The field of exercise physiology is at the dawn of a new era. Exercise can play a role in shaping one's life style.Jogging, and walking are dynamic exercises, play a dominant role in individual's total health. The pulmonary physicians admit the dynamic exercise is beneficial to prevent respiratory diseases . The dynamic exercise's positive impact includes pulmonary physioloy. The pulmonary function tests evaluate the respiratory system. They are ventilatory function tests. The oxygen consumption and carbon dioxide production may go up to 25 times depending on severity of the exercise and the alveolar and arterial PO2 and PCO2 are maintained normal during the strenuous exercise, by increase in pulmonary ventilation and changes at the tissues level. Materials and Methods: study was conducted on subjects ranging from 24-26 years, 44-46 years and 64-66 years male in good health and their hemoglobin is more than 10gms/ 100ml. Different parameters (FVC, FEV1, FEV1/FVC %, PEF 50%, RR) of the study are recorded on the computerized Spirometer. Results and Conclusion: The results showed significantly increased (p<0.001) mean FVC, mean FEV1, mean FEV% and mean PEF in male atheletes practicing regular dynamic exercise and more so in young persons. This suggests that regular dynamic exercise has improved lung function.
