Abstract

Lumbar stabilization exercise is a popular exercise method in recent clinicians, as it strengthens muscles around the spine and abdominal muscles, but there is a lack of research on the effects of pulmonary function and respiratory pressure. So, this study examined whether abdominal bracing exercise, a typical lumbar stabilization exercise, was effective in pulmonary function and respiratory pressure. In this study, a total of 20's 40 subjects were recruited and randomly divided into an abdominal bracing exercise group(n=20) and control group(n=20). Abdominal exercise group underwent 25 minutes of exercise. Pulmonary function and respiratory pressure values were measured to analyze respiratory function. As a results of the experimental group, there were significant improvements in FVC, FEV1, PEF and MEP(p<.05) and there was a significant difference in the comparison between groups, except the MIP. These results suggest that abdominal bracing exercise can be presented as effective exercises to improve respiratory function.

요부안정화 운동은 척추 주변 근육과 복부 근육을 강화시켜 최근 임상에서 많이 사용하는 운동 방법이지만 호흡기능에 어떠한 영향을 미치는지에 대한 연구는 부족한 실정이다. 이에 본 연구에서는 대표적인 요부안정화 운동인 복부 브레이싱 운동이 정상 성인의 호흡기능에 효과적인지를 알아보고자 실시하였다. 20대 성인 40명을 대상으로 각각 복부 브레이싱 운동을 25분간 실시하는 실험군과 일상생활을 25분간 하는 대조군으로 무작위 배치하였다. 호흡기능의 변화량을 비교하기 위하여 노력성 폐활량, 1초간 노력성 호기량과 최대호기유속을 통해 폐기능 검사를 하였고, 호흡압력의 변화량을 알아보기 위해 최대 호기압력과 최대 흡기압력을 측정하였다. 본 연구의 실험 결과 실험군에서 폐기능과 호흡압력 모두 유의하게 증가되었고(p<.05), 그룹 간 비교에서는 최대 흡기압력을 제외한 나머지 수치에서 유의한 차이가 있었다(p<.05). 이러한 결과는 복부 브레이싱 운동이 호흡기능을 향상시키기 위한 효과적인 운동으로 제시될 수 있다고 사료된다.
