Abstract

Six minute walk test (6MWT) is the easiest tool utilized for assessing the functional capacity in the routine clinical practice. The present study aims at assessing the cardio-respiratory capacity in non obese and obese subjects using 6MWT. 22 healthy subjects in age group 17-25 years participated in the study (11 non obese, 11- obese). The written consent was taken from those healthy subjects willing to participate in the study. An anthropometric measurement was taken prior the test. Pre test vital parameters like pulse rate (PR), respiratory rate (RR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and rate of perceived exertion (RPE) was noted on modified Borg’s Scale 0-10. General instruction before the 6MWT and the 6MWT was performed according to ATS guidelines. Significant difference was noted between non obese and obese individuals in their cardio respiratory effort and the capacity and also in the actual 6MWD and the Predicted 6MWD calculated.6MWD showed strongest negative correlation with weight, BMI, post test PR, RR, RPE. No significant difference was found between males and females. The 6MWT is a simple reliable tool that can be used routinely for assessing cardio respiratory capacity and prevent from the risk factors associated with obesity.
