- Abstract
BACKGROUND: Cardiopulmonary exercise test plays an important role in the evaluation of cardiopulmonary function, but it needs strict laboratory environment, expensive equipment and professional testers. The test requires a maximum tolerance level of the subject, which is more risky. OBJECTIVE: To evaluate the consistency of cardiopulmonary endurance by comparing the maximum oxygen uptake of the cardiopulmonary exercise test with the 6-minute two-step test. METHODS: The study was approved by the Ethics Committee of Beijing Sport University. Sixty-seven volunteers were randomly enrolled and signed the informed consents. The maximal oxygen uptake was measured directly in the cardiopulmonary exercise test according to the BRUCE protocol. A week later, the same group of subjects underwent a 6-minute two-step test and indirectly estimated their maximum oxygen uptake using the reckoning equation. The maximum oxygen uptake of the two test methods was compared and analyzed. RESULTS AND CONCLUSION: (1) The maximum oxygen uptake calculated by 6-minute two-step test was less than that calculated by cardiopulmonary exercise test. (2) There was a positive correlation between the maximum oxygen uptake of by 6-minute two-step test and the cardiopulmonary exercise test (r=0.861, P < 0.01). (3) There was a high correlation and consistency between the two methods (r=0.868, P < 0.01). (4) Therefore, 6-minute two-step test may be used as a sub-maximal load to estimate the level of cardiopulmonary endurance effectively.
