Initially, eleven boy students （12±0.6 yrs） elementary school boys stepping 3 boxes test with 25, 30, 35 centimeter high, respectively; compare the correlation within finishing different high step-boxes frequency time and VO2max and we found that the frequency, and time in 35 cm. high had the highest correlation with VO2max（ r=.86, r=.89; p<.05）. Fifty boys （12.2 ±0.6 yrs）, furthermore, performed 35cm high step test, 800m walk-run test, and treadmill to measure their VO2max. We found that the frequency and time of the exhaustive step test were significantly correlated with VO2max （ r=.79, r=.79, r=.78; p<.05 ）. Finally, randomly select 19 of them （11.8 ±0.5 yrs） performed the 2nd step test and 800m walk-run test to validate the test-retest reliability （ r=.93, r=.94, r=.96; p<.05 ）. The results suggest that to predict VO2max, gradually step test and 800m walk-run test are superior in both validity and reliability. To predict VO2max, the stepwise regression equation was: VO2max（ml/kg/min ）=23.858＋0.02526×step test time （s） ＋0.04199×step test frequency （beat/min） （R=.79, =.63, SE=5.16, F=40.14; p＜.05） VO2max （ml/kg/min ）=54.209 0.01645×step test time （s） －0.07181×800m walk-run （s） （R=.82, =.67, SE=4.86, F=48.39; p＜.05） The gradually step test has the merits: can be used in a group, low place requirement, easy to get equipment, similar procedures with VO2max test in a lab, and external factors can be effectively controlled; then, subjects can do their best to complete their test. It is concluded that the gradually step test, therefore, is one of effective test tools to predict VO2max.
