Ankelvinkelns betydelse vid skateskidåkning: En pilotstudie
Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
Sweden has since the beginning of 1900 belonged to the world top among cross-country skiing and has 27 Olympic medals. Due to the latest literature, the development of the skatingtechnique has emanated from the angles that arise during skateskiing. Amongst that, the ankles dorsiflexion are important to get the largest force straight down into the ski. Even though it has been argued in official skatingtechniqueinstructions that skiers should have a large ankle ROM, there is no scientific literature to support that. The aim of this pilotstudy was to study the affect of the ankles ROM in skateskiing, five jump test and a diagonal jump test. Ten cross-country skiers (6 men and 4 women) from an athlete gymnasium participated in this study. The tests included were measurements of maximal dorsiflexion, five jump test and diagonal jump. Also, recording of ankle angle during skateskiing was accomplished. The skiers were ranked after the last two racing seasons. Significant correlation occurred between high ranking and large ankle angle at skiing gear 3 as well as between low ranking and large maximal ankle dorsiflexion, among the men. Among women no statistic correlation was found. The preliminary results of this pilot study shows that there may be a correlation between the ankle dorsiflexion and performance in skateskiing. Overall, this study support a future study including more exact measurements and a larger subject group.
