内容記述 |
Two highly skilled and two intermidiate skiers served as subjects. They used same skis which attached reference marks on each ski in order to analyze ski's movement such as angle of attack and edging angle. Movement of skier's body and skis during paralell turns were filmed by two 16 mm high speed movie cameras (100fps) from tow different directions. Analyzing these films, three dimensional movement of skier's body and skis during parallel turns were obtained by using DLT method. From this study, results were summarized as follows: (1) Upward movement in initiation not only reverse the turn easily but also place the C.C. forward easily at the first half of the next turn. (2) It could be perform the narrow path turn (the turn with less skid and smaller angle of attack) to place the C.G. forward in the first half of the turn. (3) In bending turn, the C.G. moved backward even in the first half of the turn according to circumstances. It is important to mention that backward movement of the C.G. leads backward leaning posture which brought about difficulty to controll skis at the second half of the turn when we perform the bending turn. (4) It could be said that the magnitude of edging angle, angle of attack and lateral movement of C.G. were almost the same in performing different style of turn, if the magnitude of radius and speed of these turns were perfomed as same. |
