内容記述 |
In figure skating, a successful jump with multiple rotations or the body is one of the most important factors to achieve a higher performance. In the present international figure skating events, excellent skaters perform jumps with more than three times of the body rotation. Recently, a Japanese junior skater has become to try Salchow jump with quadruple rotation of the body (Quad-Salchow jump). In this case study, motions of the skaters body during Quad-Salchow jump were kinematically analyzed and important factors in success or Quad-Salchow jump were investigated. Motions in Quad-Salchow jump of a junior skater in official practice in the all Japan junior figure skating championships held in 2002 were three dimensionally recorded by two synchronized high speed video cameras with 250 fps. Three dimensional coordinates of body landmarks were reconstructed by the direct linear transformation method (DLT). Some kinematic parameters which characterized the jump were calculated form three dimensional body coordinates of landmarks. Main results were summarized as follows; 1. No differences cuuld not be clarified for basic kinematic parameters on the jump such as approach velocity and initial conditions of the jump between successful and unsuccessful trials. 2. Actual numbers of rotation of body in the air were 2.94 in the successful jump and 2.91 in the unsuccessful jump even though in the jump with four times rotation of the body. This result indicated both successful and unsuccessful jumps were incomplete. 3. The flight time were 584 and 604 msec in successful and unsuccessful performance, respectively. Comparing with the results from the study on Triple-Lutz jump, these flight times were considered insufficient for four times of rotation or the body. 4. To accomplish a complete Quad-Salchow jump, a longer flight time should be needed enabled with higher initial vertical velocity of the body. From the results of the present study, it is recommended for the training or junior skaters to obtain enhanced jump ability in skating. |
