Effect of positive expiratory pressure (PEP) on VO2 max, SPO2, PR of obese class I individuals

Abstract

This study aimed to find out the Effect of PEP breathing on VO2max, SPO2, PR in obese class I individual at Higher educational institutions in Miraj. 40 individuals participated in the study. The VO2max, SPO2 and PR was taken as an outcome measure post Queens’s college step test for assessing the effect of PEP breathing. All the participants were assessed for inclusion and exclusion criteria first. 36 out of 40 participants were included in the study. These 36 participants were further randomly divided into 2 groups of 18 each ie. For PEP breathing and habitual breathing, after 4days the groups were crossed and step test was done again. VO2max, SPO2, PR were measured post-test. PEP breathing was found to be effective. t test was done to compare the observed results of increase in VO2max, SPO2 and decrease in PR. With a P-value of 0.005, 0.002, 0.001* respectively, it revealed that PEP breathing is statistically effective in obese class I individuals.
