SITUATIONAL BIOMECHANICAL PARAMETERS AT SLALOM CARVING SKIS IN TOP LEVEL SKIERS

Abstract

Skiing is a sport performed under exceptional competition conditions, especially taking into consideration environment, skiing trail with its special characteristics. It is impossible to carry out an investigation of the alpine skiing technique in laboratory conditions. Because of that it is only possible to carry it out during a competition. In this paper we selected special parts of the trail based on the predetermined goal to determine the carving slalom skis efficiency. Besides this we determined certain markers of the slalom technique that represent biomechanical situational kinematical space parameters: length with five and angle with six variables. Besides the investigation results, after the statistical processing, we found that the certain kinematical situational variables of slalom technique at carving skis have different mutual relations.
