运用运动生物力学方法对世界优秀短距离速度滑冰运动员弯道“跑滑”技术进行了运动学个案分析,旨在探讨以日韩运动员为代表的短距离速度滑冰弯道“跑滑”技术动作的核心问题,对速度滑冰弯道滑跑过程中的腾空时相提出大胆的设想。研究认为:世界优秀短道速滑运动员弯道滑跑中存在下肢腾空的时相,具有明显的跑动迹象;双腿快速交替蹬冰,左右膝关节均未充分蹬伸,是产生跑动迹象和下肢腾空的主要因素;结合髋、膝关节角度变化的一致性分析表明,跑动迹象和下肢腾空时相主要是在左腿单支撑蹬冰结束到右腿单支撑蹬冰开始交替时刻,由左腿的不完全蹬伸配合右腿的髋、膝快速前摆着冰引起的。
The kinematic analysis of the world elite short-distance speed skaters curve “running slip ” technology using sports biomechanics method is to explore the short-distance speed skating curve “running slip ”The core issue of technical moves is to make a bold assumption about the time of flight during speed skating cornering. The study shows that there are obvious phases of running when the elite short track skaters bend in the cornering curve, and the legs are quickly and alternately pushed, and the left and right knee joints are not fully extended, which is a sign of running. And emptying the lower extremity; the consistent analysis of changes of hips and knees’ angles shows that the running signs and lower extremity phase mainly occur when the left leg single support pedaling ice end to the right leg single support pedaling ice start alternating time, Incomplete stretch left leg with the right leg hip, knees quickly caused ice before.
