The reliability of cardiopulmonary values during serial exercise testing has been examined in healthy subjects and in pathological conditions. Three to four percent variability between tests may be attributed to biological factors and up to 8% variability is considered to be acceptable within pathological populations. In a recent study in our lab, patients with Chronic Fatigue Syndrome (CFS) showed variability scores of up to 27% on repeated exercise tests. In other studies repeated tests were done with several days in between, so that it is not known if exercise tests can be reproduced within 24 hours. PURPOSE: The purpose of this study was to establish the degree of variability among cardiopulmonary measures during an exercise test-retest paradigm in healthy, physically active women, with the exercise test separated by 24 hours.
