Tutkimukseen osallistui 6 nuorta (10\u201413 v) rytmist\u00e4 voimistelijaa, joista \nkultakin analysoitiin kolme onnistuneinta suoritusta kummastakin tutkitusta piruetista. \nVideotallenteilta arvioitiin py\u00f6rittyjen kierrosten m\u00e4\u00e4r\u00e4, py\u00f6rimisakselin vertikaalisuus, sek\u00e4 \npiruetista saatavat pisteet, p\u00e4\u00e4asiassa lajin s\u00e4\u00e4nt\u00f6jen mukaisesti. Suoritusten vauhdinotoista \nmitattiin 3D-liikeanalyysin avulla, miss\u00e4 j\u00e4rjestyksess\u00e4 tukijalan nilkka-, polvi, ja \nlonkkakulmat ojentuivat, sek\u00e4 kuinka suuri et\u00e4isyys tukijaloilla oli toisiinsa vauhdinoton \nl\u00e4ht\u00f6asennossa, eli nelj\u00e4nness\u00e4 asennossa. Lis\u00e4ksi mitattiin tasapainokyky\u00e4 pass\u00e9- ja \nristivaakatasapainoasennoissa pysyttyn\u00e4 aikana (0\u201310 s), sek\u00e4 pohkeiden voimantuottokyky\u00e4 \nmaksimaalisella, isometrisell\u00e4 voimatestill\u00e4 jalkadynamometrilla.

Kun tilastollisessa tarkastelussa oli molemmat piruetit, \nkorrelaatioanalyysill\u00e4 havaittiin, ett\u00e4 piruetin vauhdinottoasennon leveys korreloi negatiivisesti \nkorkeampien pisteiden kanssa (r = -0,345; p < 0,05; n = 36).
