| 摘 要： | 运用影像测量的方法,以2009年黑龙江省短道速滑锦标赛区县组（13岁以下）女子运动员技术滑比赛入弯道技术为研究对象,对比赛现场进行三维DLT拍摄,对入弯道右腿蹬冰技术进行运动学分析。结果表明：1.入弯道时机的把握和控制是合理使用入弯道技术和保持较高速度的关键因素;2.七台河市运动员入弯道右腿蹬冰能力明显好于哈、齐、牡、佳等地市运动员;3.七台河市运动员膝角的初值与均值明显小于其它地市运动员相应值,是七台河市运动员入弯道右腿单支撑蹬冰阶段身体姿势低的主要原因。

| Abstract: | Taking female athletes(under 13 years old) from county-group as research subject who participating Short track speed championship happened in Heilongjian in 2009 and using the method of image measurement,the author shoots the competition scene in 3D DLT style and operates a Kinematic analysis on the foot’s push-off technique on curve-beginning.The result shows that: 1.the key to use curve-beginning technique and keep a high velocity is to grasp and control the time of curve entering;2.the capacity of using right foot’s push-off tenique of Qi-taihe city is better than Ha Erbin,Qi Qiha’er,Mu-danjiang and Jia-musi’s;3.the knee angle’s initial value and average value is apparently smaller than relative values of the other districts and it’s the main reason that athletes in Qi-taihe city keep a low posture when they do the right foot’s push-off technique on curve-beginning. |
