Effects of Training on Pulmonary Function Test in Long Distance Runners

Background: Running is one of the most popular exercises practiced across the world. Owing to regular exercise during running, long distance runners usually have increased pulmonary/respiratory capacity compared to non-exercising individuals. The present study was conducted in a tertiary care academic hospital with an aim to assess pulmonary function test in long distance runners. Methods: A total of 50 long distance runners and 50, age matched individuals with leisure-time physical activity or activities done for less than 20 minutes or less than 3 times/week were included in the study. The PFT was performed by using Medspiror (Computerized spirometry) after reinforcing the method of test to each participant. Result: All parameters of PFT like forced vital capacity (FVC), forced expiratory volume in 1st second (FEV1), forced expiratory volume in three second (FEV3), peak of expiratory flow rate (PEFR) and FEV1/FVC ratio were significantly high in long distance runners and controls. Conclusion: Physical exercise in any form has positive effect on respiratory system of an individual. As running improves/enhances vigor of respiratory muscles, it increases the function of pulmonary system. The current study, underscores the importance of regular running to improve the pulmonary function.
