Purpose: Dynamic Neuromuscular Stabilization (DNS) approach is developed based on neurodevelopmental kinesiology and reflex-mediated core stabilization concepts. But the outcomes of this approach remain unclear. So changes in some spirometry indices in response to DNS breathing exercises in sedentary students with poor posture will be explored. Methods: In this single-group pretest-posttest study design, we involved 26 male volunteer sedentary students with poor posture. First, a pretest of the spirometry indices (Maximum Voluntary Ventilation (MVV), Forced Expiratory Volume in first second (FEV1), Forced Vital Capacity (FVC), and FEV1/FVC ratio) were done each participant in random order. DNS breathing exercise protocol (six times a week, for six weeks) were trained and after completion of training, the post-test of the same parameters was performed. Descriptive statistical and the paired-sample test were used to analyze. Results: The findings of data analysis indicated that the effect of DNS breathing exercise on respiratory function and significant improvements were observed in post-test compared with pre-test in the following parameters: MVV (178.0±21.

Objectives: Dynamic Neuromuscular Stabilization (DNS) approach evaluates and activates the spinal stabilizers to optimize the performance of posture and respiratory system. This study investigated the effects of DNS breathing exercises on upper and lower chest wall mobility (UCM and LCM), trunk extensor endurance, and thoracic kyphosis in a group of sedentary students with poor posture. Methods: In this randomized, controlled 6-week trial, 52 participants were randomly divided into two groups: a DNS breathing exercise group (n=26) and a control group (n=26). First, a pre-test of the UCM, LCM, trunk muscle endurance and thoracic kyphosis was done on each participant in random order. DNS breathing exercise protocol (six times a week for six weeks) was implemented and after its completion, all post-test parameters were taken. Descriptive statistical and the paired-sample t test were used to analyze the obtained data. Results: Significant improvements were observed in the post-test compared with pre-test in DNS breathing exercise group in UCM (6.2±1.6 vs 4.4±0.9 cm, P<0.001), LCM (7.7±1.7 vs 5.5±1.0 cm, P<0.001), trunk muscle endurance (110.1±33.5 vs 88.7±34.1 s, P<0.001), and thoracic kyphosis (146.9±5.5 vs 142.7±4.0 degree, P<0.001). In contrast, the change in these parameters in the control group was not statistically significant. Discussion: DNS breathing exercise with a focus on the integrated spinal stabilizing system and breathing techniques is an effective protocol to significantly improve UCM and LCM, trunk muscle endurance, and thoracic kyphosis. It is suggested that DNS breathing exercises be introduced to improve chest mobility and posture and provide physiological stabilization for the overall health and performance of student

Worldwide, university students’ physical health and posture are declining due to a sedentary lifestyle. The aim of our study was to evaluate the effectiveness of physiotherapeutic breathing exercises on posture and spinal mobility among healthy female university students compared to other training methods. Sixty-one female students of the University of Debrecen were assigned to breathing exercise (BE; n = 15), yoga (Y; n = 16), Pilates (P; n = 15) programmes and interval-training (IT; n = 15). Each training session lasted one hour, performed twice a week for 7 weeks. Students were assessed using standardized clinical tests. All programmes resulted in significant improvement in chest expansion. Results of Schober’s test showed substantial improvement using BE (p < 0.05), Y, P (p ≤ 0.01) programmes. Significant changes in occiput-to-wall distance (Y, P p ≤ 0.01) (BE p ≤ 0.001) were observed in three groups except the IT group. Fingertip-to-floor test (Y, P p < 0.05) results show...
A Study to Find the Efficacy of Core Stabilization Exercise on Respiratory Functions
International Journal of Life Science and Pharma Research
Core stabilization exercise has become a well-known trend in fitness. The diaphragm, which is a component of core stability, plays a role in respiration and stabilizing the trunk by controlling intra-abdominal pressure. Abdominal exercises, such as sit-ups and leg lifts, are used to enhance the strength of the core muscles. Correct breathing (especially as it involves the respiratory muscles) is vital to abdominal training because respiratory muscles are directly involved during common core stability exercises. This is an experimental study where pre and post design is used. This study was done on a healthy population; a total number of 30 subjects were taken according to the inclusion criteria. 15 subjects in Group-A received five core stabilization exercises combined with diaphragmatic breathing with pre and post-test analysis and 15 subjects in Group-B received resting breathing and diaphragmatic breathing with pre and post-test analysis. 6-Minute Walk Test (6MWT), Forced Expirat...

Background: Pulmonary function parameters can be altered with the change in body position. Therefore, physiological basis behind such consequent influence is essential to be understood. Pulmonary function tests are generally conducted in the erect sitting posture as it is more feasible and comfortable. However, bedridden patients are unable to do so and only few studies are found on recumbent postures. Thus, to comfort such patients in breathing, need arises to meet this requisite investigation to conclude the best recumbent body posture. Aim and Objectives: To compare and assess forced vital capacity (FVC), forced expiratory volume in 1 second (FEV 1), FEV 1 /FVC ratio, forced expiratory flow of during 25-75% expiration (FEF 25-75% , and peak expiratory flow rate (PEF) in the Supine, Crook-lying and Fowler's position. Materials and Methods: The present research was carried out on 128 healthy adults to measure FVC, FEV 1 , FEV 1 /FVC ratio, FEF 25-75% and PEF using a computer-based spirometer in the Supine, Crook-lying and Fowler's position. One-way Analysis of Variance with Tukey HSD post-hoc test was utilized between each body postures by evaluation of their mean values. Results: This study consisted of 128 subjects (males 57, females 71) with mean age of 21.62 ± 1.75 years, mean weight 59.71 ± 9.97 kg, mean height 164.68 ± 9.30 cm and Body mass index 21.91 ± 2.38 kg/m 2. Fowler's posture showed significantly (P < 0.05) higher value in all spirometric parameters as compared to other two postures. Outcome of the study showed all spirometric parameters value-greater in the Fowler's posture than that of Supine or Crook-lying posture. Conclusion: The implication of this research is that it will meet the need of selection of the most suitable substitute posture for better pulmonary functioning in bedridden people.
Breathing exercises: influence on breathing patterns and thoracoabdominal motion in healthy subjects
Brazilian Journal of Physical Therapy, 2014
| Background: The mechanisms underlying breathing exercises have not been fully elucidated. Objectives: To evaluate the impact of four on breathing exercises (diaphragmatic breathing, inspiratory sighs, sustained maximal inspiration and intercostal exercise) the on breathing pattern and thoracoabdominal motion in healthy subjects. Method: Fifteen subjects of both sexes, aged 23±1.5 years old and with normal pulmonary function tests, participated in the study. The subjects were evaluated using the optoelectronic plethysmography system in a supine position with a trunk inclination of 45° during quiet breathing and the breathing exercises. The order of the breathing exercises was randomized. Statistical analysis was performed by the Friedman test and an ANOVA for repeated measures with one factor (breathing exercises), followed by preplanned contrasts and Bonferroni correction. A p<0.005 value was considered significant. Results: All breathing exercises significantly increased the tidal volume of the chest wall (V cw) and reduced the respiratory rate (RR) in comparison to quiet breathing. The diaphragmatic breathing exercise was responsible for the lowest V cw , the lowest contribution of the rib cage, and the highest contribution of the abdomen. The sustained maximal inspiration exercise promoted greater reduction in RR compared to the diaphragmatic and intercostal exercises. Inspiratory sighs and intercostal exercises were responsible for the highest values of minute ventilation. Thoracoabdominal asynchrony variables increased significantly during diaphragmatic breathing. Conclusions: The results showed that the breathing exercises investigated in this study produced modifications in the breathing pattern (e.g., increase in tidal volume and decrease in RR) as well as in thoracoabdominal motion (e.g., increase in abdominal contribution during diaphragmatic breathing), among others.
Effect of Different Head-Neck Postures on the Respiratory Function in Healthy Males
BioMed Research International, 2018
Normal respiration is a very intricate function that comprises mechanical as well as nonmechanical components. It is shown to be affected by various factors including age, lifestyle, disease, and change in posture. With the increased use of hand held devices, everyone is prone to poor sitting postures like forward head posture. The purpose of this study was to evaluate the effect of assumed forward head posture and torticollis on the diaphragm muscle strength. A sample of 15 healthy males, aged 18-35 years, was recruited for this study. All subjects performed spirometry to measure the forced expiratory volume in 1 second (FEV1), the forced vital capacity (FVC), and FEV1/FVC ratio. SNIP was measured during upright sitting, induced forward head posture, and torticollis. Subject’s mean age (SD) was 23(6) years. The SNIP score of the subjects during sitting with FHP was lower as compared to that during upright sitting. It decreased significantly during induced right torticollis position...

Objective. The present study compared the effects of upright and slouched sitting postures on the respiratory muscle strength in healthy young males.Methods. A total of 35 adult male subjects aged 18–35 years participated in this study. Respiratory muscle strength was determined by measurement of sniff nasal inspiratory pressure (SNIP) using a MicroRPM device in the upright and slouched sitting positions. The subjects were asked to perform the pulmonary function test including peak expiratory flow (PEF), forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio at baseline. Body composition was also determined.Results. There was a significant difference of SNIP score between upright sitting and slouched sitting positions (p=0.04). The mean difference of SNIP score between upright sitting and slouched sitting positions was 8.7 cmH2O. Significant correlations were found between SNIP in upright sitting and FEV1% predicted values [R= .651], SNIP in s...
Influence of Postural Training of Diaphragm on Functional Lung Capacity
Alternative & Integrative Medicine
Breathing is one of the basic life functions. High demands are placed on the respiratory system when increased value of power for example in sport. The main inspiratory muscle is the diaphragm, which performs this function in addition to other functions, mainly postural and sphincter. The aim of this study was to assess the effect on functional capacity of the lung after postural therapy. Trial involved 35 male elite athletes, 25 of which formed the experimental group and 10 was control group. Input and output measurements were identical and methodically divided into two main areas. Postural tests reported in the literature by prof. Kolar and spirometric test. The tests were carried out under constant conditions, and in the same time. The experimental group received postural training lasting six weeks. Comparing the results after completing postural training, we observed differences in postural execution like in spirometry tests in favor of the experimental group. Based on the results of our studies we suggest that postural training of diaphragm have a positive effect on the functional capacity of the lungs. Changes were not statistically significant at all endpoints. This may be caused by tested of elite athletes compared with the possible outcome of the general population. Individuality subjects and their psychosocial conditions during testing could also influence the outcome in a positive or negative direction.
