Outstanding Speed Skating Athletes Curve Push Technology Kinematics

This text uses the method that the image measures obtain and reflect the kinematics parameter that elites curved a technology. Through curved kinematics of push-off technology analyses under the terms to world outstanding cross-country sportsman match, Finding out the main factor, which influences the curved push-off technology. Establish the correct curved push-off technological concept, Define that the speed skating pedals theintension which ices the movement theory, set up the elite's system oftechnical parameter of curved way, For appraise engineering level and instruct modern to train practice to offer the theoretical foundation of sportsman synthetically.Draw following conclusions through analyzing: The speed changing value that sportsman's form supports stage is generally greater than one pair of stages of supporting, The two have more obvious differences; Reply the speed of step and change the range not big entirely, it is relatively small to fluctuate, the latter half one is general faster than the first a half, Demonstrate the characteristic accelerated gradually. Control the leg and demonstrate certain regularity with pedaling the proportion of time which ices stage, A step of replying of curved way is pedaled and ices time and smaller than the straight way for a piece of time to reply the step, Demonstrate the characteristic of high frequency. Pedal movements of icing and follow the great link and drive the little link, had to lower hip, the orders of having an effect of the knee, ankle joint; Supporting in the initial stage push-off and adopts the weight and pedals this kind of passive form of ice and pedals the ice only, The ones that are supporting on later stage and adopting by a large margin only are pedaling icing the speed that the way improves the centroid voluntarily, It is typical outburst type movements that this kind pedals technological movement of ice.
