Differences in the activation of selected muscles throughout a curve with the use of internal stabilizer in handicapped skiing group LW2
Abstract
Alpine disciplines of handicapped skiers do not only belong among competitive disciplines at the Paralympic Games, but also create certain form of leisure time physical activities of handicapped population. Whether skiing is an appropriate physical activity for individuals after unilateral above-knee amputation is often discussed, because of the high load placed on the healthy leg.
The aim of this research was to compare the activity of selected muscles throughout curves using an internal stabilizer for skiers LW2 groups, i.e. skiers with unilateral above-knee amputation. The research consisted of a comparison of two case studies and an analysis of specific physical activities - skiing with unilateral above-knee amputation.
It is a description based on surface electromyography and kinematic video analysis of the curves. The sample included two skiers (one male and one female) aged 22-30 years.
The results show variability throughout the curves on the inner and outer edge of the ski for both interindividual and intraindividual comparison of the presented types of curves.
