摘要：This paper deals with the three dimensional comparative analyses of the carving front turn of alpine and boarder-cross snowboarders. The research aims to provide winter sports instructors and snowboarders with scientific and quantitative data for evaluation of carving front turn. To achieve the purpose, Alpine and Boarder-cross athlete from Korean National Team for 2018 Pyeongchang Winter Olympics were chosen as subjects. Body segment parameters and 90 coordinate points were selected and referred to calculate the CM and Position of CM in different segments. The turn was divided into 3 events and 2 phases. Three dimensional motion pattern analysis of each segment was performed and was analyzed with kinematical variables such as elapsed time, distance, velocity and angular variables. Comprehensive analysis was conducted and the result of the motion analysis indicated the major features in snowboard carving turn in two different sporting events. The proposed method and the results can be used as a reference for improvement of the training method and skills in snowboarding.
