신발의 뒤꿈치 형태가 보행 시 충격과 생체역학적 특성에 미치는 영향

다국어 초록 (Multilingual Abstract)

Objective: The purpose of this study was to investigate the effects of a curved shoe design of the heel of a shoe on the impact variables, ankle joint angle, and COP (center of pressure) during walking.

Background: Shoe design is one of important characteristics in the development of walking shoes as it has to be considered for the mechanism of human movement.

Method: Twenty healthy male adults (age: 23.6±2.9 years, body mass: 71.0±8.7kg, height: 175.8±5.0cm) participated in the study. The data was collected using eight infrared cameras during walking at a speed of 1.3m/s and 1.7m/s on an instrumented treadmill.

Results: The impulse and peak VGRF (vertical ground reaction force) were statistically smaller for the RHS and RLHS compared with the NS during walking of 1.3m/s & 1.7m/s (p <.05). The ankle plantarflexion angle at toe off, the ROM (range of motion) of dorsi-plantarflexion, and ROM of inversion-eversion were statistically smaller for the RHS and RLHS compared with the NS during walking of 1.7m/s (p <.05). The antero-posterior COP range and jerk were statistically smaller for the RHS and RLHS compared with the NS during walking of 1.7m/s (p <.05).

Conclusion: It is concluded that RLHS is slightly effective in reducing shocks, RLHS and RHS help walk smoothly and naturally compared to NS, and RLHS improves the stability of the ankle joints compared to NS, and RLHS during walking.

Application: The findings would be helpful when developing the walking shoes with biomechanical functions.
