Human locomotion is an integrated phenomenon of motions occurring simultaneously in three planes in space. For the purpose of analysis of the mechanics of locomotion, it is necessary to record the movement in three planes respectively. In this study, pass ways of knee and ankle joints of left leg were recorded during walking and running on a motordriven treadmill. Three subjects fastened miniature bulbs on the knee and ankle joint of the left leg. Loci of miniature bulbs were photographed on 35 mm film over five cycles. The results were as follows; 1) Relation between the pass curve and the speed. Ankle joint; The pass curve of ankle joint formed a long ellipse during walking and running. In horizontal plane, the displacement of ankle joint is getting larger according to the increase of walking and running speed. In vertical plane, the ankle joint is more elevated during running at higher speed, though it is not changed during walking at higher speed. Knee joint; The pass curve of the knee joint makes an unsymmetrical figure eight during walking, while, during running, that forms a shape of the pendulum. In horizontal plane, the larger the displacement of knee joint was, the higher became the speed of walking and running In vertical plane, the knee joint is raised more during running at higher speed, though during walking at higher speed that is not changed. 2) Relation between the pass curve and the inclination. The inclination of the ground does scarcely effect on the pass curves of ankle and knee joints over range of the grade from 0° to 10° in walking and from 0° to 6° in running.
