The purpose of this study was to examine the difference of cardiorespiratory function to the physical fitness grade of elementary school girls in a bid to lay the foundation for improving school physical education activities. The subjects in this study were 10 students who were selected by random sampling from a school sixth year girls in M elementary school. Out of them, five children are high grade in physical fitness, and the others are low grade. To assess their cardiorespiratory function, a treadmill made by Quinton in the United States was employed. As for exercise load, a gradual workout test was conducted according to KISS(re) protocol. The data were analyzed with SPSS 12.0K program, and Mann-Whitney U Signed Ranks Test was employed, which was a nonparametric test. The level of significance was set at p<.05. There was no significant difference of oxygen intaking(VO2) between grades. There was no significant difference of oxygen intaking in a weight(VO2/kg) and METs in rest stage, stage 1, 2, 3, 4 and recovery stage, but in a stage 5, appeared significant difference. The difference of VCO2 appeared high value in the high grade in every stage, but both grades appeared no significant differences. The VE appeared no significant difference in every stage. The RER appeared in a stage 4, appeared significant difference.
