Sažetak
To find an optimal balance position by using feet, ski shoes and skies on a snow surface, it is essential to harmonize the pressure that a skier produces during a turn as well as ground reaction forces (Falda-Buscaiot et al., 2017). In order to control the forces during the turn, skier needs to position the skies at a specific angle (edging angle), press them on the snow surface and rotate them (LeMaster & Supej, 2015). In everyday practice, it is quite common for a ski instructor to ask participants of a ski school to feel pressure under certain parts of the feet during skiing in order to improve their performance. At the same time literature is lacking concerning ground reaction forces and pressures achieved during recreational level skiing. The aim of the present study was to determine the differences between measured forces and their distribution under skiers’ feet during performance of different elements of ski technique. Analysis of kinetic parameters was conducted on four elements of alpine ski school (snowplough, basic turn, parallel turn, short turn). Variable sample included maximal force, medial force, lateral force and force on the heel of inner and outer leg in each turn. In each element of ski technique analysed were 12 turns (6 in left and 6 in right side). Kinetic parameters were measured by insoles designed for pressure detection (Novel, Pedar). Results of this study suggest that in-boot pressure over outer leg rises as the turns become more complex (from snowplough to short turn). When pressure is compared between inner and outer leg, significantly lower pressure level was on an inner leg (in ratio 1:4) in all elements of technique except during short turn. From a ski technique standpoint, it was clear that the pressure applied with the feet was higher towards more complex elements, and this finding is in accordance with advancements of plan and program of an alpine ski school. Therefore, it is necessary for ski instructors to teach skiing beginners where, when and how to apply pressure in each phase of learning process.
