Effect of Yoga Breathing Exercises on Ventilatory Function

Introduction: Controlled breathing not only keeps your mind and body functioning at their best, it can also lower blood pressure, promote feelings of calm and relaxation and help you de-stress. Many experts encourage using the yoga breathing exercises as a means of increasing awareness, mindfulness and reducing anxiety. Over-worked, under-slept, and feeling pressure may impair breathing pattern. There are some yoga breathing exercise techniques that improve ventilator function.Objective: To assess the effect of yoga breathing exercises on their ventilatory function. Methods: Forty eight male and female students of 18 - 30 years were involved in the study of ventilatory function before and after yoga breathing exercise. Pulmonary function tests were performed with the subject sitting in a comfortable chair. Initial recording of tidal volume, inspiratory capacity, inspiratory reserve volume, expiratory reserve volume, forced vital capacity, and timed vital capacity in one second were measured.Results: There was significant increase in inspiratory reserve volume, expiratory reserve volume, vital capacity, forced expiratory volume in one second and forced vital capacity after yoga breathing exercise.Conclusion: Yoga breathing exercise improves ventilatory function.

And Control

This study aimed to compare the effects of cervical stabilization exercises with breathing exercises and cervical stabilization exercises with thoracic spine extension exercises on respiratory function in subjects with forward head posture (FHP). The study included 30 adults with FHP. They were divided into two groups—experimental (EG) and control (CG)—with 15 participants in each group. The EG was asked to perform cervical stabilization exercises with breathing exercises, and the CG was asked to perform cervical stabilization exercises with thoracic spine extension exercises. After 4 weeks of exercise, the changes in respiratory function were measured again. The results showed significant differences in the EG before and after exercise in terms of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF), and forced vital capacity/vital capacity max (FVC/VCmax%) (p < 0.05). The CG showed only a significant increase in FVC, FEV1, and FVC/VCmax% after the experiment (p < 0.05). In the between-group comparison, there were significant differences noted in FVC, FEV1, PEF, and FVC/VCmax% in the EG compared to the CG (p < 0.05). As a result, cervical stabilization exercises with breathing exercises are recommended to promote respiratory function.

The Impact

Background: Video-assisted surgical lung biopsy (SLB) is performed in 10–30% of cases to establish the diagnosis of idiopathic pulmonary fibrosis (IPF). Objectives: The aim of the study was to analyze the impact of SLB on lung function in patients eventually diagnosed with IPF. Methods: This is an observational, retrospective, monocentric study of all consecutive patients eventually diagnosed with IPF in multidisciplinary discussion who underwent SLB over 10 years in a specialized center. The primary end point was the variation in forced vital capacity (FVC) before and after the SLB. The secondary end points were the variations in forced expiratory volume in one second (FEV1), total lung capacity (TLC), carbon monoxide diffusion capacity (DLCO), and morbidity and mortality associated with the SLB. Results: In 118 patients who underwent SLB and were diagnosed with IPF, a relative decrease in FVC of 4.8% (p < 0.001) was found between measurements performed before and after the procedure. The mean FVC decrease was 156 ± 386 mL in an average period of 185 days, representing an annualized decline of 363 ± 764 mL/year. A significant decrease was also observed after SLB in FEV1, TLC, and DLCO. Complications within 30 days of SLB occurred in 14.4% of patients. Two patients (1.7%) died within 30 days, where one of them had poor lung function. Survival at 1 year was significantly poorer in patients with FVC <50% at baseline. Conclusion: In this uncontrolled study in patients ultimately diagnosed with IPF, SLB was followed by a significant decline in FVC, which appears to be numerically greater than the average decline in the absence of treatment in the literature. Summary at a Glance: This study evaluated the change in lung function in 118 consecutive patients diagnosed with idiopathic pulmonary fibrosis by surgical lung biopsy. Forced vital capacity decreased by 156 ± 386 mL in a mean of 185 days between the last measurement before and first measurement after biopsy, representing an annualized decline of 363 ± 764 mL/year.

Before And After

Pulmonary function (PF) is particularly important in synchronized swimming, considering the characteristics of this sport. However, the sanitizing agents (chlorine) used in pools can have a possible negative influence on the PF parameters. In this study, we observed 24 swimmers (all women, 14 to 16 years of age) and measured their PF and competitive achievement. PF was measured before and after a 1-year period and included standard spirometric variables. Competitive achievement was evidenced during the National Championship. The t-test showed significant increases in body height and weight of the participants and a resulting increase in most of the absolute respiratory flows and pulmonary capacities. Forced vital capacity (FVC) and forced expiratory volume (both in proportion to norm for body height, gender, and age) increased significantly within the study period. FVC significantly predicted the competitive achievement of young swimmers, most probably because artists have to achieve exceptional breath control when upside down underwater. In conclusion, we found no evidence for the eventual negative influence of chlorine and its compounds on the PF of swimmers, and results showed that regular synchronized swim training could improve the PF of young artists.

Control Criteria

BACKGROUND: Bronchodilator responses (BDR) are routinely used in the diagnosis and management of asthma; however, their acceptability and repeatability have not been evaluated using quality control criteria for preschool children.OBJECTIVES: To compare conventional spirometry with an impulse oscillometry system (IOS) in healthy and asthmatic preschool children.METHODS: Data from 30 asthmatic children and 29 controls (two to six years of age) who underwent IOS and spirometry before and after salbutamol administration were analyzed.RESULTS: Stable asthmatic subjects significantly differed versus controls in their spirometry-assessed BDR (forced expiratory volume in 1 s [FEV1], forced vital capacity and forced expiratory flow at 25% to 75% of forced vital capacity) as well as their IOS-assessed BDR (respiratory resistance at 5 Hz [Rrs5], respiratory reactance at 5 Hz and area under the reactance curve). However, comparisons based on the area under the ROC curve for ΔFEV1% initial versus ΔRrs5% initial were 0.82 (95% CI 0.71 to 0.93) and 0.75 (95% CI 0.62 to 0.87), respectively. Moreover, the sensitivity and specificity for ΔFEV1≥9% were 0.53 and 0.93, respectively. Importantly, sensitivity increased to 0.63 when either ΔFEV1≥9% or ΔRrs5≥29% was considered as an additional criterion for the diagnosis of asthma.CONCLUSION: The accuracy of asthma diagnosis in preschool children may be increased by combining spirometry with IOS when measuring BDR.

Objective.To evaluate the effects of diaphragmatic breathing exercises and flow and volume-oriented incentive spirometry on pulmonary function and diaphragm excursion in patients undergoing laparoscopic abdominal surgery.Methodology.We selected 260 patients posted for laparoscopic abdominal surgery and they were block randomization as follows: 65 patients performed diaphragmatic breathing exercises, 65 patients performed flow incentive spirometry, 65 patients performed volume incentive spirometry, and 65 patients participated as a control group. All of them underwent evaluation of pulmonary function with measurement of Forced Vital Capacity (FVC), Forced Expiratory Volume in the first second (FEV1), Peak Expiratory Flow Rate (PEFR), and diaphragm excursion measurement by ultrasonography before the operation and on the first and second postoperative days. With the level of significance set atp<0.05.Results.Pulmonary function and diaphragm excursion showed a significant decrease on the first postoperative day in all four groups (p<0.001) but was evident more in the control group than in the experimental groups. On the second postoperative day pulmonary function (Forced Vital Capacity) and diaphragm excursion were found to be better preserved in volume incentive spirometry and diaphragmatic breathing exercise group than in the flow incentive spirometry group and the control group. Pulmonary function (Forced Vital Capacity) and diaphragm excursion showed statistically significant differences between volume incentive spirometry and diaphragmatic breathing exercise group (p<0.05) as compared to that flow incentive spirometry group and the control group.Conclusion. Volume incentive spirometry and diaphragmatic breathing exercise can be recommended as an intervention for all patients pre- and postoperatively, over flow-oriented incentive spirometry for the generation and sustenance of pulmonary function and diaphragm excursion in the management of laparoscopic abdominal surgery.

Experimental Group

The breathing mechanism has existed since our birth and accompanies us throughout life. Breathing is an important function in the regulatory process of numerous body functions, its optimization can bring many health benefits. However, many children are unaware of the mechanisms of breathing, namely abdominal or diaphragmatic breathing, and in addition to this, many breathe normally through their mouths. The present study aimed to verify the influence of a short-term breathing exercise program on children's breathing capacity. Twenty-one children aged between 8 and 10 years were selected, from this selection two groups were formed, the control group (CG) with 10 children and the experimental group (EG) with 11. Through a spirometric test, an assessment of breathing capacity (ABC) was carried out for both groups. The GE participated in a program of breathing exercises (BEP) lasting 15 to 20 minutes for 5 weeks. Then, the ABC was performed again for both groups. The results demonstrate a significant increase in the values (p<0.027) of the forced vital capacity (FVC) of the EG, thus suggesting that the application of a BEP promotes the breathing capacity of school-aged children. Further studies should be performed with larger samples and with a longer protocol.

Background: Air conditioners are used extensively these days of the modern lifestyle. Inhalation of cold dry air while using Air conditioners causes bronchoconstriction due to which alteration may occur in pulmonary function. This study was aimed to compare the Pulmonary Function tests of Car AC users and non AC users. Methods: The Study included 52 employees not exposed to car air conditioner as a control (group I) and 52 employees exposed to car air conditioner with minimum exposure of 1 hour per day for 6 months as a subject (group II). Pulmonary function tests were performed using computerised spirometer. Statistical analysis was done by unpaired t test.Results: Age, Height and weight are not statistically significant between study group and control group. Forced vital capacity, forced expiratory volume in 1 second, Ratio of Forced vital capacity and Forced expiratory volume in 1 second, Inspiratory reserve volume, Expiratory reserve volume, Maximum voluntary ventilation are decreased in car air conditioner users compared to non-users, but was not significant. Forced expiratory flow (FEF), Peak expiratory flow rate (PEFR) values shows statistically significant decreased in car air conditioner users.Conclusions: The present study shows hyper-responsive airways on exposure to cold air which leads to bronchoconstriction. The significant decrease in PEFR, FEF suggest that upper airways as well as smaller airways are affected on exposure to car AC. So, Exposure to car Air Conditioner leads to risk of developing respiratory dysfunction.

Background: Previous studies suggest that obese individuals are prone to pulmonary function abnormalities. The aim of this study was to evaluate pulmonary function tests in obese individuals and to relate pulmonary abnormalities if any found to lipid abnormalities and to the extent and duration of obesity.Methods: This prospective study was done on 40 obese patients attending to Dr. D. Y. Patil Hospital, Mumbai with complaints of pulmonary functions during the period from January to December 2012. Pulmonary function test was done with the help of Jaegers pneumoscreen. The percentage of body fat was determined by using triceps skin fold thickness technique by using Vernier callipers. Fasting serum samples was collected to analyses cholesterol and triglycerides.Results: Female preponderance was seen in the study (57.5%). Forced expiratory volume, forced vital capacity, maximum mid expiratory flow rate was significantly reduced and the ratio of forced expiratory volume in one second to forced vital capacity was significantly increased in individuals who had abnormal pulmonary function. Decrease in pulmonary function was noted with increased levels of cholesterol and triglyceride but the correlation was not significant.Conclusions: Obese individuals although asymptomatic have significant lung function abnormality in the form of restrictive as well as obstructive pattern. Hence, reduction in the body weight may help in reversal of the pulmonary function indices.
