【摘要】：背景:心肺運動試驗在評價人的心肺功能方面起著重要的作用,但需要昂貴的儀器和專業(yè)測試人員才能完成,且需要受試者達到極量強度,所以尋找一種亞極量水平,且操作簡便,費用低廉,容易推廣使用的運動試驗方法迫在眉睫。目的:通過比較心肺運動試驗與6 min上下樓梯試驗的最大攝氧量,探討2種不同試驗方法評價心肺功能的一致性。方法:隨機招募67名志愿者,按Bruce方案進行心肺運動試驗,檢測每位受試者的最大攝氧量,再進行6 min上下樓梯試驗,測量每位受試者在上下樓梯過程中的最大攝氧量,將心肺運動試驗所測得的最大攝氧量與6 min上下樓梯試驗所測得的最大攝氧量進行比較。結(jié)果與結(jié)論:6 min上下樓梯試驗所測得的最大攝氧量小于心肺運動試驗所測得的最大攝氧量(P0.01);6 min上下樓梯試驗的最大攝氧量與心肺運動試驗的最大攝氧量呈正相關(r=0.911,P0.01);2種測試方案下獲得的最大攝氧量具有高度相關關系且一致性較好。因此可以用6 min上下樓梯試驗來推測最大攝氧量,并且這可能成為一種評價心肺功能的有效方法。
[Abstract]:Background: cardiopulmonary exercise test plays an important role in evaluating human cardiopulmonary function, but it needs expensive instruments and professional testers to complete, and the subjects need to reach the maximum intensity, so it is urgent to find a submaximum level, simple operation, low cost and easy to popularize the exercise test method. Objective: to compare the maximum oxygen uptake between cardiopulmonary exercise test and 6 min staircase test, and to explore the consistency of two different test methods in evaluating cardiopulmonary function. Methods: 67 volunteers were randomly recruited to carry out cardiopulmonary exercise test according to Bruce scheme. The maximum oxygen uptake of each subject was measured by 6 min up and down stairs test. The maximum oxygen uptake of each subject in the process of going up and down stairs was measured. The maximum oxygen uptake measured by cardiopulmonary exercise test was compared with the maximum oxygen uptake measured by 6 min up and down stairs test. Results and conclusion: the maximum oxygen uptake measured by 6 min up and down stairs test was lower than that measured by cardiopulmonary exercise test (P 0.01), and the maximum oxygen uptake by 6 min up and down stairs test was positively correlated with the maximum oxygen uptake by cardiopulmonary exercise test (r 鈮，
