서 있는 자세에서 기능성 신발과 운동화의 자세 안정성 비교분석

The aim of this study is to assess the effects of wearing MBT shoes at standing posture on postural stability. The subjects were 9 males(age: 23.7 ± 2.3 yrs, height: 177.8 ±3 .8 cm, weight: 72.7 ± 7.2 kg) in their 20s who exercise regularly and are in good physical health. Two force plate were used. The ground reaction force data were collected in 2000Hz which were divided by the subjects’ weight. In order to assess the stability, the Anterior-posterior Stability Index(APSI) and Medial-lateral Stability Index(MLSI) were calculated based on the ground reaction force data, and the ranges of the Center of Pressure(COP) X, Y, and the sway of the COPE X, Y were examined based on the COP data. The result shows that the stability examined by the APSI were lower when wearing MBT footwear compared to wearing casual footwear (running shoes) and the ranges of the COPE X, Y and the sway of the COP X, Y were larger.
