보행 및 계단 내리기 시 에어백 인솔착용이 운동역학적 변인에 미치는 영향

Abstract

Targeting 4 physically healthy men, this study was aimed to analyze kinematic variable and those of wearing led by airbag of their shoes when they walk and step down through ground reaction forces and muscle converter. For a measuring method, right lower legs were set as a standard. After lateral great muscle, rectus femoris muscle, midvastus, anterior tibial muscle, bicephalus femoris, semitendinous muscle, gastrocnemius medialis and lateral gastrocnemius were set as places to measure electromyogram analysis of walking and stepping down as well as ground reaction forces at the same time, the conclusion was deducted as follows. 1. No statistically significant difference was not revealed by change of ground reaction forces from all walking subjects before and after wearing led by airbag. 2. Some statistically significant difference was disclosed by vertical ground reaction forces from all stepping down subjects before and after wearing led by airbag. 3. Some statistically significant difference was revealed by lateral great muscle from all walking subjects before and after wearing led by airbag. 4. Some statistically significant difference was revealed by anterior tibial muscle from all stepping down subjects before and after wearing led by airbag. However, the results showed the decrease of individual muscular activity and the change of ground reaction forces as some statistically significant difference was revealed partially from ground reaction forces and muscular activity. This suggested that wearing led by airbag for a long time could decrease muscle fatigue and stabilize ankles from impact against ground and that it could be expected to provide a method to prevent muscular skeletal diseases of people standing for a long time work.
