Abstract: Objective: to analyze the correlation of the number of steps, peak oxygen uptake (VO2peak) in 6-minute stairs climbing and descending test (6MSCDT) with the maximal oxygen uptake (VO2max) in Bruce plan and to establish the regression equation for the VO2max speculation. To explore whether 6MSCDT can accurately reflect the human heart and lung endurance so as to provide new ideas for the perfection of the simplified heart and lung endurance test method. Methods: randomly recruited 69 volunteers to receive the 6MSCDT and VO2max test, calculated the6MSCDT results, and then compared their correlation with the VO2max in the Graded Exercise Testing (GXT) and made a stepwise regression analysis. Results: The 6MSCDT peak oxygen uptake (VO2peak)and the GXT VO2max is highly correlated (r=0.911,P<0.01); the number of steps in the 6MSCDT is highly correlated with the relative VO2peak (r=0.751,P<0.01); the number of steps in the 6MSCDT and the GXT VO2max is highly correlated (r=0.556,P<0.01). The regression equation for VO2maxspeculation, which uses weight, number of steps and gender as the variables (R=0.888,R2=0.789, Modified R2=0.779,SEE=0.408L/min), was established. Conclusion: 6MSCDT can be used to speculate the VO2max, and can be used as a method of evaluating cardiovascular endurance.
