摘 要:通过对clap式冰刀与传统冰刀蹬冰机制的比较得出,clap式冰刀蹬冰技术原理体现在两个方面:一是通过提高踝关节的灵活性来改变下肢各关节的发力性质;二是通过冰刀结构的改变来揭示速滑蹬冰技术动作加速理论的适用条件。其核心是提高踝关节的灵活性。By comparing the skating mechanism of clap style skate blades and traditional skate blades, the author revealed the following findings: The technical principle of skating with clap style skate blades showed in such two aspects: 1 )force breaking out performance of lower limb joints was changed by eabancing the flexibility of ankle joints; 2)the applicable conditions of the theory of acceleration of skating tectmical movements used in speed skating were revealed through the change of structure of skating blades. The key point is to enbancc the flexibility of ankle joints.
