人体足底受力测试及其分析

Biomechanical Measurements and Analysis on the Sole of Human Foot

研究人体在不同条件下左右脚的受力和所受压力的平衡情况.采用Kistler测力鞋垫,选择部分军人和学生进行轻载和负重条件下的行军、跑步、跳跃等项目的测试;利用pedar-mobile分析系统,对采集的足底力学数据进行分析;对人体足底的受力向脚踝简化并进行分析计算.在行军、跑步时人体双脚的受力和所受压力基本平衡,而在跳跃时非常不平衡,但经过训练后可以得到明显改善.该研究对于科学培训空降兵、运动员的落地位姿及人体足部着地造成的损伤机理研究具有重要意义.

The balance of forces and pressures acting upon human foot is studied. Kistler insoles for the measurement of forces and pressures were used. Soldiers and students are choosen for the measurement. By the use of the pedar-mobile system, data about the human foot during walking,running and jumping were collected. Conditions of burdening some weight and not burdening any weight were included. Forces were composed and summed up at the center point of the ankle. As a whole the forces and pressures on the feet are balanced during walking and running. Yet it is not easy to attain a balance during jumping. But with trained people, they can be remarkably improved. The study can have important significance in the effective training of athletes and paratroopers and in studying the damnification mechanism and correlative pathology.
