Evaluation of pulmonary function tests in long and short distance runners

Abstract

Physical exercise has been reported to improve many health indices and well-being of individual of any age. Among various physical exercises, running is hugely popular and convenient leisure time activity. Running reduces the risk of respiratory illness. Runners have increased pulmonary/respiratory capacity compared to non-exercising individuals. 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.The study included a total of 50 each of long and short distance runners. Additionally, 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).All PFT indices 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 and short distance runners as compared to controls.running being an aerobic exercise has beneficial effect on respiratory system. Both regular long distance and short distance running enhance the pulmonary capabilities of an individual. The study emphasizes on modification of life style from sedentary to regular physical exercise for improving pulmonary functions.
