Effect of Tight-fitting High-heeled Shoes on the Activities of the VMO, BF, and GCM Muscles during Stair Ascent

Abstract

Abstract.[Purpose] The purpose of this study was to investigate the effects of tight-fitting high-heeled shoes on vastus medialis oblique (VMO), biceps femoris (BF), and gastrocnemius (GCM) during stair ascent. [Subjects] Fifteen female subjects were recruited.[Methods] The subjects ascended stairs with a step height of 20 cm wearing loose-and tight-fitting high-heeled shoes, and the activities of the VMO, BF and GCM muscles were recorded using EMG.[Results] The normalized EMG data of the VMO muscle significantly decreased when wearing the tight highheeled shoes during ascend the stair when compared to the loose high-heeled shoes. The normalized EMG data of the BF, and GCM muscles significantly increased when wearing the tight high-heeled shoes during stair ascent compared to the loose high-heeled shoes. [Conclusion] We think that tight-fitting high-heeled shoes may more easily cause muscle imbalance; therefore, tight-fitting high-heeled shoes would raise the risk of musculoskeletal disorders in young women.

“…Wearing of HHS is more common in between young females 22 . Furthermore, especially tight-fitting high heeled shoe has been prefered 23 . High heels are not only foot accessories but also an significant part of fashion that reflects her personality 24 .…”

“…This change in position translates into a higher vertical ground reaction force on the forefoot and shock absorber mechanisms like knee, ankle or inverters can not work 30 . As a result, all these effects blood circulation and lymph fluid by restricting 23 .…”
