[INTRODUCTION] The purpose of this study was to analyze lower limb muscle activity according to change
weight and high-heeled height.
[METHOD] We selected 30 young and healthy women who have been wearing high-heeled shoes for one year or more. The women were divided into 3 groups and walked with 3 high-heeled shoes(4, 7 and 9㎝) on a treadmill for 5min at 2m/sec. These Data were characterized by EMG measurements of three muscles(Tibialis anterior, Gastrocnemius, and Soleus muscle) while they were walking. The resting time was 5 min.
[RESULT] In weight change, there was a significant difference in Tibialis anterior(p<.05). In the result of Tibialis anterior multiple comparisons, there was a significant increase in 40kgs as compared to two groups(50kgs, above 60kg). In high-heeled height change, there was a significant difference in Soleus muscle(p<.05). In the result of group multiple comparisons regarding heel hight, there was a significant increase in 9㎝ group compared to two groups(4㎝, 7㎝).
[CONCLUSION] The less weight was, the more tibialis anterior was acted. The higher heel height was, the more soleus muscle was activated on walking than Gastrocnemius.
