山地户外运动鞋对人体下肢落地冲击的影响研究

Effect of Mountain Outdoor Sports Shoes on Landing Impact of Human Body Lower Limbs

为探讨山地户外运动鞋对人体下肢落地冲击的影响,以光学三维动态捕捉系统与Kistler三维测力台实时采集并对比被试者穿着高缓震户外运动鞋与无缓震户外运动鞋完成山地户外运动常见落地动作时下肢的地面反作用力数据与下肢关节运动学参数。结果发现,穿着高缓震户外运动鞋与无缓震户外运动鞋落地时,人体下肢地面反作用力存在显著性差异:穿着高缓震户外运动鞋时下肢落地的地面反作用更小,对下肢的冲击与损伤更小;穿着高缓震户外运动鞋与无缓震户外运动鞋落地时人体下肢关节的活动度、触地角度、最小角度、最大角速度、出现时间均不存在显著性差异,但穿着无缓震户外运动鞋时下肢关节的活动度小于高缓震户外运动鞋,表明穿着无缓震户外运动鞋落地时下肢的损伤风险更大。

To explore the impact of mountain outdoor sports shoes on the landing impact of human lower limbs,an optical 3D dynamic capture system and a Kistler 3D force measurement platform were used to collect and compare the ground reaction force data and lower limb joint kinematic parameters of participants wearing high buffered outdoor sports shoes and non buffered outdoor sports shoes when completing common landing movements in mountain outdoor sports The results show that there is a significant difference in the ground reaction force of the lower limbs when wear-ing high buffered outdoor sports shoes and non buffered outdoor sports shoes on the ground.However,when wearing high buffered outdoor sports shoes,the ground reaction force of the lower limbs on the ground was smaller,and the impact and damage to the lower limbs were smaller There is no significant difference in the joint activity,contact an-gle,minimum angle,maximum angular velocity,and appearance time of the lower limb joints when wearing high buff-ered outdoor sports shoes and non buffered outdoor sports shoes on the ground However,the joint activity of the lower limb joints is lower when wearing non buffered outdoor sports shoes than that of wearing high buffered outdoor sports shoes,indicating that the risk of lower limb injury is greater when wearing non buffered outdoor sports shoes Key outdoor sports shoes;high buffering;no cushioning;lower limb joint injury;ground reaction force.
