摘要
运用3D技术对速度滑冰中频幅组合与步速关系进行了探讨,首次提出了在周期性项目中区分定点支撑方式与动态支撑方式的概念。分析得出,由低速向高速滑行时,在步频与步速关系中,动态支撑方式遵循定点支撑方式的变化规律;但在步长与步速关系中,动态支撑方式却有与定点支撑方式相反的结果。
In this paper,3D technique is adopted to discuss the relationship between stride frequency and length combination and the stride rate in speed skating, and it is the first time to propose to differentiate the fixed-point strut way from the dynamic strut way concept in the periodic sports events. When from low-speed to high-speed,the dynamic strut way follows the change rule of the fixed-point strut way according to the relation between the frequency and the rate of stride ; But the result is opposite according to the relation between the length and the rate of stride.
