“…The activity of the quadriceps was enhanced and that of the GCM was reduced when female workers ascended stairs wearing high-heeled shoes 7) . However, in the present study, the GCM muscle activity significantly increased and that of the VMO muscle decreased when subjects wore the tight-fitting high-heeled shoes during stair ascent.…”

“…Yoo et al 6) also suggested the need for studies into the relationship between musculoskeletal disorders and the wearing of tight-fitting garments. The effects of type and height of shoe heels on the body have revealed that the lower extremity mechanics and the energy cost differ with heel height 7) . However, few studies have investigated the effects of wearing tight-fitting highheeled shoes.…”

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.

“…It is considered that gastrocnemius muscle tension increased due to the anterior wedge board. Thus, the gastrocnemius muscle acted more on knee extension, thereby relatively reducing the activity of the quadriceps muscles 7) . In this study, when the lunge exercise was applied with a medial wedge board, significant increases in VMO/VL ratios were shown along with high activity of the VMO.…”

Abstract. [Purpose] This study applied the lunge exercise using a variety of foot wedge boards to analyze differences in the muscle activities of the vastus lateralis (VL) and vastus medialis oblique (VMO) and the VMO/VL ratios. [Subjects] This study was performed on 20 asymptomatic males.[Methods] Surface electromyography measurements were obtained under 5 lunge exercise conditions. [Result] The EMG activity for the VL muscle significantly increased in the order of conditions as follows: anterior wedge < no wedge and medial wedge < lateral wedge and posterior wedge. The EMG activity for the VMO muscle significantly increased in the order of conditions as follows: anterior wedge < no wedge and lateral wedge < medial wedge and posterior wedge. The VMO/VL ratios under the medial wedge and posterior wedge conditions were significantly increased.[Conclusion] Use of medial and posterior wedge boards during the lunge exercise can selectively strengthen the VMO.

“…Atividade mais intensa do quadríceps ocorre quando o momento flexor do joelho aumenta devido à inclinação da articulação do tornozelo proporcionada pelo uso do salto alto (3,(24)(25)(26). Isso ficou confirmado no presente estudo, com o aumento da atividade eletromiográfica de todos os músculos quando realizadas as tarefas com o calçado de salto alto.…”

concêntrica e excêntrica realizadas com salto alto. No entanto, no grupo SDFP, a atividade do VMO não foi influenciada em nenhuma das condições testadas. Não foram observadas diferenças estatísticas na razão VMO/VL e no tempo de ativação dos músculos. Conclusão: Os resultados sugerem que em mulheres assintomáticas uso do calçado de salto alto modificou a atividade de todos os músculos. Entretanto, mulheres com SDFP não apresentaram alterações no VMO. [P] Palavras-chave: Síndrome da dor femoropatelar. Eletromiografia. Sapatos.[ [K]
