A comparative study of lung function test between physically trained and untrained adults

摘要

Background: The maximum lung function for human being reached around the age of 20-25 years. Studies on lung function indicated a progressive age-related functional change of the respiratory physiology. Regular physical activity throughout the life may delay this deterioration of lung function. Objective of the study: The present study was designed to observe the effect of aging on lung function induced by regular physical activity. Methods: Respiratory function was tested by digital spirometer. 479 persons (Male: 246 and Female: 233) ages between 20-70 years were examined at the department labortory, Jadavpur University, Kolkata. 79 persons were excluded from the study due to acute or chronic respiratory disorders and the history of smoking. All the subject were allotted in the five age category (20-29 yrs; 30-39 yrs;40-49 yrs; 50-59 yrs and 60-70 yrs) to observe the age related changes between the trained (male: 100 and female:100) and untrained (male: 100 and female:100) persons. Mean, Standard deviation and 't' test were done to calculate the statistical significance and made a valid conclusion. Result: A slow progressive age related decline were observed in trained group compared to untrained in all the age category for both male and female. Conclusion: From the present study it can be concluded that regular physical activity may delay the age related decline of lung function for all the age groups and promote healthy aging.
