| 摘 要： | 抛跳技术是花样滑冰双人滑技术动作中最复杂、最难掌握的一项技术动作,它也是代表花样滑冰双人滑技术水平的重要标志,因此对花样滑冰双人滑抛跳技术的探讨和研究具有重要的现实意义。运用运动生物力学、运动学解析、数理统计、文献资料等方法,对花样滑冰双人滑抛跳动作进行技术指标测试和研究。结果表明：空停时间和空中水平位移在完成动作过程中起关键作用,水平速度和腾空高度对完成高难度抛跳动作有直接影响。腾空时间应在0.9s以上,空中水平位移应在8.8m以上,以保证在空中完成转体动作,水平速度应在4.5m/s以上,水平速度是提高旋转冲力和角速度的重要保证,只有努力提高水平速度才能获得足够的旋转冲力,完成优质量、高难度、多周数的跳跃动作。

| Abstract: | The throw jump skill of pairs figure skating is the most complex and difficult motion and also is an important indicator of pairs figure skating skill level. Therefore,it＇s significant to discuss the skill. With the methods of sports biomechanics,kinematics analysis,mathematical statistics and documentary information,the article has a research on the pairs＇throw jump skill of figure skating. The results show that the flying time and flying horizontal displacement play a key role for performing the motion; the horizontal speed and air height have a direct influence on performing a high difficult throw jump motion; in order to perform the spin motion,the flying time,flying horizontal displacement and the horizontal speed should respectively be above 0. 9s,8. 8m and 4. 5m/s. Because the horizontal speed is the important ensurence of improving the rotational momentum and angular velocity,only if the horizontal speed is heightened,the skater can perform a topquality,high difficult,multiloop jump motion with enough rotational momentum. |
