Six elite cross-country skiers completed 30-meter sprints on two hills with slopes of 2% and 6%. Horizontal velocity and horizontal force were calculated using data from a laser distance meter. The strength of the linear relationship between force and velocity was tested using the repeated measures correlation method. We found a statistically significant linear relationship between force and velocity (p < 0,05). Velocity accounted for 50% (r2 = 0,497) of the variance of force on the hill with 2% slope and 56% (r2 = 0,558) of the variance of force on the hill with 6% slope. Our results show a lower percentage of variance explained compared to other studies that have investigated the F-v-P relationship in sprinting in track and field athletics. Based on our results, we can conclude that the validity of our results is questionable when using the novel method to test the F-v-P relationship in cross-country skiing. The presented protocol, which is time and energy efficient, is a potentially useful tool to better understand the mechanical properties of the upper body muscles of cross-country skiers. However, for the protocol to provide valid and reliable results, future studies should focus on optimizing the measurement procedure and data analyses"},{"@xml:lang":"sl","#text":"Namen študije je bil preveriti veljavnost izračuna izhodnih spremenljivk meritev odnosa sila-hitrost-moč (F-v-P) pri simulaciji teka na smučeh z rolkami. Merjenci so izvedli 30-metrski sprint s klasično tehniko na strminah z naklonoma 2 % in 6 %. Horizontalna hitrost sprinta in horizontalna sila sta bili izračunani iz podatkov, zajetih z laserskim merilnikom. Moč linearne povezanosti med silo in hitrostjo je bila izračunana s pomočjo korelacije za ponovljene meritve. Ugotovili smo, da je linearna povezanost med silo in hitrostjo statistično značilna (p < 0,05). S spremenljivko hitrosti nam je uspelo pojasniti 50 % (r2 = 0,497) variance sile pri strmini z naklonom 2 % ter 56 % (r2 = 0,558) variance sile pri strmini z naklonom 6 %. Rezultati testiranja odnosa F-v-P v primerjavi z drugimi študijami, ki izhajajo iz atletike, kažejo manjši delež pojasnjene variance. Na podlagi rezultatov torej zaključujemo, da je verodostojnost rezultatov, pridobljenih z novouporabljeno metodo, nezanesljiva. Enostavno izvedljiv, časovno nepotraten in posledično minimalno utrujajoč protokol merjenja bi lahko v prihodnje bil orodje za podrobnejši vpogled v mehanske lastnosti mišic rok pri tekačih na smučeh – vendar so za povečanje verodostojnosti in zanesljivosti rezultatov potrebne dodatne raziskave, usmerjene v optimizacijo merilnega postopka in metod obdelave signalov"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-9SDM3NO4","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-9SDM3NO4"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-9SDM3NO4/325bc2d5-3914-4a29-9fd8-b6495f67cd4a/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za šport"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-9SDM3NO4/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-9SDM3NO4"}}}}
