Abstract :

Introduction: Maximal Oxygen Consumption (VO2 Max) is the maximal attainable rate of oxygen consumption during exercise using large muscle groups. It indicates the aerobic capacity. Aims and Objectives: study of Maximal Oxygen Consumption [VO2max] in Obese and non obese individuals at tertiary health care center. Materials and Methods: This was a cross–sectional study carried out in the apparently healthy adults during the one year period i.e. March 2018 to March 2019 so during the one year period there were 100 volunteers enrolled to study. All details of the patients like age, sex, Weight, height, BMI was calculated. All the volunteers were undergone Oxygen Consumption [VO2max] in Obese and non obese individuals. The data was entered to excel sheet and analyzed by unpaired t–test and chi–square test and calculated by SPSS 19 version test. Result : In our study we have seen that The average age was comparable i.e. 39.17±2.39 and 40.13± 3.45 (t=0.54 ,p>0.05);and the proportion of Male : Female was also comparable i.e. 1.78 as to 1.38 (X2=2.34,df=1,p>0.05) , Average BMI In both the groups were comparable i.e. 23.41± 1.98 and 24.38± 2.15 (t=0.27,df=98,p>0.05) . The Maximal VO2 (L/min) was significantly higher in Obese Group i.e. 3.92± 2.34 as compared to Normal i.e. 2.87± 2.45 (t=5.98,p<0.05) where as VO2max/resting VO2 (mL/kg per minute) was 33.2± 1.94 and 48.32± 1.76 (t=6.13,p<0.05); VO2max/resting VO2 was 11.9 ± 2.65 and 13.9 ± 3.75 (t=8.92,p<0.001) was significantly higher in Normal as compared to Obese respectively ; Max O2 pulse (VO2/HR X 103 ) 18.67± 3.52 and 16.13± 2.48 (t=6.29,p<0.05) was significantly higher in Obese. Conclusion : It can be concluded from our study that VO2 Max was significantly higher in Normal individuals as compared to Obese hence obesity may be responsible for the cardio respiratory functions
