사각근에 대한 수동신장운동이 노력성폐활량에 미치는 영향
변성학 ( Sung Hak Byun ),한동욱 ( Dong Wook Han ) 대한물리의학회 2016 대한물리의학회지 Vol.11 No.1
PURPOSE: The purpose of this study was to investigate the effects of passive stretching exercises of the scalene muscles known as respiratory accessory muscles, on forced vital capacity. METHODS: Ten of the participants were randomly selected as an experiment group to perform passive stretching exercises on the scalene muscles. Ten additional students were selected randomly as a control group. The forced vital capacity was assessed by using a digital spirometer (Pony FX, COSMED Inc, Italy) both before and after the passive stretching exercises were performed. Subsequently, passive stretching exercises of the scalene muscles were performed in the experimental group. There were no interventions to the control group. RESULTS: As for the forced vital capacity (FVC), the experiment group showed significant increase in items of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV₁), peak expiratory flow (PEF), forced expiratory volume in 1 second/vital capacity (FEV₁/VC), and maximal expiratory flow 75%(MEF 75%) after the scalenemuscles passive stretching exercises were performed. The control group, however, showed no change. CONCLUSION: This study demonstrated that passive stretching exercises of the scalene muscles could be helpful for forced vital capacity improvement.

태권도 막기동작 응용 가슴우리 확장운동이 폐 기능에 미치는 영향
변성학(Sung-Hak Byun),하미숙(Mi-Sook Ha),한동욱(Dong-Wook Han) 대한심장호흡물리치료학회 2021 대한심장호흡물리치료학회지 Vol.9 No.1
Purpose : In this study, we aimed to investigate the effects of rib cage expansion exercise applying Taekwondo Makki motion on pulmonary functions. Methods : We examined 30 female university students without any dysfunctions of the nervous, muscular, and cardiopulmonary systems. Pulmonary functions were tested using a digital pulmonary function measuring device (Pony FX, COSMED Inc, Italy). The experimental group performed three movements of expanding their rib cage applying Taekwondo Makki motion. The participants performed exercises twice a day, once in the morning and again in the afternoon, for 4 weeks. The control group did not perform any other exercise. Pulmonary functions were measured again after 4weeks. SPSSWIN (ver 25.0) package program was used for statistical analysis. Results : In the experimental group, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), inspiratory reserve volume (IRV), inspiratory capacity (IC), expiratory reserve volume, vital capacity (VC), and maximal voluntary ventilation (MVV) improved significantly after 4 weeks of exercise; the control group showed no change. The changes in FVC, FEV1, IRV, IC, VC, and MVV in the experimental group were higher than those in the control group. Conclusion : The rib cage expansion exercise applying Taekwondo Makki motion can improve pulmonary functions.

Purpose: The purpose of this study is to determine the effects of exercise of expanding rib cage which applied Taekwondo on pulmonary function. Subjects: Twenty female college students at the age of 19~23 without any functional disability of nervous system, muscular system and cardiopulmonary system were participated. Methods: Pulmonary functions were assessed through the use of a pulmonary function measurement device(Pony FX, COSMED Inc, Italy). The Taekwondo group preformed the seven kinds of movements of expanding rib cage which applied Taekwondo. Every movement was repeated three times and each movement was proceeded for 15 seconds. The control group didn’t perform any other exercise. Afterwards, pulmonary functions were assessed again by the same measuring instruments. The Mann-Whitney test and Wilcoxon sign rank test were used to compare pulmonary functions between Taekwondo group and control group. The statistical program was the SPSSWIN (ver 21.0) package program. Results After the exercise of expanding rib cage, fIC of FVC factors and ERV, Rf and Vt, of SVC factors improved significantly. In comparing the difference of changes of pulmonary functions between Taekwondo group and control group, FVC, FEV1 and fIC, of FVC factors in Taekwondo group increased significantly more than control group. Conclusion: This study revealed that the exercise of expanding rib cage which applied Taekwondo can improve the pulmonary functions.
