Pulmonary function tests (PFT) serve as a tool of health assessment and also to some extent as a predictor of survival rate. PFT tend to have a relationship with life-style such as regular exercise and non-exercise. To be physically active is the body’s most common physiological stress, and it places major demands on the cardiopulmonary system. Spirometry is pivotal to the screening, diagnosis and monitoring of respiratory diseases and is increasingly advocated in primary care practice. Spirometry is considered the most practical test of assessing the respiratory function. So the present study was carried out to evaluate the lung function between physically active and sedentary females using pulmonary function test.
Methods: The sample consisted of 62 female individuals of age between 25 years to 35 years. In group A Actively working female subjects were included and in group B sedentary females were included. Before 6 min walk test, all subjects of both the groups were asked for Pre PFT readings. After completion of 6 min walk test, all subjects of both the groups were again asked for Post PFT readings. Lung function parameters like Forced Expiratory Volume in 1 second (FEV1), Forced Vital Capacity (FVC), FEV1 / FVC Ratio and Peak Expiratory Flow Rate (PEFR) were recorded. Pulmonary function were recorded in the same time of the day in sitting position at rest and immediately after 6min walk test.
Results: The data was analysed by SPSS VERSION 20. Pre and post PFT readings within group was done using paired t test which shows highly significant difference in both groups. Comparison between groups was done using independent t test which shows significant differences in both groups for all variables.
Conclusions: The results of this study shows significant difference within and between the groups. However Group 2 with sedentary females is found to have lower values compared to the group 1 for all variables.
