목적:본 연구는 복부 할로잉 운동과 복부 브레이싱 운동을 통해 동적 균형에 미치는 즉각적 효과를 알아 보고자 실시하였다. 방법: 성인 남녀 학생 90명을 대상으로 하였고, Y-균형검사와 기능적 팔 뻗기 검사를 이용하여 측정하였다. 결과: 그룹 간의 동적 균형 검사에서, 특히 복부 할로잉 운동을 실시한 그룹과 대조군 사이에 통계적으로 유의한 차이가 있었다. 결론: 대표적인 척추안정화 운동 복부 할로잉 운동과 복부 브레이싱 운동 모두 동적균형의 증가에 있어 유의미하지만, 즉각적 효과라는 측면에서 어떠한 방법이 더 효과적이라고 제시하는 것은 어렵다.

Purpose : This study examined the feedback effect of real-time ultrasound imaging on the thickness of transversus abdominis(TrA), internal abdominal oblique(IO) and external abdominal oblique(EO) during abdominal hollowing exercise(AHE) in crook lying. Methods : We performed this study on 30 healthy men who voluntarily consented to participate in this study after listening to its purpose and method. All subject were divided into an experimental group(n=15) with using the real-time ultrasound imaging feedback(RUIF) and a control group(n=15) without the RUIF The thickness changes between rest and AHE were compared between the two groups in crook lying. Results : The difference in TrA and EO thickness changes between the groups were significant in crook lying (p<0.05). Conclusion : The group with using real-time ultrasound imaging feedback showed a higher increase in the thickness of TrA than the other group without real-time ultrasound imaging feedback. And the thickness of EO in the group with using real-time ultrasound imaging feedback decreased than the other group without real-time ultrasound imaging feedback. If the muscle thickness can be regarded as an indicator of muscle activity, RUIF will be helpful for inducing the independent activity of TrA by reducing the activities of abdominal muscles such as EO.

Purpose : To provide the understanding of abdominal hollowing exercise, this study reviewed literatures related with TrA and AHE. Methods : We reviewed the prior studies related with TrA and AHE. Results : Crook lying is easier to facilitate isolated contraction of TrA from EO than the others. The contraction of the TrA is shown to be the highest muscle activity in prone lying. Additionally, wall support standing(or standing) is shown a higher contraction of entire abdominal muscle than the others. However, learning and teaching correct AHE have innate difficulties in four positions. Conclusion : We have to consider that Rehabilitative Ultrasonic Imaging(RUSI) can facilitate accurate AHE. In the country, physical therapists will be necessary more training and efforts to use ultrasound because very few use ultrasound in clinical field. It will be necessary to study the effects of RUSI feedback and examine effects of exercises in combination with AHE.
