Background: Pulmonary function assessment has achieved a lot of importance nowadays owing to a steep rise in air pollution. Lung function parameters tend to have a relationship with lifestyle such as regular exercise and non-exercise. Hence the present study was under taken to assess the effects of exercise in athletes on respiratory system and compared with sedentary group. Aims & Objective: To compare the differences in pulmonary function test among the athletes and sedentary group. Materials and Methods: A total of 152 subjects comprising athletes and sedentary were assessed for pulmonary function test. The parameters used as determinants of lung function were FVC, FEV1, FEV3, PEFR and FVC/FEV1 ratio were recorded as per standard procedure using Medspiror. Results: Pulmonary Function Profile was analyzed and compared between the study groups. In our study the athletic group were having higher mean of percentage value of FVC 88.0 ± 12.8%, FEV1 of 86.8 ± 22.0%, FEV3 of 86.5 ± 13.7 %, PEFR of 93.0 ± 12.8% and FEV1/ FVC ratio of 92.1 ± 4.4% as compared to sedentary group. Conclusion: The FVC, FEV1, FEV3, PEFR and FEV1/FVC ratio were higher in athletes than in the normal sedentary control individuals. This study suggests that regular exercise has an important role in determining and improving lung functions.

Analytical solitary wave solution of the dust ion acoustic waves (DIAWs) is studied in the framework of the damped Korteweg–de Vries–Burgers (DKdVB) equation in an unmagnetised collisional dusty plasma consisting of negatively charged dust grain, positively charged ions, q-nonextensive electrons, and neutral particles. Using Reductive Perturbation Technique, the DKdVB equation is obtained for DIAWs. The effects of different physical parameters such as dust ion collision frequency parameter (\({\nu_{id0}}\)), viscosity coefficient (η10), the entropic index (q), the speed of the travelling wave (M0), and the ratio between the unperturbed densities of the electrons and ions (μ) on the analytical solution of DIAWs are observed. The results of the present article may have applications in laboratory and space plasmas.
