Abstract:
The present study was designed to determine Comparison of vital capacity between tobacco smokers and non-tobacco smokers. The study was conducted on total fifty (N=50) subjects are selected 25 tobacco smokers and 25 non tobacco smokers they are from Punjabi university Patiala between age group of 20 - 30 years from the campus and nearby the campus of Punjabi University Patiala were selected as subjects. To know the difference between vital capacity of tobacco smokers and non -tobacco smokers, researcher had selected following two vital capacity parameters as dependent variables FVC (Force Vital Capacity), PEFR (Peak Expiratory flow Rate.. To effect mean, standard deviation and unpaired t–test were employed. The level of signifance choose in to test the hypotheses was 0.05, P < 0.05. Results of the study explicated statistically that there was significant difference in FVC (Force Vital Capacity. However, significant difference was found in PEFR (Peak Expiratory flow Rate) of Tobacco Smokers and Non -Tobacco Smokers.
