abstract

Progressivity of Basic Elements of the Slovenian National Alpine Ski School Ski school programmes in different countries are adapted to the local conditions and skiing trends. The aim of the study was to establish the progressivity of the three basic elements of the Slovenian ski school in terms of the duration of individual turns and their phases. Eight participants were recorded as they performed three basic elements of the Slovenian national ski school: wedge curves – E1, turns with a wedge push-off – E2 and basic swinging – E3. According to the ski school, the elements were divided into phases. The results of the computer-aided video analysis showed that in the beginning types of skiing in the same conditions on the same length of terrain, the average durations of turns and the times of comparable initiation and steering phases of the elements shortened on the methodical upward scale (from E1 to E3). The number of turns executed on the same length of terrain from E1 to E3 increased. A larger step in motor task complexity was indicated when a pole plant was included in skiing elements. Further, relatively large differences were observed in time durations among subjects executing the same elements. In conclusion, it can be assessed that the basic elements of the ski school are placed gradually in terms of progressivity in time durations. Progresivita základních elementů slovinské národní školy alpského lyžování Programy lyžařských škol v různých zemích jsou přizpůsobeny místním podmínkám a lyžařským trendům. Cílem této studie bylo stanovit progresivitu tří základních prvků slovinské lyžařské školy, pokud jde o dobu trvání jednotlivých zatočení a jejich fází. U osmi účastníků bylo zaznamenáno, jak provádějí tři základní prvky ze slovinské národní lyžařské školy: E1 – oblouk z pluhu; E2 – oblouk z přívratu vyšší lyží E3 – paralelní oblouk. Podle lyžařské školy byly prvky rozděleny do fází. Výsledky počítačové video- analýzy ukázaly, že na začátku lyžování za stejných podmínek a stejné délky terénu, je průměrná doba zatáčení a časů srovnatelného zahájení a řízení fází, jsou tyto prvky dle metodické vzestupné škály zkráceny (od E1 po E3). Počet zatočení provedených na stejné délce terénu se zvýšil; od E1 po E3. Delší pokrok byl v motorické komplexnosti úlohy, indikován při jejich začleněného do lyžařských prvků. Poměrně velké rozdíly mezi subjekty, které prováděli stejné prvky, byly zaznamenány v době jejich trvání. Na závěr lze usuzovat, že základní prvky lyžařské školy jsou postupně z hlediska progresivity podle času jejich trvání, implementovány.
