Abstract

The purpose of this study was to evaluate biomechanical characteristics of trekking shoes using 3D Bootie method as mimics barefoot form of F Co. that provides the best comfort and plantar pressure dispersion. The control group is normal trekking shoes of M Co. and K Co.. 13 healthy males measured the foot pressure, EMG and GRF. Collected data was analyzed using One-way ANOVA in order to investigate the effects of each trekking shoes. The results are as follows: Trekking shoe of F Co. was significantly wider in contact area than others at MF and significantly lower in maximum force, peak pressure than others at RF. In the case of muscle activity, acted in the same way as the effect of barefoot walking. In the case of GRF, effectively absorbed the impact force, so it is possible to efficient walking. As a result of the analysis, trekking shoe using of 3D Bootie method of F Co. can be efficient walking by reducing the load of foot during walking.

본 연구에서는 F사가 맨발 보행 효과에서 착안하여 최적의 착화감과 압력 분산의 효과를 트레킹화에 접목시키기 위해 고안한 3D Bootie 공법을 적용시킨 트레킹화에 대한 생체역학적 분석을 수행하였다. 이를 위해 비교군으로써 M사, K사의 일반 트레킹화에 대하여, 신체 건강한 20대 남성 13명을 대상으로 보행 시 족저압력분포, 하지 근 활성도, 지면반발력을 측정하여 분석하였다. 연구 결과, F사의 트레킹화는 족저압력 분포에서 넓은 접촉 면적으로 인하여 최대 힘과 최대 압력의 감소를 야기했으며, 보행 시 발의 부하를 경감시켰다. 근 활성도 측면에서는 맨발 보행의 효과와 동일하게 작용했다. 지면반발력에서는 효과적으로 충격력을 흡수하여, 말기입각기 때 더욱 효율적인 보행이 가능하였다. 결과적으로 F사의 트레킹화는 맨발 보행의 장점을 이용한 3D Bootie 공법을 적용함으로써 넓은 접촉 면적으로 인해 보행 시 발생하는 발의 부하를 감소시킬 것으로 사료된다.
