摘要

The maximal oxygen consumption (VO_(2) max) has been considered the single best indicator of the cardio respiratory fitness. Maximal oxygen consumption (VO_(2) max) is the maximum amount of oxygen a person can intake and utilise during intense exercise.Aim: To estimate and compare VO_(2) max measured by using direct and indirect methods. Materials and Methods: A prospective cross-sectional pilot study in which total of 100 apparently healthy students (male and female) were recruited from RUHS-College of Medical Sciences, Jaipur from January 2019 to August 2019. VO_(2) max of each participant was determined. Direct estimation of VO_(2) max comprised of sub-maximal exercise test on treadmill using gas analyser whereas VO_(2) max was indirectly predicted by standard protocol of Queen College step Test (QCT) with a gap of four days in between the tests. Collected data were entered in Microsoft-Excel and Paired t-test was used for statistical analysis of data.Results: The mean value of VO_(2) max (mL/kg/min) using direct method was 44.66?±9.25 and that of using indirect method was 48.00±8.02. There was statistically very significant difference between two methods of VO_(2) max estimation (p=0.0032). Mean value of VO_(2) max for males was 47.56±8.37 mL/kg/min and for females it was 37.62±7.40 mL/kg/min, which was found statistically significant (p=0.0001) higher in males than in females.Conclusion: From the present investigation it may be concluded that the actual VO_(2) max is lower than the predicted VO_(2) max from the QCT which suggest that the prediction equation is not applicable to the studied population due to difference of ethnicity. With the help of estimated VO_(2) max we can find out physical fitness in individuals and creating awareness about physical activity and life style modification for primary prevention of cardiovascular, metabolic and mental disorders.
