用20-MST预测大学生最大吸氧量的研究

Study on Predicting University Students' Maximal Oxygen Uptake by Using the Multistage 20 Meter Shuttle Run Test

以103名（男52人，女51人）来自南方的大学生自愿者为受试，建立了用在塑胶跑道上进行的20-MST预测大学生的Vo2max的线性回归模型：Vo2max（ml·kg^-1·min^-1）=-21.960＋5.739×MAS（km·h^-1），r=0.888,P〈0.000，全距10.0～15.0km·h^-1。统计学检验表明该模型满足线性回归模型独立、线性、正态和等方差的四个假设务件，具有良好的适合性。用该模型预测30名大学生自愿者的VO2max，其结果也表明20-MST是预测大学生的VO2max的有效方法。

The study built up the linear regression model forecasting from 20-MST by conducting on synthetic surface track according to 103 university students volunteers＇ （51 females and 53 males ） data ： （ml.kg^-1.min^-1） = -21.960＋5.739×MAS（km.h^-1）, r =0.888, P 〈 0.000, range 10.0～15.0 km.h^-1. Statistical analysis expressed that the model satisfies the four assumption conditions： independence, linear, normal and homogeneity, has a good suitability. Predicting 30 university students volunteers＇ using the model reaches such a result that 20-MST is a valid method to predict the uni-versity students＇.
