花样滑冰内结环跳跃动作的运动学研究

Biomechanical Analysis on Sal chow Jumping Movements of Figure Skating

采用艾立尔系统和三维DLT方法,对中国杯大奖赛上我国运动员及世界优秀选手的内结环跳跃动作进行定点三维测试,比较分析他们在完成同样跳跃动作时的人体重心垂直方向位移-时间与速度-时间等的相关参数,并对我国运动员提出增加起跳的水平速度的建议,为预测和展望新难度动作提供参考。

Using the methods of Alier system and three-dimensional DLT, experts group conducted three-dimensional track point test on movement of sal chow jump of our athletes and other top athletes in world at China International Figure Skating of the ISU. They compared the Chinese top athletes with foreign top athletes in the parameters of distance-time and velocity-time in vertical direction of body center of gravity, put forward that the height of velocity in take off of jump should be increased, and offered references for forecasting and prospecting new difficulty movements.
