Correlation of Wassermans equation and directly measured VO2 max in Indian population - A pilot study
Journal Title: International Journal of Biomedical and Advance Research - Year 2017, Vol 8, Issue 1
Abstract
Purpose of study: VO2 max can be measured by direct and indirect method. Maximal oxygen uptake (VO2 max) during a graded maximal exercise test is the objective gold standard method to assess cardio respiratory fitness. Direct method (open circuit spirometry) requires specialized trained equipment, trained personnel and is expensive. VO2 max is measured indirectly through these tests using regression equations. These regression equations have been formulated on the basis of normative data obtained from Caucasian population. Aim and Objective: To find out the correlation between observed VO2 max and predicted VO2 max in Indian population. Study design: Cross sectional study Methodology: 22 college students aged between 18-25 years were included after fulfilling the selection criteria demographic data was recorded and vitals were taken before, during and after the procedure. In this VO2 max was calculated directly by gas analyzer using AD instrument and indirectly by Wassermans equation (non exercise based) and data was further analysed stastically. Result: The Interclass Correlation found between direct and indirect methods was 0.39 which shows that there is poor limit of agreement between the two methods. Conclusion: The Wassermans equation was inapplicable to evaluate VO2 max for the students included in the study.
