【摘要】 本文运用影像测量的方法,以2008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单步的侧蹬冰滑行能力明显好于其它地市运动员,右腿快速蹬伸能力差异明显；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,造成七台河市运动员入弯道右腿单支撑蹬冰瞬间及右腿蹬冰过程中的身体姿势均低于其它地市运动员相应值。更多还原

【Abstract】 By methods of videotaping-measurement, with the curve-enter technique in technical skating match of the young female short track speed skaters who attended the Heilongjiang short track speed championships(U13) as objects of study. To shoot the match field with DLT, analyzed the right leg s push-off technique on curve-enter.The findings indicate:Firstly, the ability of controlling and seizing the opportunity is the key of keeping high velocity and applying the curve-enter technique rationally.Secondly, the skaters’ ability of Qitaihe of the right leg s push-off technique on curve-enter is better than the other city’s’, the discrepancy in ability of right knee extending is obvious. Thirdly, The Qitaihe athlete knee angle starting value and the average value are smaller than other prefecture athlete corresponding value are obviously create the Qitaihe athletes to enter the curve right leg list support pedal ice instantaneous and in the right leg pedal ice process bodily posture are lower than other prefecture athlete corresponding value the primary cause.更多还原
