| Abstract |
INTRODUCTION
This purpose of this study was to investigate on the change of shoe's heel heights & body weights for dynamic balance on during gait motions in women.
METHOD
We selected subjects of n=15 young and healthy women in 20's age women and divided into 3 group(lean n=5: BMI 18.26±0.15kg/m 2 , Normal n= 5: BMI:
20.64±0.88kg/m 2 , Obese n=5: 29.46±4.72kg/m 2 ) and walked with 3 types of shoe's high- heeled(0cm, 6cm, 9cm). Analysis of the gait was conducted by the image analysis method of 3D DLT(direct Linear Transformation)technique. Variables analyzed were consisted of the time, displacement(Y axis), FR angle & LR angle during gait. Two-Way(body weight 3 × shoe's heel heights 3) repeated measure analyses of variance(ANOVA) & post hoc test(Duncan) were performed to accomplish the study purpose.
RESULT
Time elapsed was shortened according to the body weight increase(p<.05), the COM displacement in Y-axis showed the shorter movement according to increase of shoe's heel heights(p<.05). FR angel in trunk showed the relative forward leaning motions according to increase of shoe's heel heights & body weights(p<.05), LR angle in trunk showed the relative ipsilateral & contralateral trunk leaning according to increase of shoe's heel heights & body weights(p<.05). The effect of LR angle according to increase of body weights showed greater than that of shoe's heel heights during gait(p<.05).
CONCLUSION
Considering the above, the effect on the dynamic balance was decreased according to increase of shoe's heel heights & body weights during gait. |
