Abstract
Purpose: 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. Methods: Heart rate (HR), oxygen consumption (V̇O2), carbon dioxide production (V̇CO2), respiratory exchange ratio (RER), minute ventilation (V̇E), systolic blood pressure (SBP), and rating of perceived exertion (RPE) were recorded throughout each test. Results: Each test demonstrated a significant increase (p < 0.01) in the cardiopulmonary (V̇O2, V̇CO2 and V̇E, 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 (p < 0.01) and even smaller responses for the TUGT (p < 0.01 vs CPX and 6MWT). Conclusion: 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.
期刊介绍:
Rehabilitation Research and Practice is a peer-reviewed, Open Access journal that publishes original research articles, review articles, and clinical studies in all areas of physical medicine and rehabilitation. The journal focuses on improving and restoring functional ability and quality of life to those with physical impairments or disabilities. In addition, articles looking at techniques to assess and study disabling conditions will be considered.
