Abstract

This study investigates the effect of changes in posture caused by wearing high-heeled shoes on the maximum lifting capacity. Nine female college students, ages 20 to 25 years, participated in this study. Three heel heights (flat, 5 cm and 7.6 cm), two lifting heights (floor to knuckle and knuckle to shoulder), and lifting frequency of 4 per minute were examined. The results indicate that a significant difference exists between MAWOL with flats and that with 7.6 cm heels for both lifting heights. Subjects lifted 21.5% less weight using 7.6 cm heels than wearing flats. No significant difference was found between MAWOL with flats and 5 cm high heels. In addition, in evaluating the tasks subjectively, the subjects reported that they experienced a stress ontheir legs when lifting with 5 cm and 7.6 cm high-heeled shoes. The conclusion of this study indicates that a change in posture affects lifting capacity, and individuals should adjust their predetermined MAWOL while wearing high-heeled shoes. © 1994.
