본 논문은 만성폐쇄성 폐 질환이 흡연, 대기오염으로 많은 질환자가 발생하여 재활운동을 필요로 하는 추세이다. 현재 측정 도구와 재활운동 도구가 분리되어 질환 진단은 한정된 시설을 이용해야만 하고 재활운동 또한 상시 진행할 수 없어 질환을 확인하기 어려운 실정이다. 이에 평상시 착용하는 이너형태에 재활운동 의류를 개발하여 올바른 호흡을 돕는 근육군이 동원하여 복식호흡을 유도하고 흉식호흡 시 웨어러블기기를 통해 인지하게 돕는다. 이 결과 일상 속 지속 가능한 재활운동을 바탕으로 가슴 벽의 호흡근육 활동을 감소시키고 복부 근육군을 개선하는 것으로 폐 기능을 증진시킬수 있는 언더웨어 개발을 제안하고자 한다.

The development of smart healthcare wearables for health is accelerating. Among them, many wearable products using EMS electrical stimulation, which is one of the active research fields, have been released. However, the EMS wearable, which has been studied or released, is released in a comprehensive full-body suit that does not focus on muscle segmentation or a belt that covers the entire abdomen. Therefore, this study intends to use two breathing methods by applying an EMS pattern that subdivides specific muscles and attach a stretch sensor that can measure breathing to the abdominal pressure belt. The measurement method was conducted by inhaling and exhaling, and the subjects were 10 men in their 20s with healthy bodies. As a result of this study, the sensor's sensitivity was 5 and 3 mm, and the basic sensor in both thoracic and abdominal breathings and the EMS abdominal pressure belt showed improved respiration activation after applying electrical stimulation before and after application. It is concluded that, because of the two patterns produced based on the physical function, the difference in respiration activation effect and sensitivity between sensors could be confirmed with three sensors rather than not applying electrical stimulation suitable for the respiration method. Based on the results of this study, a follow-up study aims to develop breathing smart clothing that can be monitored in real time in clothing-type wearable products that incorporate EMS patterns and stretch sensors.

The effect of abdominal respiration on electrocardiogram readings was examined using a 12-lead ECG in healthy young adults. Ten males and ten females without any cardiac and/or pulmonary problems participated in this study. ECG readings during periods of abdominal respiration and thoracic respiration were compared using a paired t-test. Results showed that the PR interval was longer in males compared to females during the period of abdominal respiration (p<0.05). There were no differences in amplitudes of the P, R, T waves, QTc, and degree of P axis between abdominal respiration and thoracic respiration in both male and female subjects. However, degrees of QRS axis in male subjects (p<0.05) and T axis (p<0.05) in female subjects were increased during the abdominal respiration. Therefore, abdominal respiration may cause positive electrical axis changes in the depolarization and relaxing re-polarization of the ventricles.
