Introduction: Our human body is an amazing machine, in which perfectly coordinated events will occur simultaneously. Swimming is a sport which is suitable for people of many different ages, and tness levels. Regular swimming produces many changes in the body. It benets the upper body, torso and legs together and it will improve general strength, lung capacity, stamina and cardiovascular tness. Swimming is an aerobic exercise and it has a signicant effect on respiratory functions that helps the lungs to use oxygen efciently. Aim and objectives:Aim of the present study is to compare the Pulmonary Function Tests of swimmers and non-swimmers and to know whether swimming brings any changes in the pulmonary function tests .Materials and Methods: The present study is a cross sectional study .The total sample size is 100. Swimmers (subjects) are 50 and non-swimmers (controls) are 50 in number. Swimmers are selected from N.T.R.Stadium Swimming Pool, Guntur and Guntur Club Swimming pool, Guntur. Hundred subjects were screened for the study and 50 were selected as subjects. The Pulmonary Function Tests was conducted in the Infectious Disease Hospital, Guntur. Summary and Conclusion: In our study, there is a signicant increase in pulmonary function tests in swimmers compared to non – swimmers.

Objective:Nemaline myopathy (NM) is a rare neuromuscular condition with clinical and genetic heterogeneity. To establish disease natural history, we performed a cross-sectional study of NM, complemented by longitudinal assessment and exploration of pilot outcome measures.Methods:Fifty-seven individuals with NM were recruited at two family workshops, including 16 examined at both time points. Subjects were evaluated by clinical history and physical examination. Functional outcome measures included the Motor Function Measure (MFM), pulmonary function tests (PFTs), myometry, goniometry, and bulbar assessments.Results:The most common clinical classification was “typical congenital” (54%), whereas 42% had more severe presentations. 58% of individuals needed mechanical support, with 26% requiring wheelchair, tracheostomy, and feeding tube. The MFM scale was performed in 44/57 participants and showed reduced scores in most with little floor/ceiling effect. Of the 27 individuals completing PFTs, abnormal values were observed in 65%. Lastly, bulbar function was abnormal in all patients examined, as determined using a novel outcome measure. Genotypes included mutations in ACTA1 (18), NEB (20), and TPM2 (2). Seventeen individuals were genetically unresolved. Patients with pathogenic ACTA1 and NEB variants were largely similar in clinical phenotype. Patients without genetic resolution had more severe disease.Conclusion:In all, we present a comprehensive cross-sectional study of NM. Our data identify significant disabilities and support a relatively stable disease course. We identify a need for further diagnostic investigation for the genetically unresolved group. Lastly, MFM, pulmonary function tests, and the slurp test were identified as promising outcome measures for future clinical trials.

Background: Why is bodyweight not a predictor of lung function, while height, sex, race, and age are predictors of lung capacity and function? In this study, we want to investigate the association between body composition and pulmonary function. And, as much as possible, answer the question of why bodyweight is not predictive of lung function. Methods: This cross-sectional study was performed among 2967 employees of Tehran University of Medical Sciences (TUMS) who participated in the TUMS Employees Cohort (TEC) study. The body composition of the participants was measured using the Bioelectrical Impedance Analysis (BIA) method. Anthropometric variables were also measured as a confounder. The pulmonary function of participants was assessed by a forced spirometry test. Results: The correlation of BIA values including fat-free mass and total body water with a pulmonary function such as FEV1, FVC, and FEF25-75 is higher than most anthropometric values such as weight, wrist circumference, and the waist to hip ratio. Also, in regression analysis, age and sex had an association with pulmonary function, but the weight did not show a significant relationship. On the other hand, fat-free mass and visceral fat were significantly associated with pulmonary function. One is direct and the other is inverse. Conclusion: We observed a negative association between visceral fat and pulmonary function tests and a direct association between Fat-free mass pulmonary function tests (FEV1 and FVC) adjusted for age, sex, and anthropometric indices.

A multicentre, cross-sectional study was carried out in six centres across Canada to establish a national standard for pulmonary function tests using healthy, lifetime nonsmokers, with each centre aiming to test 10 men and 10 women from each decade from 20 to 80 years of age. Data from each centre were used to derive prediction equations for each centre, and pooled data from all centres (total: 327 women and 300 men) were used to derive Canadian predicted equations. The predictive models were compared with three widely used published models for selected tests. It was found that, in general, the equations modelled for each centre could be replaced by the models obtained when pooling all data (Canadian model). Comparisons with the published references showed good agreement and similar slopes for most tests. The results suggest that pulmonary function test results obtained from different centres in Canada were comparable and that standards currently used remain valid for Canadian Caucasians.

Background. Since nontuberculous mycobacterial pulmonary disease (NTM-PD) is a condition with increasing morbidity, a more detailed knowledge of radiological aspects and pulmonary function plays a relevant role in the diagnosis and appropriate therapeutic management of these patients. Objectives. The purpose of this study was to evaluate changes in lung parenchyma through computed tomography (CT) densitometry and, secondarily, to analyze its correlation with pulmonary function testing (PFT) in patients with NTM-PD. Methods. This is a cross-sectional study in which 31 patients with NTM-PD and 27 controls matched by sex, age, and body mass index underwent CT pulmonary densitovolumetry and pulmonary function tests including spirometry and body plethysmograph. Results. Based on the total lung volume (TLV) and total lung mass (TLM) measurements, the cumulative mass ratios were calculated for 3% (M3), 15% (M15), 85% (M85), and 97% (M97) of the TLV. We also calculated the complement, which is represented by TLM (100%) minus the mass of 15% (C85) or 3% (C97) of the TLV. Patients with NTM-PD presented lower values ​​of M3 and M15 than controls, with greater significant differences in the apical third and middle third measurements. Compared to controls, patients with NTM-PD showed higher values ​​of C85 and C97, although significant differences were observed only in the basal third measurements. There were negative correlations of total lung capacity with M3 and M15 in the middle third and apical third measurements. There were positive correlations of residual volume and airway resistance with M3 at the apical third measurement. Conclusions. Patients with NTM-PD show reduced lung mass and increased lung mass in the apical and basal regions of the lungs, respectively. Furthermore, there is a relationship between lung mass measurements and pulmonary function parameters.

Background: Ethnicity is seen to effect normal reference values and pre­diction equations of pulmonary function tests (PFTs). The normal refer­ence of PFTs among mongoloid and non mongoloid group of Dharan is not available. The aim of the study was to find out the normal reference val­ues of two groups in Dharan and also to find out the correlation of height, weight and body surface area with different PFT parameters. Methods: This cross-sectional study was conducted among 250 (125 mongoloids and 125 non mongoloids) healthy male subjects. Convenient sampling technique was done. Every 5th patient attendant who was per­manent resident of Dharan coming to clinical Physiology lab was selected as subject in each group. Portable PFT machine (CHESTOGRAPH, HI-101 Spirometry system) was used for measurement of our test. The test was conducted according to European Respiratory Society (ERS)/American Thoracic Society (ATS criteria. Results: Independent sample t-test was used to compare means be­tween two groups. There was significantly more height (165.30±8.21 vs 161.43±7.35), p <.05], weight [(59.29±11.64 vs 55.32±10.75), p<.05andbody surface area [(1.64±.172Vs1.57±.149), p<.05], in the non-mongoloid group compared to mongoloid group. PFT param­eters were also higher in non-mongoloid group VC [(3.3982±.70725 Vs3.0982±.78832) p<.05], FVC [(3.2798±.74312 Vs 2.988±.81970), p <.05], and FEV1 [(3.0668±.72044 Vs 2.7861±.83061) p<.05]. The prediction equations were also calculated for both groups. Conclusions: There was difference in PFT parameters between two groups. Prediction equations were also different in both groups.
