Background and Objectives: Now a day’s people are involved in various activities for fitness. In literature, very few studies have been done to compare the various lung volumes of swimmers with those who are involved in gymnasium; hence the present study was taken up.

Method: The present study was carried out in the department of physiology, M.G.M. Medical College and M Y Hospital, Indore with recruitment of 60 subjects. The subjects were categorized into 2 groups – one having those involved in gymnasium and other having swimmers - each of 30. All the subjects were involved in their respective exercise for a period of minimum two years. Various lung volumes and capacities were measured by spirometer and statistically analyzed.

Results: It was observed that lung volumes of swimmers were greater than those who were involved in gymnasium and the difference was statistically significant.

Interpretation and Conclusion: from the present study it can be concluded that swimming is better than exercise in gymnasium as far as lung functions are concerned.
