不同鞋底硬度对跑步时下肢生物力学特征的影响

运动鞋鞋底硬度会影响缓冲性能和保护作用,进而影响穿着者的运动表现。通过分析9名跑者分别穿着7种不同鞋底硬度运动鞋跑步时下肢运动学和动力学指标的变化,探析鞋底硬度对鞋缓冲性能和防损伤性能的影响,为运动鞋的设计与制作提供理论依据。结果表明:随着鞋底硬度的增加,跑步着地时足外翻和外旋的程度增大,进而增加损伤几率。足着地时的垂直地面反作用力第一峰值力不受鞋底硬度的影响。30°和40°是较理想的鞋底硬度,缓冲效果较好,同时可以降低足部过度运动的风险。

Effect of different sole hardness on the biomechanics of lower limb in running

The sole hardness of sports shoes will affect the cushioning properties and protective effects, and then affect the performance of the wearers. By analyzing the changes of kinematics and dynamics of the lower limbs of 9 runners in seven different sole hardness, the research is to discuss the effect of different hardness soles of sports shoes on cushioning and anti-injury performance, and to provide a theoretical basis for the design and production of sports shoes. Conclusion: With the increase of hardness, there is a tendency to increase the degree of foot eversion and extorsion while running, and may increase the risk of injuries. The first peak force of the vertical ground reaction force is not affected by the hardness of the sole. 30 degrees and 40 degrees is an ideal hardness of soles, the cushioning of the sole is better. At the same time, it can reduce the risk of excessive movement of the foot.
