摘要：
Objects: Analysis the correlation of the step index, 1000m run, 12min run with maximal oxygen uptake(VO(2max)) in high school boys, for the purpose of providing students, teachers and parents with more convenient and effective testing method to command students' physical health status. Subjects and Methods: Adopted simple random sampling, and extract boys of seventh grade, eighth grade, sophomore and junior from two urban and two rural schools in Changsha area as subjects, with 240 in total. Measured the students' step index, 1000m, 12min run, and directly measured their VO(2max); then calculated and processed data by such methods as comparative method and correlation analysis. Results: 1) Step index, which has no statistics relativity with the VO(2max), 1000m run and 12min run, also, can not reflect discipline of ageing changes. 2) The correlation coefficient of 1000m run with the maximal oxygen uptake is -0.716, is high negative correlation(P<0.01). Similarly, the correlation coefficient of 1000m run with 12min run is -0.77, is high negative correlation too(P<0.01). The correlation coefficient of 12min run with VO(2max) is 0.731, is highly positive correlation (P <0.01). Conclusions: 1) The step index cannot exactly reflect endurance quality level and cardiovascular function level in high school boys; 2) Both 1000m and 12min run may be acted as the indexes to indirectly determine VO(2max), furthermore, there is much stronger replacement within.
