The purpose of this study was to analyse the motion of snowborading novice turn and??carving turn. The subjects of this study were selected from active members of snowbording club of the S??University and they were all male students and the researchers divided them into two groups of skilled (certified??members of KSIA) and unskilled category(less than 2 years experience). Slope degree was 9° and the??subjects made one turn in a rectangular area (6m×6m×2m) and a total of 4 video cameras were set up??(30frames/sec, 1/500sec) in between analysis area. Subjects weared leotard type apparel and discernable tapes were??attached in joint areas of the body. The higher degree of change in terms of center of mass height were detected??from unskilled group than skilled in novice and carving turn analysis and the difference were more significant in??carving turn's case. The maximum speed in the center of mass for novice turn of the skilled was found in??intermediate time zone while it was in the second half of carving turn for the skilled subjects. Meanwhile, unskilled??subjects' maximum speed was detected in early portion of both novice and carving turn. In case of view analysis??of the foreground angle of trunk and the angle between upper body and left thigh, the unskilled group showed a??higher degree of change. It was found that carving turn had more changes in aforementioned angle??measurements. In the analysis of steering angle unskilled group showed a discernable changes than the skilled group.??It was also found that carving turn showed a lesser degree of angle change than novice turn. Finally, the size??of area of triangle formed by the vertical lines formulated by center of mass, deck and ground was bigger??in case of unskilled group than skilled. It was also detected the area in the carving turn was smaller than??the novice turn.
