신발유형별 보행동작의 운동역학적 동작분석 = Analysis on kinematics of walking locomotion in the case of shoes

다국어 초록 (Multilingual Abstract)

The purpose of this study was to prepare some useful data for the prevention of injury caused by shoes when female was walking. Kinematic variables were analyzed with the aid of the visual materials filmed with a 16mm high speed camera, such as angular changes of joints, displacement, velocity, and momentum of the center of body gravity. The subjects for the research were normal 4 female high school students: The analytic results of the mechanism of each locomotion pattern were as follows:
1. It is desirable Kinematically that the dispersion of power should not be caused in the movement of lower-legs by keeping natural flexion and extension of joint.
2. Too much vertical displacement of the center of body gravity was thought undesirable because it caused the dispersion of power against the moving direction. To get some propulsion in the moving direction, it was efficient to use as much energy as possible from 8 F-F support phase to the toe-off. And also the center of body gravity was moved by the inertia just after toe-off.
3. The correct walking motion occurred when the walker moved their hip joint or knee joint gently with their upper body upright and their eyes looking around.
4. In order to lengthen the stride it was essential to practice intensively the flexion of the hip joint, extension of knee and plantar flexion of ankle joint.
5. It was proved that in race walking, they could get much greater propulsion from the flexion of the ankle joint than from the hip joint or the knee joint. It was, therefore, very important to train walkers so that the initial planter flexion of the ankle joint might occur from 6 F-F of the supporting phase.
6. The flexion of the ankle joint produced the added propulsion in the moving direction but the excessive flexion increased energy consumption and caused strain on the ankle joint because it dispersed power in moving the center of body gravity.
7. It was desirable to narrow the ankle of the flexion of the hip and knee joints because it could speed up revolutions per minute of the lower limb through lessening the inertia of the revolutions. The angle made by knee joint was desirable for getting the greatest propulsion in the moving direction.
8. High heel was lower than barefoot or jogging shoes in the displacement of the center of body gravity. This result showed that the displacement of the center of body gravity was made safe by lowering the flexion and extension of knee joint.
