To compare physiological responses during a treadmill cardiopulmonary exercise test (CPX), 6-minute walk test (6MWT), and timed up and go test (TUGT) in individuals referred for unexplained breathlessness and symptom limited treadmill exercise testing. Heart rate (HR), oxygen consumption (V̇O), carbon dioxide production (V̇CO), respiratory exchange ratio (RER), minute ventilation (V̇), systolic blood pressure (SBP), and rating of perceived exertion (RPE) were recorded throughout each test. Each test demonstrated a significant increase ( < 0.01) in the cardiopulmonary (V̇O, V̇CO and V̇, RPE, SBP, and HR) and perceptual (RPE) responses from rest to end exercise. The increase in cardiopulmonary and perceptual responses was greatest for the CPX with significantly smaller responses demonstrated during the 6MWT ( < 0.01) and even smaller responses for the TUGT ( < 0.01 vs CPX and 6MWT). Not surprisingly, the treadmill CPX results is the greatest physiological response in our group. Despite being of short duration, the TUGT results in an increased physiological response.
为比较在因不明原因呼吸困难而接受症状限制的跑步机运动测试的个体中，跑步机心肺运动试验（CPX）、6分钟步行试验（6MWT）和定时起立行走试验（TUGT）期间的生理反应。在每项测试过程中记录心率（HR）、耗氧量（V̇O）、二氧化碳产生量（V̇CO）、呼吸交换率（RER）、分钟通气量（V̇）、收缩压（SBP）和主观用力程度分级（RPE）。每项测试均显示，从休息到运动结束，心肺功能（V̇O、V̇CO和V̇、RPE、SBP和HR）和感知（RPE）反应均显著增加（<0.01）。CPX的心肺和感知反应增加最大，6MWT期间的反应显著较小（<0.01），TUGT的反应甚至更小（与CPX和6MWT相比，<0.01）。不出所料，跑步机CPX结果是我们组中最大的生理反应。尽管TUGT持续时间短，但它会导致生理反应增加。
