摘要
运用生物力学方法,对国内优秀速滑运动员新旧冰刀起跑技术进行比较分析,得出以下结论:(1)目前我国运动员采用新式冰刀站立式起跑重心投射到前支撑点的距离偏大;(2)起动瞬间,采用新式冰刀的前倾角度、后蹬角度普遍偏大,导致运动员水平瞬时速度下降;(3)疾跑阶段,运动员是用高频率滑跑来快速完成疾跑阶段而转入滑行阶段的。
Adopting biomechanical methods,the authors compared the top Chinese skaters starting techniques by use of old and new runners. It was concluded that the length of standing startoff of the new runners when gravity was reflected on the front supporting point was too long. The angles of leaning forward and stroking backward were too big at the instant of startoff,which led to the slow down of the instant speed. And last,the athletes were using highpitched skating to finish speedy phase and begin skating phase.
