A Regression Equation for the Estimation of Maximum Oxygen Uptake in Nepalese Adult Females

PURPOSE: Validity of the 20-meter multi stage shuttle run test (20-m MST) has not been studied in Nepalese population. The purpose of this study was to validate the applicability of the 20-m MST in Nepalese adult females. METHODS: Forty female college students (age range, 20.42 ~24.75 years) from different colleges of Nepal were recruited for the study. Direct estimation of VO(2) max comprised treadmill exercise followed by expired gas analysis by scholander micro-gas analyzer whereas VO(2) max was indirectly predicted by the 20-m MST. RESULTS: The difference between the mean (±SD) VO(2) max values of direct measurement (VO(2) max = 32.78 +/-2.88 ml/kg/min) and the 20-m MST (SPVO(2) max = 32.53 + /-3.36 ml/kg/min) was statistically insignificant (P>0.1). Highly significant correlation (r=0.94, P<0.01) existed between the maximal speed of the 20-m MST and VO(2) max. Limits of agreement analysis also suggest that the 20-m MST can be applied for the studied population. CONCLUSION: The results of limits of agreement analysis suggest that the application of the present form of the 20-m MST may be justified in the studied population. However, for better prediction of VO(2) max, a new equation has been computed based on the present data to be used for female college students of Nepal.
