The purpose of this study was to analyze the kinematical variables in different phases of alpine snowboarders’ carving turn. Moreover, the study aims to improve the athletic performance and prevent injury through comparative analysis of different kinematical factors. To achieve the purpose of the study, four alpine snowboarders from Korean National Team for 2018 Pyeongchang Winter Olympics were chosen. For those time duration, distance, velocity and angular variables were calculated. The following conclusions were drawn: The overall elapsed time appeared to have greater significance in P1 than in P2. The displacement in the CM per event increased as a whole in medial-lateral displacement from E1 to E3. Forward-backward displacement results appeared similar in all of the subjects. Increasing trend in upward-downward displacement appeared in all the subjects. Furthermore, in E2 peak point in displacement could be observed which gradually decreased later. Velocity of CM in each event appeared to be the fastest in medial-lateral velocity and Forward-backward velocity in E2. Upward-downward velocity appeared the fastest in E3. The board’s velocity appeared the fastest in E1 however its velocity appeared the lowest in E2. Angle of ankle joint and angle of knee joint per event appeared the lowest in E2. Angle of hip joint and the angle of board- hip and shoulder’s twist appeared the lowest in E3.
