内容記述 |
Takeoff and landing motions of triple Lutz jumps in 9 top-class Japanese figure skaters were videotaped at 250 fps and time analysis were carried out by reproducing the video tape. Field numbers of the recorded video tape according to the instance of the toe making contact with the ice, taking off and landing were identified. From these time data and observations of the orientations of skaters' shoulder by eye-measurement, flight (airborne) time, revolutions of the skaters' body before takeoff, during airborne and after landing were estimated. Although in approach of Lutz jump skater should use back-out edge according to the official rule, some skaters used back-in edge in the approach run. The number of rotations of the body in airborne phase in triple Lutz jump were ranged from 2+1/8 to 2+1/2 rev and the remaining part of 3 rotations were performed in the approach phase and after landing. Skaters were categorized into 3 types with the magnitude of the number of rotation of the body in approach and after landing; 1) more rotation before takeoff, 2) more after landing and 3) less rotation both before takeoff and after landing. Although the rotation angle measured with the landing edge should be within 90 deg in the official rule, the rotation angle of the shoulder reached over 90 deg in all the skaters of the present study. Large differences in the rotation angle of the shoulder were observed between the subjects and this result might suggest a necessity of a new rule on the rotation angle before takeoff in all kinds of jumps in figure skating. |
