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. Verf.-Referat
