EFFECT OF 10 MINUTETRADEMILL WALKING EXERCISE ON PEFR IN HEALTHY YOUNG ADULT IN RELATION WITH BMI
Journal Title: International Journal of Basic and Applied Physiology - Year 2016, Vol 5, Issue 1
Abstract
Background and Objectives: Peak expiratory flow rate (PEFR) is the largest expiratory flow rate achived with a maximally forced effort from a position of maximal inspiration(1).PEFR is particularly susceptible to dynamic compression of the extrapulmonary airways and fat laid down in mediastinum, around the heart & pleural space, above diaphragm. The main objective of the present study was to see the effect of exercise on PEFR and also to compare the changes in different groups of BMI. Materials and Methods: In the present study 200 healthy subjects of 18-24yrs of age were selected &their BMI were measured. The subjects then went through 10 minutes of treadmill under Bruce protocol and their PEFR were recorded before and after exercise with spirometer. Results: In the present study it had been found that there was significant increase in PEFR after exercise. The mean PEFR before and after exercise were 6.01±1.18 L/sec and 6.90±1.12 L/sec respectively. When the PEFR of the study population was compared with the BMI of the study population it showed a negative relation with BMI i.e with increase in BMI there was decrease in PEFR. This relation was present both before and after exercise. The correlation coefficient between BMI and PEFR before and after exercise were r value -0.8192(p<0.0001) and -0.8086(p<0.0001) respectively. Conclusion: From these we can conclude that BMI has a significant negative effect on the pulmonary ventilation which can overcome by exercise. Regular physical activities should be encouraged in school and colleges for a better health and better future of the young generation
