冰刀鞋刀桥结构差异对下肢表面肌电的影响

Influence of Structural Difference in Ice Skate Shoes Bridge on Energy Regression of Lower Limbs

速滑冰刀鞋的刀桥结构不同,其对运动员下肢的能量消耗也就不同。通过将不同刀桥结构的传统克莱普冰刀鞋和改进后的克莱普冰刀鞋进行能量测试,发现改进刀桥结构的克莱普冰刀鞋对股直肌、胫骨前肌、股二头肌、腓肠肌的表面肌电做功与传统刀桥结构的冰刀鞋具有显著性差异,前者能够降低运动员的整体下肢能量损失。

The knife bridge structure of speed skating skates is quite different,and its energy consumption on Athletes'lower limbs is also different.Through the energy test between the traditional clap skates with different knife bridge structures and the new clap skates,it is found that the surface EMG work of the new clap skates with the new knife bridge structure on the rectus femoris,anterior tibial muscle,long peroneal muscle and posterior tibial muscle is significantly different from that of the traditional skates.The new clap skates can save the athletes'energy loss of lower limbs.
