Background: The 20-meter multi stage shuttle run test (20-m MST) has not yet been used by Indian scientists and validity of the test has not been studied for use with any of the Indian population.
Aims: The purpose of this study was to validate the applicability of the 20-m MST in Indian adult female.
Materials and methods: For application of direct method cross over design was followed. For validity of the results repeatability was used. Methods and Material: 32 female university students (age range 20.4 ~24.8 years) from three different universities of West Bengal, India were recruited for the study. Direct estimation of VO2 max comprised treadmill exercise followed by expired gas analysis by scholander micro-gas analyzer whereas VO2 max was indirectly predicted by the 20-m MST.
Statistical Analysis: Paired t-test, Pearson’s product moment correlation, linear regression statistics and Bland and Altman approach for limit of agreement were adopted for statistical analysis of the data.
Results: The difference between the mean (SD) VO2 max values of direct measurement (VO2 max = 32.84 ± 2.92 ml/ kg/min) and the 20-m MST (SPVO2 max = 32.60 ± 3.40 ml/kg/min) was statistically insignifi cant (p>0.10). Limits of agreement analysis also suggest that the 20-m MST can be applied for use with the studied population.
Conclusions: The results suggest that the application of the present form of the 20-m MST be justifi ed in the studied population. For better prediction of VO2 max a new equation has been computed based on present data for use with Indian female university students.
