心肺运动试验与6 min上下楼梯试验评价心肺功能的比较

摘要

背景：心肺运动试验在评价人的心肺功能方面起着重要的作用，但需要昂贵的仪器和专业测试人员才能完成，且需要受试者达到极量强度，所以寻找一种亚极量水平，且操作简便，费用低廉，容易推广使用的运动试验方法迫在眉睫。目的：通过比较心肺运动试验与6 min上下楼梯试验的最大摄氧量，探讨2种不同试验方法评价心肺功能的一致性。方法：随机招募67名志愿者，按Bruce方案进行心肺运动试验，检测每位受试者的最大摄氧量，再进行6 min上下楼梯试验，测量每位受试者在上下楼梯过程中的最大摄氧量，将心肺运动试验所测得的最大摄氧量与6 min上下楼梯试验所测得的最大摄氧量进行比较。结果与结论：6 min上下楼梯试验所测得的最大摄氧量小于心肺运动试验所测得的最大摄氧量(P <0.01)；6 min上下楼梯试验的最大摄氧量与心肺运动试验的最大摄氧量呈正相关(r=0.911，P <0.01)；2种测试方案下获得的最大摄氧量具有高度相关关系且一致性较好。因此可以用6 min上下楼梯试验来推测最大摄氧量，并且这可能成为一种评价心肺功能的有效方法。%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, al the participants were subjected to 6-minute stair climbing and descending test, folowed 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.
