Abstract

The purpose of this study was to compare the foot plantar pressure and temperature changes of the developed combat boots with functional impact absorption and ventilation insole. A total of 11 male subjects(age: $21.8{\pm}2.2yrs$, height: $174.3{\pm}3.6cm$, weight: $71.6{\pm}8.6kg$, foot length: $261.0{\pm}1.0mm$) were recruited to compare the foot plantar pressure and temperature changes of the three types of combat boots: Combat boots A (generalized combat boots), Combat boots B (developed combat boots with ventilation function), Combat boots C (Application of ventilation function and impact absorption insole to combat boots B). Pedar-X and a portable thermistor temperature sensor were used to measure the foot plantar pressure parameters and the internal temperature of the combat boots, respectively. One-way ANOVA was used to compare the results of plantar pressure and temperature changes. The results were as follows: First, in the foot plantar pressure parameters, combat boots C showed the significant lower maximum foot plantar pressure in the right/left rear foot compared with combat boots A and average foot plantar pressure in the left foot compared with combat boots B. Second, after 40 minutes from the start of walking, the developed combat boots B and C showed the significant lower temperature than the general combat boots A.

본 연구의 목적은 충격흡수 및 통기기능 인솔을 적용한 개발 전투화의 족저압력 및 온도변화를 연구하는데 있다. 남성 피험자 11명(age: $21.8{\pm}2.2yrs$, height: $174.3{\pm}3.6cm$, weight: $71.6{\pm}8.6kg$, foot length: $261.0{\pm}1.0mm$)을 대상으로 총 3종류 전투화의 족저압력 및 온도 변화를 비교하였다: 전투화 A(보급형 일반 전투화), 전투화 B(통기구가 적용된 개발 전투화), 전투화 C(전투화 B에 통기기능 및 충격흡수용 인솔 적용). 족저압력 측정을 위해 Pedar-X를 사용하였고, 전투화의 내부온도는 휴대용 써미스터의 온도센서를 사용하였다. 전투화의 종류별 족저압력 및 온도 변화결과를 비교하기 위해 일원변량분석(one-way ANOVA)을 실시한 결과, 첫째, 족저압력 변인에서, 기능성 인솔을 적용한 전투화 C가 전투화 A보다 오른발/왼발 후족부의 최대족저압력에서 통계적으로 유의하게 낮았으며, 전투화 C가 전투화 B보다 왼발 후족부의 평균족저압력에서 통계적으로 유의하게 낮은 압력을 나타내었다. 둘째, 내부온도에서 보행시작 후 40분경과 시점부터 개발 전투화인 B, C가 일반 전투화인 A보다 낮은 내부 온도를 보였다.
