鞋钉的长度、数量、形状及分布的研究

Research on Length, Number, Shape and Distribution of Sports Shoe Nails

通过对鞋钉在不同场地下拔出力的实验，结合文献，采用比较分析的方法，从鞋钉的长度、数量、形状及分布的角度分析，提出在塑胶跑道上鞋钉要短而尖．在煤渣跑道上底座直径要大．并可适当地加长，最后提出前脚掌鞋钉采用切面锥形钉．且鞋钉的分布应多位于跖骨和大脚趾上．这对于科学地设计钉鞋，提高运动的成绩有很大的参考价值．

Through experiment on pulling power of shoe nails on different ground, on the basis of References, foom the angle of comparative analysis, the length, number, shape and distrbution of shoe nails are analysed. It is proposed that nails used on the plastic cement race tracks should be short and sharp, that those used on the cinder race tracks be big on their bottom diameter and properly prologed, and then that those of the front half of shoes can sectioned coneshaped nails and their distribution should be more than under the big toen and metalarsal bone, Authis is of great value for References to scientifically design the shoe nails so as to raise playdrs'athletic results.
