초록

본 연구의 목적은 복부 브레이싱 기법을 적용한 척추 안정화 운동, 척추 안정화 운동이 요부 등속성근기능과 폐기능에 어떠한 영향을미치는지 알아보고자 하는데 있다. 이를 위해 여대생을 대상으로 복부 브레이싱 기법을 적용한 척추 안정화운동집단(BSE; 6), 척추 안정화 운동집단(SE; 6), 비 운동집단(CON; 6)으로 나누어 실시하였다. 복부 브레이싱 기법을 적용한 척추 안정화 운동은 8주 간(주 3회, 총60분) 운동을 실시하였다. 운동강도는 운동자각도(RPE)를 활용하여 가볍다(보그 지수; 11)에서 다소힘들다(보그 지수 13) 사이로 목표치를 설정하였다. 자료처리는 SPSS 24.0버전을 이용하여 반복측정 분산분석(repeated Measure ANOVA), 대응 표본 t검정를 실시하여다음과 같은 결론을 얻었다. 첫째 요부 체중당 최대근력에서는 BSE집단과 SE집단이 각속도 60°/sec, 90°/sec 요부근력이 유의하게향상되었으며 120°/sec 에서는 BSE집단에서만 유의한 증가를 가져왔다. 둘째, 체중 당 총일량은 BSE집단에서 신근과 굴근 모두 증가한 것으로 나타났다. 셋째 신근/굴근 비율에서도 BSE집단이 각속도 60°/sec에서 유의하게 증가한 것으로 나타났다. 넷째, 폐기능은FVC, FEF, FEV, FEF25-75%, PEF는 모두 유의한 결과가 나타나지 않았다. 결론적으로 8주간의 복부 브레이싱 기법을 적용한 척추 안정화 운동프로그램이 척추 안정화 운동프로그램만 실시한 경우보다 더 긍정적인 효과 있다는 것을 알 수 있었으며 젊은 여성들의 요통 예방에 긍정적인 영향을 줄 것으로 사료된다.

The purpose of this study is to verify the effect of spinal stabilization exercises using abdominal bracing technique for 50 min, conducted three times a week for 8 weeks for the female college students on their lumbar muscle strength and pulmonary function. The subjects were 18 female students in college located in C city, Korea who did not work out. Specifically, they divided into three groups; Abdominal bracing with spinal stabilization exercises (BSE, n=6), Spinal stabilization exercises (BSE, n=6) and Control group (CON, n=6). BSE Group received additional education of bracing technique before exercise so that they could carry out bracing technique during the spinal stabilization exercise. The was measured by Biodex System pro Ⅲ and the pulmonary function was measured by Spirometer. The flexion and extension exercise were conducted 5 times at angular speed of 60°/sec, 10 times at 90°/sec and 15 times at 120°/sec to investigate the muscular function of lumbar joint and moreover, the pre-test and post-test of the peak torque/body weight and total work/body weight and extension/flexion ratio was carried out. And for the pulmonary function, the pre-test and post-test of force vital capacity (FVC), forced expiratory volume in 1 second (FEF1.0), percentage of forced expiratory volume in 1 second (FEF1%: flow; PEF) and the forced expiratory flow (25-75%; FEF25-75%) was conducted. Furthermore, Repeated measurement ANOVA and the paired t-test were conducted to reveal the difference according to the 8 weeks workout program. The significance level (α) was set at 0.05.
To summarize the research results, the interaction effect was significant in f=6.474, p=.009, according to the time by group for the lumbar extensor strength at the 90°/sec by weight and also, BSE Group and SE Group increased while the CON Group decreased. For the difference between groups, Moreover, there were significant increase in the lumbar flexor muscle at 60°/sec(t=-3.468, p=.018), lumbar extensor strength at 60°/sec(t=-3.989, p=.010), lumbar flexor muscle at 120°/sec(t=-3.026, p=.029) and the lumbar flexor muscle at 120°/sec(t=-2.887, p=.034) only in BSE Group. The difference between rate of extensor muscle/flexor muscle was statistically significant in the interaction effect of time and group (f=4.440, p=.031). Despite of increase in BSE Group, both SE and CNO groups decreased. The variables that measures the pulmonary function increased numerically in the group where operated the workout program but there was no statistically significant difference.
This research investigated that abdominal bracing spinal stabilization exercise could significantly increase the lumbar spine stabilization of female college students. Therefore, it’s expected to have more positive result for the long-term work out and the further research–which is more effective–will be conducted, based on the results of this research.
