regression equation for the estimation of maximum oxygen uptake

ABSTRACT

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. Forty female college students [age range, 20.42 tilde 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. 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. 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
