The Effect of the Height of the Heel of Pumps and the Age to the Gait Analysis in Wearing Business Pumps
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.40 Vol.40】
ABSTRACT
To find the effect of the heel height of the pumps for businesses and the age on thewalking performance, the 3D motion analysis, the electromyography, the posturalmovements analysis, the foot pressure measurement were conducted for the 7 youngand the 5 middle aged female people. The motion analysis was performed for naked foot and pumps of and heel height 3cm（h3）， 5cm（h5）， 7cm（h7）．We calculated⊿S, which is the difference between the maximum and the minimum value of the gaitcycle curves for the angle, angular velocity, and the angular acceleration of the legjoints of the knees and ankle. The tendency of ⊿S of a right knee joint angle, ⊿S of theright knee angular speed and ⊿S of a right knee angular acceleration became biggestfor 3cm heel pumps（ h3）．In case of long time's walking, the decrease of ⊿S of eachjoint occur for the a middle age group with high heel pumps. The electromyogrambecame highest at the muscle of tibias anterior and the gastrocnemius of 7cm heelpumps （h7）．For postural movements analysis, the length of the track increased inputting on higher heel pumps. For pressure measurements, while a weight track bent byh3 and h5, it was a straight movement in h7. Key words: 3D motion analysis, electromyography, postural movements analysis，foot pressure measurement.
