호흡은 우리가 일상 생활에서 발화나 발성을 하는데 있어서 크기와 높낮이를 조절하는 중요한 역할을 하며 그 중에서 복식 호흡이 가장 이상적인 호흡이라 할 수 있겠다. 우리 인간이 처음 태어날 때는 복식 호흡을 가지고 태어난다. 예를 들면 갓난아이가 울 때 보면 배가 많이 움직이는 것을 볼 수 있으며 긴 시간을 울어도 울음의 소리의 변화가 거의 없다. 허나 성인이 갓난아이처럼 긴 시간을 운다면 울음소리의 변화가 온다. 이것은 우리 인간이 성장하면서 복식 호흡의 사용이 점차 줄고 흉식 호흡의 사용이 보편화되는데 그 이유는 우리 인간의 일상생활에서 복식 호흡이 크게 필요치 않기 때문이기도 하며 특히 여성의 경우는 대부분이 흉식 호흡을 사용하는데 갓난아이일 경우 남아나 여아가 복식 호흡을 사용하나 여아의 경우 성장하면서 즉 여아에서 여성으로 신체적 변화(첫 배란)가 시작되면서 호흡사용의 변화가 있지 않나 생각된다. 여성으로의 신체적 변화는 임신을 할 경우 자궁에서 태아의 성장에 자극을 피하기 위하여 흉식 호흡을 사용하며 성악도인 경우 여성이 남성보다 복식 호흡의 습득에 어려움이 있다 대부분의 여성 성악가의 경우 복식 호흡과 흉식 호흡의 중간을 사용한다.

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.

Background: Studies on the effect of abdominal or thoracic breathing therapy on sleep or blood oxygen concentration are still scarce. Purpose: This study was to examine the effect on blood oxygen saturation and pulse variability, changes in the severity of insomnia, changes in wakefulness before sleep, and dysfunctional beliefs and attitudes toward the Korean version of sleep in women in their 50s after healing with abdominal breathing and thoracic breathing. We investigated the effect. Methods: Subjects were investigated before and after the change of breathing (breathing) therapy for 12 weeks, 3 times a week, and 36 breaths perweek. Results: It wa evaluated respiratory healing as having no significance in the pulse rate change. However, oxygen saturation was significant in the experimental group, increasing to 93.60 SpO₂% before the respiratory rally and 96.5 SpO₂% after respiratory recovery (p < .002). In addition, the insomnia severity scale and dysfunctional beliefs about sleep significantly decreased after respiratory rally than before (p < .000). Conclusions: It evaluated that respiratory therapy for the subjects is beneficial to health as it is effective for insomnia, pulse, and oxygen saturation.

본 연구는 복식호흡을 병행한 척추 안정화 운동이 요통환자의 균형능력과 통증에 미치는 영향을 알아보기 위해 시행되었다. 20대 요통환자 18명을 대상으로 하였으며 실험군은 척추안정화 운동을 실시하는 동안 복식호흡을 함께 적용하였으며 대조군은 척추안정화 운동만을 시행하였다. 운동은 8주간 적용하였으며 운동 시작 전과 후에 오스웨스트리 요통장애지수 설문지를 사용하여 통증을 비교하고 BioRescue를 사용하여 신체중심이 이동한 길이와 면적을 측정하여 균형능력을 비교하였다. 실험결과, 두 그룹 모두 운동 후, 요통장애지수가 유의하게 감소하였으나 그룹간의 유의한 차이는 없었다. 신체중심이동면적 비교에서 실험군은 운동 후 유의한 감소가 있었으나 그룹간의 유의한 차이는 없었다. 신체중심이동길이의 비교에서 눈을 감은 상태에서 실험군은 유의한 차이가 있었으나 대조군은 유의한 차이가 없었으며 그룹간 비교에서도 유의한 차이가 있었다. 이러한 결과를 통해 요통환자에게 안정화운동과 복식호흡을 함께 병행하여 실시한다면 더욱 효과적일 것이라고 생각된다.

일반적으로 가창을 위한 호흡법으로는 두 가지를 들 수 있다. 가슴의 횡격막 부분을 사용하는 복식호흡법과 배꼽 밑 부분의 아랫배를 활용한 단전호흡법으로 나눌 수 있다. 일반적으로 윗배를 사용하는 복식 호흡법의 경우 주로 성악 발성에서 사용 하였으며, 아랫배를 활용한 단전호흡법의 경우 창이나 판소리 등의 국악 창법에 많이 사용되었다. 상대적으로 역사가 짧은 대중음악의 경우는 특정한 호흡법이 없고 누구에게 배웠느냐에 따라 호흡하는 방법이 결정되었다. 그러나 매스미디어가 발전함에 따라 대중음악 분야도 발전하게 되었고, 대중가요 가수들을 위한 독창적인 호흡법도 절실히 필요하게 되었다. 따라서 본 연구에서는 가창력을 증진 시킬 수 있는 효과적인 호흡법을 제시해 보고자 한다.

The purpose of this study was to investigate the effects of 12 weeks of abdominal breathing exercises, through AB spur, on weight and BMI, % body fat, and waist-hip ratio in healthy college students. The subjects consisted of 20 obese young college students, and all of whom had no other health complications. The subjects were shown in detail the proper way to utilize the equipment and practice abdominal breathing in a laboratory setting. They were told to wear the AB spur for at least six hours a day in order to induce abdominal breathing exercise. Because the subjects were students, most of the abdominal breathing exercises took place while they were sitting in lectures at school, and they wore the equipment for 12 weeks. At 4, 8, and 12 weeks after the subjects started using the AB spur, there were significant decreases in weight, % body fat, BMI, and waist-hip ratio (p<0.05). In conclusion, the results of the stud suggest that abdominal breathing exercise may be a good weight loss method, as well as a beneficial way to decrease obesity factors, in obese college students.

This research is to find out which position is more effective on exercise. This study compared paricipants in their twenties on sitting position & standing position doing abdominal breathing of their respiration & abdominal muscle activation for 4 weeks. In sitting position, FEV1 was the biggest after breathing exercise. In standing position, the gap was biggest between the FEV1 & forced expiratory flow before and after the exercise. In standing and supine position, Lt. rectus abdominis before exercise and Rt. rectus abdominis after exercise muscle activities were the biggiest. Both posture exercise of repeated measure of analysis result, before and after the exercise of the rectus abdomonis muscle and external oblique muscle were not difference in both muscle activity(p>.05). Left Musculus obliquus externus abdominis before and after physical exercise, it's showed a meaningful difference(p<0.05). Before and after exercise, saw a meaningful difference the efforts of FEV1/FVC(p<0.05). The left external oblique abdominis muscle showed the most muscle activity in the supine position before/after exercising, the efforts expiratory showed the lowest muscle activity.The results from the repeated measures ANOVA regarding to before/after the volume and muscle activity, it showed significant difference between at the right rectus abdominis muscle(p<.05). This study finally gathered data about the muscle activity according to the position. This could be used to find in what position the abdominal breath exercise is the post effective & a new treatment for the patients who has worsened respiration function.

The purpose of this research was to investigate the effects of respiratory rehabilitation using a wind instrument for patients suffering from spinal cord injuries. From January 15, 2018 to April 15, 2018, we conducted ten 1-hour sessions of a harmonica program with eight patients with spinal cord injuries with average age of 37 years who could not perform abdominal breathing by themselves. We measured and compared patients' breathing capacity before and after the 10 sessions. Designed particularly for patients with spinal cord injuries resulting in a limited range of neck movement, the study used a 10-hole diatonic harmonica whose length was relatively short. For those patients who had difficulty using their hands, a harmonica holder was provided. Participants were trained to play simple tunes. They were guided to use abdominal breathing to make sounds, with emphasis on those parts requiring long and strong breathing. The results showed that for all eight patients both their breathing volume and their inspiratory volume increased following participation in the harmonica program. Also, the program had psychological benefits (e.g., more life satisfaction and less sadness) and additional physical benefits (e.g., less dizziness due to low blood pressure and better phlegm spitting). This study offers a unique way to help patients with spinal cord injuries to improve their breathing capacity, which may also be associated with a greater quality of life.

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.

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.
