(2) compared the dyspnea rating during ADL and exercise testing in patients with COPD and normal subjects. (3) compared the VO2 of ADL and VO2peak of exercise testing in patients with COPD and normal subjects. (4) related factors analysis of VO2 of ADL. A explored — correlated design was used. VO2 of ADL ( sitting, standing, walking, walking with 2kg goods, and walking upstairs in a two — story building ) and exercise testing were measure in 22 patients with COPD and compared with those of 18 age, weight, height matched control subjects. Data were collected by means of questionaires, VO2 of ADL, and peak exercise testing. Data was analyzed by percentage, mean, standard deviation, T test, and Pearson correlation. The major finding of this study were as follows: (1) mean VO2 of ADL in patients with COPD was: sitting 3.41（+0.82）ml‧kg-1‧min-1, standing 3.67（+0.90）ml‧kg-1‧min-1, walking 10.06（+2.19）ml‧kg-1‧min-1, walking with 2kg goods 10.28（+1.65）ml‧kg-1‧min-1, and walking upstairs 8.16（+1.36）ml‧kg-1‧min-1. (2) The dyspnea rating of ADL and exercise testing in COPD group ( n=18 ) was higher than control group ( n=18 ). We finding dyspnea limits the independent function and activity tolerance in COPD group. (3) There were no differences at VO2 of ADL between the two groups, but VO2peak was significantly lower in the COPD group ( 13.90 + 2.93 ml‧kg-1‧min-1 ) compared with the control group ( 16.15 + 1.86ml‧kg-1‧min-1 ) (p = 0.009). So, the cardiorespiratory function in COPD group was worse than control group. (4) Smoking and regular exercise were correlated with VO2 of ADL in control group. Lung function ( FEV1) and dyspnea rating ( BDI ) were high correlation with VO2peak in the COPD group, and we finding the dyspnea rating was more important than lung function.
