ABSTRACT
Objective:To explore the effect of abdominal breathing exercises at different periods on the gastrointestinal symptoms, quality of life and proton pump inhibitor dependency in patients with gastroesophageal reflux disease (GERD). To provide reference for patients to choose the best time for abdominal breathing exercises.Methods:This was a prospective study. From March 2020 to December 2021, totally 108 GERD patients were collected in digestive outpatient clinic of Yibin Hospital of Chinese Medicine Hospital by convenient sampling method, they were randomly divided into pre meal group, 1 h postprandial group and 2 h postprandial group with 36 cases in each group. All patients in the three groups were given abdominal breathing training for 8 weeks on the basis of conventional acid suppression drug treatment and nursing. The training time of pre meal group, 1 h postprandial group and 2 h postprandial group was at 30 min before meal, 1 h after meal, 2 h after meal, respectively. Before and after 8 weeks of intervention, the difference of gastrointestinal symptoms and quality of life were assessed by Reflux Disease Ouestionnaire (RDQ) and the MOS 36 Item Short Form Health Survey (SF-36). Patients followed up for 12 weeks after drug withdrawal, the medication of proton pump inhibitor (PPI) between three groups were compared.Results:There was no significant difference in RDQ score and SF-36 score among the three groups before intervention ( P>0.05). After intervention, the symptom scores were (7.89 ± 1.86) in the 1 h postprandial group, lower than in the pre meal group (10.38 ± 1.81) and in the 2 h postprandial group (9.64 ± 1.65), the difference was statistically significant ( t = 5.83, 4.06, both P<0.01). The scores of each demensions in SF-36 were higher in the 1 h postprandial group compared to the pre meal group and the 2 h postprandial group, the differences were statistically significant ( t values were 2.04-3.70, all P<0.05). After followed up for 12 weeks, the PPI discontinuation rate was 71.43% in the 1 h postprandial group, higher than in the pre meal group 44.12% and in the 2 h postprandial group 45.45%, the differences were statistically significant ( χ2 = 5.28, 4.73, both P<0.05). Conclusions:Abdominal breathing exercises at 1 hour after meal can effectively alleviate gastrointestinal symptoms, promote quality of life and decrease the proton pump inhibitor dependency of GERD patients.
ABSTRACT
Background: Yogic relaxation practices produce consistent physiological changes. Various studies are on before and after effects of yoga. There is limited study on physiological changes during yoga. Aim and Objectives: In this study, we explored physiological changes during two yogic relaxation practices using polysomnography instrument. Materials and Methods: Ethical approval for the study was obtained from the Institute Ethics Committee, All India Institute of Medical Sciences, New Delhi. Data were collected in a still, (supine position lying face upwards in Shavasan, before and after performing asanas) for 5 min, 10 min during, 5 min after the yogic relaxation practices (Shavasan and Makrasan). Recording were taken continuously after bio calibration as baseline1, shavasan, baseline2, makrasan, post makrasan. The data of pulse rate, respiratory rate and SPO2 were analyzed using Statistical Package for the Social Sciences version 20. Result: Among 18 participants of age 18–45 years, 11 male and 7 female were participated. Comparison of selected parameters (respiration rate, SPO2, heart rate [HR]) in different condition (baseline1, shavasan, baseline2, makarasan, post makarasan) was analyzed. Comparison of HR in different condition is highly significant; HR varies in makarasan significantly from baseline1, shavasan and baseline2. SPO2 changes significantly vay among different conditions. Changes in respiratory rate are not significant in different conditions. Correlation of age with body mass index is significant in post makarasan variable. Conclusion: Physiological changes occur differently in two different yogic relaxation practices. Further detailed study with large sample size, blood pressure monitoring and in well-trained individuals will provide more information.
ABSTRACT
Respiratory training can prevent and treat nonspecific low back pain, mainly by activating the deep stabilizing muscles of trunk, establishing appropriate intra-abdominal pressure and optimizing the proprioceptive input of lumbar back, so as to maintain the stability and control of the spine. At present, the commonly used breathing training methods in clinic mainly include diaphragmatic breathing, inspiratory muscle training and abdominal breathing. However, the formulation of respiratory training prescriptions and the comparative study of therapeutic effects among different respiratory training methods still need to be further explored.
ABSTRACT
Objective To investigate the effects of abdominal breathing training on sleep disorders in elderly patients with chronic heart failure. Methods Total of 100 patients with chronic heart failure complain of sleeping disorders and Pittsburgh Sleep Quality Index (PSQI)>7 points were assigned into two groups by random digits table method, 50 cases in each group. The observation group and the control group were nursed in the same way except that abdominal breathing was adapted to the observation group. Sleep status, heart rate, blood pressure, SpO2 and brain natriuretic peptide (BNP) were evaluated before training, one week and eight weeks after training respectively. Statistics was used to analyze the differences between two groups. Results After training one week, the sleep status of the observation group was ameliorated, but without significant difference compared to the control group (P>0.05). And after training eight weeks, the PSQI, BNP and heart rate were (9.21 ± 6.38) points, (193.78 ± 152.16) μg/L, (63.5 ± 10.8) times/min in the observation group, and (12.92 ± 0.33) points, (417.55 ± 262.47) μg/L, (70.7 ± 8.5) times/min in the control group, and there was significant differences between 2 groups (t=3.627, 2.041, 2.767, all P 0.05). Conclusions Abdominal breathing training could ameliorate sleep status in elderly patients with chronic heart failure.
ABSTRACT
Objective To evaluate the effect of breathing exercise program (shrinking lips abdominal breathing combined with vertical breathing gymnastics) on dyspnea, pulmonary function, exercise tolerance and quality of life in patients with moderate to severe chronic obstructive pulmonary disease(COPD). Methods A total of 90 hospitalized patients with moderate to severe COPD were randomly divided into the experimental group and the control group with 45 cases in each group. The experimental group lost one case and the control group lost three cases, 86 patients finished the experiment. During hospitalization, on the base of conventional treatment and care, the experimental group received training of shrinking lips abdominal breathing combined with vertical breathing gymnastics after medical staff′s care, with folk music as the background. Exercise frequency:morning, afternoon, 2 times per day, 15 min per time and continue to exercise with researchers′ guidance after discharge. In the control group:take exercises by self, take routine follow-up after discharge. The intervention continued for three months. The indicators such as dyspnea, pulmonary function, exercise tolerance and life quality of both groups were assessed respectively before and after the intervention. Results There were no significant differences in dyspnea symptoms, lung function, exercise endurance, quality of life between two groups before intervention (P>0.05). The dyspnea scored 1.43±0.87 after intervention in the experimental group, and 1.93 ±0.97 in the control group, there was significant difference (Z=-2.293, P=0.022). The 6 min walking test distance was (371.34 ± 67.74) m after intervention in the experimental group, and (301.57 ± 61.67) m in the control group, there was significant difference(t = 4.988, P =0.000). The St. George′s Respiratory Questionnaire (respiratory symptoms, limited activity, influence disease) score and total score were 54.73 ± 11.96, 52.55 ± 14.48, 55.45 ± 10.01, 54.56 ± 10.79 after intervention in experimental group respectively, and 61.19 ± 10.72, 61.35 ± 14.66, 60.48 ± 9.39, 60.93 ± 10.16 in the control group, there were significant differences(t=-2.815--2.397, P0.05). Conclusions The program of shrinking lips abdominal breathing combined with vertical breathing gymnastics can relieve dyspnea in patients with moderate to severe COPD, improve exercise tolerance and quality of life, which is a safe and effective rehabilitation for patients with COPD.
ABSTRACT
Purpose: In this study, we investigated the effects of combining the resistance of an elastic band with slow abdominal breathing on shoulder periarticular muscle activity during shoulder adduction-abduction. Methods: Subjects were eight healthy adult males. Abduction of the shoulder was performed from 0° to 90° (with adduction being defined as the movement from 90°to 0°) for a period of 8 s. The three conditions under which abduction-adduction were performed comprised the following: without an elastic band; with an elastic band; and with an elastic band during slow abdominal breathing. The activities of the biceps brachii, deltoid (anterior, middle, and posterior fibers), trapezius (upper, middle, and lower fibers), and the pectoralis major muscles were measured. Results: Muscle activity of the shoulder periarticular muscles was increased when the elastic band was used. When this was combined with slow abdominal breathing, muscle activity significantly increased in the middle fibers of the deltoid muscle and in the trapezius muscle during abduction while exhaling. Muscle activity significantly decreased in the biceps brachii muscle and the anterior fibers of the deltoid muscle during adduction while inhaling. Discussion: During shoulder abduction, fixation of the trunk occurred initially before the onset of abduction. At this point, exhalation resulted in contraction of the transversus abdominis muscle, a muscle that stabilizes the trunk, thereby enhancing trunk stability and raising the efficiency of deltoid muscle contraction. Conclusion: The results suggested that shoulder abduction performed in combination with slow abdominal breathing increased the efficiency of deltoid and trapezius muscle activities.

ABSTRACT
Objective To study breathing characteristics of normal children of 6～7 years old when speaking in a normal manner.Methods RM 6240 physiological signal collection and processing system and Hx 100 respiratory transducer were used to collect the average peak expiratory pressure,inspiratory valley pressure,respiratory rate,respiratory depth from 160 normally speaking children.Results When speaking,the average peak expiratory pressure,inspiratory valley pressure,respiratory rate and respiratory depth of chest were all significantly increased (P<0.01);while that of abdomen was all reduced(P<0.05,P<0.01)except for respiratory rate(P<0.05)which was increased.In both respiratory conditions,all the data of abdomen were significantly larger than thaf of chest(P<0.01);all the data of boys were larger than that of girls(P<0.05,P<0.01).Conclusion When speaking,it involves thoraco-abdominal breathing,and the increase of chest activity will increase the volume of inhaled air.The increase of abdominal activity is for better control of respiratory airflow.Abdominal breathing plays a main role in normal speaking.Boys'respiratory muscles,respiratory organs are developed better than girls.
ABSTRACT
PURPOSE: This study was done to examine the effects of abdominal breathing on VAS-Anxiety (VAS-A), blood pressure, peripheral skin temperature and saturation oxygen in pregnant women in preterm labor. METHODS: The study design was a matched control group interrupted time series. Forty-six women matched to gestational age were assigned to either the experimental group (26) or control group (20). Data were collected between March 2007 and May 2008. For the experimental treatment the women performed abdominal breathing 30 times, which took 5 minutes, and did one set of 5-minute abdominal breathing daily for three days. Data collection was done before and after the abdominal breathing to measure VAS-A, blood pressure, peripheral skin temperature and oxygen saturation. Descriptive, chi-square, Mann-Whitney U tests were used to analyze the data with the SPSS/PC+Win 15.0 program. RESULTS: For the experimental group there were significant decreases in VAS-A (Z=-4.37, p=.00), systolic blood pressure (Z=-3.38, p=.00), and an increase in skin temperature (Z=-4.50, p=.00) and oxygen saturation (Z=-3.66, p=.00). CONCLUSION: These findings suggest that abdominal breathing in pregnant women in preterm labor results in decreases in anxiety(VAS-A) including biological evidences such as systolic blood pressure, and increases in peripheral skin temperature and oxygen saturation. Further longitudinal study is needed on the lasting effects and obstetric and neonatal outcomes following abdominal breathing.

PURPOSE: This study was to determine the effects of abdominal breathing training using biofeedback on stress, immune response, and quality of life. METHOD: The study design was a nonequivalent control group pretest- posttest, quasi-experimental design. Twenty-five breast cancer patients who had completed adjuvant chemotherapy were enrolled. The experimental group(n=12) was provided with abdominal breathing training using biofeedback once a week for 4 weeks. State anxiety, cancer physical symptoms, serum cortisol, T cell subsets(T3, T4, T8), NK cell and quality of life were measured both before and after the intervention. RESULT: Though state anxiety, cancer physical symptoms, and serum cortisol were reduced after 4 weeks of abdominal breathing training using biofeedback, there was no statistical significance. It showed, however, improvement in quality of life (p=.02), and T3(p=.04). CONCLUSION: Abdominal breathing training using biofeedback improves quality of life in breast cancer patients after a mastectomy. However, the mechanism of this beneficial effect and stress response requires further investigation with special consideration in subject selection and frequency of measurement. Nurses should consider this strategy as a standard nursing intervention for people living with cancer.

Abdominal breathing is an effective training method for relaxation.It is applicable for resolving sub-health problems in autonomic nervous malfunction and curing some kinds of psychosomatic disorders.In order to improve its training effect,we develop a kind of abdominal breathing training instrument on the basis of the principle of biofeedback.With both features of biofeedback and breathing training apparatus,it may simultaneously feedback the training effect to the trainer during the abdominal breathing training,and the trainer may regulate his breathing mode for desirable effects.In this paper,the instrument is described in such aspects as the circuit design,composition and clinical application.It is an economical,safe and effective instrument,which can be used in Health Promotion Project.
ABSTRACT
We analyzed time-domain parameters (%RR50, CVRR, E/I ratio) and frequency-domain parameters (HF, LF, LF/HF, HF/SUM) from R-R interval variability to investigate the differences in autonomic nervous system activity and the effects of abdominal breathing in 20 healthy female subjects (age 48.4±5. 5 years) . The measurements were taken during spontaneous breathing in a supine position for 20 min and in a sitting position for 20 min, followed by voluntary control of abdominal breathing (expiration to inspiration time ratio was 2 to 1) for 20 min and recovery with spontaneous breathing in a sitting position for 30 min, 100 R-R intervals 16 times for 90 min and also heart rate (HR), blood pressure (BP), respiratory frequency (f) and arterial O<SUB>2</SUB> and CO<SUB>2</SUB> partial pressure through cutaneous (P<SUB>tc</SUB>O<SUB>2</SUB>, P<SUB>tc</SUB>CO<SUB>2</SUB>) . The subjects were grouped according to the mean values of three autonomic nervous system activity parameters (%RR50, CV<SUB>RR</SUB>, E/I ratio) in a supine position. Group 1 (G 1) was below average for all three parameters, group 3 (G 3) was above average and group 2 (G 2) was below or above average mixed for the three parameters. A strong correlation (P< 0.01, respectively) was observed between %RR50 and HF (0.15-0.4 Hz) during the following trials spontaneous breathing in a supine position (r=0.783) and sitting position (r=0.758), voluntary control of abdominal breathing (r=0.597), and recovery with spontaneous breathing in a sitting position (r=0.756) . With regard to the characteristics of each group, the following were observed: G1 showed an accelerated trend of sympathetic nervous system activity and the approximate mean value was indicated in measurements of respiratory-circulatory system activity (HR, f, BP) . G2 showed an unstable trend in which either sympathetic or parasymathetic nervous system activities were accelerated, blood pressure was higher and many respiratory frequencies were observed among the three groups. G 3 showed an accelerated trend in parasympathetic nervous system activity ; and both blood pressure and respiratory frequency were consistently low in the three groups. These results indicated that there were natural differences in each subject in autonomic nervous system activity and physiological function in a supine position at rest. It was found that voluntary control of abdominal breathing enhanced the vagal modulation of the heart rate in subjects who showed an accelerated trend of sympathetic nervous system activity.
ABSTRACT
BACKGROUND AND OBJECTIVES: Many patients who have voice disorders simply use too much effort and strain when they speak or sing and create too much laryngeal muscle tension. Therefore voice therapy have been a viable adjunct to surgery and pharmachological therapy for the management of voice disorder. No definitive data exist about the efficacy of techniques used in voice therapy. Moreover, aerodynamic and acoustic analysis according to respiration and phonation methods has seldom been reported. MATERIALS AND METHODS: In this study, healthy adults with natural breathing, abdominal breathing, and abdominal breathing with resonant phonation were analysed by aerodynamic and acoustic method. RESULTS: In the order of natural breathing, abdominal breathing, and abdominal breathing with resonant phonation, maximum phonation tended to increase, but without statistical significance. In both sex, the fundamental frequency, mean airflow rate, intensity tended to increase and glottal resistance tended to decrease at abdominal breathing and abdominal breathing with resonant phonation than natural breathing, but without statistical significance, except in easy voice. In female, jitter and shimmer were decreased and NHR was increased at abdominal breathing with resonant phonation and the improvement of acoustic aspects was significant. CONCLUSION: A change of mode of respiration and phonation which inspire more air and control subglottal pressure properly was found to reduce the glottal adduction and increase the vocal efficiency. This respiration and phonation method appear to enhance normal vocal function especially in female who is apt to have more voice disorders than male.
