项目摘要

This project aimed at the clarification of the fundamental features, oigin and development of the mechanism of the human walking by means of experimental analysis using newly developed apparatuses. Thus far, the following fundamental facts were detected: The old theory, that the trajectory of the application point of body resultant force was laterally convex, was completely denied. Actually the trajectory was sraight until the phase in which the heel was raised and the metatarsal and toe parts were in contactwith the floor. In this phase the velocity of the moving application poimt became low. Then the trajectory was oriented to the big toe. Though at the beginning of the stance phase the heel was acted on by a high pressure, the resultant force did not support the whole body weight. The complete support occured at the phase in which the heel and the metatarsal heads part became in contact with the floor. On the other hand, the metatarsal heads part and the toes part fully support the body weight and exerted the accelerative force. The other phenomena concering with the development, sexial difference and origin are though fairly clearified, their analyses are still being analysed. These analyses will be finished in a few month.

本项目旨在利用新开发的仪器，通过实验分析，阐明人类行走机制的基本特征、起源和发展。至此，发现了以下几个基本事实：身体合力施加点轨迹为侧向凸的旧理论被彻底否定了。实际上轨迹是直的，直到脚后跟抬起跖骨和脚趾接触地面的阶段。在这个阶段，移动应用点的速度变低。然后弹道指向大脚趾。虽然在站立阶段开始时脚跟受到高压的作用，但合力并不能支撑整个身体的重量。完全支撑发生在足跟和跖骨头与地面接触的阶段。另一方面，跖头部和趾部充分支撑身体重量并施加加速度。与发展、性别差异和起源有关的其他现象虽然相当清楚，但对它们的分析仍在分析中。这些分析将在几个月内完成。
