선발 굽의 높이와 선발착용기칸이 대퇴근육활동량에 며치는 영향

Abstract

This study was conducted to identify the effects of high-heel shoes on EMGactivities of rectus femoris and biceps femoris in 28 healthy women. Subjects werecomposed of experimental group (wearing high-heel shoes) and control group (wearinglow-heel shoes). Two groups participated in three conditions standing (bare footwearing athletic shoes and 7.5 cm height shoes). In high-heel shoes condition, EMGactivities of rectus femoris of control group were significantly lower than that of bicepsfemoris of experimental group, but EMG activities of both muscles of experimentalgroup did not should significant difference. In bare foot standing condition, EMGactivities of rectus femoris of experimental group were significantly lower than that ofbiceps femoris but EMG activities of both muscles of control group had no significantdifference. These results showed that hamstring lengthening effects was produced whenwearing high-heel shoes because the extemal knee extension moment was increased. In the short term, high-heel shoes effect on the increase of the biceps femoris activitiesby spindle reflex, but in the long term, the normal amplitude of the same muscleactivities by Golgi tendon organ reflex.
