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.
The purpose of this study was to validate the applicability of the 20-m MST in Indian adult female.
For application of direct method cross over design was followed. For validity of the results repeatability was used.
32 female university students (age range 20.4 approximately 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.
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.
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 insignificant (p>0.10). Limits of agreement analysis also suggest that the 20-m MST can be applied for use with the studied population.
The results suggest that the application of the present form of the 20-m MST be justified 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.
印度科学家尚未使用20米多级往返跑测试（20 - m MST），且该测试在任何印度人群中的有效性都未得到研究。
本研究旨在验证20 - m MST在印度成年女性中的适用性。
采用直接法交叉设计进行应用研究。通过重复性来验证结果的有效性。
从印度西孟加拉邦三所不同大学招募了32名女大学生（年龄范围约20.4至24.8岁）参与研究。通过跑步机运动后用Scholander微量气体分析仪进行呼出气体分析直接估计最大摄氧量（VO2 max），而通过20 - m MST间接预测VO2 max。
采用配对t检验、Pearson积矩相关、线性回归统计以及Bland - Altman一致性界限方法对数据进行统计分析。
直接测量的平均（标准差）VO2 max值（VO2 max = 32.84 ± 2.92 ml/kg/min）与20 - m MST的预测值（SPVO2 max = 32.60 ± 3.40 ml/kg/min）之间的差异无统计学意义（p > 0.10）。一致性界限分析也表明20 - m MST可应用于所研究的人群。
结果表明，在本研究人群中，当前形式的20 - m MST的应用是合理的。基于现有数据，已计算出一个新的方程，用于更好地预测印度女大学生的VO2 max。
