sek\u00e4 tukik\u00e4den kyyn\u00e4rvarren kulma ja kyyn\u00e4rp\u00e4\u00e4n et\u00e4isyys polvesta.\r\nKeskim\u00e4\u00e4r\u00e4inen ammuttu osuma oli 10.03. T\u00e4ht\u00e4yspisteen vaakaliike (devX) oli 0.51 rengasv\u00e4li\u00e4 ja pystyliike (devY) 0.41 rengasv\u00e4li\u00e4 sek\u00e4 suhteelliset t\u00e4ht\u00e4ysajat maalitaulun keskustassa (Target%) 56 %, t\u00e4ht\u00e4yksen painopisteess\u00e4 (COG%) 86 % ja osumapisteess\u00e4 (Hit%) 61 %. Painekeskipisteen liikkeen keskihajonnat olivat sivuttaissuunnassa (sdX) 0.18 mm ja ampumalinjan suunnassa (sdY) 0.20 mm. Keskim\u00e4\u00e4r\u00e4inen per\u00e4voima oli 24 N ja hihnavoima 128 N. Kyyn\u00e4rvarren kulma oli 42.5 astetta ja kyyn\u00e4rp\u00e4\u00e4n et\u00e4isyys polvesta 8.9 cm. DevX (R = -0.480), Target% (R = 0.518) ja sdX (R = -0.422) olivat yhteydess\u00e4 osumatarkkuuteen (p \u2264 0.05).

Tukik\u00e4den kyyn\u00e4rkulma oli yhteydess\u00e4 hihnavoimaan (R = -0.643, p \u2264 0.05). Kyyn\u00e4rvarren kulma laski merkitsev\u00e4sti ammuntasarjan edetess\u00e4 (F = 3.632, p \u2264 0.001) ja per\u00e4voima laski merkitsev\u00e4sti, jos lepotaukoja ei huomioitu (F = 2.869, p \u2264 0.01). Lepotauon j\u00e4lkeist\u00e4 ja edellist\u00e4 laukausta verrattaessa osumatarkkuus, Hit%, per\u00e4voima ja kyyn\u00e4rvarren kulma kasvoivat merkitsev\u00e4sti tauon seurauksena (p \u2264 0.05).\r\nN\u00e4m\u00e4 tutkimustulokset vastaavat aiempia tutkimustuloksia, mutta selkeit\u00e4 erojakin oli ilmakiv\u00e4\u00e4ri- ja pienoiskiv\u00e4\u00e4riammunnan sek\u00e4 eri ampuma-asentojen v\u00e4lill\u00e4. T\u00e4ht\u00e4yspisteen ja painekeskipisteen liikkeiden yhteys ammuntasuoritukseen oli odotetunlainen, mutta hypoteesien vastaisesti n\u00e4m\u00e4 liikkeet eiv\u00e4t muuttuneet suorituksen aikana rasituksen tai lepotaukojen seurauksena. Ampuma-asennossa kuitenkin tapahtui muutoksia, joita saatiin korjattua taukojen aikana.
