스노보드 부츠 개발을 위한 보행동작 특성분석

초록

The purpose of the study was to perform gait analysis of three different winter boots (BD, EZ, NS) and provide reference data for designing a multipurpose snowboard boots which can be used during snowboarding as well as for outdoors activities. Four male snowboarders who were from Korea Youth National Team and demonstrator participated in order to achieve the purpose of the study. Six 3D Motion analysis system (Vicon612 Motion Systems. Ltd., UK) and four force plates (AMTI ORG-6) were used to analyze the changes in kinematic and kinetic variables. Angular variables of lower limbs i.e. Peak max & min of knee and hip angles and Ground Reaction force (Fz) were calculated to measure the effect of three different winter boots on gait. The results obtained from the study are as follows: The type of vamp effected the limb moment. Soft boots (EZ) caused more hip adduction of supporting leg than stiff snowboard boots (BD) during one leg support phase and allowed bigger flexion of hip on swing leg. Wearing stiff snowboard boots (BD) caused larger hip’s internal and knee’s internal and external rotation of the supporting leg than normal winter shoes (NS). Boots type also effected the knee’s external rotation and flexion of the swing leg. Furthermore, it is considered that wearing stiff boots limited the ankle ROM due to which significant differences were also observed in knee flexion of the supporting leg.
