Abstract

In modern figure skating events, success of jumps with multiple rotations become more important factor to achieve a higher performance. The purpose of the present study is to investigate kinematic factors in successful jump with multiple rotations of the body. Kinematical data obtained from the 3-D motion capture of the jump performance were used for analysis. The subjects of this study were two Japanese women, three Japanese men and two foreign men skaters. Three types of jumps (Axel, Salchow and toe-loop) with different numbers of rotation of the body were analyzed. Main results from this study were summarized as follows; 1. Both the duration of flight and the height or the center of gravity of the skaters body in the jump with a large number of rotations were larger than in the jump with a small number of rotations. 2. The vertical component of initial velocity was larger in the jump with a large number of rotations while the magnitude of initial velocity did not depend on the number of rotations. 3. Longer duration of flight in the jump was most important to get higher success rate in each types of jumps. 4. As the duration of flight is determined by the initial vertical velocity at the takeoff of the jump, special training for takeoff technique which enable to get larger vertical initial velocity would be necessary for higher performance in the jump with multiple rotation.
