Abstract:

BACKGROUND: Cardiopulmonary exercise test plays a significant role in the evaluation of cardiopulmonary function, but it is limited by expensive equipments and professional personnel, and moreover, the subjects need to bear the maximal exercise intensity. As a result, it is extremely urgent to find a submaximal exercise test characterized by simple operation, low cost and easy to be popularized and used.
OBJECTIVE: To compare the maximal oxygen uptake in cardiopulmonary exercise test and 6-minute stair climbing and descending test.
METHODS: Sixty-seven volunteers were recruited to undergo the cardiopulmonary exercise test using the Bruce protocol, and then, the maximal oxygen uptake was detected. After that, all the participants were subjected to 
6-minute stair climbing and descending test, followed by determination of the maximal oxygen uptake.
RESULTS AND CONCLUSION: The maximal oxygen uptake in the cardiopulmonary exercise test was significantly higher than that in the 6-minute stair climbing and descending test (P < 0.01), and there was a highly positive correlation and consistency between the maximal oxygen uptakes in the two tests (r=0.911, P < 0.01). Therefore, 6-minute stair climbing and descending test can be used to detect the maximal oxygen uptake, which may become an effective method for evaluating cardiopulmonary function.
